Fin Regrowth and Algae Questions?

Background: I keep cichlids. My yellow lab got singled out and beat up to the point of being removed to a hospital tank (Sept 18), his tail fin just a muscly stub and his appearance quite emaciated. I believe the tank to be 5 gallons (I initially though it was 10), with a bright light and items recycled from a garage sale (which sat a long time in my basement and were washed). I do water changes every weekend, and the replaced water is from the main tank. The water conditions are good- high hardness and pH, little to no ammonia or nitrate, questionable nitrite. I fed him normal cichlid food for a while, then switched him onto an all-veg diet at the advice of a local fish specialist, who also suggested cranking the temperature a few degrees. I can not do that because I bought a cheap heater which automatically keeps the temperature at 76 degrees Fahrenheit (24.4 degrees Celsius). The guy told me that with the food and heat alterations my fish would be healed in no time. That fish is now nice and filled out, and has about half of a tail whisping behind him. Today I spotted a small patch of what I believe to be cyanobacteria (blue-green algae) in the tank.

My Questions:

How long is he going to take to grow his tail back?? Goodness, I thought it would take maybe 2 weeks!

Is the temperature/heater my problem?

Is there any way I can help him regrow his fin faster?

Is that cyanobacteria dangerous to his health as it is?

Will it take over before my fish is back in ship-shape?

Will my fish carry it over to my other tank? (I have not seen any sign of it there yet, although I use the same siphoning gear for both tanks as well as a planted one).

Would you advise using chemicals to eliminate it?

Thanks!Fin Regrowth and Algae Questions?
The algae won't hurt your fish. I used apple snails or some type of algae eaters to keep my tanks clean. The algae occurs naturally, like in the wild, so it's ok, just unsightly to some people. I always tried to stay away from chemicals. Hope this helps. I used to raise african and south american cichlids.

Get working! You can not cheat on a test. Please give me your teacher's email so I can write him or her to let them know my answers if you want my answers to be given. You need to learn this material as it is relatively basic chemistry.Chemistry.. online test.. have 1 hr to complete.. please help!!!!!!!!!!!?
Sorry, I already have my Ph.D.; I am through with exams.

It's one thing to help a struggling student to gain a better appreciation for the subject, but I wouldn't go so far as to help him get a high mark in a subject he doesn't know that much about. It makes for very incompetent chemists later on. Go do something else, something you're actually good at.Chemistry.. online test.. have 1 hr to complete.. please help!!!!!!!!!!!?
Where I come from, a test, be it online, take=home, or in school, unless stated by the tester, is to be done by a student WITHOUT HELP. If you get such help, you are CHEATING!

That may be OK in your world, but not in mine.

BTW...

how do you find the freezing point of a typical coolant by looking at at its pic. P.S the pic shows degrees in Fahrenheit, from top to bottom +10, 0, -7, -20, -34, and -45. In addition, it also says :

(-34 Fahrenheit) 50% concentration recommended (-37 Celsius)

Having the correct answers for these questions are very significant to me.... so PLEASE! If you can lend me a helping hand... i will appreciate it sooooo much~!!Mechanic questions...need helps!!?
Answer to first question - find new techs , but first change the sending unit . If still low pressure , will need to change gauge .

Second question - should be at least 2 oil changes .

Third question - either tester gauge bad or leak in system

Fourth question - again find new techs - 1 the relief valve is not always in the filter as on some engines it is in the filter housing- 2 relief valve is just that . It relieves excessive pressure .

Fifth question - all of the above or any one of the above

Sixth question - need new techs again . At room temp , stat should be closed and opens slowly as temp goes up

Seventh question - hey , you finally found 2 correct answers

Eighth question -Actually all of those temps could be freeze point depending on the concentration of anti-freeze to water ratio . Most manufacturers recommend a 50/50 concentration , but you need to adjust that depending on where you live .Mechanic questions...need helps!!?
D, B, B, C, C, D, C. You really ought to do your own homework, though!!!!

Will someone REVISE my Paragraph for me Pease?

Just revise and rearrange PLease + thank you

1There are many negative effects linking themselves to the drastic climate change, or Global Warming. These effects include the polar ice caps melting, economic consequences, increased probability and intensity of droughts and heat waves, warmer waters and more hurricanes, and finally, the wide spread of diseases. These are only some of the effects of the climate change, but they can be stopped. It will take time, but there is a number of different ways to stop the change. For instance, doing simple things such as picking up trash in your neighborhood, local park, school, or even just on the sidewalks will make a big difference. There is little doubt that the planet is warming. Over the last century, the planets temperature has risen by around 1 degree Fahrenheit (0.6 of a degree Celsius). The warmest since the mid 1800檚 was the 1990s. The hottest years recorded were 1997, 1998, 2001, 2002, 2003.

The United Nations panel on climate change projects that the global temperatures will rise 3-10 degrees Fahrenheit by the century檚 end - enough to have the polar caps all but melted. If the ice caps melt, a vast majority of our countries borders will be under water. Monuments and great buildings, as well as homes and lives will be under water, including New York City. Experts say that fears surrounding climate change are overblown

Alarming predictions that climate change will lead to the extinction of hundreds of species may be exaggerated, according to Oxford scientists. So now we know what some of the causes are for global warming, how can we as individuals do our part to help save the planet?

The answer is simpler than you may think. You don檛 have to go miles away from home to protest, or spend masses of money. Reduce, reuse and recycle. Only buy what you need; don檛 stock the cupboards with things you may or may not use. Reuse whatever you can, like containers and paper, and recycle what you cannot reuse. It really is as simple as that.

Finally turning off unused sources of power such as televisions and heaters will help the environment, as well as save you money.

Large scale global study shows a massive 50% gap in man made CO2 global warming theory!?

The conclusion, Dickens said, is that something other than carbon dioxide caused much of the heating during the PETM. %26quot;Some feedback loop or other processes that aren't accounted for in these models -- the same ones used by the IPCC for current best estimates of 21st Century warming -- caused a substantial portion of the warming that occurred during the PETM.

No one knows exactly how much Earth's climate will warm due to carbon emissions, but a new study suggests scientists' best predictions about global warming might be incorrect.

The study, which appears in Nature Geoscience, found that climate models explain only about half of the heating that occurred during a well-documented period of rapid global warming in Earth's ancient past. The study, which was published online July 13, 2009 contains an analysis of published records from a period of rapid climatic warming about 55 million years ago known as the Palaeocene-Eocene thermal maximum, or PETM.

%26quot;In a nutshell, theoretical models cannot explain what we observe in the geological record,%26quot; said oceanographer Gerald Dickens, a co-author of the study and professor of Earth science at Rice University. %26quot;There appears to be something fundamentally wrong with the way temperature and carbon are linked in climate models.%26quot;

During the PETM, for reasons that are still unknown, the amount of carbon in Earth's atmosphere rose rapidly. For this reason, the PETM, which has been identified in hundreds of sediment core samples worldwide, is probably the best ancient climate analogue for present-day Earth.

In addition to rapidly rising levels of atmospheric carbon, global surface temperatures rose dramatically during the PETM. Average temperatures worldwide rose by about 7 degrees Celsius -- about 13 degrees Fahrenheit -- in the relatively short geological span of about 10,000 years.

Many of the findings come from studies of core samples drilled from the deep seafloor over the past two decades. When oceanographers study these samples, they can see changes in the carbon cycle during the PETM.

%26quot;You go along a core and everything's the same, the same, the same, and then suddenly you pass this time line and the carbon chemistry is completely different,%26quot; Dickens said. %26quot;This has been documented time and again at sites all over the world.%26quot;

Based on findings related to oceanic acidity levels during the PETM and on calculations about the cycling of carbon among the oceans, air, plants and soil, Dickens and co-authors Richard Zeebe of the University of Hawaii and James Zachos of the University of California-Santa Cruz determined that the level of carbon dioxide in the atmosphere increased by about 70 percent during the PETM.

That's significant because it does not represent a doubling of atmospheric carbon dioxide. Since the start of the industrial revolution, carbon dioxide levels are believed to have risen by about one-third, largely due to the burning of fossil fuels. If present rates of fossil-fuel consumption continue, the doubling of carbon dioxide from fossil fuels will occur sometime within the next century or two.

Doubling of atmospheric carbon dioxide is an oft-talked-about threshold, and today's climate models include accepted values for the climate's sensitivity to doubling. Using these accepted values and the PETM carbon data, the researchers found that the models could only explain about half of the warming that Earth experienced 55 million years ago.

The conclusion, Dickens said, is that something other than carbon dioxide caused much of the heating during the PETM. %26quot;Some feedback loop or other processes that aren't accounted for in these models -- the same ones used by the IPCC for current best estimates of 21st Century warming -- caused a substantial portion of the warming that occurred during the PETM.Large scale global study shows a massive 50% gap in man made CO2 global warming theory!?
According to your cut and paste we may be in real trouble due to feedbacks and tipping points.

If you think that the temperature rise 55 million years ago was significant, notice that it said %26quot;Average temperatures worldwide rose by about 7 degrees Celsius -- about 13 degrees Fahrenheit -- in the relatively short geological span of about 10,000 years%26quot;. If the earth warmed then at the rate it is rising today and that rise continued for 10 k years, the average temperature increase would not have reached 7 degrees Celsius but rather 74 degrees Celsius.

In comparison, the rise we have seen over the past one hundred years is happening at about one hundred times faster than the rise between the Palaeocene and the Eocene and we have yet to see any of the expected tipping points.

Edit: Perhaps it would help if you read the source document. If you have the capacity to understand it, of course.

http://www.es.ucsc.edu/~jzachos/pubs/Zee

Edit: %26quot;Did you read it%26quot;

Yes and I also read the source documents.

%26quot;If the temperature reconstructions are correct, then feedbacks and/or forcings other than atmospheric CO2 caused a major portion of the PETM warming.%26quot;

Meaning the temperature rise cannot be explained simply by changes in radiative forcings caused by changes of with of CO2 in the atmosphere and indeed other feedbacks and forcings must have come into play. In short what the paper is telling us is if we don't get the feedbacks correct and act on our quickly changing climate we could find ourselves very surprised and quickly screwed.

We simply can't look back fifty five million years to determine our future climate. Due to factors such as plate tectonics, much has changed and we simply are unable to rely on uniformitarianism to give us the right answers.

If you actually read it, you obviously didn't understand it.Large scale global study shows a massive 50% gap in man made CO2 global warming theory!?
So... that means anthropogenic global warming could be twice as bad as the models are currently telling us, yes?Large scale global study shows a massive 50% gap in man made CO2 global warming theory!?
it is not a theory here are my facts

The warming of Earth's surface and oceans over the past century is very well documented, and climate research shows that most of the warming in the past half century results from manmade greenhouse gases.

Snow-mantled crags frame the severe beauty of Queen Maud Land in central Antarctica. Discovered in 1820, the region is known for its jagged peaks with forbidding names like the Jaw of Fenris and The Razor.

In recent years, global warming has been the subject of a great deal of political controversy. As scientific knowledge has grown, this debate is moving away from whether humans are causing warming and toward questions of how best to respond.

Signs that the earth is warming are recorded all over the globe. The easiest way to see increasing temperatures is through the thermometer records kept over the past century and a half. Around the world, the earth's average temperature has risen more than 1 degree Fahrenheit (0.8 degrees Celsius) over the last century, and about twice that in parts of the Arctic.

This doesn檛 mean that temperatures haven't fluctuated among regions of the globe or between seasons and times of day. But if you average out the temperature all over the world over the course of a year, you see that temperatures have been creeping upward.

Although we can't look at thermometers going back thousands of years, we do have some records that help us figure out what temperatures and concentrations were like in the distant past. For example, trees store information about the climate in the place where they live. Each year, trees grow thicker and form new rings. In warmer and wetter years, the rings are thicker. Old trees and wood can tell us about conditions hundreds or even several thousands of years ago.

Keys to the past are also buried under lakes and oceans. Pollen, creatures and particles fall to the bottom of oceans and lakes each year, forming sediments. Sediments preserve all these bits and pieces, which contain a wealth of information about what was in the air and water when they fell. Scientists reveal this record by inserting hollow tubes into the mud to collect sediment layers going back millions of years.

For a direct look at the atmosphere of the past, scientists drill cores through the earth's polar ice sheets. Tiny bubbles trapped in the gas are actually pieces of the earth's past atmosphere, frozen in time. That's how we know that the concentrations of greenhouse gases since the industrial revolution are higher than they've been for hundreds of thousands of years.

Computer models help scientists to understand the Earth's climate, or long-term weather patterns. Models also allow scientists to make predictions about the future climate. Basically, models simulate how the atmosphere and oceans absorb energy from the sun and transport it around the globe. Factors that affect the amount of the sun's energy reaching Earth's surface are what drive the climate in these models, as in real life. These include things like greenhouse gases, particles in the atmosphere (such as from volcanoes), and changes in energy coming from the sun itself.

As usual the orthodox scientific community is putting the cart before the horse! Here are some interesting starting points for your own personal investigation

.

Henrik Svensmark (born 1958) is a physicist at the Danish National Space Center in Copenhagen who studies the effects of cosmic rays on cloud formation. His work presents hypotheses about solar activity as an indirect cause of global warming; his research has suggested a possible link through the interaction of the solar wind and cosmic rays. His conclusions have been controversial as the prevailing scientific opinion on climate change considers solar activity unlikely to be a major contributor to recent warming, though it is thought to be the primary driver of many earlier changes in climate.

In review, the Sun used to be the cause, before the industrial age, but it isn't anymore?

I guess that would make sense if it was the Suns warming effect being blocked by the .038% CO2 we have in our atmosphere. But this is not the case. The Solar winds redirect the Radiation effectively disallowing them to interact with the Oceans, and create cloud cover. We know that a warmer ocean releases CO2, and a cooler Ocean absorbs it. However water takes much longer to change temperature than air, so their is a lagging in the data, that you can see, even in the warmists data. CO2 follows water temp. and water temp lags behind Solar activity. So the Solar activity of the last hundred years has warmed the Oceans, and the Solar minimum in just the last 9 years has not been able to cool the oceans enough yet. Too many people want to study the weather on an hour to hour basis when it is a long term equation!How can we set any carbon policies when the Global Warming Scientists%26039; Best CO2 Predictions are still wrong?
The study you quote is suggesting that based on the PETM, current climate models are *underestimating* the amount that the planet will warm in response to a CO2 increase. This is in fact a very good reason why we should regulate carbon as soon as possible.

*edit* you're talking about a climate change that happened 50 million years ago and saying %26quot;if we don't know exactly what caused every degree of that change, how can we regulate carbon?%26quot;.

You're essentially arguing that until we know everything about everything we shouldn't act on what we do know.

What the PETM showed us is that feedbacks can cause major additional warming, which is exactly what we're worried about with AGW. You're giving us an excellent argument to act ASAP to regulate carbon emissions.How can we set any carbon policies when the Global Warming Scientists%26039; Best CO2 Predictions are still wrong?
It's all bollox.How can we set any carbon policies when the Global Warming Scientists%26039; Best CO2 Predictions are still wrong?
Never argue from the specific to the general, or the general to the specific.

1. They don't know how much sensitivity the climate has to CO2

2. They know that global warming is occurring.

3. They know that a 40% increase of CO2 is the primary initial driver of these changes.

4. They know that most of the CO2 increase has come either from the combustion of fossil fuels, or a lack of absorption caused by deforestation.

The answer is that, they know that CO2 is the cause today. But they aren't sure about what drove the climate to go against its cycles in the past. Like I said, don't argue from the general to the specific or the specific to the general if you can help it.

How did you choose your wedding colours?

I am having such a hard time deciding. Every time I think I have a palette I like I change my mind, or decide it may not work. I'm getting married in June 2010 but in order to shop for anything I need to pick colours.

I've been between turquoise and chocolate, royal purple and butter yellow, emerald green and black, navy and silver - Maybe I'm being fickle or maybe I'm just worried about getting it right.

How did you decide on your colours? Do you have any suggestions from me? I'm quite lost in colours right now.

Please note: I hate pink, we're having a relatively traditional church wedding and are holding our reception in a very nice hall in our hometown. It's quite warm where we're from in June usually in the mid 20s (in Celsius) so probably around 78 Fahrenheit. My bridesmaids are all fair skinned.

Thanks!How did you choose your wedding colours?
I couldn't decide my colors either. So, after choosing my dress, I made an appointment to bring all of my bridesmaids to pick what they'd wear. I basically let them choose with my input. We ended up with light blue. (Most of my bridesmaids are also very pale and blue looks good on all of them) Because there are not many naturally blue flowers (and there are NO flowers near the right shade of blue), I decided to bring in a few pink accents and have pink flowers.How did you choose your wedding colours?
my sorority colors. crimson and cream.

chocolate sounds nice thoughHow did you choose your wedding colours?
The colors I chose for our wedding was purple and white.

You can choose from a spectrum of colors that are in the purple family.

White or cream will be the contrasting color.How did you choose your wedding colours?
My entire wedding plan started with one thing I loved which was fuchsia orchids. From there it went tropical, had to be outdoors,etc. You know you hate pink so you must know what color you gravitate to more than others. Think of it like you just bought a new home. What look would you want? Modern, Asian, bamboo, Country, bunches of yellow daisies or bold %26amp; dramatic flowers? You need to get your overall vibe down before picking colors. You pretty much through out a ton of color choices that have nothing to do with one another.How did you choose your wedding colours?
Yep, you best get started, it usually takes a good year to get everything done for a nice wedding and reception. If it helps any, this is what my daughter did...smile. She was set on red, white and blue of all things...grin. So, she did her reception hall in red, white and blue, wore the traditional white wedding dress and underneath that wedding dress...you wouldn't believe it, but she wore a pair of her fav sneakers and some red, white and blue socks...lol. That's my girl!!! I saw the video, and my daughter was beautiful and the wedding went wonderfully, as well as the reception, with the exception of the groomsmen putting baby powder in the AC in the getaway car...Lordy!

It's YOUR wedding...if you like all the colors and can't decide on one color scheme, perhaps you can have someone help you coordinate all of them into the wedding and the reception. Maybe the parties in your wedding could wear one color scheme and the MIL's could wear another of the color scheme and then your reception could be another, as well as your flowers for the wedding...Don't be so worried about getting it RIGHT, have fun with it...smile. It's a day you will remember forever and something always goes wrong anyway...giggle, whether someone forgets part of their vow, someone steps on your veil, drops the ring pillow, etc....smile. Have fun, God bless and I'm sure all will work out fine. And, that's my 2 cents worth...Bren In TexasHow did you choose your wedding colours?
I know I was just %26quot;dazed%26quot; for awhile then started to relax a little and was able to move forward. I think if you go to wedding sites like www.theweddingknot.com that you will get good info on the latest colors and what is in. %26quot;Green%26quot; themes are really the thing right now. Once you find the combo you LOVE-you will know it and go with it.How did you choose your wedding colours?
i asked myself what my favorite color was and when from there. I picked different shades of blues and one printed dress that is a combo of all the shades of blues i picked. I wanted to make sure the girls dresses looked bright and spring like in the pictures more than anything!How did you choose your wedding colours?
i grew up wanting navy blue, silver and ivory.....i was hoping for a winter wedding....

but a few nights after my engagement i had a dream and i was wearing this red, orange, and ivory dress

i thought it was a beautiful combo

and that's how i picked my colors...

but try pulling colors from the reception hall..

it'll help enhance the colors of the wedding and allow the ceremony and reception have a cohesive look to itHow did you choose your wedding colours?
This might sound weird...but, when i was helping my friend, I went to a Walmart. Grabbed as many of those paint color samples as i could- since they're free there's no cap on how many you can take. Take them all home, throw them on the table invite a friend the compare and pick the perfect assortment of colors.

You can also just choose something that incorporates more than just the 2 or 3 colors folks are used to. Do something like a spring bouquet that has a million different colors throughoutHow did you choose your wedding colours?
my colors were decided by the season i was getting married. i am getting married this december 12th and well thats right around Christmas so i made mine a Christmas themed wedding.

so naturally my colors were Christmas colors. beautiful crimsons, greens, golds and silvers. can also be taken as Gryffindor or Slytherin if you really look at it.How did you choose your wedding colours?
whenever i have mine and my boyfriend decides to propose (i know its coming soon lol) i want gerbera daisy as my pallete they are beautiful and very colorful kinda to match my personality

http://image50.webshots.com/650/8/42/29/

and have black as my background color sort of

http://4.bp.blogspot.com/_RFSoNTm4aeU/SC

but i think that any of those would be great!

but also have you though of combining?

the purple, yellow, navy, and silver would go nicely together but if you want to stick with just two colors i like purple and yellow best

you could go for somr sunflowers like this and tie them with the purple ribbon

and this cake

http://www.bigdaysmallworld.com/dynamic/How did you choose your wedding colours?
i always liked purple and silver. a deep purple not a light purple.How did you choose your wedding colours?
Well first of all, I LOVE ALL YOUR COMBOS!! My wedding was this past Valentine's Day, so we knew we wanted V-Day colors. But instead of going with traditional Red %26amp; White, I chose a deep Crimson Red and Cream and our accent color was Silver. I loved the way everything came out. It sounds like either way, you like Jewel Tones (Emerald, Turquoise, Navy %26amp; Royal Purple). Not to overwhelm you, but what about ALL of those? When I think of those colors, I think of Peacock feathers. You could have the feathers in your centerpieces and even as the boutonnieres. Here are some pics...

Just an idea. I hope I helped. If you have time, let me know what you think. E-Mail me at : MrsHWeddings@hotmail.comHow did you choose your wedding colours?
i chose my favorite colors for the ceremony, orange and yellow. for the reception i chose to do a spring theme because we are getting married in april and we both love spring, but i hate pastel colors. so i am doing bright colors like turquoise, fuscia, purple, bright yellow, orange, lime green ect...

what is your favorite color? and you could pick a theme for your wedding.. thats always fun.How did you choose your wedding colours?
Mine started with Tiger Lillies. Where I live they grow wild along the highways. I started with orange, and then chose a shade that all three of my bridesmaids looked good in.

http://i126.photobucket.com/albums/p117/How did you choose your wedding colours?
Why don't you go out and start looking for dresses. I found it was really hard to match what I was thinking with what was actually available in the stores. Instead of bronze I ended up with gold. Having the girls try on the colors is also a good idea. The other thing is looking at the venue. In my venue the colors were green and gold- white and navy certainly wouldn't have coordinated. Its a summer wedding so don't be afraid of color. I'm currently in love with the peacock color palatte- purple, green and bronze.How did you choose your wedding colours?
I chose fern green, chocolate, burnt orange and merlot. The idea came from my venue and theme. I wanted a wine country rustic theme because we are getting married in a vineyard, so thoes colors went perfectly! I guess you just have to choose colors that you like and that appeal to you. You'll get it you have time.

Is it possible i have toxic shock syndrome?

Symptoms

vomiting, high fever (temperature at least 102掳 Fahrenheit [38.8掳 Celsius]), a rapid drop in blood pressure (with lightheadedness or fainting), watery diarrhea, headache, sore throat, and muscle aches.

Other symptoms may include: confusion or other mental changes; decreased urination; fatigue and weakness; thirst; weak and rapid pulse; pale, cool, moist skin; and rapid breathing.

I檝e had the lighheadednes, almost fainting, headache, watery diarrhea, fatigue and weakness, thirst, pale, cool moist skin and rapid breathing. Now the only other thing is I have a heart disease, Long QT and when I get scared it can also mess me up?And I got extremely scared/nervous earlier yesterday to the point where I almost passed outow I檓 not sure if this could also be affecting the way I檓 feeling? But yesterday was when the lightheadedness and almost fainting was really bad. Now I檓 just tired, have watery direarea, I檓 thirsty and have pale cool skin. Do you think its possible I have the toxic shock syndrome? I did lose track at one point how long I had a tampon in although I thought it was 8 hours.Is it possible i have toxic shock syndrome?
it is possible but it could also be something else. I'm not a doctor, but I watch a lot of House haha.. and I say you really need to go to the hospital.. it could be something dangerous SERIOUSLY GO TO THE HOSPITAL!!

11.2 State of the Atmosphere

Temperature Versus Heat

Temperature- a measurement of how rapidly or slowly

Heat- the transfer of energy that occurs because of a difference in temperature between substances

The direction of heat flow depends on temperature.

Heat is the transfer of energy that fuels atmospheric processes, while temperature is used to measure and interpret that energy.

Measuring Temperature

Can be measured in Fahrenheit(F) or Celsius(C).

The Kelvin scale measures the number above zero, which corresponds to approximately -273degrees C and -523degrees F. This scale is a more direct measure of molecular activity, because at absolute zero, molecular motion theoretically stops.

Dew Point

Dew point- is the temperature to which air must be cooled at constant pressure to reach saturation.

Saturation is the point at which the air holds as much water vapor as it possibly can.

Condensation- when matter changes state from a gas to a liquid

Vertical Temperature Changes

Dry adiabatic lapse rate- the rate at which unsaturated air to which no heat is added or removed will cool.

Lifted condensation level- the height at which condensation occurs

Air Pressure and Density

Atmospheric pressure decreases with height because there are fewer and fewer gas particles exerting pressure.

The density of air is proportional to the number of particles of air occupying a particular space.

Pressure-Temperature-Density Relationship

Pressure increases or decreases, so does temperature. Temperature increases or decreases, so does pressure.

Temperature increases, density decreases. Density increases, temperature decreases.

Temperature Inversions

Temperature Inversion-is an increase in temperature with height in an atmospheric layer.

The Temperature-altitude relationship is inverted or turned upside down.

Wind

Cool air, being more dense, sinks and forces warm, less dense air upward. In the lower atmosphere, air generally moves from areas of high density to areas of low density. The air moves in response to density imbalances created by the unequal heating and cooling of Earth檚 surface. These imbalances create areas of high and low pressure.

Near earth檚 surfaces, wind is disrupted by the friction that results from its contact with trees (etc). Father up, there is nothing to disturb the wind and there is less friction, increasing wind speeds.

Relative Humidity

Humidity- the amount of water vapor in the air

Relative Humidity- the ratio of water vapor in a volume of air relative to how much water vapor that volume of air is capable of holding

RH is expressed in percentage. If a certain volume of air is holding as much water vapor as it possibly can, its RH is 100%.Doing notes?
Well, if you are doing notes off of this (which is entirely correct I might add), then you might as well write it in your own words. However, if these are your notes, then I will state that you take good notes.

National academy of sciences says global warming is caused by human activity. what lie now?

Date: June 6, 2001

FOR IMMEDIATE RELEASE

Leading Climate Scientists Advise White House on Global Warming

WASHINGTON -- In a report requested by the Bush administration, a committee of the National Academies' National Research Council summed up science's current understanding of global climate change by characterizing the global warming trend over the last 100 years, and examining what may be in store for the 21st century and the extent to which warming may be attributable to human activity. The committee -- made up of 11 of the nation's top climate scientists, including seven members of the National Academy of Sciences, one of whom is a Nobel-Prize winner -- also emphasized that much more systematic research is needed to reduce current uncertainties in climate-change science.

%26quot;We know that greenhouse gases are accumulating in Earth's atmosphere, causing surface temperatures to rise,%26quot; said committee chair Ralph Cicerone, chancellor, University of California at Irvine. %26quot;We don't know precisely how much of this rise to date is from human activities, but based on physical principles and highly sophisticated computer models, we expect the warming to continue because of greenhouse gas emissions.%26quot;

Based on assumptions that emissions of greenhouse gases will accelerate and conservative assumptions about how the climate will react to that, computer models suggest that average global surface temperatures will rise between 2.5 and 10.4 degrees Fahrenheit (1.4 and 5.8 degrees Celsius) by the end of this century.

With regard to the basic question of whether climate change is occurring, the report notes that measurements show that temperatures at the Earth's surface rose by about 1 degree Fahrenheit (about .6 degrees Celsius) during the 20th century. This warming process has intensified in the past 20 years, accompanied by retreating glaciers, thinning arctic ice, rising sea levels, lengthening of the growing season in many areas, and earlier arrival of migratory birds.

The committee said the conclusion of the Intergovernmental Panel on Climate Change (IPCC) that the global warming that has occurred in the last 50 years is likely the result of increases in greenhouse gases accurately reflects the current thinking of the scientific community. However, it also cautioned that uncertainties about this conclusion remain because of the level of natural variability inherent in the climate on time scales from decades to centuries, the questionable ability of models to simulate natural variability on such long time scales, and the degree of confidence that can be placed on estimates of temperatures going back thousands of years based on evidence from tree rings or ice cores.National academy of sciences says global warming is caused by human activity. what lie now?
Caused by? They have just completely lost all credibility if they stated it this way. If they want to argue %26quot;enhanced by%26quot; then even though I think they're wrong i would be willing to listen to the argument........National academy of sciences says global warming is caused by human activity. what lie now?
My globes are very warm today, it is 96 degrees!~!National academy of sciences says global warming is caused by human activity. what lie now?
I am an advocate for saving our planet, but we will not convince anyone to change based on information almost 7 years old. I commend your efforts though.National academy of sciences says global warming is caused by human activity. what lie now?
Well, the press release you just quoted is from 2001. It's hardly breaking news, is it? But I agree. Every single academic and scientific institution on the planet currently endorses the IPCC's position on climate change. So if global warming theory is all a conspiracy, it's quite the biggest and most complex in all of human history. In fact, it's completely ridiculous to think a conspiracy of this size could even exist.

Even so though, the overwhelming consensus in the scientific community on the matter doesn't actually prove anything. You'll have an easier time convincing people that anthropogenic climate change is real if you simply present the science to them. Faced with the mind boggling amount of evidence supporting the theory, most people would be hard pressed to deny it.National academy of sciences says global warming is caused by human activity. what lie now?
Then I guess you folks are screwed, cause I refuse to change my lifestyle.

New Antarctic Ice Core To Provide Clearest Climate Record Yet

science daily (Feb 27, 2008) ?After enduring months on the coldest, driest, and windiest continent on Earth, researchers today closed out the inaugural season on an unprecedented, multi-year effort to retrieve the most detailed record of greenhouse gases in Earth's atmosphere over the last 100,000 years.

Working as part of the National Science Foundation's West Antarctic Ice Sheet Divide (WAIS Divide) Ice Core Project, a team of scientists, engineers, technicians, and students from multiple U.S. institutions have recovered a 580-meter (1,900-foot) ice core -- the first section of what is hoped to be a 3,465-meter (11,360-foot) column of ice detailing 100,000 years of Earth's climate history, including a precise year-by-year record of the last 40,000 years.

The dust, chemicals, and air trapped in the two-mile-long ice core will provide critical information for scientists working to predict the extent to which human activity will alter Earth's climate, according to the chief scientist for the project, Kendrick Taylor of the Desert Research Institute of the Nevada System of Higher Education. DRI, along with the University of New Hampshire, operates the Science Coordination Office for the WAIS Divide Project.

WAIS Divide, named for the high-elevation region that is the boundary separating opposing flow directions on the ice sheet, is the best spot on the planet to recover ancient ice containing trapped air bubbles -- samples of the Earth's atmosphere from the present to as far back as 100,000 years ago.

While other ice cores have been used to develop longer records of Earth's atmosphere, the record from WAIS Divide will allow a more detailed study of the interaction of previous increases in greenhouse gases and climate change. This information will improve computer models that are used to predict how the current unprecedented high levels of greenhouse gases in the atmosphere caused by human activity will influence future climate.

The WAIS Divide core is also the Southern Hemisphere equivalent of a series of ice cores drilled in Greenland beginning in 1989, and it will provide the best opportunity for scientists to determine if global-scale climate changes that occurred before human activity started to influence climate were initiated in the Arctic, the tropics, or Antarctica.

The new core will also allow investigations of biological material in deep ice, which will yield information about biochemically processes that control and are controlled by climate, as well as lead to fundamental insights about life on Earth.

Says Taylor, %26quot;We are very excited to work with ancient ice that fell as snow as long as 100,000 years ago. We read the ice like other people might read a stack of old weather reports.%26quot;

The WAIS project took more than 15 years of planning and preparation, including extensive airborne reconnaissance and ground-based geophysical research, to pinpoint the one-square-kilometer (less than a square mile) space on the 932,000-square-kilometer (360,000-square-mile) ice sheet that scientists believe will provide the clearest climate record for the last 100,000 years.

With only some 40 days a year when the weather is warm enough for drilling -- yesterday's temperature was a balmy -15 degrees Celsius (5 degrees Fahrenheit) -- it is expected to take until January 2010 to complete the fieldwork.

For the project, Ice Coring and Drilling Services of the University of Wisconsin-Madison built and is operating a state-of-the-art, deep ice-coring drill, which is more like a piece of scientific equipment than a conventional rock drill used in petroleum exploration. The U.S. Geological Survey National Ice Core Laboratory in Denver designed the core handling system. Raytheon Polar Services Corporation provides the logistical support. The NSF Office of Polar Programs-U.S. Antarctic Program funds the project. The core will be archived at the National Ice Core Laboratory, which is run by the USGS with funding from NSF.How does this events apply to the natural world?Why is this infomation important for us to know and how would?

The WAIS Divide core is also the Southern Hemisphere equivalent of a series of ice cores drilled in Greenland beginning in 1989, and it will provide the best opportunity for scientists to determine if global-scale climate changes that occurred before human activity started to influence climate were initiated in the Arctic, the tropics, or Antarctica.

The new core will also allow investigations of biological material in deep ice, which will yield information about biogeochemical processes that control and are controlled by climate, as well as lead to fundamental insights about life on Earth.

Says Taylor, %26quot;We are very excited to work with ancient ice that fell as snow as long as 100,000 years ago. We read the ice like other people might read a stack of old weather reports.%26quot;

The WAIS project took more than 15 years of planning and preparation, including extensive airborne reconnaissance and ground-based geophysical research, to pinpoint the one-square-kilometer (less than a square mile) space on the 932,000-square-kilometer (360,000-square-mile) ice sheet that scientists believe will provide the clearest climate record for the last 100,000 years.

With only some 40 days a year when the weather is warm enough for drilling -- yesterday's temperature was a balmy -15 degrees Celsius (5 degrees Fahrenheit) -- it is expected to take until January 2010 to complete the fieldwork.

For the project, Ice Coring and Drilling Services of the University of Wisconsin-Madison built and is operating a state-of-the-art, deep ice-coring drill, which is more like a piece of scientific equipment than a conventional rock drill used in petroleum exploration. The U.S. Geological Survey National Ice Core Laboratory in Denver designed the core handling system. Raytheon Polar Services Corporation provides the logistical support. The NSF Office of Polar Programs-U.S. Antarctic Program funds the project. The core will be archived at the National Ice Core Laboratory, which is run by the USGS with funding from NSF.Why would you choose this artical?And did you agree with the informatin given?
I would choose this article because a friend of mine just got back from doing this in Antarctica. It's very valuable work and I don't think there's much you could disagree with in the article.

How will this information be helpful to you or those around you?

Working as part of the National Science Foundation's West Antarctic Ice Sheet Divide (WAIS Divide) Ice Core Project, a team of scientists, engineers, technicians, and students from multiple U.S. institutions have recovered a 580-meter (1,900-foot) ice core -- the first section of what is hoped to be a 3,465-meter (11,360-foot) column of ice detailing 100,000 years of Earth's climate history, including a precise year-by-year record of the last 40,000 years.

The dust, chemicals, and air trapped in the two-mile-long ice core will provide critical information for scientists working to predict the extent to which human activity will alter Earth's climate, according to the chief scientist for the project, Kendrick Taylor of the Desert Research Institute of the Nevada System of Higher Education. DRI, along with the University of New Hampshire, operates the Science Coordination Office for the WAIS Divide Project.

WAIS Divide, named for the high-elevation region that is the boundary separating opposing flow directions on the ice sheet, is the best spot on the planet to recover ancient ice containing trapped air bubbles -- samples of the Earth's atmosphere from the present to as far back as 100,000 years ago.

While other ice cores have been used to develop longer records of Earth's atmosphere, the record from WAIS Divide will allow a more detailed study of the interaction of previous increases in greenhouse gases and climate change.

Not very much. Ice core data is very speculative and includes a lot of assumptions. Another good idea for scientists to predict future climate change and keep them employed in a job. This is a classic example. The worse the predictions the more money they will pour into the project. More money for the scientists who would other wise not have a job. I wish I was on a project like this. Free money for guessing past climates.How will this information be helpful to you or those around you?
It will help with understanding possible drivers behind global warming. I might add though, that 'unprecedented' is not a word I would apply to the current levels of CO2 - I suspect the Earth has had higher levels of CO2 in the distant path - certainly in historical times, the levels are much higher than in the past, but the Earth has had similarly high levels of carbon dioxide in its past...

1.All nonzero digits are significant. Thus, 8.15 cm, 0.723 cm, 52.3 cm, and 0.000234 cm all contain three significant figures.

Zeros between nonzero digits are significant. There are three significant figures in each of the measurements, 101 cm, 10.5 cm and 1.06 cm.

Terminal zeros to the right of the decimal point are significant. There are three significant figures in 0.100 cm, 0.110 cm, and 1.00 cm.

Zeros preceding the first nonzero digit are not significant. There are three significant figures in 0.0101 cm, 0.00100 cm and 0.000101 cm.

Terminal zeros in a number without an explicit decimal point may or may not be significant. When a measurement is given as 200 cm, you do not know whether one, two, or three significant figures were intended. Any uncertainty can be removed by expressing the number in scientific notation.

THANK YOU SO MUCH! :)Physics assignment! please help!?
The conversion of fahrenheit to celsius is

C=(F-32)/1.8

So 864=462.22

and -360=-217.78

Celsius to Kelvin formula is

K=C + 273

Hope this helps you figure some of them out. Just google your question and it may help you more than this site.
