What proof do deniers have that Global Warming is not real? Please provide citations.?
@Bojo, common sense is great! But using common facts says the world is flat? Does common sense not say investigate.
@ Bojo: Science is using common sense!
We know that CO2 warms the planet, its proven. We also know that we are pouring millions of tons of CO2 and other gas into the air. And SHOCK the global temperature rises much faster.
Direct observations find that CO2 is rising sharply due to human activity. Satellite measurements find less energy is escaping to space at CO2 absorption wavelengths. Ocean and surface temperature measurements find the planet is steadily accumulating heat. There is direct empirical evidence that human CO2 emissions are causing global warming.
@SAGE, none of ur links work?
@Coldfuse: Schulte's paper (going on DailyTech's account) places great emphasis on the fact that only one paper endorses 'catastrophic climate change'. This is a classic straw man argument. Oreskes' 2004 paper never refers to an imminent catastrophe. Neither do the IPCC nor do the Academies of Science from 11 countries that endorse the consensus position that most of the warming over the last 50 years is likely due to the increase in greenhouse gas concentrations.
Even more fuss is made over the large percentage of neutral studies. Ironically, Oreskes emphasised the same point in 2004 when she published The Scientific Consensus on Climate Change. Nowadays, earth science papers are rarely found explicitly endorsing plate tectonics as the theory is established and taken for granted. The fact that so many studies on climate change don't bother to endorse the consensus position is significant because scientists have largely moved from what's causing global warming onto discussing detai
@Answers: To those who claim CO2 is not a pollutant! While there are ways in which CO2 is a pollutant (acidification of the ocean), it's primary impact is its greenhouse warming effect. While the greenhouse effect is a natural occurance, too much warming has severe negative impacts on agriculture, health and environment.

@J, your source is worng using radiation we have found there is a increase in the amount of CO2.

Some claim that it is not the deniers responsibility to prove global warming not to be occurring. They say the onus is on those who claim global warming to be real to prove it is. To the contrary, it is the deniers who must prove the story that thermometers, satellites, melting alpine glaciers and decreasing arctic/Antarctic ice mass etc. are telling to be flawed. They must explain away a cooling stratosphere and warming troposphere, the increasing heat content of the deep oceans and the measured deepening in the spectral lines of IR absorption by CO2 over the past several decades.
In fact skeptics do attempt to find fault with all these things. Their attempts so far have fallen flat. Their best method is to attack all aspects of science that even remotely support AGW theory. Then they attempt to discredit climate scientists and any organizations they are associated with. Never have they succeeded in demonstrating the basic science in support of AGW to be faulty however, all they seek to do is promote doubt.

From Coldfuse:
"2.The increasing temperature will cause increased water evaporation, which is the cause for the positive feedback needed to reach the high temperatures."
So glad that my theory is becoming accepted: read on.
•It's actually very simple.
Since about the late 1940s people in the west have had access to domestic washing machines, some of the more profligate use tumble driers.
Imagine the trillions of tons of fresh water used by these machines and compare it to the amount that would have been used by laundering using two stones or a washboard. Nobody changed their clothes every day as we do now.
The wet washing is dried either by hanging out or the tumble drier.
Trillion and Trillions of tons of fresh water is thus released into the atmosphere every week, it must fall as rain somewhere. Excess moisture also (as any student of hurricanes knows) changes the way winds blow and air currents circulate around the globe.
•The more the wind blows, the warmer it becomes.
That's the enemy. There's your problem, Mum doing the weekly wash!
QED.

Been thinking about this for years since I found out that hurricanes start as a zephyr off Africa and pick up energy and hence ferocity as they pass over water.

Yes Ben O that is certainly true. When the small warming is less than or more likly much less than the natural variation in climate , you can't say that it will be warmer tomarrow, only that theoretically it should be some fraction warmer than what it would have been which is unknowable unless you are like alarmists and think you see the future.

There are no sources that 'prove' CO2 will cause significant global warming without first assuming that past warming was caused by CO2.
Using first principles of physics, it can be shown that atmospheric CO2 can cause a small amount of warming and there are no studies that demonstrate otherwise.
- ?Lv 61 decade ago
there has been no increase in atmospheric CO2 in over 150 years so how is man produced CO2 increasing the temp? See link-
- JimZLv 71 decade ago
First you have to define global warming. It is a meaningless name. I don't know if you are defining it as any warming or just man caused? It is deliberately vague. First of all climates always vary. That is like 6th grade Earth Science. There was a cool period that ended 300 years ago, the Maunder Minimum. We currently live in the Modern Maximum. If your question is what proof do we have that the earth hasn't warmed it is an incomplete and imprecise question that can't be answered without a time period. It is difficult to prove anything isn't real. You can't prove that warming isn't natural. About the best you can do is suggest that it is difficult to know exactly why it warmed or why it cooled from 1940 to 1970 or cooled from 1400 to 1800 or warmed since. Ignorance, however, is not a theory.

Obviously, you have not done your research. Some of the finest scientists on earth have debunked global warming. But I will provide you with an answer you may not expect. And that is this: anthropogenic global warming has yet to be proved.
Here are six main predictions of the anthropogenic global warming models. Not only can they not be proved, they can be disproved. The link provides a more in-depth look from Dr. Leonard Weinstein.
"1.The average Earth’s temperature will increase at a rate of 0.20C to 0.60C per decade at least to 2100, and will continue to climb after that if the CO2 continues to be produced by human activity at current predicted rates.
2.The increasing temperature will cause increased water evaporation, which is the cause for the positive feedback needed to reach the high temperatures.
3.The temperature at lower latitudes (especially tropical regions) will increase more in the lower Troposphere at moderate altitudes than near the surface.
4.The greatest near surface temperature increases will occur at the higher latitudes.
5.The increasing temperature at higher latitudes will cause significant Antarctic and Greenland ice melt. These combined with ocean expansion due to warming will cause significant ocean rise and flooding.
6.A temperature drop in the lower Stratosphere will accompany the temperature increase near the surface. The shape of the trend down in the Stratosphere should be close to a mirror reflection of the near surface trend up."
Here is Dr. Weinstein's biography so we don't have to hear a bunch of ad hominem attacks:
Leonard Weinstein received a B.Sc. in Physics in 1962 from Florida State University. He started work at NASA Langley Research Center in June 1962. While at Langley, Leonard obtained his Master and Doctor of Science degrees in Engineering from the George Washington University. He continued to work at NASA Langley until June 2007, ending as a Senior Research Scientist. Dr. Weinstein has had a career that is recognized for innovation. He has over 90 publications, including 11 patents. He has received numerous awards, commendations, and recognition's for innovative experimental research, including an Exceptional Engineering Achievement Medal, an IR-100 award, the 1999 American Institute of Aeronautics and Astronautics (AIAA) Engineer of the year, the James Crowder Award, and over 40 other awards and recognitions for innovative experimental research. Dr. Weinstein is presently a Senior Research Fellow at the National Institute of Aerospace.

Global warning might be real. If it is, it is blown way out of proportion, to the point of being a cult of global warming hysteria.

For starters, you as an AGW believer have to prove something exists. Not the other way around.
Show me your evidence that can be used on unknown data and have it fit. There arent any models that can show anything that fits other than didley squat.
Show me otherwise as you are trying to prove CO2 as guilty.
I do have a link for your consensus though for now
