Global Warming

1. It is true that ancient glaciers show that there is a connection between C02 and warming, but it is the opposite of what you say here. The studies show that as temperature rises, C02 levels rise--around 1000 years after the temperature rises:

"As temperature rises, CO2 also rises but lags the warming by 800 to 1000 years (Monnin 2001, Caillon 2003, Stott 2007).How does warming cause a rise in atmospheric CO2? As the oceans warm, the solubility of CO2 in water falls (Martin 2005). This causes the oceans to give up more CO2, emitting it into the atmosphere. The exact mechanism of how the deep ocean gives up its CO2 is not fully understood but believed to be related to vertical ocean mixing (Toggweiler 1999)." ("CO2 lags temperature - what does it mean?")

2. Sea levels are not rising. According to Swedish geologist and physicist Nils-Axel Mörner, formerly chairman of the INQUA International Commission on Sea Level Change, "the sea is not rising. It hasn't risen in 50 years." (Rise of sea levels is 'the greatest lie ever told')

3. A rise in temperature is not melting the ice caps. Ice at the North Pole is decreasing and ice at the South Pole is decreasing. Overall, ice is remaining the same: "In 2007 2008, two very different records were set. The Arctic broke the previous record for the least sea ice area ever recorded, while the Antarctic broke the record for the most sea ice area ever recorded. Summed up over the entire earth, polar ice has remained constant..... There has been no net gain or loss of polar sea ice since records began." (Are the ice caps melting?)

4. “NASA stated today that it was wrong when it release a report that 1998 was the warmest year ever recorded in modern history…. According to H. Sterling Burnett, a senior fellow at the National Center for Policy Analysis … James Hansen's well-known claims that 1998 was measured as the warmest year on record in the U.S. were the result of a serious mathematical error. NASA has now corrected that error, and 1934 is now known as the warmest year on record, with 1921 the third warmest year instead of 2006 as was also previously claimed. Moreover, NASA now also has to admit that three of the five warmest years on record occurred before 1940-it has up until now held that all five of them occurred after 1980.” ("NASA Admits that 1934, Not 1998, was the Warmest Year on Record ")

5. This website suggests that at least some of the temperature increases may be due to where the thermometers are being placed--such as right next to incinerators.

6. “For nearly a decade now, there has been no global warming. Even though atmospheric carbon dioxide continues to accumulate - it's up about 4 percent since 1998 - the global mean temperature has remained flat. That raises some obvious questions about the theory that CO2 is the cause of climate change.”

7. Some scientists do not believe in human-caused global warming. Richard Lindzen, Alfred P. Sloan Professor of Atmospheric Science at MIT, is one example.
