If one looks at these data in finer detail, as shown in Figure 4, it becomes evident that temperature is driving the carbon dioxide concentration, not the other way around.Changes in temperature trends led similar features in carbon dioxide and methane by some 800 years in this analysis.One explanation for this relationship is that warming of the oceans releases carbon dioxide to the atmosphere, increasing its concentration.This is likely due to the fact that the oceans contain much more carbon dioxide than the atmosphere, and they release carbon dioxide at warm temperatures and absorb it at cool temperatures.Arguments against Carbon Dioxide Driving Global Warming In his presentation Al Gore argues that the correlation between earth's average global temperature and the concentration of carbon dioxide in the atmosphere irrefutably demonstrates that carbon dioxide drives global warming.
Conclusions Individual temperature records commonly used by climatologists and paleoclimatologists show that the past 1,000 years have been marked by periodic warm and cold periods, not by a uniform climate trend.
In fact, they normally show a 400-year-long warm period from about 1000 to 1400 A.
D., which is known as the Medieval Optimum in Europe. Certain crops like grapes could no longer be grown, the economy declined, and the Vikings were forced out of Greenland by the encroaching snow and ice.
However, studies over many years have not been able to confirm a convincing physical mechanism between sunspots and weather or climate.
When the temperature trend in the "blade" of the hockey stick between 18 is examined in more detail, as shown in Figure 2, it is found that the average global temperature doesn't increase exponentially like the measurements of carbon dioxide do at Mauna Loa.
Following World War II, industrial productivity and the release of carbon dioxide climbed rapidly.
