Tierr@_de_N@die: For the climate change denial groups: First fact, global average temperature is directly related with atmospheric CO2 levels. Second fact, we beat again the historic record since the last glacial cycle, some thousands of years ago... If you don't understand it is quite clear because you are still a denier.
Carbon dioxide (CO2) is an important heat-trapping (greenhouse) gas, which is released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions. The first graph shows atmospheric CO2 levels measured at Mauna Loa Observatory, Hawaii, in recent years, with average seasonal cycle removed. The second graph shows CO2 levels during the last three glacial cycles, as reconstructed from ice cores.
