Summary: | Fossil fuel burning and deforestation over the industrial period have increased the atmospheric concentration of carbon dioxide (CO2) to a level unprecedented in the past hundred thousands of years. In conjunction with human-made emissions of other greenhouse gases, this has caused an increased trapping of longwave radiation in the atmosphere (anthropogenic greenhouse effect). This energy imbalance has caused global warming, although most of the excess heat has been absorbed by the ocean and some also by the cryosphere (ice and snow). Consequently, the thermal expansion of the ocean and the melting of ice sheets and glaciers have caused sea-level rise. CO2 emissions also cause ocean acidification and further impacts on the Earth System. Knowledge of these past changes is based on independent evidence from direct observations and climate archives such as tree rings and ice cores. However, global CO2 emissions have rapidly increased during the recent decades; and even if we were able to suddenly stop ... |
