Climate change mitigation generally involves reductions in … This broad consensus that climate change is happening and is caused primarily by excess greenhouse gases from human activities is based on multiple lines of evidence, from basic physics to the patterns of change through the climate system (including the atmosphere, oceans, land, biosphere, and cryosphere). Climate change is projected to have far-reaching repercussions – including sea level rise inundating cities and shifting weather patterns causing long-term declines in agricultural yields. Does the data validate those who say humans are causing the earth to catastrophically warm? How natural and anthropogenic influences alter global and regional temperatures: 1889 to 2006. Accessed February 26, 2010. How will Earth's surface temperature change in future decades? Based just on the physics of the amount of energy that CO 2 absorbs and emits, a doubling of atmospheric CO 2 concentration from pre-industrial levels (up to about 560 ppm) would by itself cause a global average temperature increase of about 1 °C (1.8 °F). The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified. While incoming sunlight may have increased slightly over the last century, this increase accounts for less than 10 percent of the warming our world experienced over that time. John H.
