Global Warming and Mitigation

Earth’s climate has experienced a rise of 0.8°C in global surface temperature during the 20th century caused by increased atmospheric concentration of biogenic gases that contribute to the greenhouse effect. Greenhouse effect occurs by contribution from fossil energy, deforestation and degradation of soils. General circulation models predict rising atmospheric CO2 concentration, resulting in temperature increases from 1.5°C to 5.5°C in the 21st century, and 0.60–1.0m rise in sea level. Impacts include degradation of natural resources, reduced agricultural production and human dislocation. Consider the major contributors of biogenic gases to get the largest impact in selection of mitigation and adaptation methods to climate conditions.
