Document Summary
Geog 1070: contemporary environmental issues reading notes chapter 20. The rate of sea level increase is 3 cm/decade. Un organized the intergovernmental panel on climate change (ipcc: provides scientific statements about global climate change, 2014 stated that human produced air pollutants have caused most of the climate observed over the last 50 yrs. Carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons, tropospheric ozone accumulate in the atmosphere due to human activities: all are greenhouses gases that absorb radiation from the sun increasing temp of the atmosphere. Burning of vegetation releases co2 and it reduces the aptity for the biosphere to remove and store carbon in roots and tree trunks through photosynthesis. Gases absorb infrared radiation so the higher greenhouse gas leads to warming and global climate change. Radiative forcing capacity of gases to affect the balance of energy entering and leaving he atmosphere. Co2 accounts for 60% of the increased radiative forcing and heat retention caused by greenhouse gases.
