Sun radiates energy through atmosphere heating the surface
Surface absorbs solar energy releases it back to atmosphere as IR radiation; some of goes back into space
Some of IR radiation absorbed by greenhouse gases re-emit energy as heat back toward surface
Thus, the Greenhouse Effect prevents Earth from losing heat Without the greenhouse effect, the surface of the Earth would be about 60 Fahrenheit degrees cooler, making almost impossible for life to sustain itself
International treaty proposed to United Nations Framework Convention on Climate Change
Intended to achieve “stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system”
Legally forces for reduction of carbon dioxide, methane, nitrous oxide, sulphur hexafluoride and gases hydrofluorocarbons and perfluorocarbons produced by industrialized nations
Industrialized countries will agree to reduce their collective greenhouse gas emissions by 5.2% compared to the year 1990 (for the U.S., national limitations range from 7% reduction)
U.S. has yet ratified nor withdrawn from the Protocol - Kyoto Protocol is nonbinding on the U.S. unless ratified; President Obama has not yet taken any action with the senate that would change the U.S.’s position towards the protocol.
The America’s Climate Security Act of 2007 , commonly referred to as the Cap and Trade Bill , was proposed in U.S.
Bill was proposed for greater U.S. alignment similar to Kyoto standards and goals and provides for establishment of a federal bureau of Carbon Trading, Regulation, and Enforcement
