Climate Science


Climate change is an increase in the average temperatures in the atmosphere and oceans over time due primarily to human influences. Although heat-trapping pollution, such as carbon dioxide and methane, (also known as “greenhouse gases” (GHGs) are naturally occurring elements, humans have greatly increased the amount of this pollution in our atmosphere through the burning of fossil fuels. climate_change_greenhouse.jpgClimate pollution acts as a blanket around the earth, keeping it warm at night. Too much pollution is like adding layer after layer of blankets — eventually it gets too hot.

The problem of climate change is so severe that it requires solutions at every level of society – individuals, cities, states, federal government, and international agreements. Every individual can take action to reduce his or her own carbon footprint. Local businesses and elected officials can drive demand for renewable energy and energy efficiency. One of the most important things America can do is pass meaningful climate policy that will set a limit and begin to reduce climate pollution. America must also participate in an international agreement to reduce pollution because global warming is a global problem.
