This lesson covers different aspects of the major greenhouse gases - water vapor, carbon dioxide, methane, nitrous oxides and CFCs - including some of the ways in which human activities are affecting the atmospheric concentrations of these key greenhouse gases. This is lesson six in a nine-lesson module about climate change.

In this activity students learn how Earth's energy balance is regulating climate. This activity is lesson 4 in the nine-lesson module Visualizing and Understanding the Science of Climate Change.

Proposed EPA Plan Would Cut Emissions From Power Plants By 30%

On June 2, the EPA announced the Clean Power Plan. Under the Clean Air Act and President Obama's Climate Action Plan, the proposed plan would cut carbon pollution from existing power plants, the largest source of greenhouse gas emissions in the U.S.

Switch to Natural Gas Power Plants Reduces Carbon Dioxide Emissions

Power plants that use natural gas release far less of the greenhouse gas carbon dioxide than coal-fired power plants, according to a new study from CIRES and NOAA scientists.

This short animated video provides a general overview of the role of carbon dioxide in supporting the Greenhouse Effect.

This video highlights the work of climate scientists in the Amazon who research the relationship between deforestation, construction of new dams, and increased amounts of greenhouse gases being exchanged between the biosphere and the atmosphere.

This free webinar will examine how climate change and rising CO2 levels may affect forest carbon storage.
