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 features a short animated sequence that illustrates the difference between young and old carbon released into the atmosphere from the consumption of food (young carbon) and the burning of fossil fuels (old carbon).

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.

Climate Change 2013: The Physical Science Basis

On September 27, 2013, Working Group I of the Intergovernmental Panel on Climate Change (IPCC) presented its report to member governments for approval and acceptance. The report is the first of four that will make up the IPCC's 5th Assessment.

Carbon Dioxide Information Analysis Center (CDIAC)

The CDIAC is the primary global-change data and information analysis center of the U.S. Department of Energy (DOE). It contains information on concentrations of carbon dioxide and other radioactively active gases in the atmosphere; the role of the terrestrial biosphere and the oceans in the biogeochemical cycles of greenhouse gases; emissions of carbon dioxide to the atmosphere; long-term climate trends; the effects of elevated carbon dioxide on vegetation; and the vulnerability of coastal areas to rising sea level.

In this experiment, students will observe two model atmospheres: one with normal atmospheric composition and another with an elevated concentration of carbon dioxide. These two contained atmospheres will be exposed to light energy from a sunny window or from a lamp. The carbon dioxide is produced by a simple reaction and tested using bromothymol blue (BTB).
