In this short video, host Dr. Ryan interviews graduate student Amy Steiker at the Institute of Arctic and Alpine Research about her research, using isotopes of nitrous oxide, connecting human activity to greenhouse gas emissions.

This interactive addresses the question if we can reduce CO2 emissions by 20% of 1990 levels and help avoid dangerous climate change? Users of this interactive can manipulate changes to various sources and uses (supply and demand) of energy with the goal of reducing C02 emissions in Great Britain by 80% in the year 2050.

This visualization is a website with an interactive calculator that allows for estimation of greenhouse gas production from croplands in the United States.

This graphic depicts evidence for a human fingerprint on climate change based on multiple sets of independent observations. The graphic is available to study at three levels - basic, intermediate, and advanced understanding, with substantial support for students to investigate the evidence themselves and draw their own conclusions.

This interactive video series reviews global warming by recognizing the problem, addressing the sources and impacts, and weighing the options. It is a six-chapter series. Experts from different countries weigh in and answer some critical questions, including what countries have resources and the perspectives necessary to reach a consensus on handling the next steps and the economic costs involved.

This video describes what black carbon is, where is comes from, and how it contributes to sea ice melt and global warming.

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.

Cover of the 2014 National Climate Assessment

National Climate Assessment Released

The third National Climate Assessment, released May 6, provides an in-depth look at climate change impacts on the U.S both now and into the future. It details the multitude of ways climate change is already affecting and will increasingly affect the lives of Americans.

Climate Change 2014: Mitigation of Climate Change

On April 15 in Berlin, Germany, the Intergovernmental Panel on Climate Change approved and released Working Group III's Fifth Assessment Report - a comprehensive assessment of all relevant options for mitigating climate change through limiting or preventing greenhouse gas emissions, as well as activities that remove them from the atmosphere.
