Includes natural changes (cyclic variability, volcanic eruptions, solar output) and human-caused changes (due to GHG emissions and land use changes)
State of the Climate in 2013
July 23, 2014
On July 17, NOAA and the American Meteorological Society released the State of the Climate in 2013 report. A 24-year tradition encompassing the work of 425 authors from 57 countries, the report uses dozens of climate indicators to track patterns, changes, & trends of the global climate system.
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 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 is the first of a three-video series from the Sea Change project. It features the field work of scientists from the US and Australia looking for evidence of sea level rise during the Pliocene era when Earth was (on average) about 2 to 3 degrees Celsius hotter than it is today.
This video features research conducted at University of Colorado's Institute of Arctic and Alpine Research, which studies isotopes of hydrogen trapped in ice cores to understand climate changes in the past.
UN Climate Change Learning Partnership Releases Learning Resources Guides on Climate Change Science
July 10, 2014
The UN Climate Change Learning Partnership released two resource guides to help people understand the science of climate change. The two guides provide a tour of the best & most relevant resources on climate change science.
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.
WMO Releases Annual Status of the Global Climate Report
March 25, 2014
The dramatic impact of climate variability and climate change continued to be felt all over the world throughout 2013.The World Meteorological Organization statement on the status of the global climate in 2013 provides a snapshot of global and regional trends in weather and climate over the past year and highlights some of the year’s most significant extreme events.
