Includes natural changes (cyclic variability, volcanic eruptions, solar output) and human-caused changes (due to GHG emissions and land use changes)
Climate Change 2014: Synthesis Report
November 3, 2014
This new Synthesis Report from the IPCC summarizes the contents of 5 studies released over the past year. These studies confirm that climate change caused by human activities is having impacts on ecosystems and human well-being across the U.S. and around the world.
This course explores the science of climate change. Students will learn how the climate system works; what factors cause climate to change across different time scales and how those factors interact; how climate has changed in the past; how scientists use models, observations and theory to make predictions about future climate; and the possible consequences of climate change for our planet.
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.
