Arctic Climate Feedbacks [peer-reviewed]

This peer-reviewed educational video introduces feedbacks that are important in the Arctic climate system. It is aimed at an undergraduate non-science major level. The video was produced by a team of CIRES scientists in collaboration with CIRES Education and Outreach. Video production was funded by Professor Jennifer Kay’s CAREER Award from the National Science Foundation…

NASA Rising Seas: The State of the Greenland Ice Sheet (2015)

Seas around the world have risen an average of nearly 3 inches since 1992, with some locations rising more than 9 inches due to natural variation, according to the latest satellite measurements from NASA and its partners. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of…

Sea level rise of the past 23 years explained

Oceanographer Josh Willis from NASA’s Jet Propulsion Laboratory narrates this video about the causes of sea level rise and how sea level has changed over the last two decades as observed by the Jason series of satellite missions. Source

Climate scientist Piers Sellers on NASA’s satellite observations

The view of Earth from orbit was the focus of this What’s New in Aerospace? presentation televised on NASA Television from the Smithsonian National Air and Space Museum in Washington. The program featured Piers Sellers, a climate scientist and former NASA astronaut, taking viewers on a tour of our home planet as never seen before.…

Royal Society: An introduction to climate change in 60 seconds

Published on Dec 10, 2014: Climate science explained in 60 seconds by the Royal Society and the US National Academy of Sciences. During the last 200 years, human activities such as the burning of fossil fuels have increased concentrations of CO2 in the atmosphere by 40%. If unchecked, continuing emissions will warm up the planet…

Novel climate proxy reveals CO2 content of Earth’s atmosphere, of the past 400 million years

The study New constraints on atmospheric CO2 concentration for the Phanerozoic (DOI: 10.1002/2014GL060457), by Peter J. Franks, Dana L. Royer, David J. Beerling , Peter K. Van de Water, David J. Cantrill, Margaret M. Barbour, and Joseph A. Berry, estimates CO2 in Earth history based on a new climate proxy. Estimates are in particular based…

Hydroxyl Radicals In Our Atmosphere – An Animated Explanation

Stronger Winds Shift Heat to Deeper Pacific

Published on Feb 9, 2014 Heat stored in the western Pacific Ocean caused by an unprecedented strengthening of the equatorial trade winds appears to be largely responsible for the hiatus in surface warming observed over the past 13 years. New research published in the journal Nature Climate Change indicates that the dramatic acceleration in winds…

NASA: Ocean Heat Content

Oceanic heat content (OHC) is the heat stored in the ocean. Oceanography and climatology are the science branches which study ocean heat content. The changes in the ocean heat play an important role in sea level rise, because of thermal expansion. It is with high confidence that Ocean warming accounts for 90% of the energy accumulation from global warming between 1971 and 2010.  …
