Permafrost may release largest Mercury source on Earth

There are 32 million gallons worth of mercury, or the equivalent of 50 Olympic swimming pools, trapped in the permafrost. For context, that’s “twice as much mercury as the rest of all soils, the atmosphere, and oceans combined. And it could be released.

Trump: Record Cold Disproves Global Warming!

CO2 emissions from fossil fuel burning caused the Arctic to warm at least twice as fast as the rest of globe, resulting in the disappearance of Arctic sea ice – which in turn weakens the polar vortex, which in turn favors cold air intrusion into lower latitudes, and vise-versa.

Expert asks, can we control the climate crisis in time?

Stefan Rahmstorf speaks at the 2017 Bonn climate conference, explaining the basics of global climate change, and outlines our current emissions pathway – asking if we can control the climate crisis. The talk is titled Climate Action and Human Wellbeing at a Crossroads: Historical Transformation or Backlash?

Arctic Sea Ice and Permafrost Status Report 2017

The Arctic is warming faster than anywhere else on Earth, affecting people in the region, fish and wildlife they depend on for food, and their environment. This unprecedented change has ramifications far beyond the region for the global economy, weather, climate, sea level, trade and security. Watch the full Arctic Report 2017 AGU press conference…

Most accurate climate models predict greatest future warming

The climate change simulations that best capture current planetary conditions are also the ones that predict the most dire levels of human-driven warming, according to a statistical study released in the journal Nature Wednesday. Greater future global warming inferred from Earth’s recent energy budget Greater future global warming inferred from Earth’s recent energy…

Francis: A Trigger for Rapid Arctic Warming

Jennifer Francis from Rutgers University speaks about our atmosphere with a scope on the Arctic response to climate change and the connection to weather. This video is part of a panel presentation published by Earth Institute November 2017, with already improved sound quality (reduced humming sound).

Arctic Sea Ice Extent 2nd lowest on Record for the Date

Another “warm” and slow freeze season in the #Arctic. Sea ice extent is the 2nd lowest on record for the date (2016 – lowest) & 1.9 million km^2 below the 1980s average…

The 936 PPM CO2 NASA Model Prediction

This NASA visualization is based on the latest IPCC report, and uses the business as usual scenario, where carbon dioxide concentrations rise to 936 parts per million—more than double today’s levels of 400 parts per million—by the year 2100. Temperature anomalies are estimated to be close to 4°C in the Arctic.


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…
