Arctic Atmospheric Circulation, Freshwater and Sea Surface Height

NASA 2012: The transpolar drift (purple arrows) is a dominant circulation feature in the Arctic Ocean that carries freshwater runoff (red arrows) from rivers in Russia across the North Pole and south towards Greenland. Under changing atmospheric conditions, emergent circulation patterns (blue arrows) drive freshwater runoff east towards Canada, resulting in freshening of Arctic water…

Vanishing Arctic Ice and Amplification

While heat waves and more intense storms have been directly linked to a warming Earth, new research is exploring possible impacts of an Arctic that is warming at twice the pace of the rise in global temperatures. Jennifer Francis, Rutgers University, discusses new research and efforts to understand this controversial aspect of climate change in…

Atmospheric Oxygen Decline threatens Humanity’s Existence

Study: There has been a clear decline in the volume of oxygen in Earth’s atmosphere over the past 20 years. A recently proposed model predicts a non-linear decay, which would result in an increasingly rapid fall-off in atmospheric oxygen concentration, with potentially devastating consequences for human health. We predict that humans may continue to survive…

The Paleocene–Eocene Thermal Maximum 56 Mil yrs ago (PETM)

January 30, 2014 – Deep Time, Global Change and YOU lecture series: Global Warming 56 Million Years Ago & What it Means for Us. Presented by Dr. Scott Wing, Smithsonian Institute Human greenhouse gas emissions will alter conditions on earth for thousands of years. The past event that best mirrors current warming occurred 56 million…

Drew Shindell: Climate Policy to Avoid Tipping Points

Head of the SAP, Drew Shindell, talks about why a near-term climate goal is important, the main message the article aims to convey, why governments should adopt a near-term goal, and whether reducing near-term warming can prevent climate tipping points. The Climate and Clean Air Coalition’s Scientific Advisory Panel (SAP) published an article in Science…

Like Champagne opened, methane explosions resulted in Ocean craters

Like ‘champagne bottles being opened’: Scientists document an ancient Arctic methane explosion What could possibly go wrong, ignoring climate change, the warnings or clues from what science tells us, even if we were just creating a better world with clean energy, and millions of new jobs? One thing which could go very wrong, are based…

Global Average Temperature vs Temperature Extremes

In his March 2017 talk “The Brutal Logic of Climate Change”, at the University of Sheffield, Aaron Thierry outlined many of the aspects of climate change. This video here is the excerpt on temperature anomalies. Watch the full lecture at https://www.youtube.com/watch?v=r7TL_BbAd-s The emissions pledge pathway negotiated at the Paris conference has a probability of over…

Climate Data Mysteries, Wonders, and Reality (April 2017)

Event 18 April, 2017 – sponsored by The Department of Earth, Atmospheric and Planetary Sciences (EAPS) and the Center for Global Change Science. Climate data comes in a rich variety of quality with varying time and space…

NASA Discovers a New Mode of Ice Loss in Greenland (Solitary Wave)

A new NASA study finds that during Greenland’s hottest summers on record, 2010 and 2012, the ice in Rink Glacier on the island’s west coast didn’t just melt faster than usual, it slid through the glacier’s interior in a gigantic wave, like a warmed freezer pop sliding out of its plastic casing. https://www.jpl.nasa.gov/news/news.php?feature=6857 “You could…

Climate Change in the Arctic and Model Projections

This video with scope on permafrost melting, highlights some of the new developments of our understandings, of what happens in the Arctic due to global warming. The Woods Hole Research Center (WHRC), at the University of Alaska Fairbanks May 11, 2017. Professor of Geophysics Vladimir Romanovsky discusses the impact of Arctic permafrost thaw.
