White House: The Polar Vortex Explained in 2 Minutes

by Becky Fried | January 08, 2014  | Release URL Here at the White House, while we’re beginning to thaw from this week’s bone-chilling deep freeze, our discussions about the science of weather extremes are heating up. We know that no single weather episode proves or disproves climate change. Climate refers to the patterns observed in the weather…

In Much of U.S., Extreme Cold is Becoming More Rare

The deep freeze that continues to affect the U.S. has resulted in numerous daily temperature records, and some all-time cold temperature records. But in general, this Arctic outbreak, courtesy of a huge chunk of the polar vortex that the jet stream temporarily dislodged from the Arctic, is bringing the coldest temperatures in 20 to 30…

The Science of the Polar Vortex and Jet Stream

At least since around 2001 we have study papers connecting the polar vortex / jet stream behavior to anomalies, such as cold weather outbreaks or precipitation changes. The polar vortex phenomenon was described as early as 1853. In recent years studies linked changes in the cryosphere to the polar vortex. Feel free to suggest further study papers in the comments.…

Antarctica’s ice loss on the rise (December 2013)

Published 11 December 2013 | Release URL (ESA CryoSat) Three years of observations by ESA’s CryoSat satellite show that the West Antarctic Ice Sheet is losing over 150 cubic kilometres of ice each year – considerably more than when last surveyed. The imbalance in West Antarctica continues to be dominated by ice losses from glaciers flowing…

Extensive ice in Antarctica

Released by National Snow and Ice Data Center | Access date January 4, 2013. While it is early winter in the Arctic, it is early summer in the Antarctic. Continuing patterns seen in recent years, Antarctic sea ice extent remains unusually high, near or above previous daily maximum values for each day in November. Sea ice…

Why is Antarctic sea ice growing?

Published on Nov 8, 2012: Suggestions that modest increases in sea ice around Antarctica offset significant losses in Arctic sea ice are based on a bogus “apples and oranges” comparison. Through interviews with a range of respected experts, Peter Sinclair’s newest Yale Forum video explains why such suggestions do not stand up to scientific scrutiny. Related…

Chris Hayes & Michael E Mann: There’s Global Warming – And It’s Snowing

Chris Hayes from MSNBC talks to Michael E Mann about global warming deniers and the season we call “winter.” Release with full segment URL Chris Mooney in MotherJones: 1. Statements about climate trends must be based on, er, trends. Not individual events or occurrences. Weather is not climate, and anecdotes are not statistics. 2. Global warming is actually…

2013 was hottest year on record in Australia

Australia has just sweltered through its hottest year on record, according to the Bureau of Meteorology. Average temperatures were 1.20 degrees Celsius above the long-term average of 21.8C, breaking the previous record set in 2005 by 0.17C. Professor Karoly: “In the model experiments, it is not possible to reach such a temperature record due to natural climate…
