Thawing Permafrost Could Release Vast Carbon Deposits, Diseases

by Science World Report | January 8, 2014 | Release URL Dr Guido Grosse has been studying the Arctic for fourteen years to find out how the frozen ground, known as the permafrost, is reacting to an environment that is getting hotter all the time. The samples he has drilled out – in regions so…

Why Climate Deniers Have No Scientific Credibility: Only 1 of 9,136 Recent Peer-Reviewed Authors Rejects Global Warming

I have brought my previous study (see here and here) up-to-date by reviewing peer-reviewed articles in scientific journals over the period from Nov. 12, 2012 through December 31, 2013. I found 2,258 articles, written by a total of 9,136 authors. (Download the chart above here.) Only one article, by a single author in the Herald of the Russian Academy of Sciences,…

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…

‘Global sunscreen’ plan could wreck tropics, study finds

by Richard Ingham | Phys.org | January 8, 2014 | Release  URL An idea by the father of the H-bomb to slow global warming by sowing the stratosphere with light-reflecting particles could wreck the weather system in the tropics, a study said Wednesday.  The scheme may benefit northern Europe and parts of Asia, but around…

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…

Yale: Climate, Jetstream and Polar Vortex


Blanket 24/7 media coverage of the short but frigid ‘Polar Vortex’ temperatures — climate change? global warming? — provides a cornucopia of material for this month’s ‘This is Not Cool’ video.

Melting Point Greenland – 2012 Documentary

2013 National Headliners Award First Prize Environmental Reporting HD 42 mins In the summer of 2012, one of the most vital ecosystems on earth, the Greenland ice sheet, experienced a meltdown that alarmed scientists the world over. Greenland is an island encased in ice and it’s the world’s second largest ice sheet after Antarctica. That…

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.…

Polar Vortex, Jet Stream and Climate Change

Current coverage of polar vortex intrusion. ‘Polar vortex’ could send wind chill to 65 below zero in Midwest More realtime coverage Carson Walker: Temperature records will likely be broken during the short, yet forceful deep freeze that will begin in many places on Sunday and extend into early next week. That’s thanks to a perfect…

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…

USGS: Climate-Hydrate Interactions

The U.S. Geological Survey Gas Hydrates Project Release URL | Access date: January 3rd 2014. Climate studies in the USGS Gas Hydrates Project have become increasingly important since 2007 and focus on the impact of Late Pleistocene to contemporary climate change on the stability of methane hydrate deposits. The goal is to determine how much, if any,…

NRC: Abrupt Impacts of Climate Change (2013)

Published 3rd December 2013: National Research Council Abrupt Impacts of Climate Change: Anticipating Surprises | Release URL Both abrupt changes in the physical climate system and steady changes in climate that can trigger abrupt changes in other physical, biological, and human systems present possible threats to nature and society. Abrupt change is already underway in some…
