Global Warming Speed Bump? The Answer May Be Blowing in the Wind!

By Michael E. Mann via HuffingtonPost: An interesting new paper by Matthew England and colleagues just published in the journal Nature Climate Change tosses another hat in the ring when it comes to explanations of the so-called “hiatus” or “pause” (I prefer “speed bump”) in global warming. As I have discussed previously, the fact that global surface temperatures have not increased…

Arctic Lakes Show Climate On Thin Ice

ESA reported on February 3, 2014: Ice in northern Alaska’s lakes during winter months is on the decline. Twenty years of satellite radar imagery show how changes in our climate are affecting high-latitude environments. Changes in air temperature and winter precipitation over the last five decades have affected the timing, duration and thickness of the ice…

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…

UK Floods 2014 Could Last for Months + 1.6M Homes at Risk for Flooding

Andy McKenzie, a groundwater scientist at the British Geological Survey, told Sky News that even if the rain stopped today, so much water is soaking through the soil that levels are likely to keep rising for another two months. The risk of flooding could remain high until May, he said. According to the data from the…

2013 Is the Fourth Hottest Year on Record

By Phil Plait (Slate):  It’s official: 2013 is the fourth hottest year since records started being kept in 1880. It ties with 2003 for that dubious honor. This result was just announced by the National Oceanic and Atmospheric Administration. It uses global annual land and sea surface temperatures to make the call, and in 2013 these two measures combined…

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…

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…

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…

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…

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,…

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…

Planet likely to warm by 4C by 2100, scientists warn

Peter Sinclair: Sherwood’s paper shoots more holes into lingering hopes that climate sensitivity, the amount of warming we expect for a given rise in CO2, might be lower than we thought – that maybe temp rises could be more moderate in the future. One of the last, lingering, tattered bastions of climate denial has been that, somehow,…
