Permafrost soils in Canada’s Arctic are melting at a rate that will significantly speed up global warming, according to new research from the University of Victoria.

The study, published this week in Nature Geoscience, predicts that the thawing permafrost will release between 68 billion and 508 billion tonnes of carbon into the atmosphere by the year 2100.

As a result of those carbon emissions, researchers say the Earth’s temperature will rise by more than 0.5 C by the end of the century.

Although seemingly insignificant, that amount is in addition to the two degrees the Earth’s temperature is expected to rise because of global warming from industrial sources.

Andrew Weaver, a climate scientist at the University of Victoria and one of the study’s authors, warns that once the planet warms by more than two Read more…

Weather Extremes & Global Warming — The Connection

Seasonal Jun-Jul-Aug 2010 sea surface temperature (SST) anomalies relative to 1951–70. Record high SSTs were recorded in the locations and at the times indicated with record flooding nearby.

Curious about the connection between global warming and extreme weather? You ought to be. And who better to learn about this from than National Center for Atmospheric Research senior scientist Kevin E. Trenberth?

WASHINGTON — Nearly two-thirds of Americans believe that climate change is real — the highest level in two years — as the public trusted its own observations of rising temperatures, a poll said Tuesday.

The growing acceptance of global warming comes despite fierce political division over the issue in the world’s largest economy, with proposals to mandate cuts on carbon emissions failing in Congress.

Sixty-two percent of Americans agree that there is solid evidence that the Earth’s average temperature has been getting warmer over the past four decades, according to the survey by the University of Michigan’s Gerald Ford School of Public Policy and the Muhlenberg College Institute of Public Opinion.

Arctic Warming Continuing, Approaching Tipping Point?

Last year the Arctic, which is warming faster than anywhere else on Earth due to global climate change, experienced its warmest twelve months yet. According to recent data by NASA, average Arctic temperatures in 2011 were 2.28 degrees Celsius (4.1 degrees Fahrenheit) above those recorded from 1951-1980. As the Arctic warms, imperiling its biodiversity and indigenous people, researchers are increasingly concerned that the region will hit climatic tipping points that could severely impact the rest of the world. A recent commentary in Nature Climate Change highlighted a number of tipping points that keep scientists awake at night.

“If set in motion, [tipping points] can generate profound climate change which places the Arctic not at the periphery but at the core of the Earth system,” Professor Duarte, a climatologist with the University of Western Australia’s Ocean Institute and co-author other paper, said in a press release. “There is evidence that these forces are starting to Read more…

Manhattan-sized Glaciers Break off at Both Ends of the Globe

Following the recent report by MSNBC of a glacier break up in Greenland estimated at twice the size of Manhattan, the National Geographic now reported that another glacier in Antarctica, this time just about the size of Manhattan (is the size of Manhattan the rule of thumb when calculating glacier sizes?) is about to break off as well.

Experts relate that they are worried about the effects this may have on the rising sea level, but what about the collective effects ? Both sites are deemed responsible for possible changes to the ocean currents.

Take the North Atlantic for example, the gulf stream takes warm water from the tropics upstream towards the north, contributing to the warm climate in Europe. As the current hits Greenland it reaches fresh water which causes the salty water to sink and sends warm water back down towards the south.

The problem with glaciers breaking off and eventually melting is that it is reducing the salty warm water moving south, thus slowing down the entire flow. This flow reduction may cause Read more…

Global warming: European species lag in habitat shift

PARIS — Fast-track warming in Europe is making butterflies and birds fall behind in the move to cooler habitats and prompting a worrying turnover in alpine plant species, studies published Sunday said.

The papers, both published by the journal Nature Climate Change, are the biggest endeavour yet to pinpoint impacts on European biodiversity from accelerating global temperatures.

A team led by Vincent Devictor of France’s National Centre for Scientific Research (CNRS) found that from 1990 to 2008, average temperatures in Europe rose by one degree Celsius (1.8 degrees Fahrenheit).

This is extremely high, being around 25 percent greater than the global average for all of the last century.

In order to live at the same temperature, species would have to shift northward by 249 kilometres (155 miles), they calculated.

But during this period, butterlies moved only Read more…
