Current loss of Arctic sea ice mostly caused by human activity

July 26th, 2012 by University of Reading

Natural climate variations could explain up to 30% of the loss in Arctic sea ice since the 1970s, scientists have found. Sea ice coverage at the North Pole has shrunk dramatically over the past 40 years. The ice is now more than a third smaller each September following the summer melt than it was in […]

WMO reports that last decade saw climate changing more rapidly

March 24th, 2012 by World Meteorological Organization

The World Meteorological Organization’s Annual Statement on the Status of the Global Climate said that 2011 was the 11th warmest since records began in 1850. It confirmed preliminary findings that 2011 was the warmest year on record with a La Niña, which has a cooling influence. Globally-averaged temperatures in 2011 were estimated to be 0.40° […]

Global temperatures in 2011 higher than in any previous La Niña year

December 4th, 2011 by World Meteorological Organization

Global temperatures in 2011 are currently the tenth highest on record and are higher than any previous year with a La Niña event, which has a relative cooling influence. The 13 warmest years have all occurred in the 15 years since 1997. The extent of Arctic sea ice in 2011 was the second lowest on […]

New climate modelling to explain dramatic decline in Arctic sea ice

October 8th, 2011 by Le Centre National de la Recherche Scientifique

In recent decades, Arctic sea ice has suffered a dramatic decline that exceeds climate model predictions. The unexpected rate of ice shrinkage has now been explained by researchers at CNRS, Université Joseph Fourier and Massachusetts Institute of Technology.

Can walking to work save the polar bear?

May 6th, 2011 by Richard Lord

This video was posted to youtube in March 2009. Climate change is reducing the number of months that polar bears can hunt on Arctic sea ice.  As a consequence the polar bear population in the Hudson Bay area is declining. Human induced climate change occurs as we emit more greenhouse gases into the atmosphere from […]

Researchers from Potsdam Institute for Climate Impact Research find that Global Warming could cool down temperatures in winter

November 17th, 2010 by Potsdam Institute for Climate Impact Research

The overall warming of the earth’s northern half could result in cold winters. The shrinking of sea-ice in the eastern Arctic causes some regional heating of the lower levels of air – which may lead to strong anomalies in atmospheric airstreams, triggering an overall cooling of the northern continents, a study recently published in the […]
