Greenland and Antarctica ice loss accelerating

November 29th, 2012 by University of Washington

Forty-seven research scientists from 26 laboratories have reconciled their measurements of ice sheet changes in Antarctica and Greenland during the past two decades and found that ice has been lost faster during the last decade. The results, published in the paper “A Reconciled Estimate of Ice-Sheet Mass Balance” in the journal Science, roughly halve the […]

More accurate climate modelling predicts greater global warming

November 10th, 2012 by The University Corporation for Atmospheric Research

According to analysis by scientists at the National Center for Atmospheric Research (NCAR), climate model projections showing a greater rise in global temperature are likely to prove more accurate than those showing a lesser rise. The report “A Less Cloudy Future: The Role of Subtropical Subsidence in Climate Sensitivity” published in Science, could provide a […]

Earth warming during reduced solar output

February 1st, 2012 by NASA Goddard Institute for Space Studies

A NASA study underscores the fact that greenhouse gases generated by human activity — not changes in solar activity — are the primary force driving global warming. The study, ‘Earth’s energy imbalance and implications’, published in Atmospheric Chemistry and Physics in December 2011, offers an updated calculation of the Earth’s energy imbalance, the difference between the […]

Global warming confirmed by 1.6 billion temperature records made during last 200 years

November 1st, 2011 by Berkeley Earth

Global warming is real, according to a major study by Berkeley Earth released on 20 October 2011. Despite issues raised by climate change skeptics, the Berkeley Earth Surface Temperature study found reliable evidence of a rise in the average world land temperature of approximately 1° Celsius since the mid-1950s. Berkeley Earth video representation of the […]

350.org founder Bill McKibben speaks at Power Shift 2011 about the urgency of reducing carbon emissions

April 18th, 2011 by Richard Lord

Bill McKibben said “the science is clear. We have a number, 350 parts per million. 350 – the most important number on Earth as the NASA team put it in January 2008.” “Any value for carbon in the atmosphere greater than 350 parts per million is not compatible with the planet on which civilisation developed, […]

NASA satellites study earth systems in minute detail to understand and record climate change

February 9th, 2011 by Richard Lord

Global Warming: Each year, scientists at NASA’s Goddard Institute for Space Studies analyze global temperature data. The past year, 2009, tied as the second warmest year since global instrumental temperature records began 130 years ago. Worldwide, the mean temperature was 0.57°C (1.03°F) warmer than the 1951-1980 base period. And January 2000 to December 2009 came […]
