British Antarctic Survey Climate Review finds the Ozone Hole has Shielded Antarctica from Global Warming!
December 1, 2009 05:59 AM - Roger Greenway, ENN

An important report from the British Antarctic Survey (BAS) shows things aren’t always what they seem to be, and that our knowledge of our complex Earth is not a good as we thought. Sometimes problems are not what they seem to be, and sometimes a problem in one sense carries unknown benefits in other senses. The BAS is a global leader in studying the Antarctic, and it has recently published the first comprehensive review of the state of Antarctica’s climate and its relationship to the global climate system. The review — Antarctic Climate Change and the Environment — presents the latest research from the icy continent, identifies areas for future scientific research, and addresses the urgent questions that policy makers have about Antarctic melting, sea-level rise and biodiversity.

Mars Meteorite Reexamined for Signs of Life Using New Analysis
November 30, 2009 10:07 AM - Irene Klotz, Discovery News

A controversial Mars meteorite is once again in the spotlight as scientists use a new kind of analysis on the rock. The study is reminiscent of initial research, published in 1996, suggesting that tiny iron sulfide and iron oxide grains in the meteorite had biological origins, and that tiny, worm-shaped objects in the rock could be the fossilized remains of Martian microbes.

Spotlight: University of Minnesota

Anyone who knows anything about green movements, legislation, and popularization knows that the concept of framing is perhaps one of the most highly used tactics used by green activists and politicians to garner support for environmentalist causes. Basically, framing is the act of taking an issue and highlighting a more specific aspect of that issue to strike the interest and sympathy of supporters who might otherwise not have cared. Two of the most popular environmental frames are public health- based claims and economic claims.

COMMENTARY

A heated debate

The Economist, The World Business Council for Sustainable Development (WBCSD)
A majority of the world's climate scientists have convinced themselves, and also a lot of laymen, some of whom have political power, that the Earth's climate is changing; that the change, from humanity's point of view, is for the worse; and that the cause is human activity, in the form of excessive emissions of greenhouse gases such as carbon dioxide. A minority, though, are skeptical. Some think that recent, well-grounded data suggesting the Earth's average temperature is rising are explained by natural variations in solar radiation, and that this trend may be coming to an end. Others argue that longer-term evidence that modern temperatures are higher than they have been for hundreds or thousands of years is actually too flaky to be meaningful.
