Projection of the what the first Antarctic ice sheet might have looked like as the global climate cooled about 33.5 million years ago. Antarctica is in gray, with the ice sheet shown in meters of ice thickness. The ice sheet is continental in scale, but somewhat smaller than today. The estimate is based on prior modeling work of DeConto and Pollard and is supported by this new data study.…Posts Tagged ‘Carbon Dioxide’
Carbon Dioxide Drop And Global Cooling Caused Antarctic Glacier To Form

Comments OffUnlike Diamonds, Most Minerals Not Forever
February 24th, 2009 Malvika Sampat 
From Live Science:
Diamonds may be forever, but that’s not true of most minerals. In fact, about two-thirds of the 4,300 known minerals on Earth today owe their existence to biological processes, and thus evolved fairly recently in geological terms. So says Robert M. Hazen of the Carnegie Institution in Washington, D.C., who with seven colleagues identified three phases of mineral evolution.…

February 17th, 2009 Malvika Sampat 
From Watts Up With That?
NASA’s Dr. James Hansen once again goes over the top. See his most recent article in the UK Guardian. Some excerpts:
“The trains carrying coal to power plants are death trains. Coal-fired power plants are factories of death.”
And this:
Clearly, if we burn all fossil fuels, we will destroy the planet we know.…

February 9th, 2009 Malvika Sampat 
The laser light source used in this study was developed in the Physics Department at Imperial College and the technology transferred to RAL. It is capable of producing ultra-short pulses of light of very high intensity which are made up of a broad range of colours. (Credit: Image courtesy of Imperial College London)From Science Daily:

January 19th, 2009 Malvika Sampat 
Plumes of up to 19,000 tons of methane, pictured red,were detected in Mars’ northern hemisphere
From The Daily Mail:
If there is life on Mars as NASA scientists claim, this is where it lives.
This extraordinarily detailed picture shows exactly where the most methane, taken as an indication of life, can be found.…

January 5th, 2009 Malvika Sampat Wasteful energy policies, overuse of resources, water supply shortages, global climate change, and deforestation are just some of the issues experts say need to be addressed for humans to achieve sustainable living on this planet. By the year 2025, an additional 2.9 billion people will strain tightening water supplies, and the world’s energy needs will go up 60 percent by 2030, according to the United Nations.…

December 8th, 2008 Malvika Sampat 
Researchers speculate that during the Cryogenian Period, about 840 to 635 million years ago, advancing ice was stalled by the interaction of the physical climate system and the carbon cycle of the ocean, with carbon dioxide playing a key role in insulating the planet.
