U.S. researchers say a reduction in greenhouse gases likely caused the relatively swift formation of ice in Antarctica millions of years ago. Matthew Huber, assistant professor of earth and atmospheric sciences at Purdue University, said ice formed on Antarctica 35.5 million years ago over a period of about 100,000 years. That is considered an overnight shift in geological terms, the university said Thursday in a release. Our studies show that just over 35 million years ago, 'poof,' there was...

Aerosols may have a greater impact on patterns of Australian rainfall and future climate change than previously thought, according to leading atmospheric scientist, CSIRO's Dr Leon Rotstayn. "We have identified that the extensive pollution haze emanating from Asia may be re-shaping rainfall patterns in northern Australia but we wonder what impact natural and human-generated aerosols are having across the rest of the country," Dr Rotstayn said. Aerosols are fine particles suspended in the...

The power of viruses is well documented in human history. Swarms of little viral Davids have repeatedly laid low the great Goliaths of human civilization, most famously in the devastating pandemics that swept the New World during European conquest and settlement.In recent years, there has been growing evidence for the hypothesis that the effect of the pandemics in the Americas wasn't confined to killing indigenous peoples. Global climate appears to have been altered as well.Stanford...

New evidence could solve the puzzle of why Antarctica went into the deep freeze A team of scientists from Cardiff University's School of Earth and Ocean Sciences and Amgueddfa Cymru - National Museum Wales travelled to Africa to find new evidence of climate change which helps explain some of the mystery surrounding the appearance of the Antarctic ice sheet. Ice sheet formation in the Antarctic is one of the most important climatic shifts in Earth's history. However, previous temperature...

Caused wooly mammoth extinction, global cooling and end of early human Clovis culture NSF - New scientific findings suggest that a large comet may have exploded over North America 12,900 years ago, explaining riddles that scientists have wrestled with for decades, including an abrupt cooling of much of the planet and the extinction of large mammals. The discovery was made by scientists from the University of California at Santa Barbara and their colleagues. James Kennett, a paleoceanographer...

LONDON -- Global temperatures in the future could be much hotter than scientists have predicted if new computer models on climate change are correct, researchers said on Wednesday. Improvements in air quality will lead to a decrease in aerosols, small particles in the atmosphere that act as a brake on the impact of greenhouse gases. As the effect of aerosols lessen, searing temperatures could follow. "This new way of integrating the aerosol, greenhouse gas and biosphere effects changes the...

Bonn study shows: Since 1880 climate gases have caused just under half of global warming Bonn -- In the last 120 years the average global temperature has risen by 0.7 degrees. Over the same period the carbon dioxide concentration in the atmosphere increased from 0.28 to 0.37 per cent. Carbon dioxide is one of the so-called 'greenhouse gases'; methane, which is produced as part of the process of cattle-rearing, for example, is also a greenhouse gas. Its concentration in the atmosphere has...
