Latest Global cooling Stories
Researchers claiming to have found the Earth could be entering a cooling cycle may have gotten their facts wrong, according to a recent independent study.The Associated Press commissioned a study from independent statistics professors to analyze figures without being told what they represented.University of South Carolina statistics professor John Grego, along with David Peterson, retired from Duke University, Mack Shelley, director of public policy and administration at Iowa State University...
On the scientific research front, most news headlines tend to be aimed at showing how global temperatures are on a steady upward climb, but one report published last week appears to reveal that those upward trends may not be entirely accurate.In an October 9 BBC News story, climate correspondent Paul Hudson noted that the warmest year on record was not in 2008 or 2007, but in 1998.The story goes on to state that no climate increase has been measured over the past 11 years, although emissions...
Everybody talks about CO2 and other greenhouse gases as causes of global warming and the large climate changes we are currently experiencing. But what about the atmospheric and oceanic oxygen content? Which role does oxygen content play in global warming?This question has become extremely relevant now that Professor Robert Frei from the Department of Geography and Geology at the University of Copenhagen, in collaboration with colleagues from Uruguay, England and the University of Southern...
U.S. scientists say people denying global warming due to short-term periods of cooling don't understand the statistical insignificance of such periods. David Easterling of the National Climatic Data Center in Asheville, N.C., and Michael Wehner of the Lawrence Berkeley National Laboratory in Berkeley, Calif., said some Web sites and media articles have noted the average global temperature has not risen since 1998 and cite that as evidence against anthropogenic, or human-caused, global...
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...
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 freezeA 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 cultureNSF - 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...
By Patricia Reaney LONDON (Reuters) - Global temperatures in the future couldbe much hotter than scientists have predicted if new computermodels on climate change are correct, researchers said onWednesday. Improvements in air quality will lead to a decrease inaerosols, small particles in the atmosphere that act as a brakeon the impact of greenhouse gases. As the effect of aerosolslessen, searing temperatures could follow. "This new way of integrating the aerosol, greenhouse gasand biosphere...
