Climate experts now believe that they have pinpointed yet another human-related cause of global warming: fires. Working as a sort of positive-feedback mechanism, climatologists now say they have evidence that human made fires "“ such as those used to clear forests "“ actually spawn more unintended fires.  In a report published in the April 24 edition of the journal Science, co-author Jennifer Balch of the University of Santa Barbara explained that the ash particles sent into...

U.S. government scientists say their research indicates the effects of significant global warming on Earth can no longer be avoided. But the researchers said a worldwide reduction in greenhouse gas emissions would reduce the effects, lessening sea-level rise and possibly saving Arctic Sea ice. The study, led by scientists at the National Center for Atmospheric Research, determined that if all nations cut emissions of heat-trapping greenhouse gases by 70 percent this century, the most...

A poll of scientists, released on Tuesday, showed that global warming is likely to overshoot a 3.6 degrees Fahrenheit rise, seen by the European Union and many developing nations as a trigger for "dangerous" change, Reuters reported. The evidence that mankind is to blame for climate change has grown stronger in the past two years, according to 9 of the 11 experts, who were among the authors of the final summary by the U.N.'s Intergovernmental Panel on Climate Change in 2007 (IPCC). The...

Researchers say more than 90 percent of U.S. citizens support governmental action to reduce global warming despite the current economic crisis. The results of a national survey prepared by researchers at Yale and George Mason Universities included 34 percent who said the United States should make such a major effort, even if it has large economic costs. And two-thirds of survey participants said the United States should reduce its emissions of greenhouse gases regardless of what other...

COPENHAGEN, Denmark, March 12 /PRNewswire-USNewswire/ -- The following is being released by the Institute for Governance & Sustainable Development: The need for urgent action has been emerging as a primary theme of the Copenhagen Climate Congress this week - including urgent action on mitigation strategies that complement aggressive cuts in CO2 emissions. "Everyone must understand the urgency of this matter and the potential costs," Danish Minister of Climate and Energy Connie Hedegaard...

Scientists at a Denmark conference say rising sea levels will have a major negative impact on 1-in-10 humans living in the Earth's low-lying coastal areas. Research presented during this week's International Scientific Congress on Climate Change in Copenhagen shows the upper range of sea level rise by 2100 could be in the range of about 1 meter (3 feet) or possibly more. At the lower end of the spectrum, studies show it is increasingly unlikely sea level rise will be much less than 50...

More than 2,000 climate scientists gathered in Copenhagen on Tuesday to focus on global warming's rapid acceleration, the AFP reported. New research suggests the impact of global warming could be even worse than predicted by the UN Intergovernmental Panel on Climate Change (IPCC) in 2007, with natural disasters like floods, drought, disease and extreme weather, arriving sooner rather than later. Scientists fear the possibility that human activity -- mainly the burning of oil, gas and...

 A new study by scientists updating some of the findings of the Intergovernmental Panel on Climate Change (IPCC) 2001 Third Assessment Report finds that even a lower level of increase in average global temperatures due to greenhouse gas emissions could cause significant problems in five key areas of global concern.The study, published in the Proceedings of the National Academy of Sciences, is titled "Assessing Dangerous Climate Change Through an Update of the IPCC 'Reasons for...

A U.S. scientist says Earth's atmospheric greenhouse gases are increasing more rapidly than expected, resulting in worsening global warming predictions. Chris Field, a member of the Nobel Prize-winning Intergovernmental Panel on Climate Change, says decisive action is needed to prevent the planet's climate system from crossing a critical threshold by the end of the century. Field, director of the Carnegie Institution's Department of Global Ecology, said studies indicate greenhouse warming...
