In a new report from the National Science Foundation, researchers outline signs of global warming discovered "from the icy expanses of the polar regions of Earth to its equatorial ecosystems." The 114-page report titled "Solving the Puzzle: Researching the Impacts of Climate Change Around the World," addresses key research findings from the Earth elements of sky, sea, ice, land, life and people. "Climate is a fundamental factor in ecosystem health," researchers wrote. "While most species can...

Though greenhouse gases are invariably at the center of discussions about global climate change, new NASA research suggests that much of the atmospheric warming observed in the Arctic since 1976 may be due to changes in tiny airborne particles called aerosols. Emitted by natural and human sources, aerosols can directly influence climate by reflecting or absorbing the sun's radiation. The small particles also affect climate indirectly by seeding clouds and changing cloud properties, such as...

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...

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...

According to a top climate scientist, warnings about global warming have not been severe enough. Just over a year ago, the Nobel-winning Intergovernmental Panel on Climate Change (IPCC) issued a report warning of expanding deserts, intense storms, rising sea levels, and an extinction of up to 30 percent of animals and plants due to global warming. A recent study suggests that the report underestimated the severity of climate change over the next century, says a senior member of the IPCC. "We...

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...

According to researchers, Europe's temperatures have risen over the past 30 years due to fewer misty, hazy, and foggy days. The finding could help researchers predict future climate changes. Five to ten percent of the region's warmer temperatures can be attributed to clearer skies and less air pollution says Geert Jan van Oldenborgh, a scientist from the Royal Netherlands Meteorological Institute. "The temperatures in Europe have been going up twice as fast as climate models had predicted in...

The Worldwatch Institute released a new report on Tuesday that advises sweeping changes must be made to limit global emissions by 2050. In its report, titled "State of the World 2009: Into A Warming World," authors say that even a small increase of up to 3.6 degrees F in global temperatures could result in dangerous threats to natural systems. In order to avoid these threats, the report says that world carbon emissions will have to drop to near zero by 2050 and "go negative" after that....

British climate scientists said on Tuesday that the coming year is likely to be one of the top-five warmest on record. Despite the continued cooling of huge areas of the Pacific Ocean "” a phenomenon known as La Nina"”the average global temperature for 2009 is expected to be more than 0.4 degrees Celsius above the long-term average. According to researchers at the Met Office, that would make it the warmest year since 2005, as there is also a growing probability of record...
