'Green' roofs help reduce global warmingSeptember 24th, 2009 WASHINGTON - Roofs full of green plants could help fight global warming, say scientists. Kristin Getter, Michigan State University (MSU) horticulturist and colleagues, who conducted the study point out that green roofs are multi-functional.
'Green' roofs may help fight global warmingSeptember 24th, 2009 WASHINGTON - Scientists in Michigan, US, have reported that "green" roofs, which are popular urban rooftops covered with plants, could help fight global warming. The scientists found that replacing traditional roofing materials in an urban area the size of Detroit, with a population of about one-million, with green roofs would be equivalent to eliminating a year's worth of carbon dioxide (CO2) emitted by 10,000 mid-sized SUVs and trucks.
Arctic ice to last until 2030 to 2040September 22nd, 2009 WASHINGTON - New findings by scientists indicate that that Arctic ice would last decades longer than thought, and the region won't experience ice-free summers until 2030 or 2040. Some models had previously predicted that the Arctic could be ice free in summer by as soon as 2013, due to rising temperatures from global warming.
Arctic sea ice cover reaches minimum extent for 2009September 18th, 2009 WASHINGTON - A new study has found that the Arctic sea ice cover appears to have reached its minimum extent for this year, the third-lowest recorded since satellites began measuring sea ice extent in 1979. The study was carried out by researchers from to the University of Colorado at Boulder's National Snow and Ice Data Center.
Sea ice melting in Arctic remains far worse than normal, but only ranks No. 3 in record booksSeptember 17th, 2009 Arctic sea ice melt still heavy, but no recordWASHINGTON — The summer melt of Arctic sea ice wasn't quite as bad this year as the last two years. But it still ranked as the third biggest melt on record.
Global warming may make the Arctic of today a thing of the pastSeptember 11th, 2009 WASHINGTON - If a new research is anything to go by, then the Arctic as we know it may soon be a thing of the past, with global warming causing dramatic biological responses in the region. The research was led by Eric Post, associate professor of biology at Penn State University, along with a large, international team that carried out ecosystem-wide studies of the biological response to Arctic warming during the fourth International Polar Year, which ended in 2008.
Methane under permafrost could speed up global warming 20-foldSeptember 3rd, 2009 WASHINGTON - Melting permafrost in arctic regions, triggered by global warming, will release underground methane. Once released, methane would speed up global warming by trapping the earths heat radiation about 20 times more efficiently than the greenhouse gas, carbon dioxide.
Global warming bringing more extreme heat wavesAugust 30th, 2009 WASHINGTON - A new report from the National Wildlife Federation and Physicians for Social Responsibility, US, has determined that global warming is bringing more frequent and severe heat waves and the result will be serious for vulnerable populations. "That means air pollution in urban areas could get worse, bringing increased risk of heart attacks, strokes and asthma attacks.
Arctic Ocean may turn into 'polluted soup' by 2070August 7th, 2009 WASHINGTON - A climate model has predicted that global warming, combined with nuclear waste, may make the Arctic Ocean a polluted soup by the year 2070. According to a report in New Scientist, Ola Johannessen, director of the Nansen Environmental and Remote Sensing Center in Bergen, Norway, and his colleagues, developed the model.
Scientists' best predictions about global warming might be incorrectJuly 15th, 2009 WASHINGTON - A new study has suggested that scientists' best predictions about global warming might be incorrect. The study found that climate models explain only about half of the heating that occurred during a well-documented period of rapid global warming in Earth's ancient past.
Arctic could teem with life by 2030 due to global warmingJuly 9th, 2009 LONDON - In a new study, scientists have said that as global warming removes the Arctic's icy lid, the region is expected to teem with life by the year 2030. According to a report in New Scientist, the study of what the Arctic looked like just before dinosaurs were wiped off the planet has provided a glimpse of what could be to come within decades.
Sediments deposited in oceans by major Arctic rivers hold clues to future global climateMay 19th, 2009 WASHINGTON - A new study has suggested that sediments deposited in the ocean by major Arctic rivers may hold clues to understand how Earth's climate will change in the next few decades. The study was carried out by geoscientists at The University of Texas at Austin and Texas A and M University, US.
Mercury levels in Arctic seals may be linked to global warmingMay 4th, 2009 WASHINGTON - In a new study, researchers in Canada are reporting for the first time that high mercury levels in certain Arctic seals appear to be linked to vanishing sea ice caused by global warming. The study, by scientist Gary Stern and his colleagues, provides a new insight into the impact of climate change on Arctic marine life.
Ashley Judd, TV host Jeff Corwin call on Congress to help wildlife survive global warmingApril 23rd, 2009 Ashley Judd urges Congress to fight global warmingWASHINGTON — Actress Ashley Judd and TV personality Jeff Corwin are urging Congress to spend $7 billion a year to help safeguard America's wildlife from the impact of global warming. Judd is a longtime environmental activist.
Global warming might reduce if nations cut greenhouse gas emissions by 70 percentApril 15th, 2009 WASHINGTON - A new analysis has determined that the threat of global warming can still be greatly diminished if nations cut emissions of heat-trapping greenhouse gases by 70 percent this century. The analysis was done by scientists at the National Center for Atmospheric Research (NCAR).
