'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.
'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.
'Capturing carbon from air only way to save earth'September 24th, 2009 TORONTO - Capturing carbon directly from the air is the only way to prevent dangerous climate changes, says a pioneering Canadian scientist. University of Calgary scientist David Keith says governments need to earmark more research funding for technologies to capture carbon dioxide in surrounding air to save the planet.
Scientists may have discovered Homo sapiens' oldest known trackways in TanzaniaSeptember 16th, 2009 WASHINGTON - A team of researchers from the Appalachian State University, US, is investigating in Tanzania, East Africa, what may represent the oldest known and best-preserved trackways of modern humans (Homo sapiens) in the world. The research is being carried out by Dr.
Climate change mitigation strategies ignore carbon cycling processes of inland watersSeptember 2nd, 2009 WASHINGTON - In a new research, scientists have said that current international strategies to mitigate manmade carbon emissions and address climate change have overlooked the carbon cycling processes of inland waters. The research was carried out by scientists from the University of Vienna, Uppsala University in Sweden, University of Antwerp, and the US based Stroud Water Research Center.
Largest dinosaur footprints in Europe discoveredAugust 19th, 2009 LONDON - Scientists have found the largest dinosaur footprints ever to be discovered in Europe, which are discovered half way up a Swiss mountain. According to a report in the Telegraph, a team of paleontologists from the Natural History Museum in Basel found the prints at 3,300 metres on a mountain in Ela Nature Reserve, Switzerland's largest park.
US government's 'Cash for Clunkers' program expensive way to reduce CO2August 15th, 2009 WASHINGTON - New estimates by researchers at University of California (UC) Davis have indicated that the US government's 'Cash for Clunkers' program is paying at least 10 times the "sticker price" to reduce emissions of the greenhouse gas carbon dioxide (CO2). While carbon credits are projected to sell in the US for about 28 dollars per ton, even the best-case calculation of the cost of the clunkers rebate is 237 dollars per ton, according to UC Davis transportation economist Christopher Knittel.
Pacific Northwest forests hold significant potential to increase carbon storageJuly 3rd, 2009 WASHINGTON - A new study has determined that the forests of the Pacific Northwest hold significant potential to increase carbon storage and help mitigate greenhouse gas emissions in the coming years. In the complete absence of stand-replacing disturbances - via fire or timber harvest - forests of Oregon and Northern California could theoretically almost double their carbon storage.
Oz scientists closer to identify mystery light that lit up universeJune 21st, 2009 SYDNEY - Scientists in Australia are getting closer to identify the mystery light that lit up the universe. The universe was covered in a thick fog of neutral hydrogen gas thirteen billion years ago.
Scientists find direct relationship between CO2 emissions and global warmingJune 11th, 2009 WASHINGTON - In a new study, a team of scientists has found a direct relationship between carbon dioxide (CO2) emissions and global warming. The study was done by Damon Matthews, a professor in Concordia University's Department of Geography, Planning and the Environment, along with colleagues from Victoria and the UK.
Agriculture could become big part of solution to global warmingJune 4th, 2009 WASHINGTON - A new report released by the Worldwatch Institute has said that agriculture could become a big part of the solution to global warming. According to a report in Environmental News Network (ENN), innovations in food production and land use that are ready to be put to work could reduce greenhouse gas emissions equivalent to roughly 25 percent of global fossil fuel emissions and be managed to reduce carbon already in the atmosphere as well.
Scientists transform CO2 into clean-burning biofuelApril 17th, 2009 WASHINGTON - Scientists at Singapore's Institute of Bioengineering and Nanotechnology (IBN) have become the first to transform the greenhouse gas carbon dioxide (CO2) into methanol, which is a widely used industrial feedstock and clean-burning biofuel. The IBN researchers report that by using organocatalysts, they activated CO2 in a mild and non-toxic process to produce methanol, a widely used industrial feedstock and clean-burning biofuel.
Wind pattern change may intensify global warmingMarch 14th, 2009 WASHINGTON - Carbon dioxide released from the Antartic Ocean due to shifting wind patterns may drastically increase global warming, say scientists. Many scientists think that the end of the last ice age was triggered by a change in earth's orbit that caused the northern part of the planet to warm.
Underground rocks may turn carbon dioxide into harmless chemicalMarch 6th, 2009 WASHINGTON - Geologists have mapped large rock formations in the US that can absorb carbon dioxide and potentially be harnessed to vastly accelerate the process. The report, by scientists at Columbia University's Earth Institute and the US Geological Survey, shows 15,000 square km of ultramafic rocks at or near the surface.
NASA to launch carbon dioxide tracking satellite TuesdayFebruary 24th, 2009 WASHINGTON - Scientists hope to get a clearer picture of how the Earth reacts to carbon dioxide with the launch Tuesday of a new spacecraft designed to collect data on the climate-changing gas. The Orbiting Carbon Observatory is set for launch early Tuesday from California and will take about eight million measurements every 16 days for the next two years.
