UT Professor Debunks Climate Change "Myths"October 11th, 2011Raymond Orbach, is wading into the debate with a new paper aiming to debunk eight "myths" about climate change.
The paper, "Our Sustainable Earth," appears in the forthcoming issue of Reports on Progress in Physics, a British journal known for encouraging (relatively) simple language from its contributors. In it, Orbach summarizes existing scientific evidence to argue that humans bear responsibility for climate change and an 80 percent reduction in carbon-dioxide emissions by 2050 is needed to stabilize global temperatures. Otherwise, he writes, "current global temperature rises will continue, and even accelerate" as greenhouse gas concentrations keep rising.'Climate' genes in plants studiedOctober 11th, 2011U.S. scientists say knowledge of how plants adapt to local climates is vital to promoting agricultural and conservation successes in the face of climate change.
Texas cattle ranchers adapt to climate changeOctober 11th, 2011Everyone knows that Texas has been hot and dry. Cattlemen are responding to this new news. Given that they expect that this drought will continue, they are seeking out new "verdant" areas to raise their cattle. Investment under uncertainty and rational expectations lives on.Modern ecosystems feel ancient climate change effectOctober 11th, 2011Earth's animals migrate to ensure their survival in suitable conditions. This is especially true when climate cycles switch between warm and cool periods. Now researchers in Denmark and the United Kingdom shed new light on how quickly species have had to migrate in the past in order to keep pace with the changing climate. Presented in the journal Science, the findings show how small-ranged species - which account for most of the planets biodiversity - have found a niche in areas where migration has not been intense. Laying the Blame for Extreme WeatherOctober 11th, 2011Floods, tornadoes, droughts and wildfires: They are all weather-related, but blaming the latest meteorological disaster on climate change has always been a tricky matter that climate scientists have been shy to do. After all, how can you point to a specific and local event, such as a tornado or dry spell, and say it is caused by something as long-term and huge as global warming?Steep Increase in Global CO2 Emissions Despite Reductions by Industrialized Countries With Binding Kyoto TargetsSeptember 21st, 2011Global emissions of carbon dioxide (CO2) -- the main cause of global warming -- increased by 45 % between 1990 and 2010.Climate change: Species climbing higher and migrating north, study saysAugust 19th, 2011Organisms are responding to climate change at a pace much faster than scientists estimated about a decade ago, according to a new study in the journal Science.NASA Map Reveals Climate Change CluesAugust 19th, 2011NASA funded researchers have created the first complete map of the speed and direction of ice flow in Antarctica. Climate change affecting Atlantic mackerelAugust 12th, 2011Environmental factors have affected Atlantic mackerel from Cape Hatteras, N.C., to Newfoundland, shifting them northeast into shallower waters, researchers say.
A green lining to climate changeAugust 7th, 2011His team has found that increased carbon dioxide levels increase the efficiency of how plants use water, reducing the amount of water grasses and weeds allow to escape into the soil. next page
