Delay in Autumn Colour is Caused by Increased Atmospheric CO2 not Global Warming
November 19, 2007 08:44 AM - University of Southampton
The delay in autumnal leaf coloration and leaf fall in trees is caused by rising levels of carbon dioxide (CO2) in the atmosphere and not by increased global temperatures, suggests a new study by researchers at the University of Southampton.
In recent years, woodland autumnal colour changes have been occurring later in the season whilst re-greening in spring has been occurring earlier. During the last 30 years across Europe, autumnal senescence – the process of plant aging where leaves discolour and then fall – has been delayed by 1.3 - 1.8 days a decade. To date, this has been explained by global warming, with increasing temperatures causing longer growing seasons.
Act Now on Climate Change: Go For Energy Efficiency.
November 19, 2007 08:06 AM - , Private Landowner Network
The latest report on the state of global warming from the Intergovernmental Panel on Climate Change ((IPCC) warns that without action soon climate change may cause abrupt and irreversible impacts.
(Glaciers, like those on Greenland, may experience rapid meltdown and cause sea levels to rise. Once gone glaciers won’t freeze up again. Droughts similar to that now being experienced in the southeast US may be more frequent and perhaps permanent. Populations without water to support them will have to move, never to return.)
Iron is a tonic for climate-saving plankton

Noah's Ark flood spurred European farming
November 17, 2007 07:19 PM - Reuters
LONDON (Reuters) - An ancient flood some say could be the origin of the story of Noah's Ark may have helped the spread of agriculture in Europe 8,300 years ago by scattering the continent's earliest farmers, researchers said on Sunday.
Using radiocarbon dating and archaeological evidence, a British team showed the collapse of the North American ice sheet, which raised global sea levels by as much as 1.4 meters, displaced tens of thousands of people in southeastern Europe who carried farming skills to their new homes.The researchers said in the journal Qua

Black Sea to take years to recover from oil spill
November 16, 2007 08:31 AM - WWF -Climate Change
Moscow, Russia – The oil spill that wreaked havoc in the Kerch Strait leading to the Black Sea last week will take at least 5 to 10 years for the marine environment to recover, says WWF.According to WWF specialists, the 2000-tonne spill has badly affected the local fishing industry. Fish caught in the Kerch Strait are not safe for consumption.
Conservation Groups Act to Protect Loggerhead Sea Turtle
November 15, 2007 04:48 PM - , Oceana
Washington, D.C., – Conservation groups Oceana and the Center for Biological Diversity petitioned the federal government today to stop the precipitous decline of the western North Atlantic loggerhead sea turtle. The petition urges the National Marine Fisheries Service, the agency responsible for protecting loggerheads in ocean waters, and the U.S. Fish and Wildlife Service, the agency responsible for protecting turtles on land, to change the designation of western North Atlantic loggerheads from “threatened” to “endangered” under the U.S. Endangered Species Act.
U.N. Climate Talks Make Slow Progress
November 15, 2007 04:29 PM - Reuters
VALENCIA, Spain (Reuters) - Delegates at crucial U.N. talks on the causes and effects of global climate change are making slow progress with an agreement still some way off, sources close to the discussions said on Thursday.
"The same governments which are usually hostile to binding emissions reductions, and especially the Kyoto Protocol, are also those who are blocking progress on agreeing to sound science as the basis for future action," said Stephan Singer, a climate expert at the WWF conservation group.
New south Florida nursery to focus on staghorn corals

In response to the need for localized efforts to protect and recover the surviving populations of the threatened staghorn coral, Diego Lirman, Ph.D., and James Herlan, researchers from the University of Miami’s Rosenstiel School of Marine and Atmospheric Science (RSMAS) have established an underwater nursery dedicated to the propagation of staghorn corals.
