More Extreme Weather In The Arctic Regions
February 5, 2009 10:55 AM - University of Bergen
A new study published in Climate Dynamics by Erik Kolstad and Thomas J. Bracegirdle reveals that one of the most visible signs of climate change is the dramatically reduced ice cover in the Arctic. The retreat of the sea ice leads to rapid changes in the weather conditions in these areas. The study reveals that regions that have been covered by sea ice until now will be exposed to new kinds of severe weather. This may have dire consequences for human activities in the Northern regions.
US states may regain control of vehicle emissions
February 5, 2009 09:23 AM - New Scientist
PRESIDENT Barack Obama is cleaning up after George W. Bush. Within a week of taking office, Obama ordered the US Environmental Protection Agency (EPA) to reconsider Bush's policy of banning states from implementing their own standards for tailpipe emissions.
Insecticide chemical is a powerful greenhouse gas.
February 2, 2009 09:37 AM - The Environment Report
The federal government is going to take some significant steps to reduce global warming gases. Carbon dioxide is the main target, but there are other types of greenhouse gases. Lester Graham spoke with one researcher who found a potent greenhouse gas lingers in the atmosphere much longer than previously thought:
Growing Optimism for U.S. Climate Change Bill
February 2, 2009 08:59 AM - WorldWatch Institute
A new Congress began less than one month ago, yet early indications suggest that 2009 may yield the most dramatic policy response to climate change in U.S. history. The challenge of passing domestic climate legislation before U.S. negotiators participate in global climate talks in Copenhagen, Denmark, in December remains difficult. Economic recession, a health care overhaul, and two foreign wars will compete with climate change for political attention.
Freezers produce 25% of supermarkets' carbon footprint
February 2, 2009 08:55 AM - The Herald
Supermarket fridges and freezers are environmentally unfriendly, spewing out bad gases that make up more than a quarter of the companies' total carbon footprint. The HFCs (hydrochlorofluorocarbons) can have as much as 4000 times more impact on global warming than carbon dioxide, say green campaigners. None of the 10 high-street stores fared well in a survey that had Iceland scoring an alarming -1 out of a hundred, closely followed by rivals Lidl (0 points) and Aldi (+1).
Carmakers fear emission plan could ruin recovery
February 2, 2009 08:53 AM - signonsandiego.com
SACRAMENTO — When President Barack Obama moved to increase gas mileage and curb tailpipe emissions last week, the leaders of the battle against global warming rejoiced. But his directives could steer automakers and the buying public down a bumpy road.
Gore to Lobby Lawmakers on Climate Change
January 30, 2009 09:34 AM - Organic Consumers Association
WASHINGTON (CNN) - Suggesting the planet will soon reach an irreversible "tipping point" of damage to the climate, former Vice President Al Gore plans to tell members of Congress on Wednesday that the U.S. needs to join international talks on a treaty. "This treaty must be negotiated this year," he plans to say, according to a copy of remarks prepared for testimony.
Some Of Earth's Climate Troubles Should Face Burial At Sea, Scientists Say
January 29, 2009 11:10 AM - ScienceDaily
Making bales with 30 percent of global crop residues — the stalks and such left after harvesting — and then sinking the bales into the deep ocean could reduce the build up of global carbon dioxide in the atmosphere by up to 15 percent a year, according to just published calculations.
Capturing Carbon Emissions in Cement?
January 28, 2009 09:40 AM - WorldWatch Institute
The versatile construction ingredient has been commonplace since the Roman Empire, but production has boomed in recent decades, rising nearly 400 percent since 1970. Global cement output may reach 5 billion metric tons by 2030, driven mainly by growth in the top two producing countries, China and India, according to a December WWF report. In much of the world, replacing traditional wooden or earthen structures with concrete - the hardened mix of the cement powder, aggregate, and water - is a sign of wealth and prosperity. But cement manufacture is among the most energy-consuming and polluting industrial processes.
Britain's big polluters accused of abusing EU's carbon trading scheme
January 28, 2009 09:38 AM - The Guardian
Britain's biggest polluting companies are abusing a European emissions trading scheme (ETS) designed to tackle global warming by cashing in their carbon credits in order to bolster ailing balance sheets. The sell-off has helped trigger a collapse in the price of carbon, making it cheaper to burn high-carbon fossil fuels and leading to a fall in the number of clean energy projects. The moves were seized on byenvironmentalists and other critics who have previously criticised theEuropean Union's ETS for delivering more windfall profits for business than climate change.
