Summer haze has a cooling effect in southeastern United States, says new study

Global warming may include some periods of local cooling, according to a new study by researchers at the University of California, Berkeley. Results from satellite and ground-based sensor data show that sweltering summers can, paradoxically, lead to the temporary formation of a cooling haze in the southeastern United States.

Obama to Tighten Fuel-Economy Standards
May 19, 2009 06:07 AM - Bryan Walsh, TIME

In a landmark decision on climate change and energy, President Barack Obama will announce tough new vehicle gas-mileage standards on Tuesday, the first ever national limits on greenhouse-gas emissions. The new policy, which was worked out between Washington, state governments and the auto industry, will require automakers to meet a minimum fuel-efficiency standard of 35.5 miles a gallon by model year 2016 — four years earlier than Congress currently requires.

As Alaska Glaciers Melt, It’s Land That’s Rising
May 18, 2009 06:21 AM - CORNELIA DEAN, The New York Times

Global warming conjures images of rising seas that threaten coastal areas. But in Juneau, as almost nowhere else in the world, climate change is having the opposite effect: As the glaciers here melt, the land is rising, causing the sea to retreat.

Climate Bill CO2 Allocations Strategy
May 16, 2009 10:37 AM - Reuters

The climate change bill moving through the U.S. Congress would initially give away the majority of permits to emit greenhouse gases to entities like electricity distributors and big energy users, such as steel and cement plants, in a cap and trade program.

New Ocean Circulation Experiment has Potential Big Climate Model Impact
May 15, 2009 02:00 PM - Editor, ENN, based on an artilce from eurekalert

New research by Duke University, in conjunction with the Woods Hole Oceanographic Institution is casting doubt on long-held theories of North Atlantic Ocean circulation patterns. This research, supported by the National Science Foundation is important since oceanic circulation is one of the key factors in current atmospheric circulation models, and therefore critical starting points for climate modeling.

What's the Evidence for Climate Change?
May 15, 2009 09:04 AM - LiveScience

Thursday the NSF put out a special report detailing known changes to the planet related to global warming. These are not things that might happen, but things that have.

US and Japan Collaborate on Key Climate Issues
May 14, 2009 04:26 PM - Editor, ENN

A two-day workshop was held this week between the U.S. Environmental Protection Agency (EPA), Japan’s Ministry of Environment (MOEJ) and Japan’s Institute for Global Environmental Strategies to discuss key climate change issues.

Fears of collapse as coral reefs feel the heat

The most spectacular stretch of coral reefs on the planet is in danger of collapse from climate change, overfishing and pollution, according to a report being presented today at the World Oceans Conference in Indonesia.

Document Is Critical of E.P.A. on Clean Air
May 13, 2009 08:56 AM - John M. Broder, New York Times

An internal government memorandum that came to light on Tuesday challenged the scientific and economic basis of a proposed Environmental Protection Agency finding that climate-altering gases are a threat to human health and welfare.

US EPA Outlines Ways to Reduce Our Carbon Footprint
May 13, 2009 06:57 AM - Editor, ENN

The US Environmental Protection Agency has some suggestions on how we can save energy this summer, and reduce our emissions of Green House Gasses. The energy used in an average home costs more than $2,200 a year and contributes more greenhouse gas emissions than a typical car. Looking at the Energy Star ratings on home appliances, cooling equipment, computers and entertainment devices can, collectively, make a large difference.
