Our best guess about global warming may be wrong
September 2, 2009 06:40 AM - Moises Velasquez-Manoff, The Christian Science Monitor, Environmental Health News

Fifty-five million years ago, the world was a much warmer place. The poles were ice-free year-round. Palm trees grew in Alaska. Forests stretched right into the Arctic Circle. There, swamps like those in today’s southeastern United States hosted alligators, snakes, and giant tortoises. Scientists call this time in Earth’s history the Eocene, the dawn of the age of mammals. And climatologists have naturally taken a keen interest in how it began. They know that a dramatic spike in carbon dioxide associated with rapid climate change kicked off the epoch – called the "Paleocene-Eocene Thermal Maximum" (PETM). But what scientists don’t understand about the PETM may hold the most relevant lessons for where the world’s climate is headed today.

EPA to declare CO2 a dangerous pollutant

Carbon dioxide will soon be declared a dangerous pollutant - a move that could help propel slow-moving climate-change legislation on Capitol Hill, the head of the Environmental Protection Agency said Monday.

Oceans Could Absorb Much More CO2

Earth's oceans are vast reservoirs of carbon dioxide (CO2) with the potential to control the pace of global warming.

10,000 Homes Threatened in Los Angeles FIres

The unstoppable Angeles National Forest fire threatened 10,000 homes Saturday night as it more than tripled in size and chewed through a rapidly widening swath of the Crescenta Valley, where flames closed in on backyards and at least 1,000 homes were ordered evacuated. Sending an ominous plume of smoke above the Los Angeles Basin, the fire was fueled by unrelenting hot weather and dense brush that has not burned in 60 years.

Los Angeles Wildfires Fueled by Heat

Firefighters battling four wildfires around Los Angeles saved hundreds of homes in an affluent coastal community but struggled against a larger fire coming down the mountains toward another exclusive suburb. With temperatures in excess of 100 Fahrenheit (37 Celsius), flames flared above La Canada Flintridge, where nearly 900 homes were under voluntary evacuation, 1,500 acres had burned and containment was zero percent.

Natural Gas: "Bridge Fuel" or Renewable Energy Killer?
August 28, 2009 11:28 AM - BC Upham, Triple Pundit

Natural gas is often portrayed as a "bridge fuel," providing a lower-carbon alternative to coal while zero-carbon technologies, wind and solar primarily, scale up capacity and, hopefully, lower their price. In the long term this may be accurate, but in the short term there’s a different possibility: that cheap natural gas will stymie growth in wind and solar by providing a “second best” solution to meeting green house gas reduction benchmarks.

Nitrous oxide fingered as monster ozone slayer
August 28, 2009 11:14 AM - Janet Raloff, Science News

New calculations indicate that nitrous oxide has risen to become the leading threat to the future integrity of stratospheric ozone, Earth’s protective shield against the sun’s harmful ultraviolet rays.

EPA Awards $20 Million in Recovery Act Funding for Clean Diesel Finance Program
August 28, 2009 11:05 AM - EPA

The U.S. Environmental Protection Agency announced three recovery act grants totaling $20 million in funding for the SmartWay Clean Diesel Finance Program. These recovery act grants will fund the purchase of new, cleaner or retrofitted vehicles and equipment, protecting air quality and creating and retaining jobs in three communities across the country.
