Comet impact theory disproved
New data, published today, disproves the recent theory that a large comet exploded over North America 12,900 years ago, causing a shock wave that travelled across North America at hundreds of kilometres per hour and triggering continent-wide wildfires. view more (2009-01-27)
More large forest fires linked to climate change
Large forest fires have occurred more frequently in the western United States since the mid-1980s as spring temperatures increased, mountain snows melted earlier and summers got hotter, according to new research. view more (2006-07-07)
Fire is important part of global climate change, report scientists
Fire must be accounted for as an integral part of climate change, according to 22 authors of an article published in the April 24 issue of the journal Science. The authors determined that intentional deforestation fires alone contribute up to one-fifth of the human-caused increase in emissions of carbon dioxide, a heat-trapping gas that raises... view more...

Time to burn: Getting a step ahead of wildland arsonists
Over 1.5 million fires are set by arsonists each year in the United States, resulting in over $3 billion in damages. view more (2005-09-29)
Transcontinental wildfire emissions monitored from space
Using data from the SCIAMACHY instrument aboard ESA's environmental satellite Envisat, scientists have determined that the carbon monoxide hovering over Australia during the wildfire season largely originated from South American wildfires some 13 000 kilometres away. view more (2007-05-09)
Forest fires a huge cost to health
Forest fires don't just have an impact on the environment, but on human health, according to a new study from the University of Alberta in Edmonton, Canada,which attempted to put a pricetag on the actual economic losses caused by one such fire. view more (2006-08-11)
Coastal retreat in face of rising sea levels found to be influenced by wildfires
The retreat of coastlines due to rising sea levels may be accelerated by wildfires, a Duke University researcher has discovered. view more (2005-10-18)
Extraterrestrial Impact Likely Source of Sudden Ice Age Extinctions
At the end of the Pleistocene era, wooly mammoths roamed North America along with a cast of fantastic creatures - giant sloths, saber-toothed cats, camels, lions, tapirs and the incredible teratorn, a condor with a 16-foot wingspan. view more (2007-09-25)
Climate change to spur rapid shifts in wildfire hotspots
Climate change will bring about major shifts in worldwide fire patterns, and those changes are coming fast. view more (2009-04-08)
Scientists Estimate Mercury Emissions from U.S. Fires; West Coast and Southeastern States are Major Emitters
Forest fires and other blazes in the United States likely release about 30 percent as much mercury as the nation's industrial sources, according to initial estimates in a new study by scientists at the National Center for Atmospheric Research (NCAR). view more (2007-10-18)
Disease-impact models may rely on incorrect assumptions
Even when we know how a disease affects individual animals, it is challenging to predict what impact it will have on the whole population, and yet predicting how disease affects a population is a primary concern for wildlife conservation and even public health. view more (2006-04-13)
Cosmic bogs @ the London Catastrophes conference
You may think that peat bogs are among the least interesting places on Earth and you could be right. But according to speakers at Brunel University`s `Environmental Catastrophes` conference, that doesn`t stop them being excellent recorders of catastrophic environmental events like volcanic eruptions and cosmic influx. According to Dr Lars... view more... (2002-08-17)
What if New Mexico doesn't address climate change?
If nothing is done to reduce greenhouse gas emissions, New Mexico could experience some $3.2 billion in associated costs -- led primarily by wildfires and health-care. This could translate to an individual tab of about 8 percent of annual household income by 2020, according to a report produced for the University of Oregon's Climate Leadership... view more...

Models play important role in understanding extreme weather
Weather is a hot topic here in Interior Alaska and a quick way to get anyone talking. Not a day goes by in winter months without some observations of temperatures, air inversions, or even a mention that the sun budged another degree above the horizon. view more (2007-03-29)
Why California should consider Australia's 'prepare, stay and defend' wildfire policy
Even as debate rages over the safety of Australia's "Prepare, stay and defend, or leave early" policy of wildfire defense, fire researchers at the University of California, Berkeley, and in Australia say that the strategy is worth consideration in California and other regions in the United States. view more (2009-02-26)
Fires fuel mercury emissions, U-M study finds
Forest fires release more mercury into the atmosphere than previously recognized, a multidisciplinary research project at the University of Michigan suggests. view more (2007-01-10)
Burning wetlands unleash sequestered mercury in wake of climate change
Climate change appears to be contributing to the waking of a dangerous sleeping giant in the most northern wetlands of North America - mercury. view more (2006-08-22)
First-ever 'State of the Carbon Cycle Report' finds troubling imbalance
The first "State of the Carbon Cycle Report" for North America, released online this week by the U.S. Climate Change Science Program, finds the continent's carbon budget increasingly overwhelmed by human-caused emissions. view more (2007-11-15)
Communications team erects lifeline for firefighters battling California wildfires
Early Sunday morning, July 23, an abandoned campfire in Cleveland National Forest erupted into a 7,000-acre wildfire that continues to spread. Now known as the Horse Fire, it threatens more than 1,500 homes and 100 commercial properties near San Diego, Calif. view more (2006-07-27)
