Wildfire—It’s Not Spreading Like Wildfire

A new analysis of global data related to wildfire, published by the Royal Society, reveals major misconceptions about wildfire and its social and economic impacts. Prof. Stefan Doerr and Dr Cristina Santin from Swansea University’s College of Science carried out detailed analysis of global and regional data on fire occurrence, severity and its impacts on

Chemical Emitted by Trees Can Impact St. Louis’ Ozone Levels

It is well known that the dog days of summer in St. Louis are hot, humid and hazy. On the warmest of these days, the air arrives from the south, bringing with it high temperatures, moisture and natural forest emissions of chemicals, known as hydrocarbons, from the Ozark Plateau. The hydrocarbons can interact with human-influenced

Increased Vegetation in the Arctic Region May Counteract Global Warming

Climate change creates more shrub vegetation in barren, arctic ecosystems. A study at Lund University in Sweden shows that organisms, such as bacteria and fungi, are triggered to break down particularly nutritious dead parts of shrubbery. Meanwhile, the total amount of decomposition is reducing. This could have an inhibiting effect on global warming. A large

Satellite Readings Show Methane and Carbon Dioxide on the Rise

Satellite readings show that atmospheric methane and carbon dioxide are continuing to increase despite global efforts to reduce emissions. Methane concentrations were somewhat constant until 2007, but since then have increased at about 0.3% per year, whereas global carbon dioxide levels continue to rise at about 0.5% per year. The results, presented this week at

Wildfires to Increase in Alaska with Future Climate Change

MISSOULA—Climate change is melting glaciers, reducing sea-ice cover and increasing wildlife activity – with some of the most dramatic impacts occurring in the northern high latitudes. New research by University of Montana affiliate scientist Adam Young and UM fire ecology Associate Professor Philip Higuera projects an increased probability of fires occurring in Alaskan boreal forest

Highway Noise Deters Communication Between Birds

GAINESVILLE, Fla.—New research from University of Florida Institute of Food and Agricultural Sciences researchers shows birds may be avoiding habitats near noisy highways because they can’t hear fellow birds’ alarms that warn them of attacking hawks or owls. Some highways cut through or run along natural areas, and researchers know that wild birds often make

Cities Hold the Key to a Livable Future

Washington, D.C.—Today, nearly 3.9 billion people–half of the world’s population–live in urban areas. By 2050 that number is expected to nearly double. According to Can a City Be Sustainable? (State of the World), the latest edition of the annual series from the Worldwatch Institute, there is no question cities will continue to grow; the only

Study Finds Ice Isn’t Being Lost from Greenland’s Interior

Scientists studying data from the top of the Greenland ice sheet have discovered that during winter in the center of the world’s largest island, temperature inversions and other low-level atmospheric phenomena effectively isolate the ice surface from the atmosphere — recycling water vapor and halting the loss or gain of ice. A team of climate

Better Integration of Land Use Impacts Needed Across EU Policies

Land is a valuable and limited resource. The environmental impact of land used for building new roads, houses or energy grids should be better integrated into European Union policies, according to a report released today by the European Environment Agency. A preliminary review on how land is used in the EU found that more attention

Ice Loss Accelerating in Greenland’s Coastal Glaciers

HANOVER, N.H. – Surface meltwater draining through and underneath Greenland’s tidewater glaciers is accelerating their loss of ice mass, according to a Dartmouth study that sheds light on the relationship between meltwater and subglacial discharge. The findings appear in the journal Annals of Glaciology. A PDF is available on request. Greenland has the potential to
