In the years after Columbus' voyage, burning of New World forests and fields diminished significantly – a phenomenon some have attributed to decimation of native populations by European diseases. But a new University of Utah-led study suggests global cooling resulted in fewer fires because both preceded Columbus in many regions worldwide.
Adam M. Fasano, CIH has been promoted to Principal at GZA GeoEnvironmental’s Norwood, MA office. GZA is an environmental and geotechnical consulting firm.
For decades, scientists have known that the effects of global climate change could have a potentially devastating impact across the globe, but Harvard researchers say there is now evidence that it may also have a dramatic impact on public health.
Researchers have found a way to use GPS to measure short-term changes in the rate of ice loss on Greenland -- and reveal a surprising link between the ice and the atmosphere above it.
Today, the U.S. Environmental Protection Agency’s (EPA) Energy Star program launched the 2012 National Building Competition: Battle of the Buildings with a record 3,200 buildings across the country going head to head to improve energy efficiency, lower utility costs and protect health and the environment.
For several days this month, Greenland's surface ice cover melted over a larger area than at any time in more than 30 years of satellite observations.
The greatest climate change the world has seen in the last 100,000 years was the transition from the ice age to the warm interglacial period.
Sulfur has traditionally been portrayed as a secondary factor in regulating atmospheric oxygen, with most of the heavy lifting done by carbon. However, new findings that appeared this week in Science suggest that sulfur's role may have been underestimated.
Global emissions of carbon dioxide (CO2) -- the main cause of global warming -- increased by 3% last year, reaching an all-time high of 34 billion tonnes in 2011.
Scientists from the University of Toronto and the University of California Santa Cruz are shedding light on one potential cause of the cooling trend of the past 45 million years that has everything to do with the chemistry of the world's oceans.
“The first half of 2012 was dry for most of the Northeast. New York, Massachusetts, Pennsylvania, New Jersey, and West Virginia were below normal. Maryland and Connecticut were much below normal, and Delaware had its driest on record.
Until now, scientists who study air pollution using satellite imagery have been limited by weather. Clouds, in particular, provide much less information than a sunny day.
No matter how you drill it, using natural gas as an energy source is a smart move in the battle against global climate change and a good transition step on the road toward low-carbon energy from wind, solar and nuclear power.
Elevated levels of atmospheric carbon dioxide accelerate carbon cycling and soil carbon loss in forests, new research led by an Indiana University biologist has found.
Satellite measurements show that nitrogen dioxide in the lower atmosphere over parts of Europe and the US has fallen over the past decade.
An international team that includes scientists from Johannes Gutenberg University Mainz (JGU) has published a reconstruction of the climate in northern Europe over the last 2,000 years based on the information provided by tree-rings.
Studies by U.S. Department of Agriculture (USDA) scientists show some no-till management systems can lower atmospheric levels of PM10—soil particles and other material 10 microns or less in diameter that degrade air quality—that are eroded from crop fields via the wind.
A new study led by the University of Colorado Boulder indicates air pollution in the form of nitrogen compounds emanating from power plants, automobiles and agriculture is changing the alpine vegetation in Rocky Mountain National Park.
The U.S. Environmental Protection Agency is proposing to approve Arizona’s air quality plan to control sulfur dioxide and soot at three power plants in the state.
Some coral reef fish may be better prepared to cope with rising CO2 in the world's oceans -- thanks to their parents.
