Scientists have long debated about the impact on global climate of water evaporated from vegetation. New research from Carnegie's Global Ecology department concludes that evaporated water helps cool the earth as a whole, not just the local area of evaporation, demonstrating that evaporation of water from trees and lakes could have a cooling effect on the entire atmosphere.
Alternative fuel sources for cars may have a glowing future as a Kansas State University (K-State) graduate student is working to replace petroleum fuels with ones made from sunlight.
California beach towns could face hefty economic losses caused by sea level rise in the next century, according to a new state-commissioned study.
They expressed concerns ranging from safety, such as unpredictable weather patterns and dangerous ice conditions, to changes in plants and animals as well as decreased availability of firewood.
La Niña, which contributed to extreme weather around the globe during the first half of 2011, has re-emerged in the tropical Pacific Ocean and is forecast to gradually strengthen and continue into winter.
Boston University researchers have estimated that even if international efforts to limit temperature increases to 2 degrees Celcius, mean global temperatures will continue to be extreme.
Trees can reveal key information about fire events, and some trees have a lot to tell — one tree researchers examined endured 14 separate fires through its lifetime.
A pilot waste-to-energy system recently constructed by Duke University and Duke Energy garnered the endorsement of Google Inc., which invests in high-quality carbon offsets from across the nation to fulfill its own carbon neutrality goals.
Although the burning of natural gas emits far less carbon dioxide than coal, a new study concludes that a greater reliance on natural gas would fail to significantly slow down climate change. The study appears this week in the Springer journal Climatic Change Letters.
The percent of land area experiencing exceptional drought reached record levels in August in three U.S. states – Texas, Oklahoma and Kansas – amid new concerns about how long the conditions may persist, an official with the National Drought Mitigation Center at the University of Nebraska-Lincoln said.
Recent heavy rain and flooding has increased the danger of landslides on moderate to steep slopes, according to scientists in the Bureau of Topographic and Geologic Survey in the Department of Conservation and Natural Resources (DCNR).
The far-reaching field project, known as HIPPO, is enabling researchers to generate the first detailed mapping of the global distribution of gases and particles that affect Earth’s climate.
Clouds only amplify climate change, says a Texas A&M University professor in a study that rebuts recent claims that clouds are actually the root cause of climate change.
Measuring the emission of greenhouse gases from croplands should take into account the crops themselves, according to new research.
An earthquake and a hurricane, all in the same week, on the same coast. Are they related?
The earth is warming up due to rising carbon dioxide concentrations in the atmosphere. NWO-funded researchers have discovered that the increase in carbon dioxide can reduce the nuisance caused by toxic blue algae, a bacterium commonly found in swimming water throughout the Netherlands in the summer
With citizens’ groups seeking government regulation of foul-smelling ammonia emissions from large dairy farms, scientists reported that adding natural plant extracts to cow feed can reduce levels of the gas by one-third while reducing the need to fortify cow feed with expensive protein supplements.
Scientists in France have discovered that honeybees are at a higher risk of dying from infection by Nosema ceranae (N. ceranae) when they are exposed to low doses of insecticides
Details are now emerging about a microbial metabolic pathway that helps solve the mystery of how certain bacteria capture carbon in the dark ocean, enabling a better understanding of what happens to the carbon that is fixed in the oceans every year.
A new study of dust-like particles of soot in the air provides fresh evidence that reducing soot emissions from diesel engines and other sources could slow melting of sea ice in the Arctic faster and more economically than any other quick fix, a scientist reported.
