Coral reefs are increasingly vulnerable to angry oceans

...storms in coming decades. Other effects of global warming could limit the capacity of the reefs to bounce back from periods of high wave forces, according to the researchers. For example, episodes of unusually hot temperatures can cause corals' cells to become toxic, or bleached. Another problem is overfish...

The first tree genome is published: Poplar holds promise as renewable bioenergy resource

...on of greenhouse gases." "The challenge of global warming requires global solutions," said Martin Godbout, President, Genome Canada. "The international consortium that successfully sequenced the poplar genome provides a model for great minds working together and serves as an example of how discovery science...

Climate experts search for answers in the oceans

...anche explained. "The risk is that we may find the warming of the sea and the modification of the water circulation patterns may cut off or modify some of that primary production, so it is important to know both sea-surface temperature and ocean colour." In order to make the most of all satellite informa...

Shrinking ponds signal warmer, dryer Alaska

...in arctic ponds are associated with recent climate warming in Alaska and may have profound effects on climate... Over the past 50 years, Alaska has experienced a warming climate with longer growing seasons, increased permafrost thawing, an increase in water loss due to ...

Climate change creates dramatic decline in red-winged black bird population

Global warming strikes again. A University of Illinois researcher...that although some people may be in denial, global warming exists. "There are long-term records that show melting glaciers and altered ecological patterns like...

(4) Environmental synergisms, where two or more simultaneous threats—such as habitat fragmentation and wildfires, or logging and over hunting—dramatically increase local extinctions of...

Researchers link ocean organisms with increased cloud cover and potential climate change

... may be partially countering the effects of global warming by reducing the amount of energy the planet absorbs from the sun. Researchers Athanasios Nenes of the Georgia Institute of Technology and Nicholas Meskhidze ?formerly at Georgia Tech but now at North Carolina State University ?reported their findi...

Researchers to study why dead zone returned to Lake Erie

...o the bottom waters. In the third scenario, global warming has caused the layer of bottom water to become thinner, with less oxygen. The dead zone materialized in Erie's central basin and can cover as much as three quarters of the area, Scavia said. It was discovered through routine monitoring of the lake....

Meeting the ethanol challenge: Scientists use supercomputer to target cellulose bottleneck

...r. A convergence of factors from looming global warming to unstable international oil supplies is driving a surge in renewable biofuels such as ethanol, with worldwide ethanol production more than doubling between 2000 and 2005. To date, corn has been the favorite ethanol source. While good news for farme...

Bumblebee house warming -- it takes a village

...know whether the smaller bees are really better at warming the nest, or whether the larger bees avoid incubating for other reasons. In general, larger bumblebee workers are foragers for food and they could be committed to that task. This kind of size-based division of labor might make the colony more effic...

Mosquito genes explain response to climate change

"It affects development, reproduction and dormancy, and this response is occurring in diverse groups of animals from insects to birds and mammals." The chromosomal map ...

Ethanol vehicles pose a significant risk to human health, study finds

...a clean and renewable fuel that will reduce global warming and air pollution,'' said Jacobson, associate professor of civil and environmental engineering. ''But our results show that a high blend of ethanol poses an equal or greater risk to public health than gasoline, which already causes significant health...
