In the virtual worlds of climate modeling, forests and other vegetation are assumed to bounce back quickly from extreme drought. But that assumption is far off the mark, according to a new study of drought impacts at forest sites worldwide. Living trees took an average of two to four years to recover and resume normal growth rates after droughts ended, researchers report today in the journal Science.

Making Tastier Wines with Fewer Pesticides
Wine-making is steeped in age-old traditions, but to address the threat of pests and concerns over heavy pesticide use, vintners are turning to science. With the goal of designing better grape breeds, scientists are parsing the differences between wild American grapes — which make terrible wine but are pest-resistant — and the less hardy grape species pressed for fine wines worldwide. They report their findings in ACS’ Journal of Agricultural and Food Chemistry.
Offshore Wind Power Comes to the US
The United States marked an energy milestone this week as construction began on a pilot offshore wind program that will be used to test the economic feasibility of offshore wind energy. According to the Bureau of Energy, some four million megawatts of power lie in wait off the coasts and the shores of regions like the Great Lakes, where wind blusters far stronger than it does on land — and even a few miles an hour makes a big difference with turbines.
Los manglares ayudan a proteger contra el aumento del nivel del mar
Los manglares podrían desempeñar un papel crucial en la protección de las zonas costeras contra la subida del nivel del mar causado por el cambio climático, según una nueva investigación de la Universidad de Southampton.
Un estudio conjunto de investigadores de la Universidad de Southampton, junto con colegas de las universidades de Auckland y Waikato en Nueva Zelanda, utilizó avanzadas simulaciones matemáticas para estudiar cómo los bosques de manglares responden a los niveles del mar elevados.
Fort Knox Military Base establishes Indiana Bat Management Area
Fort Knox, a U.S. military installation located near Louisville, Kentucky, and famous for storing the nation’s gold bullion, has two of the largest known maternity colonies of federally endangered Indiana bats within the range of the species and the largest in Kentucky. On the same night, officials documented 451 and 478 Indiana bats emerging from two separate trees, both are records for this species. The first maternity colony of Indiana bats on Fort Knox (approximately 150 individuals) was discovered in 1999. The total number of Indiana bats in existence has declined due to white-nose syndrome, a devastating wildlife disease; a reduction and contamination of their insect food supply due to pesticide usage and disturbances by humans during the bats’ winter hibernation in caves and mines. During hibernation, bats cluster in groups of up to 500 per square foot, which means a single event can destroy a large number of bats.
Not all whaling is the same
The Faroe Islands' annual 'grindadráp', in which hundreds of pilot whales are slaughtered with knives and hooks, is a horrifying spectacle, writes David Lusseau. But unlike industrial whaling it poses no threat to the species. And is it really any worse than the industrial factory farming that we routinely ignore?
Anyone that signs a petition to stop the Faroese grindadráp only to go home and roast a chicken that never saw daylight or moved much when it was reared is a hypocrite.
In the mid-20th century pilot whaling still took place in many north Atlantic nations such as the US and Canada.
