Nine nations and the European Union have reached a deal to place the central Arctic Ocean (CAO) off-limits to commercial fishers for at least the next 16 years. The pact, announced yesterday, will give scientists time to understand the region’s marine ecology—and the potential impacts of climate change—before fishing becomes widespread.
Scientists are trying to protect seven marine areas before climate change worsens
The Arctic Ocean may look inhospitable, but it teems with life along its coasts and within the unexpected, ice-free oases brimming with seabirds gorging on plankton and krill. Despite the anchor these places provide for many of the planet’s
Atmospheric conditions and human actions combined to drive the 1930s megadrought
Farms failed and livestock starved in the central United States during the Dust Bowl drought of the 1930s. The event was not just the region’s worst dry spell in modern memory — it was the worst in North America over the past millennium, researchers report in Geophysical Research Letters.
Model also links avian influenza strains to deadly horse flu.
The virus that caused the 1918 influenza pandemic probably sprang from North American domestic and wild birds, not from the mixing of human and swine viruses. A study published today in Nature reconstructs the origins of influenza A virus and
Nature Ancient ice ages that shaped modern caribou populations may foretell animals’ fate in a warmer world. When ice sheets marched across North America 20,000 years ago during the Last Glacial Maximum, they devoured liveable areas for caribou and isolated them from their Eurasian relatives for thousands of years. Now researchers have evidence that such climatic events have sculpted the genetics of North American caribou, which may make the animals unable to adapt to future climate change. “Although the past … Read more…
