Tipping point already reached?

Two hundred years from now, the planet could look very different. This week two landmark studies revealed that West Antarctica's ice sheet is in a state of seemingly inevitable collapse linked to climate change. The slow-motion collapse would by itself eventually lead to a rise in global levels of 3.6-4.5 meters (12-15 feet), overrunning many of the world's islands, low-lying areas, and coastal cities. The only silver lining is that scientists conservatively estimate that the collapse could take 200-1,000 years. >> Read the Full Article

Go out and play!

New research confirms the health benefits associated with outdoor play for children. New research from the University of Bristol shows that while most children spend the largest amount of their after-school time indoors either alone or with their parents, hours spent outdoors with friends has the greatest positive affect on a child's level of physical activity. The correlation works out like this: children get an extra 17 minutes of physical activity for every hour of time spent outdoors. >> Read the Full Article

Overwhelming the Mississippi

New evidence from University of Texas at Austin researchers posit that the great Mississippi's natural ability to chemically filter out nitrates is being overwhelmed. UT's hydrologists demonstrate the enormity of the filtering process for almost every drop of water that enters into the 311,000-mile long course ending in the Gulf of Mexico. >> Read the Full Article

Carbon Dioxide pushing weather around in the southern hemisphere

So why is Antarctica is not warming as much as other continents, and why are there more droughts in southern Australia? According to new Antarctic ice core research published in Nature Climate Change, rising levels of carbon dioxide in the atmosphere are intensifying the Southern Ocean winds, which are known to deliver rain to southern Australia, but instead they are pushing them further south towards Antarctica. >> Read the Full Article

Bee booby-traps defend African farms from elephants

Wire fences booby-trapped with beehives are being built in five African countries to prevent elephants from raiding farms, while also providing local people with honey. 'Beehive fences' are now being put up in Botswana, Mozambique, Tanzania and Uganda by UK charity Save the Elephant, says Lucy King, leader of the Elephants and Bees Project in Kenya — and they are already in use at three communities in Kenya. >> Read the Full Article

Coral Reefs: Who's protecting whom?

According to a recent study, delicate coral reefs are protecting hundreds of millions of people around the world from stronger storms, rising seas, and flooding. The internationally supported study finds that coral reefs reduce the wave energy that would otherwise impact coastlines by 97 percent. >> Read the Full Article

India, not China, has the world's worst urban air pollution

Breathing in urban India is hard: of the world's top twenty cities with the worst air, 13 of them are found in India, according to a new analysis by the World Health Organization (WHO). Despite the attention recently given to Chinese cities for atrocious air pollution, many of India's cities are actually worse when comparing annual averages of fine airborne particulates. >> Read the Full Article
