GLOBAL WARMING - A THREAT TO CORAL REEFS IN GULF OF MANNAR: The coral reef wealth of the Gulf of Mannar, which is being conserved through joint efforts of various governmental, non-governmental and research agencies, is now facing a different kind of threat — global warming and consequent climate change.
Coral reefs, known as rain forests of the sea, are a source of food security and livelihood options for hundreds of millions people, coastal defence and tourist hotspots. The Gulf of Mannar (GoM) is one of the four important coral reefs in India and thousands of artisanal fisher folk are dependant on fishery resources from this reef area.

CLIMATE CHANGE MAY CAUSE KIDNEY STONES: Climate change, it turns out, has a few side effects. High temperatures make it harder for the body to cool itself, which can cause heat cramps, exhaustion, and stroke--a particular concern for people with heart conditions. Heat also affects air quality, as stagnant air leads to higher smog concentrations, which in turn places stress on those with respiratory conditions like asthma. Higher levels of carbon dioxide will likely cause pollens to proliferate, while increased humidity will nurture fungal growth--two major aggravators of asthma and allergies. Hotter weather will also lead to the spread of disease. Mosquitoes carrying diseases like malaria, West Nile virus, and dengue fever will migrate into new areas of the US. So will ticks bearing Lyme disease. Water- and food-borne pathogens also thrive in balmier climes.

HARSH WINTER DOESN'T MEAN LESS WARMING: German climate experts say the past harsh winter in Europe and North America does not indicate a slowing of global warming. The German Meteorological Service said Tuesday while the history of climate change shows ups and downs, the overall rise in temperatures is evident.

FIXING THE OIL SPILL - DUMP INTO GULF OF MEXICO: BP and the U.S. Coast Guard are dumping large amounts of "dispersants" both on the surface and underwater, in a desperate attempt to control the ongoing spill. Dispersants are surfactants, not unlike what you use on your dishes, that break oil down into small droplets that sink into the water. . How much are they dumping? Lots. According to ProPublica, "BP has already bought up more than a third of the world's supply" of dispersants. On Thursday alone, ProPublica reports, emergency workers dropped 100,000 gallons of the stuff into the Gulf.

BURNING OIL SENDS TOXIC SMOKE TOWARDS GULF OF MEXICO: The EPA is warning that Gulf Coast residents are at risk of headaches, nausea, and other ill health effects; the culprit is air pollution from the oil burns that response teams are conducting to try to keep the big slick away from coastlines. "The BP Oil Spill in the Gulf could cause an odor similar to that of a gas station for communities along the affected coast," warns the site the EPA set up on the disaster

NOW GOOGLE INVESTS IN 2 WIND FARMS: Google Inc. has invested $38.8 million in two North Dakota wind farms, the Internet giant's first direct investment in utility-scale renewable energy generation. The Mountain View, Calif., company said in a Monday blog post that it invested in wind farms built by NextEra Energy Resources, a unit of FPL Group Inc. The wind turbines, made by General Electric Co., generate 169.5 megawatts of power, enough to serve more than 55,000 homes.
