EPA proposes crackdown on fracking air pollution

Business Green: EPA proposes crackdown on fracking air pollution Agency delays smog rules, but moves to tackle oil and gas industry air pollution The US Environmental Protection Agency (EPA) has unveiled plans to crackdown on air pollution from controversial "fracking" projects, having previously angered green groups by delaying new regulations to tackle smog. The agency yesterday set out proposals designed to tackle air pollution from oil and gas wells and, in particular, hydraulic fracturing or "fracking"...

Fire Made Arctic Spew, Rather Than Absorb, Carbon

National Public Radio: The Arctic tundra has been relatively thunderstorm-free for 10,000 years. But conditions are changing in the far north, and in 2007 a lightning strike caused the biggest wildfire ever recorded on the North Slope of Alaska. The tundra is normally a carbon sink, but scientists report in the journal Nature that that single fire released more carbon into the atmosphere than the entire Arctic tundra absorbs every year.

Ignored Tundra Fires Could Have Impact on Global Warming: Study

IBTimes: Stay connected with cutting edge technology news Sample The fire covered more than 400 square miles on the North Slope of Alaska's Brooks Range and 2.1 million metric tons of carbon was released in the fire. It was twice the size the amount of greenhouse gases generated by Miami in one year. The fire not only inserted greenhouse gases into the atmosphere but it also consumed 30 percent up of the insulating layer of the organic matter that protects moss covered landscape. Arctic tundra stores...

World’s biggest refugee camp extended as Somalis flood in

Reuters: Thousands of Somalis fleeing drought, famine and war have started moving into a new extension of the world's largest refugee camp in Kenya, which is increasingly concerned about bearing the brunt of the Horn of Africa crisis. About 1,500 Somali refugees are now crossing into Kenya each day but there is no room for them in the congested Dadaab camp, which was declared full in 2008. Instead, 65,000 refugees have been forced to "self-settle" in cardboard and plastic shelters on flood-prone land...

Protected areas “insufficient” to stem biodiversity loss

Business Green: Designating increasing amounts of land and sea as protected areas has failed to halt a "steep decline" in biodiversity, leaving an urgent reduction in man's ecological footprint as the only option for preserving the natural environment. That is the conclusion of a new study published yesterday in the Marine Ecology Progress Series journal, which calculates that levels of consumption and population growth mean we will need the productivity of up to 27 Earths by 2050 in order to halt recent declines...

Native grasses in California under threat

United Press International: Native grasses in California, already threatened by invasive exotic varieties, are likely to be pushed aside even more as the climate warms, researchers say. Researchers at the University of California, Berkeley, have mapped the ranges of all 258 native grasses and 177 exotic grasses in the state and estimated how they would be affected by increased temperatures and decreased rainfall expected with climate change. Many of the characteristics that make exotic grasses more successful than many...

Food Insecurity Caused by Climate Change Affects Family Planning in Kenya

Global Press Institute: Food Insecurity Caused by Climate Change Affects Family Planning in Kenya Experts and mothers say climate change is directly and indirectly affecting childbearing in Kenya. They say food insecurity caused by climate change hurts pregnant mothers’ and children’s health and is leading Kenyans to opt for smaller families. It is early evening, and one of the fast food outlets in the South C Shopping Center in Nairobi, Kenya’s capital, is bustling with activity as hungry souls troop in one after the...

Ongoing Global Biodiversity Loss Unstoppable With Protected Areas Alone

redOrbit: Posted on: Thursday, 28 July 2011, 18:06 CDT Biodiversity loss is underestimated as the ability of protected areas to address the problem is overestimated Continued reliance on a strategy of setting aside land and marine territories as "protected areas" is insufficient to stem global biodiversity loss, according to a comprehensive assessment published today in the journal Marine Ecology Progress Series. Despite impressively rapid growth of protected land and marine areas worldwide - today...
