Extent of Peruvian Amazon lost to illegal goldmines mapped first time

Guardian: The area affected by illegal gold mining in Peru's south-eastern Amazon region increased by 400% from 1999 to 2012, according to researchers using state-of-the-art mapping technology. Using airborne mapping and high-satellite monitoring, researchers led by the Carnegie Institution for Science also showed that the rate of forest loss in Madre de Dios has tripled since the 2008 global economic crisis, when the international price of gold began to rise to new highs. Until this study, thousands...
North Sea data reveals extent of oil and gas pollution
2013-10-22 01:00:00| Offshore Technology
Mandatory reported data has revealed there are up to sixty spills a month happening in the North Sea alone. This disputes the industry's claim it is environmentally safe and not a chronic polluter. But what is the real danger of these small but chron
Arctic Sea Ice Extent Doubles from Last Year, Still 6th Lowest on Record

Nature World News: Sea ice in the Arctic Ocean recouped from last summer's record low levels, with the amount of ice surviving this summer nearly 50 percent more than in 2012, scientists said Friday. Still, the extent of the Arctic sea was the sixth lowest ever recorded. Compared to the 1981-2010 average, this summer's sea ice minimum -- a reflection of the maximum ice melting in the warm season -- was 432,000 square miles (1.12 million square kilometers) lower than the average, according to data presented by the...
Arctic sea ice "recovers" to its 6th-lowest extent in millennia
2013-09-19 05:58:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: As Suzanne Goldenberg reported in The Guardian yesterday, Arctic sea ice appears to have reached its annual minimum extent, at approximately 5.1 million square kilometers. This is the 6th-lowest extent since the satellite record began in 1979. But in fact, scientists have also reconstructed Arctic sea ice extent data much further into the past. For example, Drs. Walsh & Chapman from the University of Illinois have estimated sea ice extent as far back as the year 1870 using a vast array of data...
Full Extent of Heavy Metal Contamination in Exxon Oil Spill Still Unknown
2013-07-15 10:00:00| Climate Ark Climate Change & Global Warming Newsfeed
InsideClimate: When a broken pipeline spills oil into a residential neighborhood, the most immediate health concerns are those caused by volatile chemicalsairborne toxins that leave people complaining of symptoms like headaches and nausea and worrying about long-term problems like cancer. But crude oil also contains small amounts of heavy metals that rarely evaporate into the air. Instead, they stay with the oil as it spills onto the ground and into waterways. These compounds, which include mercury, manganese,...
