Thanks To The Clean Air Act, We Breathe 3 Million Fewer Tons Of Toxins Each YearLast Updated on 2014-08-22 10:46:19Actions taken by the Environmental Protection Agency under the Clean Air Act have caused U.S. toxic air emissions to drop “significantly” — in some cases by more than half — since the law was amended in 1990, the regulatory agency told Congress in a report Thursday.

Hot and Getting Hotter: Heat Islands Cooking U.S. CitiesLast Updated on 2014-08-22 10:31:21Cities are almost always hotter than the surrounding rural area but global warming takes that heat and makes it worse. In the future, this combination of urbanization and climate change could raise urban temperatures to levels that threaten human health, strain energy resources, and compromise economic productivity.

Global warming slowdown 'could last another decade'Last Updated on 2014-08-22 10:09:01The hiatus in the rise in global temperatures could last for another 10 years, according to new research.
Scientists have struggled to explain the so-called pause that began in 1999, despite ever increasing levels of CO2 in the atmosphere. Read more here
Earth sliding into ‘ecological debt’ earlier and earlier, campaigners warnLast Updated on 2014-08-20 11:56:47
Humans have used up the natural resources the world can supply in a year in less than eight months, campaigners have warned.
The world has now reached “Earth overshoot day”, the point in the year when humans have exhausted supplies such as land, trees and fish and outstripped the planet’s annual capacity to absorb waste products including carbon dioxide. CLICK HERE TO READ MORE.
Here’s How Arctic Sea Ice Could Shrink Even MoreLast Updated on 2014-08-20 11:49:26As the sea ice covering the Arctic continues to shrink under the influence of greenhouse gas-induced warming, it’s causing a host of other changes in the region, including the growth of large waves in the previously iced-over areas. Those waves could potentially reinforce and hasten the demise of sea ice, leading to further changes in the fragile polar realm.
Changes brought on by global warming in the Arctic region have been well documented. Temperatures there have risen twice as fast as the global average. That rise is tied to a decline in Arctic sea ice, which has seen its seasonal minimum area shrink by nearly 14 percent per decade since the late 1970s. Those changes could be influencing weather patterns in lower latitudes of the world, though that’s an area of continuing research for scientists.
