Scientists dismiss geo-engineering as a global warming quick fix
2013-01-24 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Smithsonian: Installing a giant mirror in space to block sunlight, dispersing mass quantities of minerals into the oceans to suck carbon dioxide from the air and infusing the Earths upper atmosphere with sun-reflecting chemicals might sound like the stuff of science fiction, but theyre actual techniques that have been contemplated by scientists as possible quick solutions to climate change. More specifically, theyre examples of geo-engineering, a hotly contested subset of climate science whereby the Earths...

Miss Piggy's Version Of Global Warming: What About Me?
2013-01-19 11:54:00| Climate Ark Climate Change & Global Warming Newsfeed
National Public Radio: Here's a new, sly, (and frankly selfish) way to think about global warming: instead of worrying about the whole planet and all its oceans, how about asking a more personal question ... What about me? What about where I live? Or where my grandma lives? Or the North Pole? Or Siberia? What if I could take my curser, plop it onto any place on Earth and find out what's happened to temperatures right there. Click! And a graph instantly registers how much temperatures have changed in that very region...
Global warming: The new black
2013-01-19 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Economist: SOOT--also known as black carbon--heats up the atmosphere because it absorbs sunlight. Black things do. That is basic physics. But for years the institutions that focus on climate policy have played down the role of pollutants such as black carbon that stay in the atmosphere for a short time, and concentrated on carbon dioxide, which, once generated, tends to remain there. That may soon change. On January 15th, the fifth day that smog-darkened Beijings air-quality index was registering hazardous...

Global Warming and the Rare Haleakala Silverswords
2013-01-17 15:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: One of the most spectacular sights in the Hawaiian Islands is the Haleakala Volcano. This amazing volcano rises more than 10,000 feet from near sea level at its base. The ecosystems change dramatically as you drive up the twisting road that takes you to the summit. Near the top, you start to see the Silverswords. They are not numerous, but stand out sharply from the dark red rocky soil they grow on. In the early 20th century, the Silverswords suffered, but they have made a strong recovery from early...

Global Warming May Have Severe Consequences for Rare Haleakala Silversword Plants
2013-01-15 20:59:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: While the iconic Haleakala silversword plant made a strong recovery from early 20th-century threats, it has now entered a period of substantial climate-related decline. New research published this week warns that global warming may have severe consequences for the silversword in its native habitat. Known for its striking rosette, the silversword grows for 20-90 years before the single reproductive event at the end of its life, at which time it produces a large (up to six feet tall) inflorescence...
