Why Cities? Ending Climate Change Begins in the City

The climate change debate has been going on for years, with people on both sides of the fence arguing for its existence — and against it. It’s hard to argue or turn a blind eye to the fact that, as the world’s population continues to grow, cities are becoming more and more crowded and the day-to-day pollution put into the environment by humans is starting to have an effect on our world. The C40 Cities Climate Leadership Group (C40) is a network of the world’s mega cities committed to addressing climate change, and have a meaningful global impact. They have created this stellar interactive graphic to help spread the news.

More wildfires likely in Patagonia

A major climate oscillation in the Southern Hemisphere is expected to intensify in the coming decades, likely increasing wildfire activity in the southern half of South America. This 2010 photo shows the aftermath of a wildfire outside the town of Futaleufu in southern Chile.

Tundra fires may speed climate change

After a 10,000-year absence, wildfires have returned to the Arctic tundra, and new findings raise concerns the fires could accelerate the release of carbon into the atmosphere. Scientists quantified the amount of soil-bound carbon released into the atmosphere in the 2007 Anaktuvuk River fire, which covered more than 400 square miles on the North Slope of Alaska’s Brooks Range.

Pollen fossils from Antarctic’s warmer days

By studying fossilized grains of pollen, researchers have reconstructed the climate history of the Antarctic Peninsula, which gave up its vegetation about 12 million years ago. Scientists are studying the region because it has warmed significantly in recent decades.

Cloudscapes: A Walk Into the Clouds

As children, we often dream of flying up and touching the clouds; looking skyward, they seem almost within reach. Now, through a collaboration between Japanese architect Tetsuo Kondo and German climate engineering firm Transsolar, that dream has become reality. By using three different levels of air with different temperatures and humidities the team has successfully created a cloud that hangs like magic on the roof of the space. Visitors to the 800 square meter room at the Architecture Biennale Arsenale exhibition travel up, through and above the clouds on spiraling ramps. It’s as if they’ve been given wings.
