Amazon 2010-11 drought: detectable from space

In the image: red and orange identify areas where satellite measurements indicated reduced greenness of the Amazon forest during the 2010 drought. (Green patches are areas of enhanced greenness.) The maps differ only in the method used for determining vegetation greenness from optical data.

Guest blog: Extreme Amazon drought: fingerprints of climate change?
24/11/10 13:04
By Nick Sundt, WWF-US
The Amazon region is experiencing the third extreme drought in a dozen years -- and it may turn out to be the worst on record. The droughts coupled with recent research findings, suggest that rising atmospheric concentrations of greenhouse gases will rapidly increase the frequency and severity of droughts in the region. The implications for people, biodiversity and climate are ominous.

Water, North and South

Roughly 30 hours ago, I was rushing to the Stockholm airport. As I boarded the plane, I passed a small window used when guiding the walkway between the plane and the gate. A little sign a few feet in front of the nose of the plane stated the airport name, the city, and the latitude and longitude. Fifty-nine degrees north latitude, I thought. That’s the farthest north I’ve ever stood, at least on the ground. Then I laughed: this flight would carry me in 10 hours to Chicago, where I’d catch an 11-hour flight to Sao Paolo, Brazil, and then a last plane headed to the southwest for two hours to Cuiaba, Brazil, near the Bolivian border. From there, I drive straight south several hours to roughly 25 degrees south latitude, the southern-most point of my life. In basically a day and a half, I’d be spanning 85 degrees of latitude and pushing the extremities of my experience.But the contrasts were not merely of hemisphere and geography. My time in Stockholm was largely spent at a 2,500-person conference where water was only visible on PowerPoint slides and drinking fountains, while the Pantanal is a wetland the size of England and Scotland filled with jaguars, hyacinth macaws, and capybaras. The night sky is bright with stars and is one of the few places with essentially no planes visible in the sky. It has a great deal of water and very few people. Read More...
