Study Shows More Shrubbery in a Warming World

December 16th, 2011 | Environmental

Scientists have used satellite data from NASA-built Landsat missions to confirm that more than 20 years of warming temperatures in northern Quebec, Canada, have resulted in an increase in the amount and extent of shrubs and grasses.

“For the first time, we’ve been able to map this change in detail, and it’s because of the spatial resolution and length-of-record that you can get with Landsat,” says Jeff Masek, the program’s project scientist. He’s based at NASA’s Goddard Space . . . → continue reading..: Study Shows More Shrubbery in a Warming World

2011: 10th Warmest Year, Warmest Year with La Nina Event, Lowest Arctic Sea Ice Volume

December 4th, 2011 | climate change

Geneva / Durban - Global temperatures in 2011 are currently the tenth highest on record and are higher than any previous year with a La Niña event, which has a relative cooling influence. The 13 warmest years have all occurred in the 15 years since 1997. The extent of Arctic sea ice in 2011 was the second lowest on record, and its volume was the lowest. These are some of the highlights of the provisional annual World Meteorological Organization . . . → continue reading..: 2011: 10th Warmest Year, Warmest Year with La Nina Event, Lowest Arctic Sea Ice Volume
