20 September 2001 Northern Hemisphere getting greener |
|
In the area above 40 degrees north latitude - which includes New York City, Madrid, Ankara and Beijing - satellite data show plants have been growing more vigorously since 1981 says a recent US agency report. One suspected cause is rising temperatures, possibly linked to the build-up of greenhouse gases in the atmosphere, according to a statement released by the National Aeronautics and Space Administration, the American Geophysical Union and Boston University. The report also found that Eurasia seemed to be greening more than North America, with more lush vegetation for longer periods of time, and that the growing season is now nearly 18 days longer in Eurasia than it was two decades ago, with spring arriving a week early and autumn delayed by 10 days. In North America, the growing season appears to be as much as 12 days longer. Contact: http://www.gsfc.nasa.gov/topstory/20010904greenhouse.html. |
