Global Plant Productivity now on the Decline

Aug 25, 2010; 8:23 AM ET

According to a NASA funded study, earth has done an ecological about face. Global plant productivity that once flourished under warming temperatures and a lengthened growing season is now on the decline, struck by the stress of drought.

New research studying the latest satellite data shows that rising global temperatures has reached a tipping point where instead of being beneficial to plant growth, higher temperatures are causing drought, which has been causing a fairly recent decline in plant growth on a global scale, according to the University of Montana (UM).

An earlier UM study as recently from 2003 showed that land plant productivity was on the rise, according the Universe Today article.

The new study, which was expected to confirm the older one, instead, found that the impact of regional drought overwhelmed the positive influence of a longer growing season, driving down global plant production between 2000 and 2009, according to the Universe Today.

Here is a link to a related video of the story from NASA.
