| From Monsters and Critics.com Nature News WASHINGTON, DC, United States (UPI) -- NASA scientists say global warming is reducing the oceans` primary food supply, posing a threat to fisheries and ecosystems. The National Aeronautics and Space Administration researchers reached that conclusion by comparing nearly a decade of global ocean satellite data with several records of Earth`s changing climate. They found whenever climate temperatures increased, marine plant life in the form of microscopic phytoplankton declined. When climate temperatures lowered, marine plant life became more vigorous or productive. 'The evidence is pretty clear that the Earth`s climate is changing dramatically, and in this NASA research we see a specific consequence of that change,' said oceanographer and study co-author Gene Carl Feldman of NASA`s Goddard Space Flight Center in Greenbelt. Md. 'It is only by understanding how climate and life on Earth are linked that we can realistically hope to predict how the Earth will be able to support life in the future.' The study is published in the current edition of the journal Nature. Copyright 2006 by United Press International © Copyright 2006,2007 by monstersandcritics.com.
