Oceans Warming Up
Those who persist in denying, because the temperature outside their doors this morning was nippy, that global warming is real would do well to look at a new report by the United Nations Environmental Programme entitled, The UNEP Large Marine Ecosystem Report: a Perspective on Changing Conditions in LMEs of the World’s Regional Seas. The report shares measurements of ocean temperatures that demonstrate that in 61 out of the Earth’s 64 large marine ecosystems, water temperatures have increased significantly over the last quarter century.
Those increases in water temperature have been associated in large shifts in fisheries production, an increase in the number and extent of harmful algal blooms, and a surge in dead zones.
The UNEP does not yet have the report online, but it has been posted online by the US National Oceanic and Atmospheric Administration, which also provides a means for investigating climatic and ecological shifts in particular ecosystems reviewed in the report.
