The articles on the SAHFOS site (http://192.171.163.165/) bring up the same concerns, namely that anthropogenic climate change could affect
plankton and these changes
in the

in the
plankton communities have already started.
RE # 39 (sorry for being off - topic), there are still more threats to
plankton from GW, according to a NATURE article just out («Decline of the marine
ecosystem caused by a reduction
in the Atlantic overturning circulation,» Schmittner, Vol 434 No 7033, Mar 31, p. 628): If the Atlantic ocean conveyor is disrupted due to freshwater entering, then the nutrients for
plankton will not be churned up, perhaps reducing
plankton by half.

Other aspects of global warming's broad footprint on the world's
ecosystems include changes
in the abundance of more than 80 percent of the thousands of species included
