But more importantly, according to Peter, scientists now have the tools to
test global circulation models and monitor worldwide changes in sea surface temperatures and circulation brought about by global warming.
When the paper's four authors first
tested the finished model's
global - warming predictions against those of the complex computer models and against observed real - world temperature change, their simple model was closer to the measured rate of
global warming than all the predictions of the complex «general -
circulation» models (see the picture which heads this post).
