Actually, if gobal warming occurs, the North American continent will generally get
colder.
Experts say if global warming continues, the Gulf Stream will shut down. The heat it brings to the Gulf of Mexico will cease. No more balmy south & southeast USA, so no warm fronts holding back those Arctic Clippers that sweep down from Canada.
Actually, this has been completely discredited. This
BS, circulated by clowns, otherwise known as politicians
and journalists, was, however, well covered in the
media, peaking around 2004-2005.
Science magazine (not clowns) refuted this in R.A. Kerr's
2006 paper, "Global Climate Change -- False Alarm:
Atlantic Conveyor Belt Hasn't Slowed Down After All."
And New Scientist magazine (not clowns either, but
one of the original sources of the myths taken up by
the clowns) summed up the voluminous evidence
to the contrary in Nov 2006 in "No New Ice Age
for Western Europe."
However, the facts didn't make good headlines, so the
myth lives on.
It is quite frustrating to see so many smart people
with the wool pulled over their eyes by this nonsense.
