A CNN story complained
that Alaska was too hot
this summer.
So now a warmer climate
above the 49th parallel
is bad news !
CO2 emissions should have
a warming effect,
assuming lab experiments
reflect what actually happens
in the troposphere.
But there’s no evidence
global warming in the past
100 years has been harmful,
or even unusual for our planet.
One of the good things about
“global” warming is that
it isn’t really very global.
The warming has been
disproportionately in the
northern half of the
Northern Hemisphere,
where it is good news.
Scientist Svante
Arrhenius knew this
in 1906.
He wrote on page 63
of his book,
Worlds in the Making
(English, 1908)
(Världarnas utveckling
in Swedish - 1906):
“By the influence of the
increasing percentage
of carbonic acid [CO2]
in the atmosphere,
we may hope to enjoy
ages with more equable
and better climates,
especially as regards
the colder regions
of the earth,
ages when
the earth
will bring forth
much more
abundant crops
than at present,
for the benefit of
rapidly propagating
mankind.”
The CNN story claimed
unusually mild weather
in Alaska is something
to fear!
The CNN story
also mentioned ticks:
"Historically, that blood-sucking
bug would not survive the
Alaskan climate. Not anymore."
The truth:
The southern Alaskan climate
has NEVER been too harsh
for ticks and tick-borne
diseases.
Lyme disease is not
a tropical disease.
It was discovered
in relatively cold
Lyme, Connecticut.
Maine and northern Minnesota
are not too cold for deer ticks
that carry Lyme disease.
Winter nights in central Maine
are colder than in Anchorage,
Alaska.
Alaska’s record high temperature
was 100 degrees F. in 1915.
