Lots of carbon dioxide
has been added to the
atmosphere since 1940,
as world economies
began expanding again,
after the Great Depression
of the 1930s.
The global average
temperature is claimed
to be up +0.6 degrees C.
from 1940, through the
end of 2018.
I’d say an honest
margin of error
is at least
+/- 0.5 degrees C.,
because there were
so few Southern
Hemisphere
temperature
measurements
before 1950,
but never mind those
error margins for now.
The +0.6 degrees C.
global warming,
in the past 78 years,
is equivalent to
less than
+0.8 degrees C.
warming per century,
which is a harmless
rate of warming.
CO2 is actually
beneficial,
if you consider
the ‘greening’
of our planet
from more CO2
"plant fertilizer"
in the air.
I've just summarized PAST
global warming, since 1940
-- the cause is unknown --
but people hate unanswered
questions, so they invent
the "answers" they prefer.
The climate alarmists
blame humans, and many
scientists, but far from all,
blame humans for "over 50%"
of the warming after 1950.
Everything predicted about
FUTURE global warming,
however, is nothing more
than a wild guess,
unrelated to real science.
PAST CLIMATE REALITY:
There has been mild,
intermittent global warming
for the PAST 325 years
which was 100% good news.
FUTURE CLIMATE FANTASY:
In the fantasies of leftists,
all FUTURE global warming
will be 100% bad news,
completely unlike the
past global warming.
The "scientific proof"
of their predicted
100% bad news
FUTURE warming is:
"We're big shot government
scientists, and we say so ...
and we're going to keep making
the same scary climate predictions
for another 30 years ... because
that's what we get paid for.
Do what we say,
and don't ask
any questions.
Even if we are wrong,
we can't afford
to wait and see
-- do what we say
anyway! "
Do what we say,
and don't ask
any questions.
Even if we are wrong,
we can't afford
to wait and see
-- do what we say
anyway! "
