Unelected bureaucrats
who serve in, or support,
the United Nations,
want to limit the rise
of global land + ocean
surface temperatures
to no more +1.5 degree C.
from pre-industrial times.
We've already had
+1.0 degree C.
of global warming
since 1880, with an
honest margin of error
of +/- 1.0 degrees C.
( the data are very rough
estimates, with a majority
of the planet's surface
having no measurements,
so those "temperatures"
must be wild guessed,
by government bureaucrats,
to compile a global average
temperature! )
The local temperature
where you live
varies during the day,
and varies widely
during the year.
Why should anyone care
if their average temperature
had increased by
only +1 degree C.
over the past 138 years,
or might warm by another
+0.5 degrees C., at some time
in the distant future ?
They should not care !
Those temperature changes
are so small they would not
be noticed, if not for braying
leftists claiming a climate crisis
was in progress !
Global land + ocean
surface temperatures
are always presented
in anomaly form,
showing the changes
versus a base period
( often a 30-year average )
on a chart that has only a
1.0 or 1.5 degree C.
vertical range, making
tiny short-term
temperature variations
appear huge, when they'd
barely be visible
on an ordinary analog
glass ( red line ) thermometer.
The chart I chose for
the home page
of this Honest Global
Warming Chart Blog,
represents a
row of thermometers,
with each "thermometer"
showing the
average temperature,
for one year,
from 1880 through 2016.
That chart accurately
depicts surface global
warming since 1880,
but scares no one.
And no one should be scared.
But the chart
does infuriate leftists
who are members
of the "CO2 is Evil Cult",
which is almost all of them
-- they feel strongly
( leftists don't think )
that my global
warming chart
is not scary enough !
