The average temperature
in central England
rose at a slow rate
since 1700, which was
the coldest period
of the "Little Ice Age".
After freezing over regularly
during the "Little Ice Age",
the River Thames froze
for the LAST time in 1814,
as Earth moved into
the Modern Warming Period.
There's no scientific proof
that carbon dioxide (CO2)
is responsible for
ANY of the warming
since 1700.
The warming since 1700
was at least +2 degrees C. ,
about +1 degree C.
from 1700 to 1850,
and about +1 degree C.
from 1850 to 2018.
Human CO2 emissions
were NOT relevant
before 1850, so did not
cause the warming
from 1700 to 1850.
For 1850 to 2018,
half of the warming
was before 1940,
when little CO2 was
added to the atmosphere.
CO2 levels rose rapidly
after 1940 ... but there was
global cooling
from 1940 to 1975,
not global warming !
The UN's IPCC claims,
with no scientific proof,
that over half (over 50%)
of the warming since 1940
was caused by man made CO2.
Even if humans did cause
50% of the warming since 1940,
that adds up to only
a few tenths of a degree C. !
While it's impossible
for anyone to know
how much warming
CO2 causes, we can make
a worst case estimate.
We merely blame
100% of the warming
since 1940 on CO2 --
not just "over half",
as the IPCC claims.
That adds up to only
+1 degree of warming
per doubling of CO2 levels.
Based on recent growth
of CO2 levels in the air,
of 2% to 3% per year,
we can estimate
how long it would take
the average temperature
to increase +1 degree C..
The worst case estimate
for CO2 warming
of +1 degree C.,
would be 133 years,
with 3% annual CO2 growth,
and 200 years,
with 2% annual CO2 growth.
And that's assuming
people are still using
fossil fuels in 100
to 200 years!
The IPCC claim that CO2
is the 'climate controller'
is an unproven hypothesis.
The science is NOT settled.
The debate is NOT over.
Children are taught that CO2
is "pollution" that will destroy life.
That's nonsense !
NASA tells us “Carbon Dioxide
Controls Earth’s Temperature”.
That's also nonsense !
The UN's Intergovernmental
Panel on Climate Change
is composed of the
World Meteorological
Organization,
(weather forecasters),
and the United Nations
Environment Program,
(environmentalists).
The IPCC mandate
from the United Nations
was to focus ONLY on:
“a change of climate
which is attributed
directly or indirectly
to HUMAN activity... ".
4.5 billion years
of natural climate change
are ignored, as if
natural climate change
ceased to exist
in the middle of
the twentieth century !
Wait a minute !
That's exactly what
the global warmunists
want us to believe:
-- Natural climate change
ceased to exist
in the middle of
the twentieth century,
and humans became
the new "climate controller" !
The warmunits ignore the fact
that nothing unusual happened
to the average temperature
in the second half
of the twentieth century.
They never even try to explain
how natural climate change
could have become
a minor issue after 1940.
The global warmunist claims
are not based on real science,
just junk science !
