In a new paper,
two astrophysicists
suggest a “significant
percentage” of recent
climate change
has been solar-driven.
They attack the IPCC-preferred,
model-based, PMOD solar data set
and support the ACRIM, based on
observation, which shows increased
solar energy ( total solar irradiance,
or TSI ) from 1980 to 2000
( post World War II global warming
was from 1975 to 2003 ).
"The PMOD is based
on proxy modeled predictions,
“questionable” modifications,
and degraded, “misinterpreted”
and “erroneously corrected”
results."
"The PMOD TSI composite
“flawed” results were an
“unwarranted manipulation”
of data intended to support
man made global warming,
but are “contraindicated”."
"After the fact corrections
by those who did not participate
in the original science teams
of satellite experiments
are that erroneous interpretations
of the data can occur
because of a lack of detailed
knowledge of the experiment
and unwarranted manipulation
of the data can be made
based on a desire to support
a particular solar model
or some other non-empirical bias."
"We contend that
the PMOD TSI composite
construction is compromised
in both these ways.”
“The use of unverified modified
data has fundamentally flawed
the PMOD TSI satellite composite
construction.”
"The ACRIM TSI supports
the conclusion that
“a significant percentage”
of climate change
in recent decades
was driven by TSI variation."
“ACRIM composite trending
is well correlated with the
record of global mean temperature
anomaly over the entire range
of satellite observations
(1980–2018)
[Scafetta. 2009].
The climate warming hiatus
observed since 2000 is inconsistent
with CO2 greenhouse warming.
"A number of other studies
have pointed out that climate change
and TSI variability are strongly correlated
throughout the Holocene including
the recent decades
(Scafetta, 2009,
Scafetta and Willson, 2014,
Scafetta, 2013,
Kerr, 2001,
Bond et al., 2001,
Kirkby, 2007,
Shaviv, 2008,
Shapiro et al., 2011,
Soon and Legates, 2013,
Steinhilber et al., 2012,
Soon et al., 2014).”
“The global surface temperature
of the Earth increased
from 1970 to 2000
and remained nearly stable
from 2000 and 2018."
"This pattern is not reproduced
by CO2 AGW (man made) climate models
but correlates with a TSI evolution
with the trending characteristics
of the ACRIM TSI composite
as explained in Scafetta [6,12, 27]
and Willson [7].”
There is also a decent correlation
between the annual England
maximum and mean temperatures
and the annual sunshine hours:
