An April 7, 2020 release was the latestinformation available on Internet concerning the IPCC AR6 status. It included the following excerpts:
The
Intergovernmental Panel on Climate Change (IPCC) has extended government and
expert review of the second order draft of the Working Group I contribution to
the Sixth Assessment Report (AR6) by six weeks to allow reviewers more time in
the light of disruption caused by the COVID-19 pandemic.
The
review, which opened on 2 March 2020 and was originally scheduled to end on 26
April, will now close on 5 June. Interested experts can register until midnight
CET on 29 May at https://apps.ipcc.ch/comments/ar6wg1/sod/register.php
The Working
Group I contribution to
the AR6, Climate Change 2021: The Physical Science Basis, will assess
large-scale climate changes, climate processes and feedback and regional
climate information. The Working Group I report includes an interactive online
atlas, which is also open for review comments.
The
draft report has been prepared by 233 authors from 65 countries.
The
first order draft of the Working Group I report received 23,462 comments from
750 expert reviewers. So far, 2,277 experts have registered to review the
second order draft.
However the only
“experts” with access to AR6 Working Group 1 (WG1) first or second order drafts
are those who “register” with IPCC.
Presumably the 750 who reviewed the first order draft and those who
finally “registered” to review second order draft continued concurring with
IPCC AR5 conclusions:
Human Influence on the climate system is clear. Increasing anthropogenic emissions have
thirty times the impact of increasing radiation from the Sun on global
temperatures.
One wonders how many
“experts” they chose were from the National Academy of Science (NAS). Wikipedia NAS description includes the
following:
Founded
in 1863 as a result of an Act of Congress that
was approved by Abraham Lincoln,
the NAS is charged with "providing independent, objective advice to the
nation on matters related to science and technology. … to provide scientific
advice to the government 'whenever called upon' by any government
department."
The NAS published the following paper online
on Nov 10, 2014. (More than a year
after the AR5 Climate Change September 2013 Physical Science Basis Working
Group Report)AR5 ClimateScience Bas
Shortwave and Longwave Radiative Contributions
to Global Warming Under Increasing CO2
The
paper’s Abstract began with:
In response to increasing concentrations of
atmospheric CO2, high-end general circulation models (GCMs) simulate an
accumulation of energy at the top of the atmosphere not through a reduction in
outgoing longwave radiation (OLR)—as one might expect from greenhouse gas
forcing—but through an enhancement of net absorbed solar radiation (ASR).
It
concluded with :
Altogether, these results suggest that,
although greenhouse gas forcing predominantly acts to reduce OLR, the resulting
global warming is likely caused by enhanced ASR.
The
bottom line is nearly 6 years ago NAS concluded global warming was driven, not
by increased blockage by anthropogenic CO2 (fossil fuel emissions), but by
increased absorbed radiation from the Sun.
It’s “unlikely”
the IPCC AR6 WG1 first or second order drafts reflect the NAS conclusion. It says a lot about the status of
climate debate that, nearly 6 years later, 233 authors, 750 “expert reviewers” of first draft, and
more than 2770 “expert reviewers” of second draft were either unaware of the
NAS conclusion or chose to ignore it.
My
campaign for governor is an attempt to expose their failure.
