IPCC and UNFCCC
The Intergovernmental Panel on Climate Change (IPCC) [1] is an intergovernmental body of the
United Nations, dedicated to provide the world with an objective, scientific view of climate
change, its natural, political and economic impacts and risks, and possible response options.
It was established in 1988 by the World Meteorological Organization (WMO) and the United
Nations Environment Programme (UNEP), and later endorsed by the United Nations General
Assembly. Membership is open to all members of the WMO and UN. The IPCC produces re-
ports that contribute to the work of the United Nations Framework Convention on Climate
Change (UNFCCC), the main international treaty on climate change.
The objective of the UNFCCC is to "stabilize greenhouse gas concentrations in the atmosphere at a
level that would prevent dangerous anthropogenic (human-induced) interference with the climate
system".
But this objective emanates from the assumption that almost only Green-House Gases (GHG)
are responsible for an observed temperature increase since the end of the ‘Little Ice Age’ at
1850, and that for an inclining concentration of these gases mostly fossil fuel emissions are
liable.
Therefore, the UNFCCC and as its acting body the IPCC is primarily focusing on human emis-
sions and tries to explain all global warming exclusively by human activities, while any natural
variations are almost completely excluded.
As a consequence, also most of the state-sponsored climate research was concentrating only
on the human influence and largely neglecting natural variations.
The IPCC does not accomplish original research, nor does it monitor climate or related pheno-
mena itself. Rather, thousands of ‘experts’ from political and environmental organizations con-
tribute on a voluntary basis to writing and reviewing reports, which are mostly captured by the
governments without any larger modifications.
From selectively screening the climate literature the IPCC and related institutions conclude that
climate science is settled and that 97% of climate scientists or even more would make humans
responsible for a climate change.
The So-Called AGW-Consensus
The statement of settled science and a scientific consensus on Anthropogenic Global Warming
(AGW) goes back to evaluations like that of Cook et al. [2], who examined 11,944 climate
abstracts from 1991–2011 in the peer-reviewed literature matching the topics ‘global climate
change’ or ‘global warming’. They found that 66.4% of abstracts expressed no position on AGW,
32.6% endorsed AGW, 0.7% rejected AGW and 0.3% were uncertain about the cause of global
warming (see left graphic).
In their further analysis then the authors only consider those abstracts, which explicitly or im-
plicitly expressed a position on AGW (32.6% endorsed + 0.7% rejected + 0.3% uncertain -->
total 33.6%), and from this they conclude that 97.1% (32.6/33.6 %) endorsed the consensus
position that humans are causing global warming (right graphic).
Independent of the fact that in science a hypothesis is not confirmed or rejected by voting or
by a consensus, in such calculation the largest group of climate scientists (66.4%), which did
not explicitly express a position on AGW, is completely embezzled.
It is adventurous how Cook et al. - and with them the IPCC - infer from such manipulated data
a 97% AGW-consensus of climate scientists. The authors generalize selectively deduced data
from abstracts partially written more than 20 years ago, and mostly published to present a
scientific result and not to express a position on AGW. Indeed, some of these scientist may
also have supported the AGW-hypothesis, but others not.
A detailed scrutiny of Cook‘s data even shows the exact opposite of a consensus. M. Fiedler [3]
looked more carefully to the original data and found that from the 11,944 abstracts just 64
explicitly endorsed and quantified AGW as the dominant reason for the climate change (50+%).
This is not more than 0.54% of all abstracts. 922 abstracts (7.72%) explicitly endorsed, but did
not quantify or minimize it, and 2,910 (24.36%) only implicitly endorsed AGW. All the others
had no position or were rejecting AGW. The only thing we can definitely learn from such
investigation is that 32% of all abstracts concede (explicitly or implicitly) some smaller fraction
of anthropogenic global warming, and only 0.54% hold humans mainly or alone responsible
for global warming. So, it is a willful deception of the public and the politicians to deduce from
such kind of investigations any scientific consensus.
An even worse evaluation is presented by Powell [4], who assumes that the extent of a
consensus can be determined by the number of scientists, who contradict the AGW-hypo-
thesis. With this method he finds 5 surveys in 54,195 articles and derives from this an average
consensus of 99.99%.
Applying this method, right away we will find a 100% consensus for the hypothesis that
witches are responsible for global warming, and burning of witches is an appropriate means to
protect humans against disasters and climate catastrophes. This will be the result of screening
the peer-reviewed literature, since nowadays no serious article can be found, where burning of
witches as adequate measure against potential threads is gravely discussed or mentioned, and
therefore also no expert can be found who contradicts such scenario, which nowhere is
considered and which goes back to the middle age.
This kind of investigations is absolutely nonsense, and it is highly disqualifying that such logics
has meanwhile been taken over by the German Government to proclaim a 99% AGW-con-
sensus of climate scientists (Bundestags-Drucksache 19/12631 [5])!
IPCC‘s New Perception
All this is no longer real science and objective consultancy of politicians. Rather the IPCC itself
converted to a political organization, which disseminates climate religion and has turned aside
from serious climate science. Their thousand pages long Assessment Reports, in particular the
chapter Summary for Policy Makers (SPM) demonstrates, how the IPCC modified its original
mission from consulting governments to an active political organization. The reports are dri-
ven by an extreme form of fear based activism and speculation instead of presenting settled
climate facts. They are no longer scientific reports but converted to political statements with
the essence to convince politicians and media that any observed climate change is only man-
made and natural effects have no influence on the climate.
We know, declarations of a forthcoming climate catastrophe are most attentively recognized
by the public and politicians. To some extent this even goes along with end time hysterics, as
this could be observed with prognoses for a population explosion and the feared starvation
crisis or the forest destruction in the 80s. But serious institutions and reliable climate scientists
do not further invigorate such tendencies or dramatize speculations that create a religious war
in our society and a polarization between industrialized and developing countries with claims
for guilt and expiation (see e.g. requests for a deed of partnership: The Great Transformation
[6]). Serious science concentrates on factual research which can confirm or dismiss a theo-
retical prediction.
Therefore, it is high time for a fundamental amendment of the climate organizations.
This demand is strongly supported by many climate scientists and experts, see e.g.:
•
Letter to the US President and Petition to withdraw from United Nations Framework Convention
on Climate Change (UNFCCC), signed by 310 international scientists, Lindzen et al.,
February 23, 2017 [7].
•
REAL climate science shows Trump was right to Exit Paris, Declaration of scientists as re-
sponse to a letter of MIT President Reif to the MIT community, in which Reif criticizes Presi-
dent Trump’s decision to exit the Paris climate agreement, Marko et al., 2017 [8].
•
There is No Climate Emergency, World Climat Declaration of Independent Scientists, signed
by more than 1870 scientists of 61 countries, sent to the UN and UNFCCC,
G. Berkhout et al., September 2019 [9].
There is hardly any other discipline in which so many articles appear, both by climate experts
and scientists from other disciplines, which critically question the data and publications pub-
lished by official institutions or the governments and point to obvious contradictions and
misinterpretations. They deliver an important contribution to the active climate debate. With-
out claiming completeness, here we list some of these alternative associations as control
bodies of the IPCC and advocates of serious science.
Non-Governmental International Panel on Climate Change
Already quite early, the one-sided considerations of a purely man-made climate change were
recognized by some scientists. Therefore, almost at the same time as the IPCC, the Non-
Governmental International Panel on Climate Change (NIPCC) was founded by Prof. Fred
Singer to form an alternative scientific voice to the IPCC.
For more than 70 years, Prof. Singer had outstanding positions in the sciences. He was direc-
tor of the Center for Atmosphere- and Spacephysic at the University of Maryland (1953-62),
first director of the National Weather Satellite Service (1962-64), founding dean of the School
of Environmental and Planetary Sciences at the University of Miami (1964-67), served in
various departments and was a Professor of Environmental Sciences at the University of
Virginia. His specialty was atmospheric and space physics.
Sadly, Fred Singer passed away in April 2020 at the age of 95. But until old age, he still used all
his strength to ensure that science did not degenerate to a water carrier of politics with a
rapidly increasing dependency of environmental sciences from politics.
Therefore, he had already founded the Science and Environmental Policy Project (SEPP) in
1990, which - like the NIPCC - in many scientific reports positioned itself clearly against an
increasing ideologization of environmental sciences and tried to counteract the emerging
scaremongering of man-made climate change.
With the death of Fred Singer, the NIPCC has not published new alternative assessment re-
ports. However, other associations and scientists, who have critically questioned the work of
the IPCC parallel or in cooperation with the NIPCC and SEPP continue to do this very actively.
European Institute for Climate and Energy
In Germany, for example, the European Institute for Climate and Energy (EIKE) has extensive
internet activity, where critical reports from all over the world on climate change and energy
supply appear daily, together with plenty of comments from a broad readership.
Daily Newsletter on Climate and Energy
The climate news from Prof. Vahrenholt and Prof. Lüning in form of a daily newsletter on
climate and energy topics together with the blog "Kalte Sonne" and the “Climate Show“ on
YouTube inform regularly about reports on new scientific results from the climate sciences.
The reports are mainly focussing on new publications about the influence of natural control
factors on climate events. Reviews and critical comments on other articles and press releases
also appear there. The aim of the website is also to provide a thematically sorted overview of
the continuously growing number of blog articles.
Climate Intellicence Foundation
The Climate Intelligence Foundation (CLINTEL) is an independent foundation that operates in
the fields of climate change and climate policy. CLINTEL was founded in 2019 by emeritus
professor of geophysics Guus Berkhout and science journalist Marcel Crok. In 2019 CLINTEL
published a World Climate Declaration with the title: There is no Climate Emergency. This
declaration was addressed to politicians and the UN. Meanwhile it is signed by more than
1,870 scientists from 61 countries.
In May 2023 CLINTEL published the book: The Frozen Climate Views of the IPCC - An Analysis of
AR6. A team of eight scientists, in addition to several anonymous expert reviewers, from the
Clintel network, have analyzed several claims from the Working Group 1 (The Physical Science
Basis) and Working Group 2 (Impacts, Adaptation and Vulnerability) reports.
Climate Realists
In Norway, a group was formed years ago, which is mainly active in Northern Europe and calls
itself Climate Realists.
Since 2021 it publishes its own scientific journal, Science of Climate Change. This journal has a
high scientific level with reviewers from proponents and critics of human climate change and
also with contributions from both sides. In contrast to many journals controlled by the IPCC, in
Science of Climate Change as Open Access Journal also climate-critical articles can be publish-
ed. As a long-standing member, the Nobel Prize Laureate Prof. Ivar Giaever also supports the
activities of the Climate Realists.
CO
2
Coalition
Finally, we refer to the CO
2
Coalition, which was initiated by Prof. Will Happer from Princeton
University and Prof. Richard Lindzen from MIT. In particular, this association points to the
advantages of a higher CO
2
concentration in the atmosphere. Plants absorb CO
2
from the air
through photosynthesis. Without this process, plants would not be able to grow, and without
this process, there would be no life on Earth. The growth of C3 plants in particular is signifi-
cantly promoted by a higher CO
2
content in the atmosphere and thus also contributes to a
more secure nourishment of the world's population.
In May 2023, Prof. John Clauser, Nobel Prize Laureate in Physics 2022 (awarded for his quan-
tum physics work) was elected as an additional director to the board of the CO
2
Coalition.
We close here with his words:
"The popular narrative about climate change reflects a dangerous corruption of science that
threatens the world’s economy and the well-being of billions of people. Misguided climate science
has metastasized into massive shock-journalistic pseudoscience.
In turn, the pseudoscience has become a scapegoat for a wide variety of other unrelated ills. It has
been promoted and extended by similarly misguided business marketing agents, politicians,
journalists, government agencies, and environmentalists. In my opinion, there is no real climate
crisis. There is, however, a very real problem with providing a decent standard of living to the world’s
large population, and an associated energy crisis. The latter is being unnecessarily exacerbated by
what, in my opinion, is incorrect climate science."
Here only a small collection of announcements from official and non-official ‘climate experts‘
about our climate, which finally led to the founding of the IPCC; and also some statements of
representatives or members of this association, which may reflect the seriousness of these
forecasts, but also the style, how pure climate speculations are presented as facts:
•
As early as 1986, climate researchers warned of droughts, famines, storms, floods, poles
will soon be ice-free, the glaciers of the Alps and the Himalayas will have disappeared by
2040, and as illustrated, for example, on the front page of the journal “Der Spiegel” in 1986,
Hamburg, New York or Hong Kong will no longer exist in 20 years, i.e. in 2006.
•
Also James Hansen, previous head of NASA‘s Goddard Institute, saw New York disappear in
the floods. He announced at a hearing of the American Congress in 1988:
“In 20 years will the West Side Highway (along the Hudson River) be under water, and the win-
dows along the road will be fixed with adhesive tape because of the strong winds."
When I passed the highway in 2010, the water level was almost the same as it was 20 years
earlier, maybe a few cm higher in agreement with the official tide gauge measurements,
showing a linear incline over the last 150 years of not more than 1.3 to 1.8 mm per year.
After all, an actual study just found that New York could be more affected by flooding than
other coastal cities, because of a sinking subsurface at an average of one to two milli-
meters per year. While the skyscrapers based on rock, hardly sink, coastal areas with softer
subsoil are much more affected (Parsons et al. [10]).
A particular example of surface sinking is Indonesia's capital, Jakarta. Large parts of the city
sink by about 6 cm per year, 30 times the rise of sealevels. This is mainly attributed to the
extraction of drinking water, which in turn contributes to the sinking of the country.
•
In 1989, Noel Brown, at that time the UN's chief secretary for the environment, announced:
"In 11 years, entire nations could disappear from the face of the Earth as a result of rising sea
levels, if global warming is not stopped by the year 2000“.
Fortunately, the Maldives and Fiji Islands still exist. They are not nearly as endangered as
always portrayed, not least because coral reefs are growing faster (8 – 30 mm/year) than
sea levels are rising.
It is also known that there are regions where the sea level has lowered relative to the coast
instead of rising. Examples are Helsinki or the Norwegian coast, where after the melting of
glaciers the land continues to rise for thousands of years.
•
In 2006, Al Gore, former U.S. Vice President, stated in the opening credits to his film An
Inconvenient Truth, for which he was awarded by the Nobel Peace Prize: "If drastic measures
are not taken to reduce greenhouse gases within the next ten years, the world will reach a point
of no return. The situation is a real planetary emergency."
Incidentally, this film tries to demonstrate the greenhouse effect in a model experiment,
which, however, has nothing to do with this effect and can be seen as a clumsy, even dan-
gerous deception. The goal of such a fake demonstration is clear, to simulate the effect of
CO
2
emissions by men and to derive the imperilment of the planet by these emissions,
which in turn calls activists like Fridays for Future or the Last Generation onto the scene.
With the point of no return Mr. Gore certainly meant that the polar bear population is in-
creasing significantly again, since fewer are released for shooting. And the Arctic ice has
unfortunately been increasing again for several years, so that the Northern Passage will no
longer be possible.
•
In 2007, Rajendra Pachauri, President of the IPCC until 2015, declared: "If no fundamental
measures are taken within the next five years, it will be too late". And: "What we do over the next
three years will determine our future. That's the definite time."
•
King Charles III, in 2009 still Prince Charles, announced: "Without financial incentives or de-
terrence we have only 8 years to prevent an irretrievable collapse of our climate and ecosystem
and everything that comes with it".
•
Of course, also German prophets should not be missing in such doomsday scenarios. As
early as 2000, Mojib Latif, now head of the GEOMAR Helmhotz Institute in Kiel, predicted
that our children would no longer know what snow is: "Winters with severe frost and a lot of
snow like twenty years ago will no longer exist in our latitudes".
And in his new book from 2020 he says: "What is currently happening on our planet is unpre-
cedented worldwide. Primarily due to the CO
2
emissions produced by combustion of fossil fuels,
the temperature on Earth is rising at an unprecedented speed with already visible and in some
cases drastic consequences."
What Latif cites, are not observations, but the results of computer models that calculate
significantly higher temperatures than they are measured.
•
And Stefan Rahmstorf from the Potsdam Institut für Klimafolgenforschung was already in
2006 and now again talking about new domino effects that can be triggered by climate
change, such as the overturning of the Gulf Stream and the destabilization of the West
Antarctic ice sheet.
As paleoclimatologist he knows that temperatures over the last 570 million years have
been predominantly much warmer, in some cases more than 10°C compared to our
current temperatures. In these so-called Warm Ages the pole caps were ice-free.
We are actually living in an Ice Age, the Quaternary, and within this Ice Age in an Interglacial,
the Holocene, as a slightly warmer period. But it is not known that the Warm Ages or the
Interglacials would have led to tipping points or the destruction of fauna and flora. On the
contrary, together with a significantly higher CO
2
concentration this has led to better living
conditions for humans and plants.
•
Unfortunately, with the Interim Report published in 2018 and the Sixth Assessment Report
of the IPCC in 2021, nothing has changed in the forecasts. "Warming of 1.5°C or more increa-
ses the risk of irreversible changes such as the loss of some ecosystems, and man-made
emissions of CO
2
must fall by 45% within the next 12 years and reach 'zero' in 32 years."
