IPCC’s Kangaroo Science…To Ignore Over 600 Papers Confirming Major Solar Impact On Climate

by P. Gosselin, July 17, 2018 in NoTricksZone


The upcoming 6th IPCC Sixth Assessment Report will be a “comprehensive assessment of the science” related to climate change and published in 2022. However, don’t expect it to be “comprehensive” at all as hundreds of scientific publications showing profound impacts by sun and oceans will go ignored.

Climate science has turned into a religion that centers on a single act of faith. Human CO2 is changing our climate.

In the past it was always understood that climate was impacted by a vast array of factors, such oceanic cycles, solar cycles, aerosols, cloud cover, etc. to name a few.

CHALLENGING THE SCIENCE BASIS OF THE PARIS CLIMATE AGREEMENT

by Antero Ollila, April 16 in WUWT


 

COP21 does not define the scientific basis of the agreement for the warming effects of the anthropogenic emissions, but it refers to a scenario. This scenario has not been defined in the COP21, but it can be found. The scientific resource of United Nations as well as of the COP21 is IPCC. The exact specification of IPCC is (Summary for Policymakers. In: Climate Change 2014. Mitigation of Climate Change”): “Baseline scenarios, those without additional mitigation, result in global mean surface temperature increases in 2100 from 3.7 °C to 4.8 °C compared to pre-industrial levels (range based on median climate response; the range is 2.5 °C to 7.8 °C when including climate uncertainty)”. Even though IPCC refers to multiple scenarios in the text above, the surface temperature increase to the average value of 4.25 ⁰C means one scenario only.

Finally, we have the IPCC Likelihood Scale:

Virtually certain – “All my cool scientist friends agree”.

Very likely – “We really hope this is true”.

Likely – “Two climate models out of three agree”.

About as likely as not – “Nobody has a clue”.

Unlikely – “This outcome offends us”.

Very unlikely – “We really don’t want you going down that path”.

Exceptionally unlikely – “Stephen McIntyre said it first so it can’t possibly be true.”

LES CONFLITS D’ INTERET AU GIEC

by Jo Moreau, 9 mars 2018, in Belgotopia


Complémentairement à l’article de Donna Laframboise, il semblerait que les différents groupes de travail du GIEC n’aient pas la même définition d’un conflit d’intérêt. On peut identifier deux formes principales de conflit d’intérêt : soit l’utilisation d’une étude rédigée par un auteur ou coauteur du GIEC, ce qui revient à publier des études qu’on utilisera ensuite dans une auto-justification, (voir aussi à ce sujet un billet précédent : http://belgotopia.blogs.lalibre.be/archive/2013/01/03/methodes-interpellantes-au-sein-du-giec.html ), soit la présence en ses rangs d’un salarié de l’industrie ou d’un membre ou d’un proche d’une ONG militant dans le domaine idéologico-politique.

On se rappelle que des contributeurs du GIEC, salariés de l’industrie chimique, avaient été accusés par diverses sources de conflit d’intérêt en 2016, que dire alors de membres ou proches d’ONG militantes, qui semblent de plus en plus se substituer aux organes démocratiques dans la direction de nos sociétés…

Crucial Climate Verdict, Naked Conflict-of-Interest

by D. Laframboise, January 29, 2018 in BigPicturesNews…


BIG PICTURE: In November 1995, the Intergovernmental Panel on Climate Change (IPCC) declared for the first time that humans were changing the climate. Its verdict turned on a single piece of then-unpublished research. Four months after the fact, the research was submitted to a prominent journal. Three months later it was published.

The world then learned that 25% of the IPCC personnel tasked with making its most crucial determination were involved with this research. In a naked a conflict-of-interest, these nine people, led by IPCC chapter head Ben Santer, had evaluated the persuasiveness of their own fledgling scientific work – and had judged it sound enough to change history.

Record 2018 snowfall continues increasing snowfall trends showing UN IPCC AR5 report is flawed

by Larry Hamlin, February 13, 2018 in WUWT


The record snowfalls of 2018 that are sweeping across the Northern Hemisphere and continuing the growth trend in winter snowfall levels provide yet more compelling evidence that the UN IPCC AR5 WG1 climate report and models are flawed because this report concludes that future snowfall level trends will only decline.(…)

Crucial Climate Verdict, Fledgling Evidence

by Donna Laframboise, January 26, 2018 in BigPictureNews


BIG PICTURE: In 1995, a 40-year-old climate modeller named Ben Santer was in charge of Chapter 8 of the UN’s upcoming Intergovernmental Panel on Climate Change (IPCC) report. Nothing in the other 49 chapters mattered more than the question his team was expected to answer: Was global climate change wholly natural – or was it partially caused by human activity?
