Alarm about alarmism

by Judith Curry, July 15, 2017 in ClimateEtc.


In understanding climate change risk, and deciding on the ‘if’ and ‘what’ of ‘action’,  we need to acknowledge that we don’t know how the climate of the 21st century will play out (Deep Uncertainty, folks).  Four possibilities:

  1. It is possible that human-caused climate change will be swamped by much larger natural climate variability.

  2. It is possible/plausible  that the sensitivity of the climate is on the low end of the IPCC envelope (1.0-1.5C), with a slow creep of warming superimposed on much larger natural variability.

  3. It is possible/plausible that the IPCC projections are actually correct (right for the wrong reasons; too much wrong with the climate models for much credibility, IMO).

  4. It is possible that AGW and natural variability could conspire to cause catastrophic outcomes

MOST EUROPEANS AND 2/3 OF BRITONS REJECT IPCC ‘CLIMATE CONSENSUS’

from Global Warming Policy Forum, July 12, 2017


A new opinion poll of 10,000 European citizens reveals majority of Europeans reject the claim that climate change is mainly or entirely caused by humans.

For the last few decades, questions about the causes and impacts of climate change have dominated the climate debate. The IPCC and many climate scientists have been claiming relentlessly that the global warming trend since the second half of the 20th century is mainly if not entirely man-made, i.e. as a result of anthropogenic greenhouse gas emissions. This dogma is habitually claimed to be the global climate consensus.

A Growing Volume Of Evidence Undercuts ‘Consensus’ Science

by Kenneth Richard, July 3, 2017 in NoTricksZone


During the first 6 months of 2017, 285 scientific papers have already been published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media.

These 285 new papers support the position that there are significant limitations and uncertainties inherent in our understanding of climate and climate changes.  Climate science is not settled.

97% de scientifiques d’accord avec la théorie du dérèglement climatique ?

by Christian Gérondeau, 18 juin 2017, in Atlantico


Les hommes politiques, à l’image de Barack Obama avancent que 97% des scientifiques sont d’accord sur les causes humaines et les dangers du réchauffement climatique. Des chercheurs ont étudié l’ensemble des 11 944 publications sur le climat parues entre 1991 et 2011. Les résultats publiés en 2013 montrent que près de 66% des publications n’expriment pas d’avis, ni positif, ni négatif sur le réchauffement climatique.

The New ‘Consensus’ On Global Warming – a shocking admission by “Team Climate”

in Anthony Watts, June 20, 2017

By MICHAEL BASTASCH AND DR. RYAN MAUE


A scientific consensus has emerged among top mainstream climate scientists that “skeptics” or “lukewarmers” were not long ago derided for suggesting — there was a nearly two-decade long “hiatus” in global warming that climate models failed to accurately predict or replicate.A new paper, led by climate scientist Benjamin Santer, adds to the ever-expanding volume of “hiatus” literature embracing popular arguments advanced by skeptics, and even uses satellite temperature datasets to show reduced atmospheric warming.

More importantly, the paper discusses the failure of climate models to predict or replicate the “slowdown” in early 21st century global temperatures, which was another oft-derided skeptic observation.

It’s Said That ‘97% of Climate Scientists Agree’ About Global Warming – But Do They?

by Neil Frank, June 9, 2017


A variety of studies have purported to find an overwhelming consensus among climate scientists on global warming. However, the studies rarely specify what it is to which the scientists agree

Neil L. Frank, Ph.D. (Meteorology), was the longest-serving Director of the National Hurricane Center (1974–1987) and is retired Chief Meteorologist of KHOU-TV, Houston (1987–2008). Living in Fulshear, TX, he continues research on global climate change while serving as a Fellow of The Cornwall Alliance for the Stewardship of Creation.

End Game of Climate Wars: Clive James discusses how it plays out (slowly)

by JoNova, 2017


The best way to kill off the Climate Debate is to do what Team-Alarm has done for years — stop talking about whether it’s real, and just project forwards, detailing the collapse. For twenty years others have been saying “the debate is over”. Now the tables are turning. The debate really is over, skeptics won, and what’s left is to watch it continue to unravel. Clive James argues that it won’t collapse like a house of cards… (an extract from the new IPA book Climate Change: The Facts 2017.)

Politics Disguised as Science: When to Doubt a Scientific ‘Consensus’

by Jay Richards, April 19, 2017


Anyone who has studied the history of science knows that scientists are not immune to the non-rational dynamics of the herd.

This week’s March for Science is odd. Marches are usually held to defend something that’s in peril. Does anyone really think big science is in danger? The mere fact that the March was scheduled for Earth Day betrays what the event is really about: politics.
