Is climate change REALLY the culprit causing California’s wildfires?

by L. Kummer, December 14, 2017 in A. Watts, WUWT

We’re told that climate change caused or intensified California’s wildfires — and that such fires are getting worse. As usual for such scary stories, these claims are only weakly supported by science — except for the ones that are outright fabrications. See what scientists say and decide for yourself.

Dueling science: One study says melting Antarctic ice sheet will flood US east coast, others say ‘uncertain’

by Anthony Watts, December 13, 2017 in WUWT

(…) All of these press releases appeared within a couple of hours of each other on EurekAlert, which is a Science PR clearing house. They will all inevitably get turned into stories by the media. Who could blame the public for being confused when we have such certainty/uncertainty battles like this going on in climate science?

It seems Yogi Berra was right.

It’s tough to make predictions, especially about the future.

Study: a ‘statistically significant downward trend since 1950 exists’ in hurricane landfalls

by Anthony Watts, December 9, 2017 in WUWT

This is going to rattle some cages, while at the same time vindicating Dr. Roger Pielke Jr. A new study in Geophysical research Letters studies hurricane activity in the Atlantic concludes that a “statistically significant downward trend since 1950 exists”.

Retraction request for Harvey et al. attack paper on Dr. Susan Crockford

by Dr. S. Crockford, in A. Watts, December 5, 2017 in WUWT

Essay by Dr. Susan Crockford (republished from her website )on Retraction request to Bioscience: FOIA emails document another harsh criticism of Amstrup’s 2007 polar bear model

Today I sent a letter to the editors of the journal Bioscience requesting retraction of the shoddy and malicious paper by Harvey et al. (Internet blogs, polar bears, and climate-change denial by proxy) published online last week.

The letter reveals information about the workings of the polar bear expert inner circle not known before now, so grab your popcorn.

“Pseudoscience is embraced, it might be argued, in exact proportion as real science is misunderstood”… Except in the case of climate change.

by David Middleton, December 5, 2017

(…) Petroleum geologists tend to be sedimentary geologists and sedimentary geology is essentially a combination of paleogeography and paleoclimatology. Depositional environments are defined by physical geography and climate. We literally do practice in a different world, the past. Geologists intuitively see Earth processes as cyclical and also tend to look at things from the perspective of “deep time.” For those of us working the Gulf of Mexico, we “go to work” in a world defined by glacioeustatic and halokinetic  processes and, quite frankly, most of us don’t see anything anomalous in recent climate changes.

Do 40,000 volcanoes matter?

by JoNova, December 5, 2017

The scope of our ignorance on the sea floor is really something. There are 1,500 active volcanoes on land, but on the sea floor we are still discovering them all the time. at least 39,000 of them rise one kilometer off the sea floor, but there are suspicions there might be up to 3 million, holey moley. The Hilliers paper estimates that 24,000 submarine volcanoes were not yet discovered in 2007.  Wikimedia is trying to list them. Good luck.

November Arctic Refreezing 2017

by Ron Clutz, December 2, 2017 in ScienceMatters

Earlier observations showed that Arctic ice extents were low in the 1940s, grew thereafter up to a peak in 1977, before declining.  That decline was gentle until 1994 which started a decade of multi-year ice loss through the Fram Strait.  There was also a major earthquake under the north pole in that period.  In any case, the effects and the decline ceased in 2007, 30 years after the previous peak.  Now we have a plateau in ice extents, which could be the precursor of a growing phase of the quasi-60 year Arctic ice oscillation.

Global Temperature Report: November 2017

by UAH and Dr. J. Christy in A. Watts, December 4, 2014 in WUWT

The average global temperature drop between October and November, 2017, tied for the fifth largest one-month-to-the-next drop in the 39-year satellite temperature record, according to Dr. John Christy, director of the Earth System Science Center (ESSC) at The University of Alabama in Huntsville. Compared to seasonal norms, the average temperature around the globe fell 0.27 C (almost 0.49 degrees F) between October and November. (The largest drop was from January to February 2013, when the global average temperature fell 0.32 C.)

A Veneer of Certainty Stoking Climate Alarm

by Rupert Darwall, November 28, 2017 in CompetitiveEnterpriseInstitut

This essay by Rupert Darwall explores the expressions of public certainty by climate scientists versus the private expressions of uncertainty, in context of a small Workshop on Climate organized by t he American Physical Society (APS). I was privileged to participate in this workshop, which included three climate scientists who support the climate change consensus and three climate scientists who do not — all of whom were questioned by a panel of disting uished physicists (…).

La modélisation du climat, science ou scientisme ?

by Uzbek, 21 novembre 2017, in Climato-Réalistes

Les prévisions climatiques à très long terme (2100) sont établies à l’aide de modèles qui ne sont rien d’autre des logiciels très complexes, dont le but est de reproduire le comportement du climat terrestre.

Comme on ne peut pas décrire ce qui se passe en tous les points de la terre, celle-ci est découpée en mailles de quelques centaines de kilomètres de côté. Les modèles utilisés par le GIEC pour son cinquième rapport d’évaluation (2013) avaient des résolutions relativement grossières (supérieures à 100 km). La situation évolue toutefois rapidement et les modèles climatiques les plus récents auraient une résolution plus fine (de l’ordre de 20 km).
