A 500-Year Record of Sea Level from Goa, India

by N.-A. Mörner, June 2017, in J. Coastal Research

Fortunately, as revealed in a number of recent studies, proof of such an acceleration of sea level rise remains elusive (see the many reviews we have posted on this topic under the subheading of Sea Level here). The latest work to demonstrate that there is nothing unusual, unnatural or unprecedented about current rates of sea level rise comes from a paper written by sea level expert Nils-Axel Mörner (Mörner, 2017) and published in the Journal of Coastal Research.

Evidence of variability of atmospheric CO2 concentration during the 20th century

by Ernst-Georg Beck, Discussion paper, May 2008

Since the 19th century, use of chemical methods has provided reliable atmospheric CO2 gas analyses results that have been obtained predominantly from the northern hemisphere. These direct chemical analyses results provide information on past atmospheric CO2 concentrations in addition to the modern direct atmospheric CO2 measurements since 1958 and the indirect reconstructions of past atmospheric CO2 from ice cores. Comprehensive literature indicates that the chemical methods have provided a systematic accuracy within ± 3 Vol% since 1857.

AGU: Extraordinary storms caused massive Antarctic sea ice loss in 2016

by Lauren Lipuma, June 23, 2017, in WUWT

In a new study, scientists puzzled by the sudden ice loss matched satellite images of Antarctica with weather data from the second half of 2016 to figure out what caused so much of the ice to melt. They found that a series of remarkable storms during September, October and November brought warm air and strong winds from the north that melted 75,000 square kilometers (30,000 square miles) of ice per day. That’s like losing a South Carolina-sized chunk of ice every 24 hours.

Conférence de Richard Lindzen à l’ESCPI

in Climato-Réalistes, 24 mai 2017

Richard Lindzen a donné mardi 23 mai 2017 à l’ESCPI (École supérieure de physique et de chimie industrielles de la ville de Paris) une conférence intitulée « Les origines et les bases de l’alarmisme climatique » .

Au cours de cette conférence le Professeur Richard Lindzen montre que les affirmations sur le changement climatique sont très exagérées et inutilement alarmistes.

Cette conférence est la réplique de celle qui avait été donnée aux Etats-Unis le 25 avril 2017 sous l’intitulé : « Thoughts on the Public Discourse over Climate Change ».

Elévation du niveau de la mer : la précision millimétrique des observations satellitaires est-elle crédible ?

by ‘Uskek’ , 16 juin 2017, in Climato-Réalistes

Les mesures satellitaires  prétendent mesurer l’élévation du niveau de la mer avec une précision millimétrique. Or La précision des radars altimétriques s’exprime en centimètres. Comment  dans ces conditions parvient-on à mesurer un taux d’élévation du niveau de la mer de 3,4 mm par an sur la période 1993-2015 ?

Les modèles du réchauffement global sont faux, la « pause » est réelle, reconnaît Ben Santer, alarmiste du climat

by Reinformation.TV, 21 juin 2017

Un papier scientifique publié cette semaine par Nature Geoscience du groupe « Nature », peu suspect de complaisance à l’égard des climatoceptiques, constate que le réchauffement climatique a été surestimé par les modèles de prédiction qui justifient l’action concertée contre les émissions de gaz à effet de serre. L’article a la particularité d’avoir pour auteur principal Ben Santer, l’un des pionniers du mouvement qui accuse l’activité humaine du réchauffement climatique.

Norway offers oil firms record number of Arctic blocks

by AFP/UKnews, June 21, 2017

Norway on Wednesday proposed to open up a record number of blocks in the Barents Sea to oil exploration despite protests from environmentalists and others fearing possible damage to the Arctic region.

The Norwegian oil and energy ministry offered oil companies 93 blocks in the Barents Sea and nine others in the Norwegian Sea, all located beyond the Arctic Circle.

A REVIEW OF ‘SKEPTICAL SCIENCE’ ALLEGED MYTHS

by Ken Gregory in Friends of Science, June 22, 2017

Pdf version available here

A website called ‘Skeptical Science.com’ is popular among climate alarmists. The website alleges to refute claims by climate skeptics that global warming is not a crisis. The website features a list of 10 “Most Used Climate Myths” by climate skeptics at the top left part of the webpage.  I review and rebut each rebuttal of the 10 alleged myths.

Why “Climate Science” Snubs Climatic Temperature

by Leo Goldstein, June19, 2017 in WUWT

When something pretending to be a science cannot adequately define a quantity for its central subject, this something is inarguably a pseudo-science. This is certainly the case in the self-professed “climate science.” It proposes the hypothesis of a dangerously warming climate, but does it define a meaningful climatic temperature that can be robustly calculated from the observations at the current time? To the extent that it does define climatic temperature (meaningfully or not), does it pay much attention to this quantity? The answer to both these questions is a resounding NO.

The Laws of Averages: Part 2, A Beam of Darkness

by Kip Hansen, June 19, 2017 in WUWT

As both the word and the concept “average” are subject to a great deal of confusion and misunderstanding in the general public and both word and concept have seen an overwhelming amount of “loose usage” even in scientific circles, not excluding peer-reviewed journal articles and scientific press releases,  I gave a refresher on Averages in Part 1 of this series.  If your maths or science background is near the great American average, I suggest you take a quick look at the primer in Part 1 before reading here.

Plastic pollution in the Antarctic worse than expected

by British Antarctic Survey, June 19, 2017 in ClimateChangeDispatch

The levels of microplastic particles accumulating in the Antarctic are much worse than expected, a team of experts has warned.

The continent is considered to be a pristine wilderness compared to other regions and was thought to be relatively free from plastic pollution. However new findings by scientists from University of Hull and British Antarctic Survey (BAS) have revealed that recorded levels of microplastics are five times higher than you would expect to find from local sources such as research stations and ships

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.

Study: California once had 150 straight years of stormy, wet, weather

by Vanderbilt University, from WUWT, June 20, 2017

Wet and stormy weather lashed California coast… 8,200 years ago

First high resolution evidence of California climate response to Holocene 8.2 ka event

The weather report for California 8,200 years ago was exceptionally wet and stormy.

That is the conclusion of a paleoclimate study that analyzed stalagmite records from White Moon Cave in the Santa Cruz Mountains published online Jun. 20 in Scientific Reports.

The Golden State’s 150-year stretch of unusually wet weather appears to have been marked by particularly intense winter storms and coincides with a climate anomaly in Greenland ice cores first detected in 1997. Before this “8.2 ka event” was discovered scientists thought the world’s climate had been unusually stable during the Holocene, the geological epoch that covers the last 11,700 years of Earth’s history.

One lonely molecule…

by Ian Plimmer, Geologist, June 17, 2017

If Australia emits 1.5 per cent of global annual CO2 emissions, 3 per cent of the total annual global emissions are anthropogenic and the atmosphere contains 400 parts per million by volume of CO2, then one molecule in 6.6 million molecules in the atmosphere is CO2 emitted from humans in Australia. This molecule has an atmospheric life of about 7 years before it is removed from the atmosphere by natural sequestration into life and limey sediments.

Hundreds Of Scientific Papers Challenge ‘Global’ Warming

By Kenneth Richard, June 16, 2017 in NoTricksZone

Recently, an article citing over 80 graphs from scientific papers published in 2017 — and another 55 graphs from 2016  — established that modern “global” warming is not actually global in scale, and that today’s warmth is neither unprecedented or remarkable when considering the larger context of natural variability.

Here, an additional 140 non-hockey stick graphs taken from papers published in 2015 and earlier have now been made available.  With this latest installment, graphical temperature reconstructions challenging the conceptualization of global-scale or unprecedented modern warming are rapidly approaching 300.

The Vostok Ice Core: Temperature, CO2 and CH4

by Euan Means, December 12, 2014

In their seminal paper on the Vostok Ice Core, Petit et al (1999) [1] note that CO2 lags temperature during the onset of glaciations by several thousand years but offer no explanation. They also observe that CH4 and CO2 are not perfectly aligned with each other but offer no explanation. The significance of these observations are therefore ignored. At the onset of glaciations temperature drops to glacial values before CO2 begins to fall suggesting that CO2 has little influence on temperature modulation at these times.
