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.

Now, people often discuss procedures like “removing the effects of the El Nino from the global temperature record”. What they mean is that they have noted the similarity between the temperature of the NINO3.4 region and the global temperature. Figure 1 shows that relationship as seen in the CERES data.

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.

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 ».
Le texte en français de cette conférence (traduction de Camille Veyres) est accessible ici.

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 ?

We conclude that model overestimation of tropospheric warming in the early twenty-first century is partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations.

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 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 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.

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.

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.

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

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.

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.
