Dans un silence remarquable, on vient d’apprendre que les incendies qui ont ravagé la Californie en 2018 ont été causés par des défauts de maintenance dans le réseau électrique et ne devaient rien au réchauffement climatique, rapporte Benoît Rittaud, mathématicien et président de l’Association des climato-réalistes. Tribune.
Calomniez, calomniez, il en restera toujours quelque chose, dit-on. Dans notre monde où l’écologisme est un réflexe pavlovien, ce slogan s’est fait encore plus simple : dès que se produit un drame, toute explication fondée sur le « dérèglement climatique » est présumée correcte. Cette vérité immédiate a alors de bonnes chances de devenir vérité tout court, car qui ira perdre son temps à rétablir les faits après coup, tandis qu’entre-temps tant d’autres drames auront à leur tour « démontré une fois de plus la réalité de la crise ».

Mass spectrometry is essential for research in climate science.
Understanding climate requires having sufficient knowledge about past climate and about the important factors that are influencing climate today, so that reliable models can be developed to predict future climate.
Analytical chemistry enables measurement of the chemical composition of materials, from the amounts of elements and their isotopes in a sample to the identity and concentrations of substances in the most complex biological organisms.
This two-part series covers the application of a powerful analytical chemistry technology — mass spectrometry — to two important areas in climate science:
- Obtaining reliable information about past climate
- Understanding composition and behavior of aerosols, which have a large impact on climate
The examples that are included for each topic were selected out of many published papers on the study of climate using mass spectrometry, partly because they feature a very wide range of types of these instruments. The authors were very helpful in providing me with information on their work.[1]
The technology described in this essay may at times be quite complicated! However, I hope that the results of each study will be understandable.

Ten days ago the journal Science issued an embargoed press release about a forthcoming paper that suggested the warming observed in West Antarctica was due to natural climatic variability.
West Antarctica has always been looked on by alarmists as being the southern example of polar temperature amplification – a phenomenon predicted by most climate change models.
The Arctic temperature amplification is very apparent so there must be an Antarctic equivalent, and there it is.
But while scientists have been well aware that Antarctica is warming asymmetrically, with West Antarctica experiencing more than East Antarctica and frequently attributed to climate change, the underlying causes of this phenomenon have been poorly understood, and the suggestion that West Antarctica may be experiencing natural warming has been suggested before though not taken up very enthusiastically, if at all.
This new paper, “The internal origin of the west-east asymmetry of Antarctic climate change”, expresses the dilemma well.
