Future global climate projections have been put on more solid empirical ground, thanks to new measurements of the production rates of atmospheric aerosol particles by CERN’s Cosmics Leaving OUtdoor Droplets (CLOUD) experiment

In stark contrast to the sharp decline in Arctic sea ice, there has been a steady increase in ice extent around Antarctica during the last three decades, especially in the Weddell and Ross seas. In general, climate models do not to capture this trend and a lack of information about sea ice coverage in the pre-satellite period limits our ability to quantify the sensitivity of sea ice to climate change and robustly validate climate models

Le jury pensait, bien sûr, désigner plus tôt le vainqueur de septembre 2017 de la propagande climatique. Il demande pardon aux lecteurs pour avoir à ce point aiguisé leur impatience, mais dispose toutefois d’une circonstance fortement atténuante : à quel irrépressible élan a-t-il fallu faire face !
Quelle fougue des compétiteurs, nouveaux comme anciens, a déferlé ce mois-ci, rendant le choix final tout simplement impossible !

Satellite measurements of Antarctic sea ice do not go back even 40 years. That’s not very much, especially when we consider that many natural climate cycles have periods of 60 years and more.
Luckily we have the field of climate reconstruction. Using historical documents and sediment cores, the development of ice cover can be estimated. In November, 2016, Tom Edinburg and Jonathan Day examined shipping log books from the time of Antarctic explorers and published on ice extent in The Cryosphere (…)

A recently highlighted paper published by atmospheric scientists Scafetta et al., (2017) featured a graph (above) documenting post-2000 trends in the published estimates of the Earth’s climate sensitivity to a doubling of CO2 concentrations (from 280 parts per million to 560 ppm).

This is interesting. It appears that a “pause” has developed in global sea levels. For two years, since July 2015, there has been no sustained increase in global sea level, in fact, it appears to have actually fallen a bit. This graph, provided by NASA’s Global Climate Change website, tells the story:

October 15 used to be a warm day in the US, but temperatures have plummeted over the past century.

Temperature and Water Level (MSL) are two hot topic measurements being widely bandied about and vast sums of money are being invested in research to determine whether, on a global scale, these physical quantities — Global Average Temperature and Global Mean Sea Level — are changing, and if changing, at what magnitude and at what rate. The Global Averages of these ever-changing, continuous variables are being said to be calculated to extremely precise levels — hundredths of a degree for temperature and millimeters for Global Sea Level — and minute changes on those scales are claimed to be significant and important.

Dans quelle mesure les émissions anthropiques qui s’élèvent à 9 Giga Tonnes par an (dont 1,5 dues au changement d’utilisation des sols) perturbent le cycle du carbone contribuant à l’augmentation de la concentration de CO2 dans l’atmosphère?
