The results reveal that a lateral collapse can trigger a significant deflection of deep magma pathways in the crust, favouring the formation of a new eruptive centre within the collapse embayment. Our results have implications for the long-term evolution of intraplate volcanic ocean islands.

Regular readers at Anthony’s Watts Up With That will know that for several years, since July 2013 in fact, I have been trying to publish an analysis of climate model error.
The analysis propagates a lower limit calibration error of climate models through their air temperature projections. Anyone reading here can predict the result. Climate models are utterly unreliable. For a more extended discussion see my prior WUWT post on this topic (thank-you Anthony).

The Magnificent Paris deal was rubbery-theatre, make-of-it-what-you-will, and with rare diligence here is Naturepublishing a paper where a team bothered to check progress. (If only Nature held scientific research as accountable as political deals. MBH98 anyone — where Mann’s hockeystick was accepted by Nature, but not the corrections?)

(…) le gaz américain pourrait bouleverser les équilibres mondiaux, avec des conséquences non moins drastiques que pour le pétrole. Les ressources américaines de gaz sont abondantes et, en juillet 2017, le prix interne a atteint son point le plus bas depuis 12 ans, augurant de sa compétitivité à l’export.

Within this scope, the results reveal a pattern of the climatic effect of desert urbanization with nighttime warming and weaker, but significant daytime cooling. This effect is confined to the urban area and is not sensitive to the size of the city or the detailed land cover types in the surrounding areas. The pattern is identified in both winter and summer.

Electricity Consumers Fully Support Scientists’ Letter to EPA Calling for Immediate Reopening of its GHG Endangerment Finding
Key Points: This Letter from over 60 highly credentialed scientists states that: “We the undersigned are individuals who have technical skills and knowledge relevant to climate science and the GHG Endangerment Finding. We each are convinced that the 2009 GHG Endangerment Finding is fundamentally flawed and that an honest, unbiased reconsideration is in order.”

The annual assessment of global greenhouse gas (GHG) emissions by the JRC and the Netherlands Environmental Assessment Agency (PBL) confirms that CO2 emissions have stalled for the third year in a row.
The report provides updated results on the continuous monitoring of the three main greenhouse gases: carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O).

According to USA Today, one reason for the dramatic rise could be from better reporting and monitoring of the storms.

Tony Abbott may have annoyed the climate change mob with his speech in London (see Diary), but a far more serious problem for that industry is an admission that global temperatures have not been following climate models.
by P. Gosselin, October 2017 in NoTricksZone
(…) It appears that the much larger changes predicted by other models arise from additional water vapor evaporated into the atmosphere and not from the CO2 itself (…)
(…) Assuming a doubling of CO2 by the late 21st century (assuming no positive water vapor feedback), we should likely expect to see no more than about 0.3-0.5°C global surface warming and certainly not the 2-5°C warming that has been projected by the GCMs [global circulation models (…)

Including solar and cloud effects as well as all relevant feedback processes our simulations give an equilibrium climate sensitivity of = 0.7°C (temperature increase at doubled CO2) and a solar sensitivity of = 0.17°C (at 0.1% increase of the total solar irradiance). Then CO2 contributes 40% and the Sun 60% to global warming over the last century.

Physical, mathematical and observational grounds are employed to show that there is no physically meaningful global temperature for the Earth in the context of the issue of global warming. While it is always possible to construct statistics for any given set of local temperature data, an infinite range of such statistics is mathematically permissible if physical principles provide no explicit basis for choosing among them. Distinct and equally valid statistical rules can and do show opposite trends when applied to the results of computations from physical models and real data in the atmosphere. A given temperature field can be interpreted as both “warming” and “cooling” simultaneously, making the concept of warming in the context of the issue of global warming physically ill-posed.

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 !
