THE UN’S DOOMSDAY CLIMATE CLOCK

by GWPF, October 18, 2018 TheWallStreetJournal


In case you hadn’t heard we’re all doomed, yet the world mostly yawned. This is less complacency than creeping scientific and political realism.

The U.N. panel says the apocalypse is nigh—literally. According to its calculations, global carbon emissions must fall 45% by 2030—twice as much as its earlier forecasts—and the world must wean itself entirely off fossil fuels over three decades to prevent a climate catastrophe that will include underwater coastlines and widespread drought and disease.

These reductions are “possible within the laws of chemistry and physics,” said the report’s co-author Jim Skea, and that’s a relief. But he added: “Doing so would require unprecedented changes,” and the report said some methods “are at different stages of development and some are more conceptual than others, as they have not been tested at scale.”

Substantial changes in air pollution across China during 2015 to 2017

by University of Leeds, October 17, 2018 in ScienceDaily


A study by the University of Leeds has examined measurements from more than 1600 locations in China and found that more than 50 per cent of the locations showed a significant decrease in concentrations of sulphur dioxide and fine particulates that make up a large portion of air pollution.

The team used datasets from 2015 to 2017 consisting of hourly assessments of concentrations of Nitrogen Dioxide (NO2), Sulphur Dioxide (SO2), Ozone (O3), and fine particles measuring less than 2.5 μm (PM2.5).

Les limites des lois de la physique dans la transition énergétique

by Alain Préat, 17 octobre 2018, in ScienceClimatEnergie


Bertrand Cassoret a récemment publié un excellent ouvrage [1] sur le sujet. Cet auteur est ingénieur et docteur en génie électrique et s’est lancé sans a priori dans le dédale des ‘promesses’ des énergies vertes en tentant de préciser ce qu’il en est à partir d’une quantification rigoureuse des rendements énergétiques réels. Pourquoi ‘réels’ ? Simplement parce qu’il faut débusquer tout ce qui n’est pas mis en avant (principalement pertes énergétiques cachées) et surtout mettre à plat les ordres de grandeurs du monde de l’énergie. Sa conclusion sera sans appel « même si l’efficacité énergétique est utile et même indispensable, elle ne sera pas suffisante… il est nécessaire de modifier l’usage que l’on fait des appareils consommateurs ». Autre conclusion sans appel « mon objectif n’est pas de critiquer les énergies renouvelables, ni les nécessaires mesures d’efficacité, mais plutôt de montrer qu’elles pèsent bien peu face à l’ampleur des problèmes ».

Oil Production at 100 million bbl/d: “Twin peaks straining the system to the limit”? Or just another day at the office in a highly resilient industry?

by  David Middleton, October 15, 2018 in WUWT


From the International Energy Agency’s Oil Market Report (OMR):

OMR: Twin Peaks

12 October 2018

Both global oil demand and supply are now close to new, historically significant peaks at 100 mb/d, and neither show signs of ceasing to grow any time soon. Fifteen years ago, forecasts of peak supply were all the rage, with production from non-OPEC countries supposed to have started declining by now.

 

Le catastrophisme climatique des années 60 à 80 à l’épreuve des faits

by Cédric Moro, 15 octobre 2018 in MythesMancies&Mathématiques


Les discours alarmistes sur le climat ne datent pas d’hier. Grâce à la numérisation des archives audio-visuelles et à leur mise en ligne sur internet, il est possible aujourd’hui de démentir les prévisions climato-catastrophistes assénées de manière très officielle dans la deuxième moitié du siècle dernier. Beaucoup des déformations de nos discours sur la réalité tendent à puiser leurs racines dans nos représentations mentales du monde. Nous verrons donc que ces représentations alarmistes naissent dans un contexte idéologique nouveau : mutation de l’eugénisme, collapsologisme et décroissance.

IPCC achieves net zero credibility

by Barry Brill, October 14, 2018 in WUWT


The recently released IPCC SR15 reports (at A1) that global warming is likely to reach 1.5°C between 2032 and 2050 and (at B) will probably bring species extinction, weather extremes and risks to food supply, health and economic growth. If we are to avoid this, net CO2 emissions will need to decline by about 45% from 2010 levels by 2030, reaching net zero by 2050 (C1), followed by extensive removals (C5). The required energy investment alone will be $2.4 trillion per year.

Is this possible?

As at 2015, which was not materially different from 2010, more than half the planet’s total CO2 emissions (36Gt) were sourced from just three countries:

Reliable? CRU, NASA, BEST, NOAA Land Temp Data Conflict By Up To 90% (0.8°C), Spawning ‘Large Uncertainty’

by K. Richard, October 8, 2018 in NoTricksZone


A new paper documents “remarkably different” land temperatures from one instrumental data set to another. In some regions there is as much as an 0.8°C conflict in recorded temperature anomalies for CRU, NASA, BEST, and NOAA. The relative temperature trend differences can reach 90% when comparing instrumental records. Consequently, the uncertainty in instrumental temperature trends — “0.097–0.305°C per decade for recent decades (i.e., 1981–2017)” —  is as large or larger than the alleged overall warming trend itself for this period.

Reconstruction of Prehistoric Landfall Frequencies of Catastrophic Hurricanes in Northwestern Florida from Lake Sediment Records

by Kam-biu Liu & Miriam L. Fearn, September 2000,  in QuaternaryResearch


Sediment cores from Western Lake provide a 7000-yr record of coastal environmental changes and catastrophic hurricane landfalls along the Gulf Coast of the Florida Panhandle. Using Hurricane Opal as a modern analog, we infer that overwash sand layers occurring near the center of the lake were caused by catastrophic hurricanes of category 4 or 5 intensity. Few catastrophic hurricanes struck the Western Lake area during two quiescent periods 3400–5000 and 0–1000 14C yr B.P. The landfall probabilities increased dramatically to ca. 0.5% per yr during an “hyperactive” period from 1000–3400 14C yr B.P., especially in the first millennium A.D. The millennial-scale variability in catastrophic hurricane landfalls along the Gulf Coast is probably controlled by shifts in the position of the jet stream and the Bermuda High.

Study: climate was more variable during the last inter-glacial period

by Anthony Watts, October 12, 2018 in WUWT


Century-scale climate variability was enhanced when the Earth was warmer during the Last Interglacial period (129-116 thousand years ago) compared to the current interglacial (the last 11,700 years), according to a new UCL-led study.

The findings, published today in Nature Communications and funded by the Natural Environment Research Council (NERC) and the Australian Research Council (ARC), reveal that the Last Interglacial period was punctuated by a series of century-scale arid events in southern Europe and cold water-mass expansions in the North Atlantic.

Failure of ‘World’s Biggest Solar Project’ in Saudi Arabia Is No Surprise

by Jason Deign, October 2, 2018 in gym


Renewables developers eyeing Saudi Arabia remain wary of the market following the news that the world’s biggest solar project has been canceled.

The $200 billion, 200-gigawatt solar plant planned by SoftBank and the Saudi Public Investment Fund had raised skepticism among developers when it was announced in March, partly because of technical concerns over how it might be integrated into the grid.

The main worry, though, was that the megaproject appeared to have been approved independently of plans for an orderly ramp-up of solar through a tender program managed by the Saudi Renewable Energy Project Development Office (REPDO).

Ocean Temperatures Have Been Rising Since 19thC

by P. Homewood, October 12, 2018 in NotaLotofPeopleKnowThat

The significance of course is that the warming of the oceans began long before any impact from CO2 emissions.

HH Lamb has written extensively about how sea temperatures in the Atlantic fell radically during the LIA. Is the warming trend since then merely a return to earlier conditions?

McIntyre: ‘a reductio ad absurdum of tree ring chronologies as useful temperature proxies’

by A. Watts, October 11, 2018 in WUWT


Steve McIntyre has a look at the “revised” PAGES2K temperature proxy dataset that includes tree rings and river sediments. He finds the usual ridiculous problems from the past, such as upside down data and river sediment accumulations that have more to do with building a dam than climate.

Richard Lindzen Lecture at GWPF: ‘Global Warming for the Two Cultures’

by R. Lindzen, Ocotber2, 208 in A. Watts, WUWT


The climate system

The following description of the climate system contains nothing that is in the least controversial, and I expect that anyone with a scientific background will readily follow the description. I will also try, despite Snow’s observations, to make the description intelligible to the non-scientist.

Conclusion

So there you have it. An implausible conjecture backed by false evidence and repeated incessantly has become politically correct ‘knowledge,’ and is used to promote the overturn of industrial civilization. What we will be leaving our grandchildren is not a planet damaged by industrial progress, but a record of unfathomable silliness as well as a landscape degraded by rusting wind farms and decaying solar panel arrays. False claims about 97% agreement will not spare us, but the willingness of scientists to keep mum is likely to much reduce trust in and support for science. Perhaps this won’t be such a bad thing after all – certainly as concerns ‘official’ science.

There is at least one positive aspect to the present situation. None of the proposed policies will have much impact on greenhouse gases. Thus we will continue to benefit from the one thing that can be clearly attributed to elevated carbon dioxide: namely, its effective role as a plant fertilizer, and reducer of the drought vulnerability of plants. Meanwhile, the IPCC is claiming that we need to prevent another 0.5◦C of warming, although the 1◦C that has occurred so far has been accompanied by the greatest increase in human welfare in history. As we used to say in my childhood home of the Bronx: ‘Go figure’.
