Extreme temperatures in Southeast Asia caused by El Niño and worsened by global warming

by K. Thirumalai et al., June 6, 2017, in Nature Communication


In April 2016, southeast Asia experienced surface air temperatures (SATs) that surpassed national records, exacerbated energy consumption, disrupted agriculture and caused severe human discomfort. Here we show using observations and an ensemble of global warming simulations the combined impact of the El Niño/Southern Oscillation (ENSO) phenomenon and long-term warming on regional SAT extremes. We find a robust relationship between ENSO and southeast Asian SATs wherein virtually all April extremes occur during El Niño years.

Threshold in North Atlantic-Arctic Ocean circulation controlled by the subsidence of the Greenland-Scotland Ridge

by Michael Stars et al., June 5, 2017 in Nature Communication


High latitude ocean gateway changes are thought to play a key role in Cenozoic climate evolution. However, the underlying ocean dynamics are poorly understood. Here we use a fully coupled atmosphere-ocean model to investigate the effect of ocean gateway formation that is associated with the subsidence of the Greenland–Scotland Ridge. We find a threshold in sill depth (50 m) that is linked to the influence of wind mixing.

CLIMATE ALARMISTS WON’T ADMIT THEY ARE WRONG

by Clives James, The Australian in GWPF, June 6, 2017


Actually, a more illustrative starting point for the theme of the permanently imminent climatic apocalypse might be taken as August 3, 1971, when The Sydney Morning Herald announced that the Great Barrier Reef would be dead in six months.

After six months the reef had not died, but it has been going to die almost as soon as that ever since, making it a strangely durable emblem for all those who have wedded themselves to the notion of climate catastrophe.

Paris climate promises will reduce temperatures by just 0.05°C in 2100

by Bjorn Lomborg, June 2017

Even if we assume that these promises would be extended for another 70 years, there is still little impact: if every nation fulfills every promise by 2030, and continues to fulfill these promises faithfully until the end of the century, and there is no ‘CO₂ leakage’ to non-committed nations, the entirety of the Paris promises will reduce temperature rises by just 0.17°C (0.306°F) by 2100.

Big rigs pave way for second shale oil boom

by Collin Eaton, May 27, 2017 in Houston Chronicle


Drillers have mastered feat of pumping more at less cost

On a drilling rig towering above quiet cattle farms in Southeast Texas, Eric Williams perched inside the cabin of the 16-story machine, twisting a pair of joysticks to guide a gigantic wrench roaring into action, drowning out every sound as it reached for a 1,500-pound pipe emerging from the earth – pipe that soon will feed oil into a second shale boom.

New Papers Show Solar Activity Impacts ENSO, Refuting Claims Sun Has Little Impact On Climate

by P. Gosselin, May 28, 2017


In a joint US-German study, seven scientists recently tried to discredit the sun’s impact on climate. On April 19, 2017, Guoyong Wen and colleagues published a modeling study in the Journal of Space Weather and Space Climate, which suggested a maximum solar-dependent share of 0.1°C on the temperature development over the past 400 years. Here the scientists relied on the old, well-known trick of using the Little Ice Age as the starting.

 

US Summers Are Getting Much Cooler

by Tony Heller, June 3, 2017


Summer is here, and climate alarmists are about to bombard us with claims that global warming is going to burn us up. The data shows the exact opposite. There are 693 USHCN stations which were active in both 1920 and 2016. I ran statistics on this stable group of stations.

The average summer maximum temperature in the US is down about one degree since the 1920’s.

Densely Aggregated Corals Maintain Calcification Under Ocean Acidification Conditions

by N.R. Evensen and P.J. Edmunds, 2017, J. Exp. Biology


Regardless of the actual mechanism responsible for the densely aggregated corals to maintain calcification rates in the face of ocean acidification, the study of Evensen and Edmunds, in their words, offers “a compelling case for differential densities of branching coral colonies (i.e. aggregation types) mediating the sensitivity of coral communities in at least some habitats” and it further supports “recent indications that neighboring organisms, such as conspecific coral colonies in the present example, can create small-scale refugia from the negative effects of ocean acidification” And that is more good news for those concerned about the future health of these important marine ecosystems.

Climate Change: The Facts 2017

by Jennifer Marohasy, June3, 2017


Important new book coming out  …

Contributors to Climate Change: The Facts 2017 do not conform to a unitary view.   As I explain in the book’s introduction:

“An advantage of my approach in the compiling of the chapters for this book – an approach where there has been no real attempt to put everything into neat boxes – is that there are many surprises. I am referring to the snippets of apparently anomalous information scattered through the chapters. These can, hopefully, one day, be reconciled. As this occurs, we may begin to see the emergence of a coherent theory of climate – where output from computer-simulation models bears some resemblance to real-world measurements that have not first been ‘homogenised’.

 

 

LES EPOUVANTABLES CONSEQUENCES DU CHANGEMENT CLIMATIQUE.

by Jo Moreau, Belgotopia, June 2, 2017


“Ceux qui me font l’honneur (et le plaisir) de suivre ma page Facebook “belgotopia” suivent ma rubrique : “Dans l’hilarante série, les délires climatiques” dans laquelle je distille à doses homéopathiques toutes les épouvantables conséquences du réchauffement climatique. Celles-ci sont publiées soit dans des médias, soit dans des revues scientifiques dont on ne peut mettre le sérieux en doute.

Etant arrivé au centième, j’en fais ici une compilation. J’ en ai encore un nombre considérable en réserve !”

Stony corals more resistant to climate change than thought

by Rutgers University, June1, 2017 in SienceDaily


Stony corals may be more resilient to ocean acidification than once thought, according to a Rutgers University study that shows they rely on proteins to help create their rock-hard skeletons.

“The bottom line is that corals will make rock even under adverse conditions,” said Paul G. Falkowski, a distinguished professor who leads the Environmental Biophysics and Molecular Ecology Laboratory at Rutgers University-New Brunswick. “They will probably make rock even as the ocean becomes slightly acidic from the burning of fossil fuels.”

A Holocene Temperature Reconstruction Part 1: the Antarctic

by Andy May, June1, 2017


The Marcott, et al. 2013 worldwide reconstruction has its problems, but many of the proxies used in the reconstruction are quite good and very usable.

The Antarctic reconstruction created here is comparable to previous temperature reconstructions, especially those focusing on eastern Antarctica. It shows two climatic optima, one from 11500 BP to 9000 BP and another from 6000 BP to 3000 BP. In eastern Antarctica, using our proxies, the later optimum is warmer. But, in other areas the earlier optimum is warmer, however, the difference is small
