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.

The peer-reviewed paper is published in the upcoming issue of Global Policy journal (November 2015). You can access the article online here.

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.

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’.

“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 !”

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

Acceleration in European Mean Sea Level? A New Insight Using Improved Tools

by Phil J. Watson, Journal of Coastal research, May 2017

Key findings are that at the 95% confidence level, no consistent or compelling evidence (yet) exists that recent rates of rise are higher or abnormal in the context of the historical records available across Europe, nor is there any evidence that geocentric rates of rise are above the global average. It is likely a further 20 years of data will distinguish whether recent increases are evidence of the onset of climate change–induced acceleration.

Uncertainty about the Climate Uncertainty Monster

by Judith Curry, May 19, 2017

The many dimensions of the climate uncertainty monster.

Bret Stephens’ climate change op-ed of several weeks ago Climate of Complete Certainty spawned a number of articles related to uncertainty and climate change.

Andy Revkin’s article in response was titled There are lots of climate uncertainties.  Let’s acknowledge and plan for them with honesty.    Revkin even mentions the Uncertainty Monster and Jeroen van der Sluijs.
