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.

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.

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.

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’.

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.”

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

Comment by Sonja van Renssen
If you’re in the energy business, here is a new manual for you that lays out the essentials of what energy is and how it shapes geopolitics today. Professor and long-time European Commission official Samuele Furfari has condensed his 39 years of experience in the energy sector into a two-volume tome of more than 1,250 pages that goes right from the fundamentals of physics through Britain’s rule of the Middle East to modern day realities such as “Rosatom, the undisputed nuclear leader”, “Biofuels, a subsidised reality”, smart cities and the latest gas discoveries in the Eastern Mediterranean. Energy Post spoke with the author about his new book.

It has long been established in the peer-reviewed scientific literature that naturally-driven fluctuations in the Earth’s surface temperature preceded the rise and fall of carbon dioxide (CO2) concentrations for at least the last 800,000 years.

The sun has looked remarkably blank lately, with few dark cores interrupting the featureless solar disk. This is a sign that Solar Minimum is coming. Indeed, sunspot counts have just reached their lowest level since 2011.

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.

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.

Today marks the 6th day in a row that the sun is blank and the 36th time this year – already more spotless days than all of 2016. In what has turned out to be a historically weak solar cycle (#24), the sun continues to transition away from its solar maximum phase and towards the next solar minimum.

The eminent scientist Stephen Koonin has stated that, ‘Today’s best estimate of the sensitivity [of the atmosphere to the addition of carbon dioxide]… is no different, and no more certain, than it was 30 years ago. And this is despite an heroic research effort costing billions of dollars.’

Arctic amplification is a robust feature of climate response to global warming, with large impacts on ecosystems and societies. A long-standing mystery is that a pronounced Arctic warming occurred during the early 20th century when the rate of interdecadal change in radiative forcing was much weaker than at present. Here, using observations and model experiments, we show that the combined effect of internally generated Pacific and Atlantic interdecadal variabilities intensified the Arctic land warming in the early 20th century.

Last year there were at least 60 peer-reviewed papers published in scientific journals demonstrating that Today’s Warming Isn’t Global, Unprecedented, Or Remarkable..Just within the last 5 months, 58 more papers and 80 new graphs have been published that continue to undermine the popularized conception of a slowly cooling Earth temperature history followed by a dramatic hockey-stick-shaped uptick, or an especially unusual global-scale warming during modern times.

A new global assessment reveals that increases in leaf abundance are causing boreal areas to warm and arid regions to cool. The results suggest that recent changes in global vegetation have had impacts on local climates that should be considered in the design of local mitigation and adaptation plans.

The relative influences of tectonics, continental weathering and seafloor weathering in controlling the geological carbon cycle are unknown. Here we develop a new carbon cycle model that explicitly captures the kinetics of seafloor weathering to investigate carbon fluxes and the evolution of atmospheric CO2 and ocean pH since 100 Myr ago.

The fuel-hungry country has been pursuing the energy source, located at the bottom of oceans and in polar regions, for nearly two decades. China’s minister of land and resources, Jiang Daming, said Thursday that the successful collection of the frozen fuel was “a major breakthrough that may lead to a global energy revolution,” according to state media.
Experts agree that flammable ice could be a game changer for the energy industry, similar to the U.S. shale boom. But they caution that big barriers — both technological and environmental — need to be cleared to build an industry around the frozen fuel, which is also known as gas hydrate.

Water reservoirs created by damming rivers could have significant impacts on the world’s carbon cycle and climate system that aren’t being accounted for, a new study concludes.
The study, conducted by researchers at the University of Waterloo and the Université libre de Bruxelles, appears in Nature Communications. It found that man-made dam reservoirs trap nearly one-fifth of the organic carbon moving from land to ocean via the world’s rivers.

The United States has a broader array of energy options than China does. However, China is innovating and investing heavily in what it has, and some of the transformations it is achieving already are truly impressive.
China’s leaders have made a strategic choice about the direction of the country: They are aiming to shift from an economy based on heavy, polluting industries to one driven by technology and innovation. The political will for this upgrade has roots in both international geostrategic ambitions and domestic popular grievances about lagging standards of living—and it is beginning to bear fruit. In the process, however, vested interests and technical stumbling blocks have wasted resources and acted as a ballast against Chinese progress. China has the potential to do much more, and the international community should push it to achieve that potential.
