Though mass extinctions wiped out staggeringly high numbers of species, they barely touched the overall ‘functional’ diversity — how each species makes a living, be it filtering phytoplankton or eating small crustaceans, burrowing or clamping onto rocks.

Germany’s utopian dream of transforming itself into the world’s green powerhouse is collapsing as its political and media establishment is mugged by reality. The country’s climate obsession has turned into one of the country’s biggest political and economic handicaps, making Germany almost ungovernable.

La fermeture des centrales nucléaires belges pourrait entraîner une augmentation de 50% des émissions de CO2 liées à la production d’énergie d’ici 2030, selon le professeur d’économie Johan Albrecht (UGent – Université de Gand), qui est également membre de l’institut de réflexion Itinera. Cela alors que le gouvernement fédéral et les entités fédérées doivent négocier dans les semaines à venir le Pacte énergétique, qui doit fixer l’avenir de la production d’électricité en Belgique.

Prologue: I have been writing recently about Sea Level Rise, both as particular local examples ( Guam, Canton, Miami, New York, and NY/NJ ) and in the series SEA LEVEL: Rise and Fall, of which this is the fourth installment.
Series Take Home Messages:
Overall, the seas have been rising, slowly and inexorably, since the end of the last Ice Age, with some blips and bumps along the way. In general, they will continue to do so for the foreseeable future — at somewhere between 4-12 inches [10-30cm] per century. This rate is an imminent threat to populated areas built nominally at today’s existing sea level.

Science is hard. Some easy problems you can solve by hard work, if you are in the right place at the right time and have the right skills. Hard problems take the combined effort of multiple groups looking at the problem, publishing results and finding fault with eachother’s work, until hopefully no-one can find any more problems. When problems are hard, you may have to publish something that even you don’t think is right, but that might advance the discussion.
The calculation of an unbiased sea surface temperature record is a hard problem. Historical sea surface temperature observations come from a variety of sources, with early records being measured using wooden, canvas or rubber buckets (figure 1), later readings being taken from engine room intakes or hull sensors, and the most recent data coming from drifting buoys and from satellites.

The England & Wales Precipitation Series has now been updated for last year.
Precipitation totalled 952mm during the year, slightly above the series average of 918mm. In ascending order, 2017 ranked 158th.
There seems to be little evidence of any real trends. Whatever trend can be winkled out of the numbers will likely be too small to notice, and swamped by the natural variability in the data.
The wettest years remain 1872 and 1768. The driest were 1788 and 1921.

Climate Myths: We keep reading about how the extreme weather of 2017 is the “new normal” thanks to global warming — even if the weather in question is frigid air. But the data don’t show any trend in extreme weather events in the U.S. for decades. Science, anyone?

The geopolitical risks to the United States’ oil supply are the lowest since the early 1970s, due to fracking, climate action and a more diverse global supply, according to a new paper. America’s energy prosperity contrasts with a more fraught period for energy-exporting countries where geopolitical challenges have been compounded by fiscal stress and rising domestic energy demand, the authors said.

U.S. Secretary of the Interior Ryan Zinke today announced the next step for responsibly developing the National Outer Continental Shelf Oil and Gas Leasing Program (National OCS Program) for 2019-2024, which proposes to make over 90 percent of the total OCS acreage and more than 98 percent of undiscovered, technically recoverable oil and gas resources in federal offshore areas available to consider for future exploration and development. By comparison, the current program puts 94 percent of the OCS off limits. In addition, the program proposes the largest number of lease sales in U.S. history.

Record snowfall, a “bomb cyclone” and cold Arctic air have once again stirred up the debate over global warming’s impact on winter weather.
Some climate scientists are pointing the finger at manmade global warming as a culprit behind recent wintry weather, but there’s not a lot of evidence or agreement that global warming is currently driving extreme cold and snow (…)

Contrary to expectations, climate scientists continue to report that large regions of the Earth have not been warming in recent decades.
According to Dieng et al. (2017), for example, the global oceans underwent a slowdown, a pause, or even a slight cooling trend during 2003 to 2013. This undermines expectations from climate models which presume the increase in radiative forcing from human CO2 emissions should substantially increase ocean temperatures.
The authors indicate that the recent trends in ocean temperatures “may just reflect a 60-year natural cycle“, the AMO (Atlantic Multidecadal Oscillation), and not follow radiative forcing trends.

U.S. crude oil production is flirting with record highs heading into the new year, thanks to the technological nimbleness of shale oil drillers .
The current abundance has erased memories of 1973 gas lines, which raised pump prices dramatically, traumatizing the United States and reordering its economy. In the decades since, presidents and politicians have made pronouncements calling for U.S. energy independence.

The indefatigable Roy Spencer at the University of Alabama at Huntsville is the first to declare the global temperature anomaly for December 2017. As Fig. 1 shows, in the 39 years 1 month from December 1978 to December 2017, the planet has warmed by half a Celsius degree. But that is equivalent to 1.28 C°/century, or little more than one-third of the 3.3 C°/century predicted with “substantial confidence” by IPCC in 1990 and also by the fifth-generation general-circulation models of the Climate Model Intercomparison Project in 2013.

Determining magnitudes of sea surface temperature variability is important for attributing past and predicting future changes in climate, and generally requires the use of proxies to constrain multidecadal and longer timescales of variability. We report a multiproxy estimate of sea surface temperature variability that is consistent between proxy types and with instrumental estimates but strongly diverges from climate model simulations toward longer timescales. At millennial timescales, model−data discrepancies reach two orders of magnitude in the tropics, indicating substantial problems with models or proxies, or both, and highlighting a need to better determine the variability of sea surface temperatures.

We evaluate different hypotheses of the origin of the Little Ice Age, focusing on the long-term response of Arctic sea ice and oceanic circulation to solar and volcanic perturbations. We analyze the Last Millennium Ensemble of climate model simulations carried out with the Community Earth System Model at the National Center for Atmospheric Research. We examine the duration and strength of volcanic perturbations, as well as initial and boundary conditions such as the phase of the Atlantic Multidecadal Oscillation, and their impact on decadal to multi-centennial perturbations of the cryospheric, oceanic, and atmospheric components of the climate system.

In the last 12 months, 150 graphs from 122 peer-reviewed scientific papers have been published that 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.
Yes, some regions of the Earth have been warming in recent decades or at some point in the last 100 years.
Some regions have been cooling for decades at a time.
And many regions have shown no significant net changes or trends in either direction relative to the last few hundred to thousands of years.
Succinctly, then, scientists publishing in peer-reviewed journals have increasingly affirmed that there is nothing historically unprecedented or remarkable about today’s climate when viewed in the context of long-term natural variability.
