China Gas Output Rises to Record as Coal Production Rebounds

by Bloomberg News, April 17, 2017

China’s natural gas production surged to a record last month and coal output rebounded as economic growth accelerated power use in the world’s largest energy user.

Natural gas production in March rose 8.2 percent from the average of the first two months of the year to a record 13.6 billion cubic meters, according to data Monday from the National Bureau of Statistics. Coal output rose almost 13 percent over the same period to average 9.67 million tons a day, the highest daily level since December, according to Bloomberg calculations based on the data.

Paris climate promises will reduce temperatures by just 0.05°C in 2100 (Press release)

by Bjorn Lomborg, April 2017

The climate impact of all Paris INDC promises is minuscule: if we measure the impact of every nation fulfilling every promise by 2030, the total temperature reduction will be 0.048°C (0.086°F) by 2100.

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.

Satellite Data: Post El Niño Global Surface Cooling Continues… Pause Extends To 20 Years

by P. Gosselin, April 12, 2017

Critical German climate site (WBDE) reports that the earth’s surface is cooling, and presents the latest chart from NCEP. As of April 11, the measured global values continue to decline (black curve) as do the computed values for April 18.

The time-delayed post El Niño cooling is now showing up in the UAH and RSS satellite data.

The subtle origins of surface-warming hiatuses

 by Christopher Hedemann et al., March 17, 2017, Nature

During the first decade of the twenty-first century, the Earth’s surface warmed more slowly than climate models simulated1. This surface-warming hiatus is attributed by some studies to model errors in external forcing2, 3, 4, while others point to heat rearrangements in the ocean5, 6, 7, 8, 9, 10 caused by internal variability, the timing of which cannot be predicted by the models1. However, observational analyses disagree about which ocean region is responsible11, 12, 13, 14, 15, 16

Burden of proof: A comprehensive review of the feasibility of 100% renewable-electricity systems

by B.P. Heard et al., 2017

An effective response to climate change demands rapid replacement of fossil carbon energy sources. This must occur concurrently with an ongoing rise in total global energy consumption. While many modelled scenarios have been published claiming to show that a 100% renewable electricity system is achievable, there is no empirical or historical evidence that demonstrates that such systems are in fact feasible. Of the studies published to date, 24 have forecast regional, national or global energy requirements at sufficient detail to be considered potentially credible. We critically review these studies using four novel feasibility criteria for reliable electricity systems needed to meet electricity demand this century

The Antarctic Peninsula: No Longer the Canary in the Coal Mine for Climate Alarmists

by M. Oliva et al., 2017

In light of all the above, the evidence is clearly mounting against those who point to warming on the Antarctic Peninsula as proof of CO2-induced global warming. For in the most incredible manner, warming trends that were once among the highest recorded on earth have slowed and even reversed to show cooling.

New Paper: Northern Hemisphere Temperatures Rose 4–5°C Within ‘A Few Decades’ 14,700 Years Ago

By Kenneth Richard , April 2017

According to a new paper, the Bølling Warming event 14,700 years ago raised the surface temperature for the entire Northern Hemisphere by 4 to 5°C within a few decades.  This is a hemispheric warming rate of approximately 2.0°C per decade, which is 40 times faster than the 0.05 °C per decade global warming rate since 1850 (and 1998).

The Art and Science of Climate Model Tuning

by Hourdin et al., March 2017,

Bulletin of the American Meteorological Society

We also discuss the challenges and opportunities in applying so-called objective methods in climate model tuning. We discuss how tuning methodologies may affect fundamental results of climate models, such as climate sensitivity. The article concludes with a series of recommendations to make the process of climate model tuning more transparent.

Claim: Next 10 years critical for achieving climate change goals

by Anthony Watts, April 13, 2007

Carbon dioxide (CO2) and other greenhouse gases in the atmosphere can be reduce in two ways–by cutting our emissions, or by removing it from the atmosphere, for example through plants, the ocean, and soil.

The historic Paris Agreement set a target of limiting future global average temperature increase to well below 2°C and pursue efforts to even further limit the average increase to 1.5°C above pre-industrial levels. Yet the timing and details of these efforts were left to individual countries.

Methane seeps in the Canadian high Arctic

by Geological Society of America, April 13, 2017

in ScienceDaily

Cretaceous climate warming led to a significant methane release from the seafloor, indicating potential for similar destabilization of gas hydrates under modern global warming. A field campaign on the remote Ellef Ringnes Island, Canadian High Arctic, discovered an astounding number of methane seep mounds in Cretaceous age sediments.

Afrique du Sud : les enjeux du gaz de schiste

by Professeur François Lafargue, Avril 2017

in Connaissance des Energies

La puissance économique et industrielle de l’Afrique du Sud classe naturellement ce pays au premier rang des consommateurs d’énergie en Afrique. L’Afrique du Sud consomme 30 % de l’énergie primaire et 37 % de l’électricité produites sur le continent africain. Les fréquents dysfonctionnements des infrastructures d’électricité constatés ces dernières années ont placé la question de l’énergie au centre des débats publics.
