There Has Been No ‘Global’ Warming In The Southern Hemisphere, Equatorial Regions

by Kenneth Richard, May 4, 2017

According to overseers of the long-term instrumental temperature data, the Southern Hemisphere record is “mostly made up”.  This is due to an extremely limited number of available measurements both historically and even presently from the south pole to the equatorial regions.

Below is an actual e-mail conversation between the Climate Research Unit’s Phil Jones and climate scientist Tom Wigley.  Phil Jones is the one who is largely responsible for making up the 1850-present temperature data for the Met Office in the UK (HadCRUT).


They are diseases hidden in ice, and they are waking up

by Jasmin Fox-Skelly, BBC, May 4, 2017

Throughout history, humans have existed side-by-side with bacteria and viruses. From the bubonic plague to smallpox, we have evolved to resist them, and in response they have developed new ways of infecting us.

However, what would happen if we were suddenly exposed to deadly bacteria and viruses that have been absent for thousands of years, or that we have never met before?

Taking The Economist to Task for Unfounded Climate Catastrophe Fearmongering

by   Dr. John D. Harper, FGSA,FGAC, PGeol., former director of the Geological Survey of Canada © May 2017

I have recently been asked to comment on three articles published in The Economist. My background for such a response is as a Professor of Petroleum Geology and Sedimentology (ret.), a former Director-Energy for the Geological Survey of Canada, a former researcher in industry, and as an academic researcher on sea level changes and climate documentation through geologic time, Natural Resources of the Future and a couple of decades of studies in the Arctic.

Battered Earth revived by mineral weathering after mass extinction

by University of Tromso, May 5, 2017 in ScienceDaily

Bedrock of Earth got severely beaten up by hothouse climate conditions during one of planet’s mass extinctions some 200 million years ago. But the process also allowed life to bounce back.

The hothouse conditions of this mass extinction caused oceans to eventually become depleted of oxygen, and thus become unbearable to live in. But weathering of silicate in the bedrock of Pangea, and subsequent formation of carbonate, tied up the CO2 into the minerals, slowly removing the greenhouse gas from the atmosphere.

New theory on how Earth’s crust was created

by McGill University , EPSL,  May 5, 2017, in ScienceDaily

Conventional theory holds that all of the early Earth’s crustal ingredients were formed by volcanic activity. Now, however, earth scientists have published a theory with a novel twist: some of the chemical components of this material settled onto Earth’s early surface from the steamy atmosphere that prevailed at the time.

More than 90% of Earth’s continental crust is made up of silica-rich minerals, such as feldspar and quartz. But where did this silica-enriched material come from? And could it provide a clue in the search for life on other planets?

Current Surface Mass Budget of the Greenland Ice Sheet

by DMI (Danish Meteorological Institute), May, 2017

Here you can follow the daily surface mass balance on the Greenland Ice Sheet. The snow and ice model from one of DMI’s climate models is driven every six hours with snowfall, sunlight and other parameters from a research weather model for Greenland, Hirlam-Newsnow.

EU trend of CO2 reduction seems to have stopped

by Peter Teffer, May 4, 2017 in euobserver

The EU’s statistical agency Eurostat announced Thursday (4 May) that CO2 emissions resulting from the EU’s energy use have “slightly decreased” in 2016, compared to the year before.

But Eurostat’s press release did not mention that the small decrease has not made up for the small increase in CO2 emissions the year before, and that more CO2 was emitted in 2016 than in 2014.

A propos de l’article « Réchauffement climatique » paru dans « Science … & pseudo-sciences »

by Jean-Claude Pont, c/o Uskek, 3 mai 2017

Jean-Claude Pont écrit au rédacteur en chef de « Science … & pseudo-sciences », à propos de l’article « réchauffement climatique » paru dans le numéro 317 de la revue. Il entend rectifier ce qu’il tient pour « des manquements importants, parfois des ambiguïtés, voulues ou inconscientes ».

Earth probably began with a solid shell

by University of Maryland, in Nature, February 27, 2017

in ScienceDaily

New research suggests that plate tectonics began later in Earth’s history

But new research suggests that this was not always the case. Instead, shortly after Earth formed and began to cool, the planet’s first outer layer was a single, solid but deformable shell. Later, this shell began to fold and crack more widely, giving rise to modern plate tectonics.

Miocene flooding events of western Amazonia

by Carlos Jaramillo et al., Science Advances, May 3, 2017

The Neogene history of Amazonia is essential for understanding the evolution of the rainforest and associated fauna living in one of the most diverse places on Earth. A central question about our understanding of Amazonia remains unsolved: Did continental-scale marine flooding occur in western Amazonia during the Neogene? Miocene marine transgressions in the continental interior would have had a profound effect on the diversification and structuring of both terrestrial and aquatic Neotropical communities


by Dr David Whitehouse, GWPF Science Editor, May 4, 2017

A new paper has been published in the Analysis section of Nature called Reconciling controversies about the ‘global warming hiatus.’ It confirms that the ‘hiatus’ or ‘pause’ is real. It is also rather revealing.

It attempts to explain the ‘Pause’ by looking into what is known about climate variability. They say that four years after the release of the IPCC AR5 report, which contained much about the ‘hiatus’ it is time to see what can be learned.

One could be a little sarcastic in saying why would Nature devote seven of its desirable pages to an event that some vehemently say never existed and maintain its existence has been disproved long ago. Now, however, as the El Nino spike of the past few years levels off, analysing the ‘pause’ seems to be coming back into fashion.

Onset and ending of the late Palaeozoic ice age triggered by tectonically paced rock weathering

by Yves Goddéris et al., April 10, 2017, Nature Geoscience

The onset of the late Palaeozoic ice age about 340 million years ago has been attributed to a decrease in atmospheric CO2 concentrations associated with expansion of land plants, as plants both enhance silicate rock weathering—which consumes CO2—and increase the storage of organic carbon on land. However, plant expansion and carbon uptake substantially predate glaciation

Rise of Earth’s atmospheric oxygen controlled by efficient subduction of organic carbon

by M. Duncan and R. Dasgupta, April 25, 2017, Nature Geoscience

We suggest that immobilization of organic carbon in subduction zones and deep sequestration in the mantle facilitated the rise (~103–5 fold) and maintenance of atmospheric oxygen since the Palaeoproterozoic and is causally linked to the Great Oxidation Event. Our modelling shows that episodic recycling of organic carbon before the Great Oxidation Event may also explain occasional whiffs of atmospheric oxygen observed in the Archaean.

China’s coal-fired power generation surprises naysayers

by Michael Cooper, May 2, 2017

Anyone with doubts about China’s demand for energy including for thermal coal needed to sustain its gigantic economy should cast their eyes over the latest statistics for power generation from Beijing’s National Statistics Bureau.

These data are a treasure trove in terms of revealing trends in China’s energy production and appetite for thermal coal sourced from both inside China and from imports shipped from countries including, Australia, Indonesia and Russia.
