Video: analysis of NASA data shows modern temperature trends are not unusual
by Michael Thomas c/o Anthony Watts, May 10, 2017
An important aspect of the climate change debate can be summed up like this: “One position holds that medieval warm temperatures reached levels similar to the late twentieth century and maintained that the LIA was very cold, while another position holds that past variability was less than present extremes and that the temperature rise of recent decades is unmatched”. This video challenges whether the rise of recent decades is unmatched.
Quelles perspectives pour la politique pétrolière américaine ?
by Olivier Appert, Président du Conseil Français de l’Energie
in Connaissance des Energies, 10 mai 2017
Depuis la découverte du colonel Drake en 1859, le pétrole a joué de façon continue un rôle majeur dans la politique économique américaine et sur le plan international, il a été un outil clé du leadership américain. Au fil du temps, cette politique a dû composer avec une modification des rapports de force sur le marché pétrolier. La révolution récente des hydrocarbures non conventionnels a été un game changer majeur. Au fond, la politique pétrolière du nouveau président américain n’est qu’un retour aux sources.

MIT atmospheric science professor Richard Lindzen suggests that many claims regarding climate change are exaggerated and unnecessarily alarmist.
Recent pause in the growth rate of atmospheric CO2 due to enhanced terrestrial carbon uptake
by Keenan et al., November 8, 2016, Nature
Terrestrial ecosystems play a significant role in the global carbon cycle and offset a large fraction of anthropogenic CO2 emissions. The terrestrial carbon sink is increasing, yet the mechanisms responsible for its enhancement, and implications for the growth rate of atmospheric CO2, remain unclear.

Jim McIntosh , David Mulberry and 2 others posted in Air-Climate-Energy (Jim McIntosh 9 May at 11:18): Reposting because those AGW alarmists hate this report. Yes, plants are doing it better than any carbon tax and they do it for free… as long as we don’t cut them down. You’d think we’d learn by now that managing climate comes back to how we have mismanaged the planet’s forests.
Methane-munching microbes living in the deep biosphere for 400 million years: An analogue for extra-terrestrial life
by Linnaeus University, May 9, 2017 in ScienceDaily
-
It is becoming more and more appreciated that a major part of the biologic activity is not going on at the ground surface, but is hidden underneath the soil down to depths of several kilometres in an environment coined the “deep biosphere”. Studies of life-forms in this energy-poor system have implications for the origin of life on our planet and for how life may have evolved on other planets, where hostile conditions may have inhibited colonization of the surface environment. The knowledge about ancient life in this environment deep under our feet is extremely scarce.
Where does all Earth’s gold come from? Precious metals the result of meteorite bombardment, rock analysis finds
by University of Bristol, September 9, 2011 in ScienceDaily
-
Ultra high precision analyses of some of the oldest rock samples on Earth provides clear evidence that the planet’s accessible reserves of precious metals are the result of a bombardment of meteorites more than 200 million years after Earth was formed.
Oldest evidence of life on land found in 3.48 billion-year-old Australian rocks
by UNSW Sydney, May 9, 2017 in ScienceDaily
Fossils discovered by UNSW scientists in 3.48 billion year old hot spring deposits in the Pilbara region of Western Australia have pushed back by 580 million years the earliest known existence of microbial life on land.
he Pilbara deposits are the same age as much of the crust of Mars, which makes hot spring deposits on the red planet an exciting target for our quest to find fossilised life there.”
Snow covers Moscow ahead of V-Day parade, on track to break 1922 precipitation record (PHOTOS)
Winter, apparently, does not want to step back and let spring in as May snow has once again covered the Russian capital ahead of the annual V-Day parade. Meteorologists say May 2017 is on track to break the precipitation record from 1922.
“Storms of such power in Moscow take place once in 30-35 years,” Evgency Tishkovets from the Fobos weather monitoring centre told local Govorit Moskva radio, adding that it is possible that this May can break an absolute record from 1922.
The Impacts of Urban Heat Islands on Natural Warming Trends
by Quereda et al., 2016
“on comparing the temperature of urban areas and rural areas, various researchers have concluded that the urban effect could account for between 40% and 80% of the observed thermal trend in the last few decades,”
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

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.

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
NEW STUDY CONFIRMS: THE WARMING ‘PAUSE’ IS REAL AND REVEALING
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.
A new picture of the last ice age
by Bergen University, March 17, 2016
in ScienceDaily
At the peak of the last ice age, a vast ice sheet covered northern Europe, spanning from the British Isles, across Scandinavia and into Russia in the east and the Barents Sea in the north. A new reconstruction of this ice sheet shows the interaction between climate and glaciers — how the ice sheet grows and retreats
