Canada’s tar sands, which contain the planet’s third-largest oil reserves, were a prized possession for global energy companies when crude was trading above $100 a barrel. But since prices fell to $50 in 2015, where they have lingered, Royal Dutch Shell, ConocoPhillips, and Marathon Oil have unloaded their holdings amid concerns that these capital-intensive projects would struggle to turn a profit.
(…) In recent earnings announcements, Suncor and rival Cenovus Energy Inc. said they can now sustain production with oil at $40 a barrel without jeopardizing the dividend they pay shareholders.

In the press release for a newly published and controversial peer-reviewed scientific paper, Australian scientist Dr. Jennifer Marohasy unveiled one of climate science’s better-kept secrets.
She and her colleagues are well aware that the post-1940s Northern Hemisphere (NH) proxy evidence from tree-rings, bore holes, pollen, etc., consistently fails to affirm sharply rising temperatures from the late 20th century onwards.

Since 2005, the U.S. has added more than 120,000 gas wells, mainly in Texas, Pennsylvania, Oklahoma and Colorado. In 2015, there were 555,000 in total.
Those onshore wells have not just made up for declining offshore production, they have handily exceeded it. Offshore gas is now only 4 percent of total U.S. withdrawals. Texas, Pennsylvania, Oklahoma and Colorado are 53 percent of all production.

Way back in February, Global Weather Oscillations (GWO) veteran meteorologist David Dilley predicted that the 2017 Atlantic hurricane season would be “the most dangerous and costliest in 12 years for the United States.” (…)

Indeed, it could be that the last 20-years of temperature recordings by the Bureau will be found not fit for purpose, and will eventually need to be discarded. This would make for a rather large hole in the calculation of global warming – given the size of Australia.

Changes in the sources of nitrogen and the composition of the phytoplankton community are more likely to account for the differences seen in the isotope data, Huckstadt said. “It looks more like a shift at the base of the food web, probably related to the transition from the Little Ice Age to current conditions, causing changes in the phytoplankton community,” he said.

Dans la lutte que mènent nos villes contre la pollution urbaine, on perçoit la recherche désespérée de solutions alternatives aux véhicules conventionnels. C’est le cas en particulier pour les particules fines, même s’il est de bon ton de passer sous silence que le chauffage contribue aussi largement à cette pollution….

To date, about 1.5 million species have been formally described in the scientific literature, most of them insects. Proportionally, bacteria comprise less than 1% of all described species.

In a new paper published in The Quarterly Review of Biology (September 2017), researchers from the University of Arizona have estimated that there are roughly 2 billion living species on Earth, over a thousand times more than the current number of described species.

Banded iron formations were a prevalent feature of marine sedimentation ~3.8–1.8 billion years ago and they provide key evidence for ferruginous oceans. The disappearance of banded iron formations at ~1.8 billion years ago was traditionally taken as evidence for the demise of ferruginous oceans, but recent geochemical studies show that ferruginous conditions persisted throughout the later Precambrian, and were even a feature of Phanerozoic ocean anoxic events.

Human appropriation of land for agriculture has greatly altered the terrestrial carbon balance, creating a large but uncertain car- bon debt in soils. Estimating the size and spatial distribution of soil organic carbon (SOC) loss due to land use and land cover change has been difficult but is a critical step in understand- ing whether SOC sequestration can be an effective climate mitigation strategy.

A natural global warming event that took place 56 million years ago was triggered almost entirely by volcanic eruptions that occurred as Greenland separated from Europe during the opening of the North Atlantic Ocean,
…The amount of carbon released during this time was vast—more than 30 times larger than all the fossil fuels burned to date and equivalent to all the current conventional and unconventional fossil fuel reserves we could feasibly ever extract.” Ridgwell said.
An unexpected finding was that enhanced organic matter burial was important in ultimately sequestering the released carbon and accelerating the recovery of the Earth’s ecosystem without massive extinctions.

Trends in major-floods from 1204 sites in North America and Europe are assessed.
Trends based on counting exceedances of flood thresholds for groups of gauges.
The number of significant trends was about the number expected due to chance alone.
Changes in the frequency of major floods are dominated by multidecadal variability.

Here’s another blow to the global warming alarmist scientists, who have been claiming that the Medieval Warm Period was a local, North Atlantic phenomenon, and did not really exist globally. What follows is a report on yet another paper contradicting this now worn out claim.

As the Houston flood disaster is unfolding, there is considerable debate about whether Hurricane Harvey was influenced by “global warming”. While such an issue matters little to the people of Houston, it does matter for our future infrastructure planning and energy policy.
Let’s review the two basic reasons why the Houston area is experiencing what now looks like a new record amount of total rainfall, at least for a 2-3 day period over an area of tens of thousands of square miles.

Summer isn’t quite over yet, but it was another cool summer in the US with afternoon temperatures continuing a 125-year cooling trend.

Our findings indicate that the water intrusion problems in the region are due not to “sea level rise”, but primarily to land subsidence due to groundwater depletion and, to a lesser extent, subsidence from glacial isostatic adjustment. We conclude that water intrusion will thus continue even if sea levels decline. These findings are critical because the water intrusion problems in the Chesapeake Bay—and elsewhere—cannot be successfully solved unless their causes are correctly identified and appropriate remedies are devised.

Between 2007 and 2015 total annual US CO2 emissions decreased by 740 million tons (12%). An updated analysis shows that 35% of this decrease was caused by natural gas replacing coal in electricity generation, 30% by lower fuel consumption in the transportation sector, 28% by renewables replacing

There are models that predict that the interior of the East Antarctic ice sheet wouldn’t change very much, even if the West Antarctic ice sheet was taken away,” Licht said. According to these models, even if the ice sheet’s perimeter retreats, its core remains stable.

We suggest that solar activity may play a key role in driving the climatic fluctuations in North China during the last 22 centuries, with its quasi ∼100, 50, 23, or 22-year periodicity clearly identified in our climatic reconstructions.
We quantitatively illustrate that precipitation (67.4%) may have been more important than temperature (32.5%)…

La comparaison des fluctuations du CO2 atmosphérique retracées à partir de ces estimations avec des courbes des changements de température a révélé de fortes baisses du CO2 atmosphérique (200-300 ppm), couplées à de fortes hausses de la température moyenne à la surface du globe (5-8°C) à l’échelle de quelques millions d’années.
