We describe late Miocene tetrapod footprints (tracks) from the Trachilos locality in western Crete (Greece), which show hominin-like characteristics. They occur in an emergent horizon within an otherwise marginal marine succession of Messinian age (latest Miocene), dated to approximately 5.7 Ma (million years), just prior to the Messinian Salinity Crisis.
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.
Various sources, scientists publishing their opinion in the media, claim that Tropical Storm Harvey, recently landed in Texas, is one more signal of the influence of global warming on such catastrophic events. These claims are based on model calculations. Let’s examine the facts.
This report introduces CDP’s League Table for oil and gas companies, highlighting company performance across a range of portfolio, emissions and water-related metrics which indicate carbon risk preparedness and highlights earnings risks for oil and gas companies.
Highest ranked companies are Statoil, Eni and Total.
Lowest ranked companies are Suncor, ExxonMobil and Chevron.
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.
