The sun was completely free of spots on 11 days in July. Notable: while during last month the sun’s northern hemisphere was more active (in June all sunspots were in the northern hemisphere), last month the southern hemisphere was the most active part with 60% of the sunspots appearing there. The following diagram shows the course of solar cycle 24 thus far (…)

The now three-year-old Plate Climatology Theory is on the brink of total confirmation. This is the result of two just-released and very telling Antarctic research studies. Combining the results of these two studies with the massive amounts of pre-existing data it is possible to show with very high certainty that melting of West Antarctic glaciers is directly related to bedrock heat flow and chemically charged heated fluid flow from the 5,000-mile-long West Antarctic Rift System (see Figure 1).

Earlier this year, DEFRA published a report by the Air Quality Expert Group into the impacts of biomass on air quality. The results make for startling reading.
Among the findings are: (…) (…)

Researchers have used computer simulations to analyse how plate tectonics have evolved on Earth over the last three billion years. They show that tectonic processes have changed in the course of the time, and demonstrate how those changes contributed to the formation and destruction of continents. The model reconstructs how present-day continents, oceans and the atmosphere may have evolved.

Our results show up to 1°C of warming. The average divergence between the proxy temperature record and our ANN projection is just 0.09 degree Celsius. This suggests that even if there had been no industrial revolution and burning of fossil fuels, there would have still been warming through the twentieth century – to at least 1980, and of almost 1°C.

AFTER deconstructing 2,000-year old proxy-temperature series back to their most basic components, and then rebuilding them using the latest big data techniques, John Abbot and I show what global temperatures might have done in the absence of an industrial revolution. The results from this novel technique, just published in GeoResJ, accord with climate sensitivity estimates from experimental spectroscopy but are at odds with output from General Circulation Models.

Tremendous amounts of soot, lofted into the air from global wildfires following a massive asteroid strike 66 million years ago, would have plunged Earth into darkness for nearly two years, new research finds. This would have shut down photosynthesis, drastically cooled the planet, and contributed to the mass extinction that marked the end of the age of dinosaurs.

The Middle Eastern countries that are looking at coal are trying to diversify their fuel mix, and to reduce vulnerability to economic or supply shocks. Gas is cheap at the moment but its price is volatile, and states such as Dubai, Egypt and Turkey do not want to be too import-dependent. For Dubai, which attracted a very competitive bid from Acwa and Harbin, coal is a key part of strengthening its negotiating position with other suppliers. Iran and Turkey are trying to maximise the use of their domestic coal, and for Turkey, reliance on rivals Iran and Russia for two-thirds of its gas is dangerous.
Despite gas prices being low at the moment, coal is cheaper still — at least once the required import facilities are constructed. Chinese power and engineering companies, looking for other markets, are offering their expertise and low-cost financing.

Total rachète le Danois Maersk Oil pour plus de 7 milliards de dollars, soit sa plus grosse acquisition depuis celle d’Elf Aquitaine en 2000. Grâce à elle, le pétrolier vise 3 millions de barils-jours en 2019.

That’s the peak oil argument in a nutshell, but the peak demand argument is entirely different. In this case, oil production falls — not because of geological factors — but because the world turns its back on oil as cleaner, cheaper options become available. Electric vehicles and ride-sharing on a massive scale are envisioned as two of the key factors that will make oil obsolete.

In order to determine if records are possible in 2017, one must know the previous records as well as the average to date and what is required for the rest of the year in order for a particular data set to set a new record.
For the five data sets I cover, records were set in 2016. For now, I am not concerned about the statistical significance of the records, nor the number of decimal places. I merely want to know if the record can be beaten this year. At the end of the year, I plan on reporting any records and how statistically significant they are.

Al Gore has provided a target-rich environment of deceptions in his new movie.
After viewing Gore’s most recent movie, An Inconvenient Sequel: Truth to Power, and after reading the book version of the movie, I was more than a little astounded. The new movie and book are chock-full of bad science, bad policy, and factual errors.
