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: (…) (…)

Earth history: How continents were recycled
by Ruhr-Universitaet-Bochum, August 22, 2017 in ScienceDaily
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.
Big data finds the Medieval Warm Period – no denial here
by Jennifer Marohasy, August 22, 2017
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.

Most of the Recent Warming Could be Natural
by Jennifer Marohasy, August 21, 2017
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.
