A new paper by Otto et al in Nature Geoscience has made an updated estimate of the transient climate response (TCR) implied by the climate change we have observed from 1970 to 2009. It finds the TCR to lie in the range 0.7–2.5 °C, with a best estimate of 1.4 °C. This is somewhat lower than… Continue Reading and comment

This recent paper in the journal Current Biology claims that the digestive tracts of dinosaurs emitted 520 Mtonnes of methane a year, comparable to the total modern-day methane emissions. The authors suggested that this could have been an important factor in warm Mesozoic climates. Unfortunately, they… Continue Reading and comment
