A heatwave struck large parts of Europe during the last week of June 2019, breaking several historical records at single locations in France, Switzerland, Austria, Germany, the Czech Republic and Spain. Here we present an analysis of the role of human activities in the heatwave, conducted in near real time by using well assessed methodologies. The analysis is not yet peer-reviewed and was written quickly, albeit by scientists experienced in event attribution, working with More »

It is generally considered that the perennial glaciation of Greenland lasting several orbital cycles began around 2.7 Ma along with the intensification of Northern Hemisphere glaciation (NHG). Both data and model studies have demonstrated that a decline in atmospheric pCO2 was instrumental in establishing a perennial Greenland ice sheet (GrIS), yet models have enerally used simplistic pCO2 constraints rather than data-inferred pCO2 evolution. Here, using a method designed for the long-term More »
