20180808 Since this summer was (once again) extraordinary and perhaps because of the summer recess 😉 there was a quite vital reaction of the media to our last study on sea temperature (LST) reconstructions (see e.g. the ZAMG press release). Thereby focus was mainly on the pronounced increase in LSTs since the 1980s when clean-air-acts got into effect. This caused a significant reduction of industrial aerosols (which reflect incoming solar radiation back to space) in the atmosphere. Consequently their steadily weakening cooling effect could no longer mask the warming induced by anthropogenic greenhouse gas emissions.
