Briefly wondering why this has never been an issue for me till I realised that it doesn't affect those of us who will only be running one project at a time.

"[Dr Dim] Coumou, [at the Potsdam Institute for Climate Impact Research] acknowledges his study shows a correlation � not causation � between more frequent summer blocking patterns and Arctic warming. �To show causality, computer modelling studies are needed, but it is questionable how well current climate models can capture these effects,� he said."

"Prof Tim Palmer, at the University of Oxford, wrote in a PNAS article in 2013 that understanding changes to blocking patterns may well be the key to understanding changes in extreme weather, and therefore to understanding the worst impacts of climate change on society. But he said climate models might have to run down to scales of 1km to do so. �Currently, national climate institutes do not have the high-performance computing capability to simulate climate with 20km resolution, let alone 1km,�"
