«Unabated climate change will probably further weaken summer circulation patterns which could thus aggravate the risk of heat waves,» says co-author Jascha Lehmann «Remarkably, climate simulations for the next decades, the CMIP5, show the same link that we found in observations. (sciencedaily.com)
A parallel study has tentatively documented a general slowdown of atmospheric summer circulation in the mid-latitudes. (climatesignals.org)
«I think the minimum this year is more remarkable than in 2007,» said NSIDC scientist Julienne Stroeve in an email, «since the 2007 minimum was in large part driven by [unusual weather patterns], and this summer we shattered the 2007 minimum under more normal summer circulation patterns.» (climatecentral.org)
