Because these moderate extremes are by definition more common, and because the authors looked at global statistics rather than those for highly localized, rare events, the conclusions are extremely robust, said Peter Stott, leader of the Climate Monitoring and Attribution Team at the Met Office Hadley Centre, in the U.K. «I think this paper is very convincing,» said Stott, who was not involved in the research.

This coupled with the fact that such events are not selective and often hit those countries that are least well equipped to deal with their impacts and set these countries back years in terms of development has been the motivation behind a new partnership between the World Weather Attribution (WWA) Initiative and the Climate & Development Knowledge Network (CDKN).

A new analysis published in the journal Environmental Research Letters establishes that seasonal forecast sea surface temperature (SSTs) can be used to perform probabilistic extreme - event attribution, thereby accelerating the time it takes climate scientists to understand and quantify the role of global warming in certain classes of extreme weather events.

Now, this field of «extreme event attribution» may be poised to make its debut in court.

This is addressed by evaluating change in global or large - scale patterns in the frequency or intensity of extremes (e.g., observed widespread intensification of precipitation extremes attributed to human influence, increase in frequency and intensity of hot extremes) and by event attribution methods.

Burger isn't sure whether extreme event attribution science is strong enough yet to stand up in court, but his team is in the middle of an in - depth analysis to answer just that question.

These events would thus be good candidates for attribution studies — as Bob Henson of UCAR remarked in connection with the colorado event:

The Arab Spring surprised many people, including some who had expertise, and while attribution of such an event to a particular cause is probably impossible, there are people (as written up in The Economist, for example) who link at least some of the causation to food prices, and there in turn people who link at least some of the food - price swings to climate change.
