Are Extreme Weather Events From Climate Change?

Here is a link to some new work on climate change and extreme weather (flooding, etc.) detailed in Nature. The gist of the results can be gleaned from the abstracts:

Min et al

Here we show that human-induced increases in greenhouse gases have contributed to the observed intensification of heavy precipitation events found over approximately two-thirds of data-covered parts of Northern Hemisphere land areas.

From Pall et al

Here we present a multi-step, physically based 'probabilistic event attribution' framework showing that it is very likely that global anthropogenic greenhouse gas emissions substantially increased the risk of flood occurrence in England and Wales in autumn 2000.

These papers remind us that global warming is, in a sense, the wrong descriptor for what happens to a planet undergoing an enhanced greenhouse effect. It's really climate change that we should expect.
