    And the study does not include the events of 2010, and this January.

    Human contribution to more-intense precipitation extremes : Nature : Nature Publishing Group

    Extremes of weather and climate can have devastating effects on human society and the environment1, 2. Understanding past changes in the characteristics of such events, including recent increases in the intensity of heavy precipitation events over a large part of the Northern Hemisphere land area3, 4, 5, is critical for reliable projections of future changes. Given that atmospheric water-holding capacity is expected to increase roughly exponentially with temperature—and that atmospheric water content is increasing in accord with this theoretical expectation6, 7, 8, 9, 10, 11—it has been suggested that human-influenced global warming may be partly responsible for increases in heavy precipitation3, 5, 7. Because of the limited availability of daily observations, however, most previous studies have examined only the potential detectability of changes in extreme precipitation through model–model comparisons12, 13, 14, 15. 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. These results are based on a comparison of observed and multi-model simulated changes in extreme precipitation over the latter half of the twentieth century analysed with an optimal fingerprinting technique. Changes in extreme precipitation projected by models, and thus the impacts of future changes in extreme precipitation, may be underestimated because models seem to underestimate the observed increase in heavy precipitation with warming16.

    This past years we have seen a number of weather events cause large losses of life. We must do something before everything is too late..

    Old Crock, list the full article, I followed your link and here it is. How in the hell can you have a discussion about an article we have to buy. How about posting the actual report instead of the press reslease of an article about a study.

    Now that is Science, right, basing your opinion on a headline, not the science.

    Scientific journals are expensive to produce and publish. However the abstract contains the conclusions. And one can always go to a public library if you really want to know more. You do know what one of those is?

    While the amplitude of many of those swings is debatable, both ways, the forcings that produced them were far less than the present forcings from the GHGs that we have added to the atmosphere.
