Read here. It has become an exceedingly common tactic for global warming alarmists to claim diametrically opposed outcomes from global warming. The classic example of the C-AGW 'crook & liar' pseudo-science is that CO2-induced warming causes both cold weather and warm weather. Another example is the prediction that global warming will cause contemporaneously drought and flood conditions.
Because skeptics possess objective analysis characteristics, combined with rational common sense traits that favor actual empirical science, the predictions of simultaneous drought and flood conditions seemed to be obviously bogus scare-predictions.
And, as so commonly happens, a new peer-reviewed study determines the skeptics' hard-wired bogus B.S. detectors were correct, and the 'crooks & liars' alarmists were wrong, again.
"One of the major tenets of Climate Alarmism is that global warming will lead to the occurrence of both more floods and more droughts. Hence, it is important to check for trends in river flows that may indicate a growing propensity for such to occur; and that is what Zhang et al. did within the Susquehanna River Basin.....Based on long-term continuous daily streamflow records ending in 2006 for eight unregulated streams with record-lengths ranging from 68 to 93 years that yielded an average length of 82.5 years.....The four researchers report there was "a considerable increase in annual minimum flow for most of the examined watersheds and a noticeable increase in annual median flow for about half of the examined watersheds." However, they found that annual maximum streamflow "does not show significant long-term change.".....In the case of the Susquehanna River Basin, however, there is no support for this contention, since increases in minimum streamflow suggest a propensity for less severe and/or less frequent drought. And the fact that annual maximum streamflow shows no significant long-term change suggests there has likely been no significant long-term change at the opposite end of the spectrum, where floods might be expected."
