significant trends in summer flood risk in the twentieth century,” but “significant downward
trends in winter flood risk,” which latter phenomenon -- described by them as “a reduced
winter flood risk during the instrumental period” -- they specifically described as “a response to
regional warming.”
Rounding out the study of Europe, based on information on flood losses obtained from the
Emergency Events Database and the Natural Hazards Assessment Network, Barredo (2009)
developed a 1970-2006 history of normalized monetary flood losses throughout the continent -
- including the member states of the European Union along with Norway, Switzerland, Croatia
and the former Yugoslav Republic of Macedonia -- by calculating the value of losses that would
have occurred if the floods of the past had taken place under the current socio-economic
conditions of the continent, while further removing inter-country price differences by adjusting
the losses for purchasing power parities.
This work revealed, in the analyst’s words, that “there is no evidence of a clear positive trend in
normalized flood losses in Europe,” and that “changes in population, inflation and per capita
real wealth are the main factors contributing to the increase of the original raw losses.” Thus,
after removing the influence of the stated socio-economic factors, the European Commission
researcher declared “there remains no evident signal suggesting any influence of anthropogenic
climate change on the trend of flood losses in Europe during the assessed period.”
In summation, the studies described above, from locations scattered throughout all of Europe,
contradict the climate-alarmist claim that warming results in more frequent and more severe
floods. In addition, there do not appear to have been any increases in either floods or properlyadjusted
flood damages throughout all of Europe over the period of time the world’s climate
alarmists contend was the warmest of the past thousand or more years. And Europe is no
anomaly is this regard, for things have been found to be largely the same almost everywhere
such studies have been conducted; and in light of this fact -- and to not unnecessarily lengthen
our report -- in the following two paragraphs we merely cite the journal references to similar
investigations that have produced similar findings on earth’s other continents.

With respect to prior observed effects of warming on drought, we find that the peer-reviewed
scientific literature clearly demonstrates that the climate-model-based claim of more frequent
and severe droughts being induced by global warming is also false. And we begin our review of
