What a misleading article. The whole point of this guy's project is to determine if there is an increased ECONOMICAL cost of weather events. He argues that the cost as a percentage of GDP has actually decreased, but in his own research admits that climate change has a significant human component and that climate change is a factor that influences trends in disasters. They also go to say that for future decades that we will experience increases in the occurrence and intensity of extreme weather events, as a result of anthropogenic climate change.
The author of this article tried to spin the research as "Climate change ain't real" BS you'd expect from Trump's mouth.
Straight from Pielke's research if you follow his link through...
"Summary Report In summer 2005 Roger Pielke, Jr. of the Center of Science and Technology Policy Research at the University of Colorado and Peter Höppe of the Geo Risks Research Department of Munich Re learned from each other that each planned to organize a workshop on the assessment of factors leading to increasing loss trends due to natural disasters. Both agreed that such a workshop was timely, especially given the apparent lack of consensus on the role of climate change in disaster loss trends. Roger Pielke, Jr. and Peter Höppe decided to have a common workshop in 2006 in Germany to bring together a diverse group of international experts in the fields of climatology and disaster research. The general questions to be answered at this workshop were: What factors account for increasing costs of weather related disasters in recent decades? What are the implications of these understandings, for both research and policy?
Consensus (unanimous) statements of the workshop participants:
1. Climate change is real, and has a significant human component related to greenhouse gases.
2. Direct economic losses of global disasters have increased in recent decades with particularly large increases since the 1980s.
3. The increases in disaster losses primarily result from weather related events, in particular storms and floods.
4. Climate change and variability are factors which influence trends in disasters.
5. Although there are peer reviewed papers indicating trends in storms and floods there is still scientific debate over the attribution to anthropogenic climate change or natural climate variability. There is also concern over geophysical data quality.
6. IPCC (2001) did not achieve detection and attribution of trends in extreme events at the global level.
7. High quality long-term disaster loss records exist, some of which are suitable for research purposes, such as to identify the effects of climate and/or climate change on the loss records.
8. Analyses of long-term records of disaster losses indicate that societal change and economic development are the principal factors responsible for the documented increasing losses to date.
9. The vulnerability of communities to natural disasters is determined by their economic development and other social characteristics.
10. There is evidence that changing patterns of extreme events are drivers for recent increases in global losses.
11. Because of issues related to data quality, the stochastic nature of extreme event impacts, length of time series, and various societal factors present in the disaster loss record, it is still not possible to determine the portion of the increase in damages that might be attributed to climate change due to GHG emissions.
12. For future decades the IPCC (2001) expects increases in the occurrence and/or intensity of some extreme events as a result of anthropogenic climate change. Such increases will further increase losses in the absence of disaster reduction measures.
13. In the near future the quantitative link (attribution) of trends in storm and flood losses to climate changes related to GHG emissions is unlikely to be answered unequivocally
