Have Disaster Losses Increased Due to Anthropogenic Climate Change?
New peer reviewed paper:
Bouwer, L.M. (in press). Have disaster losses increased due to anthropogenic climate change? Bulletin of the American Meteorological Society, doi:10.1175/2010BAMS3092.1
Abstract
The increasing impact of natural disasters over recent decades has been well documented, especially the direct economic losses and losses that were insured. Claims are made by some that climate change has caused more losses, but others assert that increasing exposure due to population and economic growth has been a much more important driver. Ambiguity exists today, as the causal link between climate change and disaster losses has not been addressed in a systematic manner by major scientific assessments. Here I present a review and analysis of recent quantitative studies on past increases in weather disaster losses and the role of anthropogenic climate change. Analyses show that although economic losses from weather related hazards have increased, anthropogenic climate change so far did not have a significant impact on losses from natural disasters. The observed loss increase is caused primarily by increasing exposure and value of capital at risk. This finding is of direct importance for studies on impacts from extreme weather and for disaster policy. Studies that project future losses may give a better indication of the potential impact of climate change on disaster losses and needs for adaptation, than the analysis of historical losses.
Capsule summary
Climate change is often seen as the culprit of increasing economic losses from weather disasters. The scientific literature however shows that there are other causes up to now.

as per the general accessibility i could go through just the highlighted part and feel alike. researches proved that after 100 or million years temperature rises naturally. glacial and inter-glacial stages come by turns. the concern of climate changes may help human being just to prolonged the natural process few periods forward.
