Pakistan’s foreign minister, Makhdoom Shah Mahmood Qureshi, appealed for aid from the international community telling reporters: “Climate change, with all its severity and unpredictability, has become a reality for 170 million Pakistanis. The present situation in Pakistan reconfirms our extreme vulnerability to the adverse impacts of climate change.” The New York Times Nathanial Gronewold then added on August 20th:

Both Qureshi and U.N. Secretary-General Ban Ki-moon hinted that they would use the Pakistan crisis to spur the now-stalled international climate talks. At the very least, the disaster shows that massive funding is needed to make the developing world more resilient to extreme weather events, Ban said.

Not reported by Gronewold is that there is no evidence that climate change cause the flood in Pakistan. Furthermore, a new study by Laurens M. Bouwer, a researcher at Vrije University in Amsterdam analyzed nearly two dozen papers on natural disaster and found no link between climate change and disaster losses. The paper summarizes:

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.
