1 Global Warming, Global Warming Policy and Mortality Rates : Indur M. Goklany Independent Scholar Fourth International Climate Change Conference Chicago, IL May 16–18, 2010

2 Organization of Talk Empirical data – Excess winter deaths – Extreme events – Malaria – Hunger, cereal yields, cereal production – Life expectancy Ranking GW among other global health risks Potential death & disease in developing countries from biofuel production 2

10 Reasons for the increase of hunger according to FAO, State of Food Insecurity 2009 The food price crisis The global economic slowdown Insufficient investment in agriculture The increase is not a result of poor crop harvest Source: policybriefs/multimedia0/presentation-the-state-of-food- insecurity/en/ 10

17 Death & Disease in Developing Countries per Million People in Extreme Poverty Poverty Headcount (millions) ThresholdCommentSource OldChen & Ravallion (2007) ,454*New* New = 1.5 x OldChen & Ravallion (2008) In 2004 due to 6 diseases of poverty, according to WHO (2009) Death & disease rate per million living in extreme poverty 7.7 million deaths5,270 deaths per million 267 million lost DALYs183,000 lost DALYs per million 17

18 Death & Disease in Developing Countries in 2010 Due to Biofuel Production Poverty Headcount (millions) CommentSource 20051,374 Differences due to country coverage WB Global Economic Prospects (2009) 20051,208 De Hoyos & Medvedev (2009) No biofuel production, Drop due to economic growth D&M (2009) Increase due to biofuel production D&M (2009) Increase in Deaths = 192,000 Increase in Burden of Disease = 6.7 million 18

20 Findings  In developed world, more people die in winter, but trend is downward due to greater wealth and fuel affordability  Deaths and death rates from extreme weather events, malaria, hunger, and other climate sensitive health risks have declined over the long term  Mortality Rates Life Expectancies  GW ranks below the top 20 global health problems today, and will advance only if these other risks are solved first  Death and disease from biofuel production more likely to be real than those estimated due to GW  Increased death and disease from biofuel production most likely exceeds any reductions from reduced GW 20

21 Conclusions  GW or its underlying human causes (if any) have not increased death and disease in the aggregate.  In fact, they are probably responsible for the worldwide decreases in mortality rates and increase in life expectancy over the last century.  GW policies may already have killed more than they have saved  And may kill even more if they reduce energy use prematurely and/or economic development, particularly for the less well-off 21
