ABSTRACT: We investigate the effect of climate change on population growth in 18th and 19th century Iceland. We find that annual temperature changes help determine the population growth rate in pre-industrial Iceland: a year 1 ◦ C cooler than average drives down population growth rates by 0.57 % in each of the next two years, for a total effect of 1.14%. We also find that 18th and 19th century Icelanders adapt to prolonged changes in climate: these adaptations take about 20 years and reduce the short run effect of annual change in temperature by about 60%. Finally, we find that a 1 ◦ C sustained decrease in temperature decreases the steady state population by 10 % to 26%.
