Evidence suggests that the year-class strength of salmon populations is related to decadal scale climatic/ocean fluctuations. The interactions have complex latitudinal patterns and appear to involve the major food web and current structures of the North Pacific. To understand the effect of climate on Columbia River salmon the North Pacific system must be considered. A brief review of the patter...
Perhaps the most fundamental insight from fishery science is that ecosystems impose important and predictable constraints on food production from the sea. The familiar hump-shaped growth curve implies that the growth rate and carrying capacity of a species limit its production: Once stocks are depleted, further increasing fishing pressure will only lead to decreases in catch. This logic underpi...

We investigate whether stock markets efficiently price risks brought on or exacerbated by climate change. We focus on drought, the most damaging natural disaster for crops and food-company cash flows. We show that prolonged drought in a country, measured by the Palmer Drought Severity Index (PDSI) from climate studies, forecasts both poor stock returns and profitability ratios for food companie...

This paper applie...
