Global Warming Is Likely to Have Much Larger Effects on Some

Global warming is likely to have much larger effects on some locations than others. Why are planners particularly concerned about California?

A) Grapes require cool spring weather; warming could impact the California grape harvest and plunge the state into an economic recession.
B) Warmer temperatures mean more ocean evaporation and cloud cover reducing the sunlight needed to drive the massive agricultural industry in California.
C) Warmer temperatures mean more ocean evaporation and rainfall; as this runoff reaches the coast it will reduce ocean salinities and impact coastal life.
D) The precipitation falling on the Sierra Nevada could be rain rather than snow; melting snow gradually releases critically needed water during the spring and summer.
