Climate Change Scenarios for California, USA – May 23rd, 201337.7N 122.4W
This image focuses on the San Francisco Bay region of the US state of California. Climate model simulations used to investigate possible changes in regional climate over California have predicted that by the end of the twenty-first century, temperatures in the state will increase by 2°C to 6°C (about 3.5 °F to 11°F). While there is greater warming in summer than in winter, all simulations indicate that hot daytime and nighttime temperatures (heat waves) will increase in frequency, magnitude, and duration.
Projected precipitation is marked by considerable variability: in the southern half of California, the models show a decline in annual precipitation. Sea level rise predictions range from 77 cm to 140 cm (30 to 55 in) over historical levels by 2100. The rise of mean sea level would provoke an increase in extreme events, as gaged by exceedances above a relatively high or rare historical threshold. Such events are becoming much more frequent and have longer durations than has been seen historically (click here for more information).
