"...By the end of this century, global warming could make California’s San Joaquin Valley no longer suitable for stone fruit, grapes and nuts, according to researchers at the University of California-Davis and the University of Washington, Seattle."

“The main message to the industry is that we must start developing long-term strategies to deal with this quite likely problem of the future,” said Eike Luedeling, a post doctoral researcher at UC-Davis.

Most vulnerable to the warming climate, Luedeling said, is winter temperatures. To achieve proper dormancy, most tree fruit, grapes and nuts require a minimum number of chill hours — when the temperature is between freezing and 45 degrees.

According to the study, weather data from 1950 to 2000 indicates chill hours are likely to decrease by more than 50% during this century.

Penance -- Then and Now

Penance -- Then and Now
In the Middle Ages, there was no buying and selling of carbon indulgences. Now it's a booming business. "The worst of the carbon-offset programs resemble the Catholic Church's sale of indulgences back before the Reformation," said Denis Hayes, the president of the Bullitt Foundation, an environmental grant-making group. "Instead of reducing their carbon footprints, people take private jets and stretch limos, and then think they can buy an indulgence to forgive their sins." The New York Times, 4/29/07

What's a Carbon Footprint?

What's a Carbon Footprint?
A carbon footprint is a "measure of the impact human activities have on the environment in terms of the amount of green house gases produced, measured in units of carbon dioxide". It is meant to be useful for individuals and organizations to conceptualize their personal (or organizational) impact in contributing to global warming. A conceptual tool in response to carbon footprints are carbon offsets, or the mitigation of carbon emissions through the development of alternative projects such as solar or wind energy or reforestation. A carbon footprint can be seen as a subset of earlier uses of the concept of ecological footprints
