Records are falling all around in California.

A heat wave has been setting record temperatures. And then on Monday, California set a record for all-time peak electricity usage. From the NYT:

Gov. Arnold Schwarzenegger ordered state agencies to reduce electricity consumption by 25 percent, acting on a prediction from the state’s power grid managers that demand would peak at 52,000 megawatts, a mark they had not expected to reach until 2011. Demand peaked at 50,270 megawatts at 2:44 p.m. Pacific time, breaking the record of 49,036 megawatts set last Friday.

More heat = more electricity usage.
More electricity usage = more carbon emissions.
More carbon emissions = … you get the idea.
