"I don't think the American public has gripped in its gut what could happen," he said. "We're looking at a scenario where there's no more agriculture in California." And, he added, "I don't actually see how they can keep their cities going" either....

Chu warned of water shortages plaguing the West and Upper Midwest and particularly dire consequences for California, his home state, the nation's leading agricultural producer.

In a worst case, Chu said, up to 90% of the Sierra snowpack could disappear, all but eliminating a natural storage system for water vital to agriculture.

The oceanside enclave in Marin County has enacted some of the state's toughest water restrictions. Each customer - with the exception of schools and some businesses - may use no more than 150 gallons a day, about 4,500 gallons each month.

A third violation of the order would allow the Bolinas Community Public Utility District to cut off water.

Without drastic cutbacks, officials say, the community of 1,200 could run out of water by the end of April. The town on the southern end of the Point Reyes Peninsula already is drawing from two emergency reservoirs, one of which is effectively empty.

He said the threat of warming is keeping policymakers focused on alternatives to fossil fuel, even though gasoline prices have fallen over the last six months from historic highs. But he said public awareness needs to catch up. He compared the situation to a family buying an old house and being told by an inspector that it must pay a hefty sum to rewire it or risk an electrical fire that could burn everything down.

"I'm hoping that the American people will wake up," Chu said, and pay the cost of rewiring.

Democrats have decided to allow a quarter-century ban on drilling for oil off the Atlantic and Pacific coasts to expire next week, conceding defeat in a months-long battle with the White House and Republicans set off by $4 a gallon gasoline prices this summer.

House Appropriations Committee Chairman David Obey, D-Wis., told reporters Tuesday that a provision continuing the moratorium will be dropped this year from a stopgap spending bill to keep the government running after Congress recesses for the election.

Republicans have made lifting the ban a key campaign issue after gasoline prices spiked this summer and public opinion turned in favor of more drilling. President Bush lifted an executive ban on offshore drilling in July.

"If true, this capitulation by Democrats following months of Republican pressure is a big victory for Americans struggling with record gasoline prices," said House GOP leader John Boehner of Ohio. (AP via SFGate)

I think it's awful. This battle is not over. We will come back and fight another day - that's for sure.

I regret the House appropriations committee didn't see fit to go with a better, more widely accepted alternative, which would have kept in place a moratorium 50 miles or more off shore. In my view, there were better options than this.
