Triple-digit heat, record ocean warmth grip region Play

If you go anywhere more than 5 miles from the ocean this week, expect temperatures of 100 to 110 degrees daytimes. That's the forecast from the National Weather Service.

The Malibu mountains will hit 102 degrees Monday, 106 Tuesday, 108 Wednesday.

Off the coast, the earth's oceans broke a heat record on Friday. The oceans were warmer than any day in recorded history Friday, due to a combination of long-term human-caused global warming and short-term effects of El Niño.

And the warnings are everywhere: sea level rise spurred by climate change will almost certainly menace Malibu with record coastal flooding this fall and winter.

This week we are going to see highs of 108 degrees in Agoura Hills. That's the weather forecast. The climate forecast is even worse.

Last week, the high tides that rolled in the Santa Monica Bay were 5 inches above the predicted tides in the tide tables.

The L.A. Times reports that the tides were coming in about 6 inches higher than the official forecast in San Diego, the Port of Los Angeles and Santa Barbara. Near Eureka, tides were 9 inches higher than forecast.

Meteorologists are warning this is bad and going to get worse this fall and winter as a record-breaking El Niño is brewing. Water levels are already between 6 to 12 inches above average up the west coast of Mexico.

We've seen this before. During the "very strong" El Niños of 1983 and 1998, we saw record high tides in Malibu. Houses in eastern Malibu in some cases collapsed. Along PCH, homes fell into the ocean.

University of California meteorologist Daniel Swain:

"This year's event will not only be very strong, equivalent to the colloquially super El Niño, but we're going to go well beyond that territory. I will suggest we need a new category of Extreme El Niño."

His recommendation on what to do right now: buy flood insurance. And he's not kidding. It takes about a month for federal flood insurance to take effect.

"There is a cap around a quarter million dollars, which in California does not necessarily mean you can rebuild your house, although usually in floods you don't have the whole houses destroyed in most cases," Swain said. "Supplemental private flood insurance exists, but I would strongly suggest folks at least consider the baseline of exposure. I'm certainly advising all my family and friends who live in even hypothetically flood-prone areas to take a serious look at insurance this year."
