Climate Bipolar Disorder Strikes Again

When warm El Nino dominated, Trenberth blamed it on global warming.

One respected climate scientist who has gone out on a limb about the global warming-El Niño connection is Kevin Trenberth, a climatologist at the National Center for Atmospheric Research in Boulder, Colorado. He thinks that El Niño may function as a kind of pressure release valve on the tropics. In an era of global warming, Trenberth says, ocean currents and weather systems might not be able to bleed off all the heat pumped into the tropical seas. Periodically, it has to get rid of the excess that builds up, he suggests, and that safety valve is El Niño.

Since 1976, there have been seven El Niños. Based on the most reliable records, which go back 120 years, we would have expected to see only five, Trenberth says. Could the recent upturn be part of a natural cycle or some kind of oddball blip on the climate radar screen?

Now that cool La Nina is dominating, they are trying to blame that on global warming.

This is mainly the fault of La Niña, a cyclical weather system. “It used to occur once every five to six years, but it is increasingly frequent and severe due to global warming,” says Lozano. The current spell of bad weather is expected to last another two months.

Whatever the weather is, they will rationalize it as being caused by global warming. The incredibly low (non-existent) standards of climate science make this possible.
