Plain speaking from an expert

To a layperson, the world of climatology can be an intimidatingly foreign land. Denizens of this world -- scientists -- speak a daunting, often-impenetrable blend of acronyms (AGW, IPCC, WPAC, ENSO), Latinisms (anomalies, coterminous, precipitation deficits), and math (confidence limits, regression-based, boundary knots).

Besides the sheer complexity of global climate systems, the dreariness of this jargon may be one of the big reasons the general public has been slow to awaken to the seriousness of the threat of global warming. In fact, a conference on climate change organized by Yale last year called for "training scientists to speak in language that is understandable to different audiences."

One scientist who needs no such training is Bill Patzert, an oceanographer and meteorologist at the Jet Propulsion Laboratory in Pasadena, Calif., an institution closely linked to NASA. In the world of science, Patzert is known for his work matching TOPEX satellite weather data to the actual behavior of the Pacific Ocean and its weather systems, especially El Nino and its less-well-known counterpart La Nina. In the media world, he is a go-to guy for comments on weather patterns for the L.A. Times, the San Diego Union-Tribune, and CBS News, in part because he has a sense of humor.

Patzert, who has briskly guided my reporting on climate questions for years, generously agreed to an extended email interview for Grist. Since he has become known for his work with the media, and even won medals for his outreach efforts, I thought I'd begin with a question about why the rhetoric of climatology is so turgid and difficult. His answer was more than I bargained for:

Wildfires are now in season

Ah, the oncoming of fall in Southern California.

Flakes of ash fall thick, soft, and white as snow. Clouds of smoke bigger than mountains fill the sky. Orange-y sunlight and hazy gray skies last for weeks on end. Thousands of firefighters struggle to contain blazes with flames 20 and 30 feet high. Bulldozers cut firelines. Planes and helicopters water-bomb all through the day. Evacuation orders typically arrive in the dead of night, when the skies are glowing and the traffic is wild.

You are now entering science fiction land …

Sometimes life in the 21st century feels like a weird science fiction movie -- one so unnerving it's difficult to distinguish reality from nightmare.

Here are some science fiction-y nightmares well-known scientists, writers, and bloggers brought forward this week:

A Q&A

The best guide I know to the climatological consensus is soft-spoken Kelly Redmond, who helps lead the influential and wide-ranging Western Regional Climate Center. The WRCC has done a great deal of work for the US Global Change Research Program on climate change issues, such as investigating the possibility that global warming could seriously degrade the Sierra snow pack on which much of California depends for water.

But don't let all that brainpower discourage you! Although a scientist, Redmond mostly speaks in commonsense English, has a bit of the poet in him, and has long worked to help ordinary folks (and reporters) understand climate issues.

For a story on fire in Southern California, I emailed some questions to Redmond. His answers were so helpful and illuminating, I expanded the interview to a wider discussion of how climate in the Western U.S. is changing.
