Meteorologists vs. Climatologists: the final confrontation...

Basically, we're back to the same old opposition: people with more education being regarded as having a private agenda by people with less education. We're doomed by our own petty behaviour.

The split between climate scientists and meteorologists is gaining attention in political and academic circles because polls show that public skepticism about global warming is increasing, and weather forecasters — especially those on television — dominate communications channels to the public. A study released this year by researchers at Yale and George Mason found that 56 percent of Americans trusted weathercasters to tell them about global warming far more than they trusted other news media or public figures like former Vice President Al Gore or Sarah Palin, the former vice-presidential candidate.

Yet, climate scientists use very different scientific methods from the meteorologists. Heidi Cullen, a climatologist who straddled the two worlds when she worked at the Weather Channel, noted that meteorologists used models that were intensely sensitive to small changes in the atmosphere but had little accuracy more than seven days out. Dr. Cullen said meteorologists are often dubious about the work of climate scientists, who use complex models to estimate the effects of climate trends decades in the future.

But the cynicism, said Dr. Cullen, who now works for Climate Central, a nonprofit group that works to bring the science of climate change to the public, is in her opinion unwarranted.

“They are not trying to predict the weather for 2050, just generally say that it will be hotter,” Dr. Cullen said of climatologists. “And just like I can predict August will be warmer than January, I can predict that.”

Three years ago, Dr. Cullen found herself in a dispute with meteorologists after she posted a note on the Weather Channel’s Web site suggesting that meteorologists should perhaps not receive certification from the meteorological society if they “can’t speak to the fundamental science of climate change.”

Resentment may also play a role in the divide. Climatologists are almost always affiliated with universities or research institutions where a doctoral degree is required. Most meteorologists, however, can get jobs as weather forecasters with a college degree. 

“There is a little bit of elitist-versus-populist tensions,” Mr. Henson said. “There are meteorologists who feel, ‘Just because I have a bachelor’s degree doesn’t mean I don’t know what’s going on.’ ”

Whatever the reasons, meteorologists are far more likely to question the underlying science of climate change. A study published in the January 2009 newsletter of the American Geophysical Union, the professional association of earth scientists, found that while nearly 90 percent of some 3,000 climatologists who responded agreed that there was evidence of human-driven climate change, 80 percent of all earth scientists and 64 percent of meteorologists agreed with the statement. Only economic geologists who specialized in industrial uses of materials like oil and coal were more skeptical.
