Cleaving The TV "Meteorologists" From The Real Meteorologists

Jerry asks:
Remember the "Weather Wrangler" and "Alfo"? Would you have wanted their opinions about ANYTHING?
This story makes me so sad. It just shows that even many college-educated people just have no grasp, after all that investment of time and money, of scientific truth. Ideology works like some kind of thought-stunting hormone!

To be clear, climatologists have usually worked in their fields far longer, and are required to demonstrate a higher degree of education, than TV weather presenters have done, or, for that matter, many other meteorologists. That's not a slam against meteorologists (of whom I'm one) - it's just a fact.

Listen, Mr. Populist Meteorologist, take it from a Ph.D.-level meteorologist (myself), just because you have a bachelor’s degree DOES mean you don’t know what’s going on!:
The debate over global warming has created predictable adversaries, pitting environmentalists against industry and coal-state Democrats against coastal liberals.

But it has also created tensions between two groups that might be expected to agree on the issue: climate scientists and meteorologists, especially those who serve as television weather forecasters.

Climatologists, who study weather patterns over time, almost universally endorse the view that the earth is warming and that humans have contributed to climate change. There is less of a consensus among meteorologists, who predict short-term weather patterns.

...Such skepticism appears to be widespread among TV forecasters, about half of whom have a degree in meteorology. A study released on Monday by researchers at George Mason University and the University of Texas at Austin found that only about half of the 571 television weathercasters surveyed believed that global warming was occurring and fewer than a third believed that climate change was “caused mostly by human activities.”

More than a quarter of the weathercasters in the survey agreed with the statement “Global warming is a scam,” the researchers found.

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.

...“In a sense the question is who owns the atmosphere: the people who predict it every day or the people who predict it for the next 50 years?” said Bob Henson, a science writer for the University Corporation for Atmospheric Research, who trained as a meteorologist and has followed the divide between the two groups.

Mr. Henson added, “And the level of tension has really spiked in recent months.”

The reasons behind the divergence in views are complex. The American Meteorological Society, which confers its coveted seal of approval on qualified weather forecasters, has affirmed the conclusion of the United Nations’ climate panel that warming is occurring and that human activities are very likely the cause. In a statement sent to Congress in 2009, the meteorological society warned that the buildup of heat-trapping gases like carbon dioxide in the atmosphere would lead to “major negative consequences.”

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.’ ”
