Global Warming Bad For Allergy And Asthma Sufferers

Global warming may be bad for asthma sufferers. Longer plant growing seasons are leading to weeds scattering vast amounts of pollen and conquering new territory, according to Alister Doyle, Environment Correspondent for Reuters. By spring, pollen has been in the air for months in the northern hemisphere even in countries where snows normally bring a winter respite for allergics. In southern Sweden hazel trees have been flowering since December. “In the United States the incidence of asthma is up nearly four times since 1980,” said Paul Epstein, Associate Director of the Center for Health and the Global Environment at Harvard Medical School. “No one has really been looking at the aerobiology dimension (such as pollen). But I think it helps account for it,” he said. Any further warming will make things worse.

Epstein ran a study showing that ragweed produced 60 percent more pollen when grown under twice normal concentration of carbon dioxide. At the same time, the stalks grew only 10 percent more. “Warming is touted as good for agriculture, but weeds may be reacting disproportionately fast,” he said. “This is an issue with great importance for human health and agricultural yields.”

Thank you!

We didn't know what to expect when we told you we needed to raise $400,000 before our fiscal year closed on June 30, and we're thrilled to report that our incredible community of readers contributed some $415,000 to help us keep charging as hard as we can during this crazy year.

You just sent an incredible message: that quality journalism doesn't have to answer to advertisers, billionaires, or hedge funds; that newsrooms can eke out an existence thanks primarily to the generosity of its readers. That's so powerful. Especially during what's been called a "media extinction event" when those looking to make a profit from the news pull back, the Mother Jones community steps in.

The months and years ahead won't be easy. Far from it. But there's no one we'd rather face the big challenges with than you, our committed and passionate readers, and our team of fearless reporters who show up every day.
