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.”

THE TRUTH...

is the first thing despots go after. An unwavering commitment to it is probably what draws you to Mother Jones' journalism. And as we're seeing in the US and the world around, authoritarians seek to poison the discourse and the way we relate to each other because they can't stand people coming together around a shared sense of the truth—it's a huge threat to them.

Which is also a pretty great way to describe Mother Jones' mission: People coming together around the truth to hold power accountable.

And right now, we need to raise about $400,000 from our online readers over the next two months to hit our annual goal and make good on that mission. Read more about the information war we find ourselves in and how people-powered, independent reporting can and must rise to the challenge—and please support our team's truth-telling journalism with a donation if you can right now.
