...higher CO2 concentrations lead to vast increases in ragweed pollen production. "There's no denying there's a change," says Paul Ratner, an immunologist with the American College of Allergies. "It's definitely bad news for people who have allergies." (Hear Ratner talk about the connection between warming and asthma on this week's Greencast...

The World Health Organization estimates that 300 million people globally have asthma, with 250,000 dying from the disease each year. That rate is up considerably over the past few decades, and scientists say a number of factors could be at work. One clear reason is rising levels of ragweed pollen - which can be connected directly to rising levels of CO2. Researchers have shown repeatedly that elevated levels of CO2 stimulate weeds to produce pollen out of proportion with their growth rates - meaning...
...make things worse. So, what can be done to help millions of sneezing, watery-eyed patients? As allergy sufferers already know, not a whole lot. But any action taken to control rising CO2 levels might at least help stem the increase in global allergy rates. So far, the global asthma epidemic shows no signs of abating, and in a warmer world, effective treatments for allergies will likely become even more important. One option for allergy suffers might be to start agitating for action to reduce CO2 emissions - after all, the only thing you have to lose is your breath...
