Climate change is making life tougher for those with allergies, but it’s possible to be allergy-free. A European study published online concluded that allergic reactions to ragweed (the most common cause of what is known as “hay fever”) are in fact getting worse; people who are already sensitive to ragweed are becoming more sensitive, and more and more people who never had problems before are becoming allergic. In fact, in 25-40 years, these researchers estimate the population of Europeans sensitive to ragweed will double, from 33 million to 77 million. Although this study was done in Europe, similar factors, associated with climate change, are at work here in the US. As explained by Lewis Ziska, a plant physiologist at the US Department of Agriculture, warmer temperatures and higher levels of carbon dioxide have encouraged ragweed growth, producing a larger plant and about ten times more ragweed pollen. In addition, it appears that this pollen is a more potent allergen.The Europea…
