Climatic Changes Leads To Increased Pollen Counts
- Updated: March 29, 2014
Those who are allergic to pollen have no reason to celebrate just yet, with the winter being over. By the looks of it the pollen season is likely to continue for a longer period of time. In a research, it was found that carbon dioxide plays a crucial role in the production of pollen. Researchers, isolated plants in a chamber and infused it with regulated amounts of carbon dioxide. According to the results found it was a drastic change.
Allergens tend to vary from spring to fall each year, most of the data they researched was based on ragweed as it was easier to isolate them and study the effects of regulated amounts of CO2. Researchers have found that the production of pollen has nearly doubled from the year 1999! They revealed that if the CO2 emissions continue to rise so will the count of the pollen.
A similar research mainly concentrated on Midwest and showed that pollen season was getting longer by almost 24 days from 1995 – 2011 in the Upper Midwest. There were regions like the Southern Plains that showed shortening of pollen season. However, it was found that it is not just the carbon dioxide that is causing this increase in pollen production and the lengthening of its season; it is also the rise in temperatures.
This might not be true for some parts of the country, but there are parts that will see the extended pollen season. The early warmer spring temperatures make it easier for the plants to get ahead of the game. The frost setting in later doesn’t help the case of the rise in pollen. These patterns are expected to continue through the years as the temperatures continue to soar each year. This will lead to longer pollen season and this could not be good news for more than half of the American population who have at least one allergy.
