New York and other areas in the northeastern U.S. are currently experiencing high levels of pollen due to the late spring causing different pollination cycles to overlap. The northeast U.S. is currently experiencing what many are calling a “pollen tsunami.” The unusually intense amount of pollen in the air has been attributed to the delay in spring due to prolonged cold weather. As a result, the early cycle for certain tree pollen has been delayed and is now coinciding with the regular cycle and the onset of grass pollination. On top of that, precipitation during the long winter hydrated tree roots more, which is resulting in a strong, intense release. Despite complaints from allergy sufferers, the levels are not high enough to break any records. Experts recommend that people who are sensitive stay indoors and wash hands and clothes that may have residue on them. Pollen is generally visible as a fine green and yellow dust that tends to coat cars and other outdoors items. It is released by trees and plants to fertilize others of the same species. Pollen levels are predicted to rise by 20 percent in the next five years due, at least in part, to climate change.
