Climate, Weather, Pollen, and Health

1 Determine the climate factors that influence the timing and severity of the allergenic pollen season at a national scale 2 Identify the weather patterns during the pollen season that are related to high pollen count days 3 Determine links between pollen season parameters (e g onset, peak, duration) and health outcomes



Anthropogenic climate change is worsening North American

Dec 18, 2020 · pogenic climate change may increase pollen concentrations and extend pollen seasons While greenhouse and field studies indi-cate that pollen concentrations are correlated with temperature, a formal detection and attribution of the role of anthropogenic climate change in continental pollen seasons is urgently needed



Pollen-based continental climate reconstructions at 6 and 21

climate The observed response in pollen assemblages is due in part to quantitative compositional shifts, and in part to range boundary shifts When climate change is rapid, so is compositional change The composition of pollen assemblages tracks the climate with lags of the order of 100 years or less (Gajewski 1987; Prentice et al 1991;



Pollen Evidence of a Humid Mid-Holocene Climate from Bahar

pollen is over-represented in the pollen spectra, confirming the widelyreported - over-representation of Pinus pollen in the semi-arid and arid regions of China and Mongolia [18] Despite the dominance of grasses in the steppes and desert steppes in the Or-dos Plateau, Gramineae pollen percentages are rather low, being below 10 in

Extreme Allergies and Global Warming

increase in ragweed pollen production 17 Climate change impacts on ragweed are amplified in urban areas Buildings, roads, and other infrastructure can make cities several degrees warmer than surrounding rural areas, creating what are known as urban heat islands At the same time, the large number of polluting vehicles, power plants, and



POLLEN ALLERGIES - World Allergy Organization

Pollen allergy is an allergic condition affecting the mucous membranes of the nose and the eyes etc , usually characterized by nasal discharge, nasal congestion, and itchy and watery eyes, itchy nose, inner ears and roof of the mouth, that are caused by a hypersensitivity to airborne pollen, such as the pollen of trees, grasses, and weeds
