Global warming has many consequences but a study recently reveals the link between rising temperatures and an impact on plants. The whole of the plant endures stress due to high temperatures but pollen in particular, has shown to be the most sensitive aspect. Seasonal changes have altered during the last 30 years where pollen begins approximately 3 weeks earlier and lasts an additional 10 days following the usual close to the season. Increased pollen potency of up to 21% is a concern.
As the climate emergency escalates so will the levels of pollen increase. This will have a detrimental impact on the suffering of those with hay fever but it also creates an additional problem in that the internal timings of plants will be affected. This extension of the pollen season is an unpleasant by-product of the climate emergency and is another reason why we must halt global warming.
