According to a new study published in the journal Nature, the US is going to face up to a 200% increase in pollen by the end of this century. The projection is based on a model that takes into account the change in pollen with respect to variations in global temperature.
The pollen season will start earlier and end later than their normal cycle, on one hand, it’ll extend the flowering season but on the other hand, it’ll decrease the maximum pollen concentration, flattening the curve and extending it.
How much pollen is produced depends on how the plant grows. Rising global temperatures will boost plant growth in many areas, and that, in turn, will affect pollen production. But temperature is only part of the equation. It was found that the bigger driver of the future pollen increase will be rising carbon dioxide emissions.
The higher temperature will extend the growing season, giving plants more time to emit pollen and reproduce. Carbon dioxide, meanwhile, fuels photosynthesis, so plants may grow larger and produce more pollen. We found that carbon dioxide levels may have a much larger impact on pollen increases than the temperature in the future.
