Aachoo

Sneezing and more is going to get worse say climate scientists at the University of Michigan. They just completed a study of 15 different plant pollens in the United States and used computer simulations to calculate how much worse allergy season will likely get by the year 2100. As the world warms, allergy season will start weeks earlier and end many days later — and it’ll be worse while it lasts, with pollen levels that could as much as triple in some places.

When the weather gets warmer, plants start blooming earlier and keep blooming later. Then, you have additional carbon dioxide in the air from burning fuels such as coal, gasoline and natural gas, which also helps plants produce more pollen.

The rise in pollens is not new. A study a year ago from different researchers found that from 1990 to 2018, pollen has increased and allergy season is starting earlier, with much of it because of climate change. Also, the pollen season is starting earlier. Already about 30% of the world and 40% of American children suffer pollen allergies.

The big sufferers from allergies are 25 million Americans with asthma.
