According to a study published Monday in a journal of the National Academy of Sciences, the pollen season is getting longer, more intense and more intense as a result of climate change.
Scientists from several universities led by William Anderegg in Rutgers examined pollen measurement data dated between 1990 and 2018 and found that the pollen season increased by 20 days during this time period, while the amount of pollen in the air grew 21 percent.
“We find widespread advances and lengthening of pollen stations (+20 d) and increases in pollen concentrations (+ 21%) throughout North America, which are strongly coupled to the observed warming,” he says. the study summary. “Our results reveal that anthropogenic climate change has already aggravated pollen seasons in the last three decades with the detrimental effects of respiratory health.”
“This is a clear example that climate change is here and it’s in every breath we take,” Anderegg told the Associated Press, which first reported the study.
Scientists around the world have warned that the environment should be limited to warming by 2 degrees Celsius to avoid the most catastrophic effects of climate change.
A study published earlier this year indicated that greenhouse gas emissions already into the atmosphere could push the earth to exceed this limit over the next few centuries.
