How global climate change can make your allergies worse

A new study finds that climate change can have negative side effects for your allergies.

There are many obvious and negative effects that are the result of human caused global warming. There is an increase of strong weather patterns such as hurricanes, rising sea level and a greater amount of carbon dioxide in the atmosphere polluting our bodies. But what many do not know, and is the subject of a new study from the Weizmann Institute of Science in Israel, is how climate change can worsen allergies.

Naama Lang-Yona, an environmental science doctoral candidate from the institute, found that a very common fungus, known as Aspergillus fumigatus, has a tendency to develop allergic traits if they are growing in an area with high carbon dioxide levels in the air. While the fungus is found most often in a natural environment, it is certainly not limited in where it can thrive.

"Its natural habitat is decomposed biomass and soils, but you could find it in many other places, such as our walls, air-conditioning filters," Lang-Yona said in an email to the American Geophysical Union.

This is especially problematic for those who suffer from allergies. The side effects of this spore can range from mild symptoms such as sneezing, to more potentially fatal events like anaphylactic shock. The fungus works by sending out tiny spores into the human body that are covered with proteins, essentially getting the body to attack itself. While not all episodes involving this fungus are deadly, the risk is there.
