Global warming worsens allergies though the weather condition seems nice. Seasonal allergies are now causing many sinuses to swell.

Global warming causes polar ice caps to melt, strengthen hurricanes, raise sea levels and a worst direct effect is gets more people to sneeze frequently, Live Science reported. Over the years, study finds the effects of mounting carbon dioxide and bringing a warmer atmosphere causing subdue in environmental changes.

Research Associate in Environmental Science and Engineering at Harvard University, Christine Rogers commented on the worse effects of global warming and how it brings allergies. "There has been the significant increase in allergies and asthma in recent decades, which obviously cannot be explained by any changes in genetics.

According to The Verge, more than 36 million Americans suffer from seasonal allergies causing eye-itching, sneezing, and even more. This is because global warming leads to longer blooming seasons, grow more trees faster and increase carbon dioxide levels in the air resulting in lots of allergy-causing pollen.

Aside from an increase in photosynthesis and early advancing the season, more molds are also produced and global warming is the utmost seen reason behind. Carbon dioxide levels elevate further causing intense allergies and more intense rainstorms. "Exposure to fungi is very clearly associated with both allergy and asthma symptoms," Rogers said.

It's how global warming directly causing allergies to worsen in an almost epidemic condition. Everything will have supposed to go the way it should be, but wind pollination is not very efficient. Thus, ragweed pump billion-odd grains of pollen, but only few land on the female flower.

So, during summer it's the grasses and weeds which will cause allergies, while in the spring, the trees and plants and in the fall, it's the ragweed. More than the ways mentioned how global warming could worsen allergies, there are other affecting factors. Then, it's best to keep stocks of antihistamines as allergies continue to round up and circulate.
