Climate Change is Affecting Pollen Allergies

I know it's been miserable around here and everyone I know is complaining about allergies. What are your thoughts on climate change and the effect on allergies and asthma? 

Climate change is a major issue for environmental health as well as public health. Warming temperatures contribute to longer and more severe pollen seasons. That makes respiratory diseases worse. So this week, the Asthma and Allergy Foundation of America joins nearly 20 other organizations in signing a statement called

Experts believe climate change is to blame for making allergy season last about three weeks longer, and it's also becoming more intense.

"Allergenic plants are very receptive to those changes, so we're seeing robust plant growth and pollen growth and this translates into high pollen counts and terrible seasons all around," Dr. Neeta Ogden, an allergist and spokesperson for the American College of Allergy, Asthma, and Immunology, told "CBS This Morning."

What pollens are prevalent during which seasons, and how are climate factors affecting them? Ogden says these are the main factors to watch out for:

Spring: Tree (starting earlier this year)

Summer: Grass (will linger longer)

Fall: Ragweed (will grow faster)

    I have to wonder if there is something to this, other than just correlation.  I feel like each year, I hear people say their allergies are worse than previous years.  This year I have even heard people complain of allergy symptoms when they previously had none.

    Longer and more intense   Personally every year I say my allergies are getting worse than the prior year, and also hearing from others that have never suffered from allergies are now suffering.

    This year I started with a new symptom- red, itchy eyes- which as been manageable with allergy eye drops but was not 'fun' at first!

    It is good to see actions being advocated for, like helping to cut carbon pollution and other greenhouse gases.
