Experts say pollen season will be longer, worse this year

Climate change has already made allergy season longer and pollen counts higher, but you ain't sneezed nothing yet. Climate scientists at the University of Michigan looked at 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. It's enough to make allergy sufferers even more red-eyed.

FOR THIS INTERESTING ABODE SUNDAY MARKS THE FIRST OFFICIAL DAY OF SPRING AND WITH THE WARMER AIR COMES ALLERGIES, MILLIONS OF AMERICANS HAVE ALREADY BEEN SUFFERING. SEASONAL ALLERGY SYMPTOMS BEFORE SPRING HAS EVEN SPRUNG. MARIANNE RAFFERTY EXPLAINS WHY. >> THE FIRST OFFICIAL DAY OF SPRING IS RIGHT AROUND THE CORNER. AND SO ARE THE ALLERGIES CONGESTION POSTINGS WILL WATERY EYES. SNEEZING IS USING ALL DAY, BUT THANKS TO CLIMATE CHANGE. THE WARMING PLANET IS MAKING OUR WINTER SHORTER, ALLOWING TREES, GRASS AND FLOWERS TO BLOOM EARLIER AND GROW FOR LONGER PERIODS OF TIME ON TOP OF THAT, SCIENTISTS SAY EXCESS CARBON DIOXIDE GENERATED FROM BURNING FOSSIL FUELS HELPS PLANTS MAKE EVEN MORE POLLEN. >> POLLEN SEASONS HAVE STARTED STARTING NOT 20 DAYS EARLIER AND THERE'S ABOUT 20% MORE POLLEN IN THE AIR. IT'S BAD NEWS FOR ALLERGY SUFFERS, BUT IT'S JUST THE TIP OF THE MELTING ICEBERG CLIMATOLOGIST AT THE UNIVERSITY OF MICHIGAN SAY ALLERGY SEASON WILL ONLY KEEP GETTING WORSE USING POLLEN SAMPLES FROM 15 DIFFERENT PLANTS AND COMPUTER SIMULATION TO CALCULATE THAT BY THE YEAR. 2100 POLLEN LEVELS ARE EXPECTED TO TRIPLE TAKE WHY BEEN A DRONE? AND IF YOU'RE ONE OF THE COUNTLESS AMERICANS TURNING TO ALLERGY MEDS FOR SOME RELIEF, DOCTORS HAVE SOME RECOMMENDATIONS. >> WE KNOW THAT THE INTRANASAL STEROIDS SPRAYS, WHICH MANY ALLERGIC SUFFERERS ARE ON, MAKE A BIG DIFFERENCE. IF THEY'RE STARTED 2 OR 3 WEEKS BEFORE THE SEASONAL ALLERGY SEASON. MEANWHILE, EVEN THOUGH FRESH AIR IS NICE ALLERGY SPECIALISTS A LIMIT HOW MUCH YOU OPEN YOUR DOORS AND WINDOWS WITH THE WINDOWS CLOSED IN THE AIR CONDITIONING ON. YOU CAN CUT DOWN ON THE POLLEN COUNT BY 90% OR MORE. AS MARIANNE RAFFERTY. REPORTING ALLERGY SEASON IS NOW EXPECTED TO START AS EARLY AS VALENTINE'S DAY EACH YEAR FOR PORTIONS OF THE COUNTRY WITH
