Predicting pollen levels in a changing climate

Anyone who has experienced seasonal allergies knows the suffering that comes with itchy eyes and blocked sinuses. Looking to the future, this discomfort may get worse, as Canadians are expected to face new allergens and higher levels. Climate change is bringing longer growing seasons, which means more pollen in the air. In this video, experts from Aerobiology Research Laboratories explain the increase in pollen they have seen in recent years, and how they are monitoring pollen levels to help Canadians respond and adapt.

Take Action

Climate change touches all of our lives, one way or another. Because it affects all aspects of modern life, there are many kinds of meaningful choices we can make that will help.

Climate change solutions start close to home, with simple actions in our own homes and families, but also involve new ways of thinking, planning, and acting in workplaces, neighbourhoods, and communities across the country.

See our "Take Action" topic for ideas and examples of innovative climate action taking place all across Canada.
