New study: Risk of 60 percent more difficult pollen seasons in the future

Rising levels of carbon dioxide mean faster and stronger growth if the grass has access to nutrients and water.

The researchers have developed computer models that can predict how the increased grass growth will affect future pollen levels.

The result can be disappointing for pollen allergy sufferers.

- We looked at how climate change would affect the amount of pollen in 10 to 20 years and could then see that it would increase up to 60 percent if the levels of carbon dioxide are doubled in the future, says Alexander Kunganskiy PhD in philosophy at University and Exeter, which is part by an international research team.

The researchers consider the newly developed research method to be unique, as it can be used both locally and globally.

Several previous studies have shown increased pollen levels in the future, but they have all been limited to a specific location. 

- Instead of experimenting and doing studies in different places in the world, you can now use one and the same research model that can reproduce all information, says Kunganskiy. 

As a consequence of elevated pollen levels, there is a risk that allergy sufferers develop more serious pollen problems.

Even more people can be affected and get a sudden pollen allergy. 

- It is a clear illustration that climate change can affect human health, says Kristina Ljungros. 

But according to Alexander Kunganskiy, the most important thing is to be prepared for any growth of pollen. 

- We have done this study to help in the research and we hope for a further development of the issue.
