Metrics show Canada's wildfires, a natural part of its vast boreal forest, have worsened in recent years.

Wildfires are part of the natural cycle, and play an essential role in the regeneration of Canada's boreal forests, according to the Ministry of Natural Resources of Canada.

The global average temperature in June, July and August — known as the boreal summer in the Northern hemisphere — was a record-breaking 62.24 degrees, according to the European Union’s Copernicus Climate Change Service.

They also found similarly amplifying feedbacks in other permafrost-relevant processes, like the loss of boreal conifer forests due to fire -- but here, too, only at the local to regional scale.

The study found that boreal forests in the northern hemisphere are particularly vulnerable to negative effects of cleaning up aerosol pollution.
