2 solutions:

1. US resolution to accept global warming as real, with commitment to lower emissions on top of forest management resources in both countries (US wildfires occasionally annoy Canadians)

2. US buys more Canadian Pine lumber.

We have reached a global warming tipping point where forest fires are at such extreme levels for 3 years in a row now, that fires offset global natural carbon capture from trees, which is about 1/4 of human emissions. Some of the arson, has been motivated by climate disinformation as "attempts to prove global warming is false by arson". Global warming's impact on forest fires is not more ignition. It is faster/wider spread of fires.

If everyone in Canada were employed as an "arson preventer", they could patrol 10 hectares of forest each.
