Canada

The bigger problem is the hotter and dryer conditions.

Yes, that's definitely a part of it. We've neglected to do controlled spreads of fire to limit these wildfires from being as devastating to the local ecosystems as they are. We're also just getting off a particularly dry spring for the provinces, so that kindling's ready to burn. This of course is accelerated and worsened by climate change. CBC has a whole article about the changing of our wildfires as its impacted by climate change. It's a good read and I'd encourage you to check it out.

That's part of it but there is more to the story ...

-- a big change in logging activities, where previous practice was using brush piles (from delimbing trees) that were burned in winter was stopped (to save money), and instead a "where it drops, it stays" practice began, leaving massive amounts of dry fuel for fires to feed on (right around 2000-02 it changed)

-- a failure of gov't regulation to match tree planting numbers to equal the number of trees harvested

-- global warming that raised winter temperatures, which allowed pests to survive in larger numbers than ever before and decimated wide swaths of pine/spruce (BC is a prime example)
