Climate change obviously plays a role, but it's not the primary driver.
I think some activist groups and the media are purposefully muddying the water on this issue.

I don't condone dishonesty or propaganda, but using these events to help point out that a) climate change is really happening, b) it's not just a few extra hot days during the summer, seems perfectly okay.
The consequences of bad forest management from earlier decades will still play out for a while longer, but now that the correct policies are in place, it will cease to become an excuse, while the consequences of climate change are only going to worsen. Forests have been increasingly drier and hotter. Logging activity has cut down the most fire resistant trees and replaced it with flammable young ones. Trump suggests to increase logging and blame the liberals. When politicians blame forest management from a century ago, it is an argument in bad faith, as a way to ignore the myriad impacts of climate change. We should be constantly improving our forest management, yes, but it's something already being worked on, while there is so much resistance to policies to reduce climate change.
FWIW, here in BC the 3 summers that we had fires coincided with the record beating heat.
