I am sorry if I am being so obscure. I originally had not expected I would have to show that different climates have different impacts on wildfire, but that seems to be where questioning “climate change” has brought.
I would argue that like Oregon and Washington, it’s an issue made worse by intentional arson. If one wants to look deeper at this, I strongly suggest to look at a North America fire map which shows a definite difference between the degree of fires in the western US vs western Canada. If it was just natural causes, the two regions would not be as different as they are. But somehow, miraculously the fires in eastern Washington stop at the Canadian border. Climate change? I don’t think so.
@Zzyzx_Road here is using the change at the Canadian US border to assert that intentional arson is the cause of differences in rates of wildfires. I am accepting his unstated position that fewer Canadians are arsonists than Americans, though I did make one comment about that. (Fewer Canadian arsonists is the only way his comments make sense to me, but I may be misunderstanding)
Looking at the climate maps, it is obvious that the climate changes at the Washington/British Columbia border.
Semiarid eastern Washington has more fires than subarctic BC. This is a restatement of the part of Zzyzx’s remark that I italicized above, using the Köppen climate descriptors.
My contention is that semiarid climates have more and longer wildfires than subarctic climates. The change in climate at the border is natural and accounts for the differences between the two regions, contrary to Z’s assertion “if it was just natural…”
This change from one climate to another is not the same as climate change caused by global warming. In the one we change location, while in the other we change through time. But it does allow us to see the difference between different climates. We can reasonably conclude that if we change from one climate to another, wildfire behavior changes. We do not have to adopt an external agent to explain the fires, like Americans start more fires than Canadians.
Climate has an effect on fires. The change in wildfire behavior in CA shows that the climate has changed.
I hope that is clearer.
