Both are true. Fires are a natural part of the environment. When you constantly put out fires around urban areas a lot of the excess brush just builds up, inevitably causing the mega-fires we see today. Huge fires are not as common in Europe mainly because Europe doesn't have as many forests as the west coast of the US.
But there's also a ton of evidence that we've had some of the warmest years on record in the past decade. The fires around the Bay area were started by a record-breaking heatwave. And temperatures in the interior of California regularly get above 40 C during the summer, so that combined with no rainfall means a lot of fires every year
