This is true, but the relative magnitude of the change does matter, and it's very low over the last century, just 1.0 F. Even if it goes up 2.0 F in the next 40 years, it's still a relatively small change that is not likely to reduce forest cover in any measurable way. I'd worry more about human activities that are reducing forest cover at a serious rate.
