Humans to Trees: Drop Dead

This from an article in the New York Times entitled, Environment Blamed in Western Tree Deaths:

"Rising temperatures and the resulting drought are causing trees in the Western United States to die off at more than twice the pace they did a few decades ago, a new study has found."

Of course, the environmental issues contributing to the trees' problems—drought, rising temperatures, extended summer weather—might just possibility have something to do with human behavior. So I'd have framed the headline somewhat differently; it seems the environment is being wrongly accused here.
