Scientists have used satellite data from NASA-built Landsat missions to confirm that more than 20 years of warming temperatures in northern Quebec, Canada, have resulted in an increase in the amount and extent of shrubs and grasses.
But I fear more shrubbery will just lead to more demands for shrubbery.
Update: What if the knights who say "Ni!" expand in number in a hotter future world? What if shrubbery just encourages them to expand their ranks? What then? Why isn't this debated? Why don't we hear about this danger? Why the cover-up?
