To claim that global warming will be good for humanity
is to turn a blind eye to the many negative impacts.
The most common argument along these lines is that
carbon dioxide is ‘plant food’, implying that CO
emissions are a good thing. This ignores the fact that
plants rely on more than CO to survive. The “CO
fertilizer” effect is limited and will be quickly
overwhelmed by the negative effects of heat stress
and drought, which are expected to increase in the
future. Over the past century, drought severity has
increased globally and is predicted to intensify in the
future. Plants cannot take advantage of extra CO if
they’re dying of thirst.
