It’s already later than we realize in the struggle to arrest climate change

A recent essay says the most pressing current scientific and political challenge is to avoid what is known as “dangerous” global warming – the point where world temperatures become irreversible.

As there’s a 25-to-30-year lag between greenhouse emissions and the full impact of their warming, current climate chaos is a result of carbon spewed in the late 1970s. The hit from more recent discharges – including China’s coal plants – is but pain yet to come.

So we’re dangerously close already.
