If you care about the world we are handing on to future generations, the news on Thursday morning was dramatic. This January was the warmest on record; temperatures in 18 of the past 19 months have exceeded pre-industrial averages by 1.5C. There can be no comfort that the epoch-changing climate crisis is 20 or even 10 years away. It is already upon us.
Temperatures should have been moderated this winter by cooler air over the Pacific; it did not happen. Scientists are bewildered and scared. James Hansen, doyen of climate crisis research, believes that, unless this pace of deterioration is reversed, warm ocean waters flowing from the southern to the northern hemisphere will be trapped as vast sea currents cease. Sea levels will rise to impose a civilisational threat. It is a global imperative to dial down the rate of carbon emissions.
