Is the Fight Against Climate Change Losing Momentum?

The morally right side doesn’t lose the crucial battles: the arc of the moral universe is long, but it does bend toward justice. We know that lesson too well, which may be a problem, in that it gives us undue confidence. The Intergovernmental Panel on Climate Change tells us that we need to cut carbon emissions by nearly fifty per cent by 2030 in order to have a chance of meeting the targets set in Paris in 2015—and 2030 is five years and nine months away. It’s not impossible.
