These perspectives can be useful. But when we turn climate change into a blame game, there is no end to it. People are not really fighting about the numbers. They’re fighting about what numbers they should be using in the first place. If they don’t agree on that – which they often don’t – the fight goes nowhere useful. This battle has plagued international climate agreements for decades. The US and EU blame China and India, who then pick another (very reasonable) metric and fire it back.
