Most scientists agree: it’s too late to reverse, or even slow down, global warming/climate change. Too much energy has already been pumped into the atmosphere by greenhouse gases. Yet Al Gore and other environmentalists continue to argue that there’s still something we could do, just maybe. Of course we should stop polluting; pollution kills us and other living things. But climate change? Better to accept that it’s happening and that we ought to have done something about it decades ago.
