You’d have to have the heart of Katie Hopkins not to be moved by the refugee crisis – a humanitarian disaster unfolding in front of our eyes. The reasons for this huge movement of people are many and some commentators have linked the mass movement of people to the impacts of climate change.

To me, this is wrong. Not wrong as in factually incorrect, but the wrong argument to make at the wrong time. It comes across as opportunistic bandwagon jumping when emotions are high – and will make the general public, the people we need to win over, less likely to hear the warnings on climate, not more – “There they go again…”

One of the reasons I don’t join pressure groups is this kind of one-eyed hectoring. It frustrates me when I hear it from all parts of the environmental movement from cycling lobbyists to anti-fracking militants (for the record I’m very pro-cycling and moderately anti-fracking). It’s fine if campaigners just want to feel good about themselves, but if they really want to make a difference, they need to be much better attuned to the public mood.
