Are we in the midst of ‘climate change’ or a ‘climate emergency’? Personally, I don’t think there’s a debate.

My outlook is set towards emergency, forged on the groundswell of scientific research pointing that way and amplified by images of extreme weather events of recent months and years. But, because I rely on the testimony of experts rather than having any expertise myself, it is just an opinion. And one with which a lot of people argue.

Some reject that same scientific research I accept; some point to one of the (very few) expert reports running counter to my view; some put their faith in non-experts; and some simply don’t care.

The climate emergency – and by extension the move towards electrifying transport – is up there with Brexit, immigration, vaccination and more in its ability to divide.
