Climate change is in the news. The fact that this is notable in itself is a travesty, but it’s promising that we seem to be there at last. People are on the streets, demanding not some abstract ‘peace and goodwill’ but rather their own future survival. People from across the political spectrum can get behind that. Without exaggeration it is a matter of life and death, and now that is being shouted from the rooftops. We have reached a crunch point, a decade or two too late perhaps, but we’re here now. There’s momentum, and it must be maintained.

It’s not often talked about, but there is a shameful secret amongst the environmentally enlightened. The very same people that conscientiously recycle, that cut meat from their diet, that put on a jumper instead of turning up the heating, often remain unwilling to change one significant part of their lives: flying. I myself am as guiltily as anybody. But there’s good reason. The world is more accessible than ever before and – let’s face it – we love it. Never has it been easier (or cheaper) to hop on a plane and find yourself somewhere exotic within a matter of hours.
