There's no reason why you couldn't change that.

Why do we have people taking exams in June?

Yeah, it is.

And global cooling, air conditioning around the world, produces more greenhouse gas emissions than many countries.

It's a conundrum.

It's clear that we will need air conditioning in a lot of homes, but you can mitigate the impacts of that by not having it at too low temperatures, by only using it when it's necessary.

In this country...

We're not likely to need air conditioning all the time.

If we're telling people get air conditioning, we need to also be saying, well, you know, don't turn it up too much.

You don't need your home to be icy.

Give them kind of operating temperatures within that.

They've done that in France where they've said, actually, you know, don't have air con if it's below 26 degrees.

And, you know, that seems to work.

We need to prepare for the fact that we will need a lot more electricity.

Once you've accepted that, you know, all of our electricity needs to be low carbon and we need a lot more of it, then it becomes a bit easier, really.

There's a real danger here that the UK will become a much more unequal society as we become a hotter society.

And that's for a lot of reasons.

One is, you know, just affording air conditioning, affording to adapt your house.

Another is food.

Food prices are going to go up.
