This is The Guardian.

Every year we're experiencing record-breaking heat pretty much.

Our country just isn't prepared for this level of heat.

There's also a phenomenon happening called El Nino.

It turbocharges heat waves. It's predicted to be a super El Nino. If the El Nino hits, we're

likely to have very hot summer next year. The UK has recorded the hottest day on record in

May as an early heat wave engulfs Europe and serves as a reminder of how the climate crisis

is affecting lives.

From the Guardians today in Focus, this is the latest with me, Lucy Hoff.

Well, joining me is Helena Horton, Guardian reporter, previously an environment reporter,

so well qualified to help us understand this heat wave, these unprecedented temperatures

recorded for May. I don't know about

you, Helena, but I was tossing and turning all night. We were close to a tropical night in London

where temperatures don't dip below 20 degrees, but that was narrowly averted. But nonetheless,

there have been record temperatures recorded in London, but also around the country. Can you

give me a sense of how hot it's been? Well, it was record overnight, so it's very, very rare that

we get anything up to 20 degrees. It was just nearly 20 degrees in London last night. Actually,

we've never had that in May before. So if you did find it hard to sleep, these are temperatures

we'd normally have in August.

And obviously in May we have quite long evenings.

So it takes longer for the house to cool down.

It's just very uncomfortable.
