I'll come on to them.

It's supposed to be me as a doctor.

Hi, Adam.

How are you?

I am in shorts, yes, at home, yes.

So, yes, I created a graphic called the climate stripes, which is a very simple representation of changes in temperature over time.

Just using simple colored stripes going from dark blues back in 150 years ago to bright reds today.

We've already had to change the colours over the last couple of years because they've been so hot to add extra colours to represent the extreme temperatures over the last couple of years.

Yeah, we often tend to find the records further inland.

And I think Yeovilton's actually just beaten the Gosport record as we speak.

Yeah, so 1976 was certainly an extraordinary heatwave for its time.

We had 15 consecutive days where somewhere reached 32 degrees and that's an unprecedented length for a heatwave.

It came at the end of a year-long drought and I think that's what made it so memorable was that many people were queuing at standpipes for water in different places around the country.

There were lots of wildfires, some of the schools were shut, and so on.

So yes, it was an extraordinary heatwave for its time.

But obviously, as Justin says, the world has warmed over the past 50 years by about one degree since 1976.

But the important point to note is that that does not mean that our heatwaves have got just one degree hotter.

For southern England, what we've seen actually over the last 50 years is those heatwaves have got three or four degrees hotter.

So the extremes are getting hotter much faster than you might expect if you're just talking about global averages.

So that means that those 15 days above 32 in 1976 would be 15 days above 35 today.
