But I was looking into the figures.

El Nino in 2015-16 was...

caused over three trillion dollars in economic damage.

I was thinking that's a lot and are there lessons to be learned from the past?

Here's geographer at King's College London George Adamson.

Yes, so collapse of the Egyptian empire and the England cricket team.

George Adamson mentioned Peruvian civilisations, which is interesting because in Peru, Edgar Bracamonte is director of the Royal Tomb of Sipan Museum.

And for the BBC's climate show, The Climate Question, here he is explaining how an early civilisation, the Moche, dealt with El Niño.

Yes, I think that that's exactly it.

These Moche had their capital, I mean, a good 50 miles from the coast, I think.

And there is evidence that they moved their capital there in response to a massive flood.

So it ended, and wouldn't you know, Michael, a super El Nino event is implicated.

So there is this really fascinating suggestion from ice core research that the warmer climate meant that the usual snowfall fell as rain instead of snow, and where they'd moved their capital to...

They were in this place that needed melting snowfall off the mountain to supply their water.

And instead of that, they got a flood for 30 days and then a drought that lasted 30 years.

And that did for them in the end.

So combine the effects of climate change with this year's predicted El Nino event and 2027 is set to be the warmest year on record.

If there's anything we can do to prepare for the floods, the droughts and the wildfires being forecast, it's always cheaper than rebuilding afterwards.

We started with a shortage of a delicious kind of mango and we've finished with some pretty strong global predictions for a super El Nino coming everyone's way.

I'm going to ask you both to pick your top fact from the show.
