And one of the guys looked at me and he says, the secret is that in order to learn how to grow any species, we have killed that species at least twice.

Now, we started this science show with the news that the king of mangoes, the Alfonso, has been devastated in India by a weather phenomenon called El Nino.

And we haven't really had a chance to dig into that, which I can do now with the help of the BBC's audio archives.

So according to the UN this week, the poor mango season was just the beginning.

A new phase of the El Nino weather pattern could begin in a matter of weeks.

But how does an El Nino start?

From the BBC World Service's Inside Science last week, here's Amanda Maycock, a climatologist from Leeds University, with the beginnings.

So that oof was from host Roland Pease because six degrees above the normal ocean temperature is a lot.

And normally, if you've got above two degrees above ocean temperature, you can expect an El Nino.

And that's the two degrees above is the borderline for a super El Nino.

So how this happens is that this weather party has moved a whole load of extra heat and water vapour from the west side of the Pacific Basin to the east.

And this has global implications.

Michael, Sandy, what does an El Nino year mean for your bit of the world?

Yeah, so here in Southeast Asia, El Nino is expected to hit us pretty bad this summer.
