So fading away, I don't know if we, I think it's a new phase of the conversation that we're entering now as these become visceral impacts.

There does seem to be scientific shock and a certain amount of political shock at the moment.

Whether that's sustained is an interesting question.

I mean, as the situation becomes worse, the rate and speed of which action needs to be done becomes faster.

So it becomes more economically challenging.

I think that's a problem.

I mean, to be honest, I think the question is...

I want to come back to the actions part of the paper.

From your perspective, perspective in Australia, what is it that makes this such a critical component of the recipe for a food crisis in the whole region?

Normally, Australia and Asia receive good summer rainfall from easterly winds across the Pacific.

During an El Nino, which is a regular feature of the climate system, those winds reverse and the winds become westerly and they drive water towards the Americas.

Due to changes in the ocean vertical circulation there, the water becomes much hotter.

in the eastern pacific and so there's a measure of El Niño which is a band of water on the equator near the Americas and as that water gets warmer and warmer that is a measure of the El Niño and because the ocean surface water is warmer that then heats the atmosphere so associated with El Niños is normally record high temperatures because of this transfer of heat from the ocean to the atmosphere.

So that's one thing.

The second thing is it means less rain for Australia and Asia.

Well,
