He's after a deal, a deal on the nuclear deal that he pulled the US out of in 2018. And it's a really crunch moment for that deal. It's essentially moribund because the US pulled out of it. But there have been attempts to revive it. And it expires this year. It was negotiated over 20 months, I believe, under the presidency of Barack Obama. But it is due to expire in October.

And at that point, any sanctions that the signatories could put on Iran for not abiding by the terms of the deal will no longer be possible to use. So it's a key moment. And there has been a flurry of recent diplomatic activity, three tracks. Iran and the IAEA, then Iran and European countries and Britain, actually four tracks.

Then there were talks last week, last Friday in China with Iran and Russia. And then finally, you have this letter from Donald Trump delivered last Wednesday. We don't know the contents, but there have been some interesting comments today from a foreign ministry spokesman in Iran saying, saying that they're not going to release the contents. They will respond to it after proper scrutiny.

But the messages coming from the US are contradictory and inconsistent because the Americans are expressing readiness for dialogue while also imposing new sanctions. But the message from Donald Trump that we know of because he's spoken about it in a television interview is negotiate or else. If you don't do a deal, there's the threat of military strikes. So Iran has got a lot to think about.

It certainly is in a weakened position because of those Israeli airstrikes last year, which targeted air defences around the nuclear facilities. And you know that the Israelis have lobbied for a long time for military strikes against Iran's nuclear facilities.

Now, they insist they are peaceful, but there is a huge amount of international concern, alarm even, at what the Iranians have been doing over the past few years to Experts say it would now take less than a week for the Iranians to enrich enough material for a single nuclear weapon. So that's a very short time frame.

It would take them longer to actually weaponize it, but they are enriching uranium at a very, very fast pace. to 60%, you need 90% to build a bomb. But there is a huge amount of concern. So you've got a flurry of diplomatic activity. I mean, Donald Trump wants deals wherever he goes, doesn't he? But the Iranians do not like negotiating with a gun to their head. So let's see what happens.

The Arctic's at its lowest ever as we go into winter. The Antarctic's at its second lowest ever as we go into summer. And in some ways, that's not surprising. But the specifics, I guess, are quite surprising in terms of those happening together and just how large the differences are from usual.

And yes, while the Arctic started to really look very different about 15 years ago in 2007, the Antarctic, it's only the last five years that we've started to see these quite big changes in Antarctic sea ice. Prior to that, it wasn't really declining. It was increasing a little bit.

I guess the key thing to remember is that Antarctic and Arctic sea ice, they vary each year anyway, right? So they're freezing up and melting each year. So anything that changes that freezing and melting process each year will change how much sea ice you end up with in the winter or the summer.
