I know, but, but on average across the globe that would be like a frozen Earth, Right. So greenhouse gases are great. The problem is that in the last 150 years, and in particular in the last several decades, we have been increasing those greenhouse gases very rapidly. And that that is resulting in increased temperatures on the globe which are then having these other side effects of, you know, sea level rise, you know, fires, all kinds of impacts and really impacting life on the planet, impacting us humans, we primarily live near coastlines and so on, but impacting other life on the planet as well. So the global warming problem is real. The solution to global warming is non trivial. There are several routes we could go and many of them are promising and so on, but politically some of them are really difficult. Even if we agree to have, for example, solar energy, the kind of technical things of how you distribute that energy, how you store it, battery storage, all of that, some of that is non trivial. The thing about nuclear weapons and that being a political decision, is that once the political decision is made to eliminate them, the eliminating them isn't actually that difficult. So that's the really good news, because we already said if there were 70,000 of them in 1986 and today there are 12 and a half thousand, that means we were able to eliminate them. Some of that was actually used to fuel nuclear power plants, and some of it is just the dismantlement. And then you still have the waste problem and so on. But much better to have a waste problem from nuclear weapon material than to have them blowing up, right? So the one piece of good news is it is a political problem and humans can solve political problems again. And it's something we created and something we're able to dismantle. The other piece of good news is that we do have a treaty, actually. It's called the Treaty on the Prohibition of Nuclear Weapons. This is something that diplomats have been working on for many years. So that said, that Treaty currently has 99 states, UN member states, states that are either party to the treaty. That means they've gone through the kind of process of ratifying the treaty. That means their national legislation typically did something or they have signed the treaty. So more than half of the UN member states. Are the nine that possess nuclear weapons part of the treaty? No, they're not. And the big question is how to get them to that table. So, so from my perspective, the US really has an absolutely fundamental role to play in all of this. We were the first to develop nuclear weapons. We're the only country to ever use them on cities full of women and children. And we wrote the playbook for the Nuclear testing era. We were in the Marshall Islands six months after the attacks on Hiroshima and Nagasaki, asking the people of Bikini island to move so that we could test nuclear weapons in their islands. I mean, just really, really devastating history. But that's our legacy. That's what we, the United States, have done. And then everybody else, in some sense you could say, follow suit except for the use of nuclear weapons in time of war. And so my view is that the United States really has a role to play in leading the world. Now, how do you lead the world? I love your example of what parents would do with rowdy teenagers and so on. To me, leading the world is always and must always be about setting an example. If you're a parent who's on their phone all the time and you tell that same teenager not to be on their phone all the time, it's not going to happen. Right? Like, how do you as a country lead on having a world that is free of the nuclear threat, which I would argue is most acute for the United States, I imagine a world free of nuclear weapons in which the United States is actually much safer because we've got the oceans, we've got the geographies on our side, we've got the conventional military. As critical as I may be of the spending and everything associated with that, this really could be an incredibly safe country. And in fact, with nuclear weapons, we're incredibly vulnerable. And we're vulnerable to a very small and relatively poor country called North Korea because they now have about 50 warheads and they have intercontinental ballistic missiles that are estimated to be able to reach any part of the United States. So it's forget all the morality and ethics and responsibility. Forget all of that for a moment and just say that actually we'd be better off in a world free of nuclear weapons. So that's what we're going to do. Pursue. And then you have to put yourself into what does that leadership look like? How do you lead by example? How do you show respect for other states, for other countries? How do you show respect for international law? I don't think we're doing a very good job, especially at this time. But we really in some sense haven't done a good job on that in a long time. The US really has this now 80 year history since the end of the Cold War, of playing this role of world policemen and being involved in all kinds of conflicts and all kinds of wars. I mean, there are estimates out there that of its entire history, 250 years, the US has not been involved in wars. For. For less than 20 years of that. Right. So that's not a good kind of backdrop, but we could change. And part of the way where changes have happened in the past is by one, having a general public that's aware and two, having a general public that gets really engaged on these things. Things. When it comes specifically to nuclear weapons, there really were two periods of progress, is how I would put it. One was the 1960s, which gave us the Partial Test Ban Treaty. That's what basically halted all the atmospheric tests. So all of this fallout that went all around the planet. Right. Was halted. It was primarily US and Soviet Union tests that were the largest. The UK also stopped testing in the atmosphere as a result of this treaty. This was in 1963. And there was a tremendous amount of public engagement on this at the time. From the Nevada Test Site, there was fallout that had reached basically all corners, essentially going from Nevada, going east. So just because of how the winds are in the United States, very little of it went west of the Nevada Test Site, most of it east of the Nevada Test Site. And there was this effort to actually document, speaking of your young child, to document strontium 90 in baby teeth. And this started out at Washington University, St. Louis, Missouri. It was actually a group of mothers who became very concerned that their babies were drinking milk which contained strontium 90s. Strontium 90s, a radioactive isotope. It's similar to calcium. So it ends up in the milk and then it gets incorporated into. Into baby teeth. And they were doing these analysis and finding Strontium 90. Mother's parents were sending. When, you know, the tooth fairy visited a child, they would send these in little, you know, packets. They would send the baby teeth labeled with the date of birth. And they actually found a kind of correlation between when a child was born with respect to the atmospheric testing that was taking place and how much strontium 90 they were finding in their teeth. Just unimaginable. But in any case, that ends up being a kind of real public engagement effort that also convinces Kennedy to pursue the Partial Test Ban Treaty. And then that takes place in 1963. And then by 1968, we also had the Nuclear Non Proliferation treaty. Then the 70s were very turbulent, Vietnam, all kinds of other things happening. And then by, in 1980, Ronald Reagan comes back or wins the election and he's, you know, going full on, you know, cold Warrior nuclear weapons and so on. And in 1983, Reagan watches the film the day after. You should watch it sometimes. I actually watched it not that long ago. I didn't think it was very good, but apparently in 1983, this really made a strong impact on people. 100 million people watched it. It was a TV movie. The 100 million people watched, including Reagan, made a big impact on him and he decided he wanted to do something about nuclear weapons prior to that. A million people walked in Central park in June of 1982 against the nuclear arms race. So you have this, and then by 86, Reagan and Gorbachev are in Reykjavik and they're actually discussing eliminating nuclear arsenals, which sadly didn't happen because they ended up disagreeing over the missile defense system that Reagan had hoped to build, called Star Wars. Nowadays, actually, Trump wants to build the Golden Dome. It's just as doomed as Star wars was back in the 80s and just not a good use of money. And it's really only going to actually fuel a nuclear arms race rather than constrain it. But in any case, back to my original point, we need people to understand what's at stake and we need them to engage and we need to make, we also need to make progress on these more fundamental issues of war and peace. Because as long as these countries are in such either open or indirect conflicts, they're not necessarily going to be sitting down discussing, let's eliminate all nuclear weapons. But that is quite simply what has to happen so that, you know, my children, who are older, but your son, so that they can have a future. We need them to have a future. And I also, you know, you don't have to have children to think that this is really important. I mean, the ultimate survival of humanity has somehow got to be something that people actually not just become aware of, but actually are ready to do something about.
