All right, this is Victor Alpha 3. Victor with the X-ray 4ID. I'll send it back to you, Ken. Now just one thing I should note is that when we see extreme stratospheric cooling, one of the problems that we've discussed this before is that you sometimes get the formation of what we call polar stratospheric clouds, PSCs, and these form roughly at about minus 78 degrees Celsius or cooler, And you'll get clouds that are composed of ice and nitric acid. And what will happen is these clouds look stunning, right? They're often iridescent, but they're chemically destructive. And because what they do is they basically provide a surface for inactive chlorine compounds, which are a derivative from CFCs, chlorofluorocarbons, to convert into active ozone-destroying forms, right? So they set off this chemical chain reaction that can then create a, you know, it'll eat up ozone, and you can add to the destruction of the ozone layer. We've been doing really well, where the ozone layer has been recovering really well. But PSCs, these polar stratospheric clouds, they form in these extreme conditions. And when they do form, that's a bad sign. Because some of them are water vapor based, but many of them can be chemically based. It's not water vapor based. And it's those ones that have the chlorine compounds that are the really destructive ones. because they'll go and they'll just chew up the O3, the oxygen up there, and the ozone up there, and you'll lose your ozone, and that's a problem. Okay, Ken, we'll send it back to you for neck control. I don't know if you want to speak to the polar stratosphere clouds or not, you can give a chemistry lesson, but I'll leave that to you.
