At TFL, we're making journeys safer for everyone, and that includes improving safety on London's

roads. That's why we and London boroughs are lowering more speed limits to 20 miles per hour,

because 20 miles per hour roads have already reduced collisions resulting in deaths or

serious injuries by 24%. That is how we're making journeys in London safer and brighter for everyone.

Thus ends the Chicago portion of the show. Chicago may be one of the cities not totally

beset by the worst heat wave. I was thinking a lot about the weather as I'm sure you have been,

and I was thinking back to my conversation that I conducted with Michael E. Mann. He is a

pen professor, an expert on climatology, and also, and this is part of his remit as a professor,

an expert on communicating around the issues of global warming and climate change.

And I recently had an interesting Twitter exchange that was, I think, in many ways,

pressaged by this conversation you're about to hear. And after the conversation, I'm going to

come back, and I'll read some of that Twitter exchange. But, you know, maybe I'll tip my hand

in a little bit by saying, he blocked me. Why did he block me? Very much because of issues

that were raised concerns of mine that we discussed very even handedly in podcast form,

but when it comes on Twitter, it's, I guess, a block, a thrust, a parry. So first,

listen to this Michael Mann interview from a couple of years ago, and then I'll read the Twitter

exchanges of that recently occurred.
