Posted on January 31, 2020 by ...and Then There's Physics

20 years of hockey sticks

Posted on April 22, 2018 by ...and Then There's Physics

I wrote this post and then, after a discussion with Kevin Anchukaitis on Twitter, I took it down. I was tempted to not repost it, but thought I’d rewrite bits and have another go. I keep forgetting how controversial this … Continue reading →

Doomsday scenarios

Posted on July 13, 2017 by ...and Then There's Physics

There’s been a bit of a furore over an article called The Uninhabitable Earth by David Wallace-Wells. The goal was clearly to investigate some of the extreme scenarios, but – unfortunately – the article got a number of things wrong … Continue reading →

Toys, pram, out!

Posted on April 9, 2017 by ...and Then There's Physics

It seems that Roger Pielke Jr is having a bit of a rant on Twitter about an interview Michael Mann gave about the recent Congressional Hearings. He accuses Michael Mann of lying about him and also suggests that he might … Continue reading →

Hearing about climate science and the scientific method

Posted on March 31, 2017 by ...and Then There's Physics

I’ve been travelling and so haven’t really had much chance to keep up with what’s going on. I have, however, finally managed to watch the Congressional Hearing on Climate Science: Assumptions, Policy Implications and the Scientific Method. It was all … Continue reading →

Another hockey stick

Posted on February 26, 2016 by ...and Then There's Physics

Climateball(TM): re-energised

Posted on October 27, 2015 by ...and Then There's Physics

Apart from writing some blog posts here (and thanks to MT and others, I’ve had to write fewer than normal) I’ve largely been staying out of the whole online climate debate; ignoring the ClimateballTM mantra that the only losing move … Continue reading →

Michael Mann and Bill Maher

Posted on August 12, 2015 by ...and Then There's Physics

Given that some are promoting a despicable book about Michael Mann (you can read Greg Laden or Sou’s posts if you want some context) I thought I might post this recent Bill Maher interview with Michael Mann. It’s short and … Continue reading →
