Great interview of climate scientist Mike Mann and virologist Peter Hotez on the war on science by special interest groups. My colleague Mann endured vicious attacks after his pioneering (and solidly confirmed) ‘hockey stick’ curve of #globalwarming.

The thing about attacks is true, for sure. Have a look under any random post of mine on X since Musk took it over.
But it has been going on ever since I started communicating publically about climate 30 years ago as a young postdoc.

In reality, the prevailing view of climate science has always been to expect global warming, and warming has been predicted correctly since we have numerical climate models. See e.g. www.realclimate.org/index.php/cl...

I'm just preparing a talk on climate disinformation. Because Trump used it in his UN speech, I'm including the old story of the forged Time Magazine cover, supposedly showing that climate scientists predicted a coming Ice Age.
"Climate sceptics" don't have honest arguments so resort to fake news.

Excellent, well-informed new podcast! Like a ship entering a storm, we’re now entering the overshoot - a world above 1.5 degrees C #globalwarming. This requires a whole new mindset,
