Common sense? Ain't nothing common about it.

Populists - like Donald Trump - love to appeal to 'common sense', while pushing ideas as contentious as they come. But what does Trump get right about how he talks to people about big ideas - and what can everyone else learn from it? And what does all this mean for how to talk about something as complex and polarised as climate change?

In this episode I'm joined by Dr Dannagal Young, Professor of Communication and Political Science at the University of Delaware. Danna is the author of 'Wrong: how Media, Politics, and Identity Drive Our Appetite for Misinformation'. We talk about her amazing work on the psychological underpinnings of political tribes, including how much any of us actually like to think about complicated things at all.

These new-format episodes take a long time to record, script, and edit. If you like it - that'll make me happy.

Is climate science 'neutral'? Should it be? Are humans even capable of being neutral about anything?

In this new-format episode, I dig into accusations that climate scientists risk undermining their work by going on climate marches. Can that really be true? Doesn't the scientific method speak for itself? And is it realistic to expect people to spend all day immersed in awful data, and NOT want to change the world afterwards?

I'm joined this episode by the fab Dr Lydia Messling, climate engagement expert and a very thoughtful and clever person. Lydia talks about her experiences in being told not to go on climate marches, and what she's learned about how climate scientists can be great public communicators. And Lydia helps me understand the big big difference between being 'neutral' and being 'objective': while the former's probably impossible in science or life, the latter is the very heart of what makes science fab in the first place.

This is a new type of episode that I hope will be the norm from now on. But it takes a lot longer to do. So if you want to see more like this, let me know - hello@yourbrainonclimate.com and please do leave a review. And do please consider chucking a few quid at www.patreon.com/yourbrainonclimate.

When it gets hot, we all get a bit stroppy: think 'shouting at people on the internet' stroppy. But that's only the tip of the (melting) iceberg. Too much heat can trigger or make worse a range of mental health conditions. And what does climate change bring? More heat. So what are the mental health implications of rising global temperatures?

Joining Dave this episode is Dr Alessandro Massazza (X / LinkedIn) - Policy Advisor for United for Global Mental Health. Ale tells Dave all about what the science has to say about the very many ways getting too hot can fry your state of mind - and why it's time to give mental health a proper seat at the climate table.
