Also scandalous they don't discuss implications. It's like reporting a widespread illness that is increasing human body temperatures, and understanding why, but failing to report that a body temperatures above 40 can be fatal.
Completely scandalous that the story about the last 3 years being the hottest on record, with an average a fraction under 1.5C, is judged to be only worth showing right at the bottom of the BBC News front page, under 'Also in the News'

News like this is a rare opportunity to communicate risks of where we are heading & consequences of our actions. Media largely sticks to global temperatures though - which doesn't tell the real story. Why? Stronger dialogue between media & science vital www.bbc.co.uk/news/article...
Global temperatures dip in 2025 but more heat records on way, scientists warn
The last three years were Earth's hottest on record, as humanity's carbon emissions continue to heat the planet.

This thread responds to Prof. Christian Dunn’s Telegraph piece on #climate communication.
I argue it misdiagnoses public disengagement, underplays escalating scientific risk, & reproduces a media narrative that has actively shaped, not merely reflected, public resistance to climate action 🧵

The utterly shameless & widely covered "report" out today, claiming net zero will "cost" £9tn is based on:
* Assuming free fossil-fuel energy, free petrol cars, free gas boilers, free gas power plants etc
AND
* Including climate damages in the "cost" of net zero
I kid you not, it is that stupid
* Assuming free fossil-fuel energy, free petrol cars, free gas boilers, free gas power plants etc

🧵A political/media guide to the "truth" about net-zero
1) Add up costs to install & run a net-zero energy system
2) Pretend fossil-fuelled alternatives wld be free
3) Do say "eco zealots are bankrupting us"
4) Don't say "free cars if we scrap net-zero" cos it sounds ridiculous
