My first comment piece in @theguardian.com is on a topic very close to my heart; the threat that the #ClimateCrisis poses to my local community in South Wales.

I think this is representative of fossil-fuelled weather extremes reportage not just in Aus but in many countries, where (a) the cause, fossil fuels, is simply never mentioned and (b) the change is treated as essentially inevitable and un-mitigatable, all that's left is figuring out how to 'adapt'

A quick fact check on @skepticalscience.bsky.social tells us that:
"Polar bears are in danger of extinction as well as many other species"
Conclusion: Don't trust The Telegraph... and in other news: polar bears shit on ice.

Thought provoking 🧵. It's interesting that the examples here are often used in arguments as if they are a knockout blow - but both statements in each pair are true. It's just that one of them will feel more conclusive to you.
The optimist vs pessimist divide in #climate debates isn’t usually about the data.
It’s about how the same graphs are read, what people emphasise, what they discount, and how they interpret pace and stakes.
