Great @scitalkofficial.bsky.social episode with @djspratt.bsky.social on what's wrong with our climate policy makers. David suggests some just don't (want to) get the problem. And I totally agree. Giving away new oil & gas licenses is a death sentence to people.
As an energy expert, I say go solar!

Today, at 1.5 and 430 parts. Per million 302, climate change is already dangerous. That is, 1.5 is a political goal, not a moral goal.

We have just lost 15 years.
1.5°C is here 15 years faster than policy makers thought it would be.
The IPCC risk analysis, the mitigation, the emergency management you know policy is
based on 1.5°C in 2040.

From a risk management the worst case is relevant (plane crash..)
Policy makers, science, IPCC, doesn't look at the worst case scenarios.
Policy IPCC look at the middle range only.

So in a consistently rising sequence of numbers an average over 20 past years understates current situation? That is, it is an indication of the trend 10 years ago? If warming has accelerated to ~0.3C per decade isn’t the current situation the average over last 20 years + 0.3C? Serious question.

As some have suggested the last 10 years plus projections of next 10 years would be more realistic. 2023 was 1.5C. 2024 was 1.6C and first 3 months of 2025 was 1.65C. It is wilful blindness to adhere to a reticent measure and not see that in practical terms we have arrived at 1.5C.

In a rising sequence of numbers an average over 20 past years will always understate the current trend. That’s the norm #climate scientists have adopted and it is reticent.

But @djspratt.bsky.social's critique gets at how scientists themselves might be underestimating risks. There are multiple reasons for this, he explains: methodological, political, and social.
