Is climate change responsible for increasingly frequent or severe cold events?
The evidence suggests it is not.
Instead, the impact of climate change is warmer winters and less severe cold events.
@hausfath.bsky.social has a great post on The Climate Brink talking about this.

Updating our Sherwood et al 2020 paper with these new LCM and Pliocene estimates gives a best estimate equilibrium climate sensitivity of 2.8C, with a 90% range of 2.1C-4C per doubling CO2. This is down from the original 3C (2.3C-4.7C) in Sherwood 2020.

Recent assessments have found the last glacial maximum implies a climate sensitivity of 2.4C (1.4C to 5.0C): www.science.org/doi/...
And the Pliocene implies a sensitivity of 3.1C (2.3C to 4.7C): www.pnas.org/doi/10....
Paleoclimate evidence generally provides the strongest constraint on high ECS.

Cycle lanes and LTNs often attract loud opposition, making them seem deeply unpopular. But are they?
Across multiple studies (survey + analysis of 36k UK tweets), we find broad support - especially for well-designed, segregated lanes. Good quality cycle lanes benefit all!

Why do people support or oppose bike lanes? Our research sheds light on public opinion
Research suggests that more consultation about cycle lanes would bring more support for them.
