We synthesize insights from 2+ decades of research on how uncertainty shapes optimal climate policies and affects the SCC. Our main takeaways:

Is social media to blame for teens’ mental health decline?
Intuition says yes—but RCTs find only small short-term effects when users quit.
This new preprint argues these studies don’t prove social media isn’t to blame.
Here’s why: 3 reasons.

Experience curves indicate that successful technologies reduce in cost by ~20% for each doubling of cumulative production.
However, we find that past learning rates are not very predictive of future learning rates, throwing many energy tech cost projections into doubt.

September 2025 was the third warmest on record in the Berkeley Earth dataset. But this downplays how anomalous it was; without 2023 and 2024 this year would have been well above any prior records and well above the long-term trend:

Lave avgifter på nye og dyre elbiler er neppe den mest treffsikre elbilpolitikken i den fasen vi er i nå. Å styrke virkemidlene som stimulerer til å eie og bruke elbil kan gi både bedre klimaeffekt og fordelingsprofil. Har skrevet om elbilmomsen i Aftenposten.

Norska Miljöpartiet (MDG) klarade 4%-spärren genom en aggressiv kampanj för rödgrön taktikröstning. Bra folk men partiet står dessvärre för katastrofal energipolitik som skulle leda till mer avindustrialisering, avfolkning, finansialisering – noll progressivt. Där hoppas jag andra står emot.
