1. In a GREAT paper (why isn't it published??), Anthoff, Dennig & @johannesemm.bsky.social show that most IAMs have a hidden goal of a uniform price and define Negishi weights to arrive at that goal. Yet, carbon price should grow at the discount rate (at least under a carbon budget constraint)...

Results: By 2050, direct CO₂ emissions drop ~65% in buildings & ~70% in transport (vs. current policies).

A vicious cycle of global warming, climate extremes, higher energy demand (esp. for cooling), thus further emissions and warming makes early-on mitigation even more important. Check out our new paper with @FranPieC @edecian @jackjackk1

#BeyondGDP is an important concept. Can #happiness or subjective well-being based on surveys provide an indicator at the macro level? We argue it might, finding strong economic, environmental and social explanatory variables drivers. and SSP simulations.
