DE temporarily cuts gasoline & diesel taxes: -expensive -not really progressive -mutes oil-saving incentives -encourages other countries to do the same -resulting lack of demand response leads to higher oil prices Why are more sophisticated solutions deemed infeasible, politically/administratively?

New out in @EnvironResLett: Do citizens, experts, and policymakers believe the EU will meet its 2030 climate targets? #ClimatePolicy #EUClimateLaw #FitFor55 #ClimateCommunication #BeliefGaps
Climate politics sounds increasingly polarised. But in Europe, support for climate isn’t driven by die-hard supporters or opponents. It tends to be shaped by a large “conditional middle” (33%).
The @ligo.org and @egovirgo.bsky.social collaborations officially announced the first direct detection of gravitational waves #OTD in 2016. Hard to believe we are ten (ten!) years into the gravitational wave era of astronomy and astrophysics. A remarkable tool for understanding our Universe. 🧪 🔭 ⚛️

Climate change has an impact on the oceans, which in turn affects humanity, including our economy. In this recent paper, we quantify these impacts www.nature.com/articles/s41..., led by @bbastien.bsky.social with @francescogranella.bsky.social @maxtav.bsky.social within @sparccle.bsky.social project

Most of these damages come from non-market values: nutrition, coastal protection, and the existence value of marine ecosystems — not just market losses.
The Social Cost of Carbon for the Oceans is out today in Nature Climate Change. www.nature.com/articles/s41... Until now, ocean damages have been largely missing from SCC estimates used in climate policy.

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)...

Excited to announce a new @pnas.org publication on the Social Cost of Carbon. We integrate evidence from the literature and expert survey to provide an SCC distribution inclusive of both parametric and structural uncertainties. Our mean 2020 value is $283 per ton CO2 www.pnas.org/doi/10.1073/...
Synthesis of evidence yields high social cost of carbon due to structural model variation and uncertainties | PNAS
Estimating the cost to society from a ton of CO2—termed the social cost of carbon (SCC)—requires connecting a model of the climate system with a re...
