LIGO Detected Gravitational Waves from Black Holes On September 14, 2015 at 5:51 a.m. Eastern Daylight Time (09:51 UTC), the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Wash...

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. πŸ§ͺ πŸ”­ βš›οΈ

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

Most of these damages come from non-market values: nutrition, coastal protection, and the existence value of marine ecosystems β€” not just market losses.

The Social Cost of Carbon for the Oceans is out today in Nature Climate Change.

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)...

Agreed. Socioeconomically optimal values have been found at roughly 83%. And even then, political and social implications need to be anticipated and addressed.
NB: Even the 55% target has not yet been digested. We found people believe the EU will only manage 43% by 2030. More Credibility is needed.

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

Demand-side strategies provide climate benefits!

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
