The past IS the key to the future. Fantastic effort - 485 million years of global temperature correlating with atmospheric CO2 in this new paper by Judd and others www.science.org/doi/10.1126/... . 🧪⚒️

Top panel shows two black wiggly lines going up and down in parallel- one is CO2 the other is global temperature. They cover the last 485 million years. Panel on the bottom left shows a x-plot of CO2 vs Global Temperature- the data are beautifully correlated implying an Earth System Sensitivity of around 8 oC per CO2 doubling. Not sure what the figure in the bottom right panel shows but it looks cool!

Woohoo, 25 follows more \o/ Thus, 5 more facts (the challenge was 1 fact per 5 more follows). Let's stay with gravity & the "Potsdam Potato". For newbies & as a refreshment for our longstanding followers: The link shows the Potsdam Potato, a model of Earth's gravity: youtu.be/7vnJntX6YOs 1/n

It's summer in the N hemisphere, take advantage of it to read Tektonika v.2-1 : tektonika.online/index.php/ho...#DOAJ#openscience#tectonics#geology ⚒️

Thanks for leading this effort, @geozwaan.bsky.social! And for involving me. 😀

📢 Paper alert! Are you interested in rifting and continental break-up processes, but also in associated natural hazards and geo-resources, and where future rift research may go? Check out our new #OpenAccess paper in @eurogeosciences.bsky.social's Solid Earth ! 😃 Link: doi.org/10.5194/se-1...

Another five followers, wow. So the challenge continues (for every 5 followers a random fact). Today: How diamonds reach the Earth’s surface. First, as most of you will probably know: diamonds are “baked” from carbon under extreme conditions 1/5

You might think the explanation for why some planets have no moons, and others have dozens or more, is simple. But there are two main theories that covers most scenarios, plus a third way that explains Earth's Moon.

Why Does Earth Have Only 1 Moon While Saturn Has 146?
Why Does Earth Have Only 1 Moon While Saturn Has 146?

You might think the answer is simple. But there are two theories.

📢 Paper alert! Are you into rifting? Check out our new study in Geology: we explore the delayed impact of mantle-controlled deformation during early-stage rifting by combining data from the NE Atlantic & analog tectonic models 😃 Paper: doi.org/10.1130/G523...

Distribution of rifts and sedimentary basins in the Northeast Atlantic domain in Late Jurassic times (145 Ma). CG—Central Graben; EGR—East Greenland Rift; HB—Hammerfest Basin; GGF—Great Glen Fault; HBF—Highland Boundary Fault; HFZ—Hardangerfjord Fault Zone; HT—Halten Terrace; IMF—Inner Moray Firth; MF—Moray Firth; MT—Moine thrust; MTFZ— Møre-Trøndelag Fault Zone; OMF—Outer Moray Firth; PB—Porcupine Basin; TZ—Tornquist Zone; VG—Viking Graben; WBF—Walls Boundary Fault. Modified after Skogseid et al. (2000), Coward et al. (2003), Erratt et al. (2010), and Schiffer et al. (2020). Inset shows main rift corridors during the Late Jurassic (150 Ma). D—Denmark; Fin—Finland; Ger—Germany; Ir—Ireland; NL— Netherlands; No—Norway; Pol—Poland; Por—Portugal; Swe—Sweden; UK—United Kingdom. Modified after Peacock (2004).
Overview of set-up and results from key analogue models from Zwaan et al. (2022) showing the impact of coupling between mantle and upper crust on rift basin evolution. (A) 3-D sketch of model set-up. (B) Top view sketch show- ing the orientations of the velocity discontinuity (VD), representing mantle inheritance, and seeds (S), representing crustal inheritance, in models B3 and B5. (θs = obliquity of seeds, θVD = obliquity of VD). (C) Cross-section sketch of model layer- ing and seed location, of which the natural proto- type is shown in (D). (E) Maximum normal strain (indicating active normal faulting) and topography analysis of models B3 and B5. The models under- went a shift from low to high coupling (as a result of increasing divergence velocity), leading to the initial development of crustal structures, con- trolled by the crustal inheritances, that are subsequently overprinted by a phase of mantle- controlled deformation. d—VD displacement.
