Multi-year La Niña–El Niño transition influenced Earth’s extreme energy uptake in 2022–2023 - Nature Geoscience
The extreme Earth heat uptake in 2022–2023 was mainly driven by the transition from multi-year La Niña to El Niño and a positive energy imbalance linked to human-induced warming, according to multi-mo...

The majority of hydrogen in Earth’s core is likely to have been incorporated during the planet’s formation, rather than through comet impacts, according to a study in Nature Communications. The findings suggest that the core may be the largest reservoir of hydrogen on Earth. ⚒️ 🧪
Experimental quantification of hydrogen content in the Earth’s core - Nature Communications
Earth’s core is arguably the largest reservoir of hydrogen (H) on the planet. Experiments show that H sequestration is coupled with those of Si and O, enabling the core to store the equivalent of dozens of Earth’s oceans.

Contemporaneous mobile- and stagnant-lid tectonics on the Hadean Earth - Nature
Geochemical data from zircons show that subduction-like processes were operating contemporaneously with stagnant-lid-like processes at different locations as early as 4.4 billion years ago on the Hadean Earth.

A universal concept for melting in mantle upwellings - Nature
The first melts generated in any solid-state mantle upwelling are kimberlitic CO2-rich silicate melts that form at about 250 km depth through oxidation of elemental carbon to CO2.
