NOAA’s annual Arctic Report Card illustrates a warmer, wetter, and increasingly wonky Arctic climate.

Dissolved carbon dioxide may have bubbled up from magma far below Earth’s surface, contributing to prolonged warming.

Advances in plate tectonics research allow a deeper understanding of how greenhouse gases escape from within the planet.

A thick portion of Earth’s crust may have capped the Samoan plume and suppressed volcanism for 30 million years, explaining a curious gap along the Samoan chain.

Not all climate models include carbon from thawing permafrost, and those that do often disagree. Scientists are working to better inform models and assess how these crucial materials are simulated.

Flowing brines transport heat more effectively than old models showed, potentially changing climate simulations.

Cristales australianos apuntan a la existencia de agua dulce, así como de continentes que se elevaban sobre el océano Hadeano de la Tierra.

Geochemical sleuthing amid acid mine runoff suggests that scientists should rethink an isotope signal long taken to indicate low levels of atmospheric oxygen in Earth’s deep past.

Researchers sampled sediment cores and found that where magnetite was abundant, methane-producing bacteria were as well.
