My journey out of fossil fuel-funded research
Research on the energy transition needs to involve all communities and requires breaking the paradigm of traditional industry-funded research, argues Jef Caers from his personal story.

Fluocerite as a precursor to rare earth element fractionation in ore-forming systems
Experiments under simulated hydrothermal conditions suggest that the mineral fluocerite may serve as an intermediate phase that fractionates the rare earth elements in ore-forming systems.

Potential CO2 removal from enhanced weathering by ecosystem responses to powdered rock
The enhanced CO2 uptake by vegetation in response to powdered rock should be considered in assessing the feasibility of enhanced weathering as a negative emission technology in mitigating climate change, suggest simulations of a land surface model.

Southward shift of the global wind energy resource under high carbon dioxide emissions
Wind power for energy generation is projected to decrease in northern mid-latitudes and increase in the tropics and Southern Hemisphere, suggests an analysis of climate model simulations utilizing an industry wind turbine power curve.

Top-of-atmosphere radiative forcing affected by brown carbon in the upper troposphere
Brown carbon absorbs light, but its climate impacts in the upper troposphere are not well known. A series of aircraft observations in the US reveals that convection lofts brown carbon to high altitudes, causing greater warming than at lower altitudes.

Mobility and persistence of methane in groundwater in a controlled-release field experiment
Most monitoring of methane well leakage focuses on emissions of methane gas to the atmosphere. In a controlled-release field experiment, significant methane also persisted in aquifer groundwater due to lateral migration along bedding planes.

Potentially exploitable supercritical geothermal resources in the ductile crust
The brittle–ductile transition is thought to control crustal permeability. Laboratory experiments and model simulations show that permeability is also stress dependent and ductile granitic rocks may have enough permeability to host geothermal resources.
