It is time to move from quiet tolerance to active advocacy for transgender, gender non-conforming, and non-binary scientists, because lives are on the line, says Laura Fattaruso.

An article in Global Change Biology finds that ecosystem production and respiration of a 100-year-old aspen forest shows a decreasing sensitivity to temperature over a 21-year period.

Sam Woor discusses how optically stimulated luminescence dating is used to date the relics of ancient landscapes

An article in JGR Solid Earth uses numerical models to explore the conditions required to form thick, cratonic lithosphere in a relatively hot Archean mantle.

Andrea Stoellner explains how differential mobility particle sizing (DMPS) can help identify the sources of airborne plastic particles.

Albert Larson describes the use of neural networks to enhance the resolution of satellite data and provide a more detailed understanding of water cycling.

Vanessa Sun describes the use of sensors linked to a low-cost computer in air quality monitoring.

Kristian Chan describes how airborne ice-penetrating radar can be used to map ice layers.

Caleb Walcott explains how geographic information systems (GIS) are used to reconstruct past glacier surfaces, which in turn can be used as a paleoclimate proxy.

An article in Water Research investigated the rates, microbe types and main drivers of dark carbon fixation within intertidal sediments from the Yangtze Estuary, China.

The EU needs an integrated nutrient directive that regulates the agricultural application of nitrogen and phosphorus to prevent ecosystem degradation and support the Farm to Fork initiative. This directive must go beyond the current, inadequate regulations by considering nutrient balances and accounting for regional differences.

Ryan Glaubke describes the use of fossil foraminiferal Mg/Ca as an ocean paleothermometer.

An article in Monthly Weather Review reports that typhoon-induced sea surface cooling can weaken typhoons and lead to their early termination.

Vince Davidson Pacañot tells us how life cycle assessment is used to compare the total environmental impact of different energy systems.

Aileen Doran explains how clumped isotopes are used to constrain hydrothermal fluid temperatures and compositions during the stages of ore mineral precipitation.

Following record-level declines in 2020, near-real-time data indicate that global CO₂ emissions rebounded by 4.8% in 2021, reaching 34.9 GtCO₂. These 2021 emissions consumed 8.7% of the remaining carbon budget for limiting anthropogenic warming to 1.5 °C, which if current trajectories continue, might be used up in 9.5 years at 67% likelihood.

An article in Earth and Planetary Science Letters explores the physical and structural properties of a deep magma ocean during Earth accretion.

Human mobility was drastically reduced during COVID-19 lockdowns, and could surge beyond pre-pandemic levels as restrictions ease. A classification scheme enables robust comparative analyses of pauses and pulses in human mobility — from anthropauses to anthropulses — providing invaluable insights into anthropogenic environmental impacts.

Antarctic sea ice extent reached a new record low of 1.965 million km² on 23 February 2022. This extent is approximately 32% below climatological values and might indicate a transition to new, more extreme, annual fluctuations.
