A Crystal Ball for the Carbon Cycle, But a Cloudy One
Carbon cycle models quantify relationships between emission scenarios and resulting atmospheric concentrations, but are the projections credible? New analyses find grounds for both hope and concern.

Reporting Model Results Even When They Cannot (Yet) be Tested
Models simulating the nitrogen cycle track its multiple chemical forms but tend to report a subset that can be compared with available field measurements.

Grow-Fast-Die-Young Strategy Increases Swiss Forest Biomass
Climate change and CO2 fertilization can increase both growth and mortality of trees. The net effect on forest biomass depends on that trade-off, which long-term studies in Switzerland reveal.

Unexpected Consequences of Solar Geoengineering
Solar engineering is not a substitute for mitigation, and concerns about its risks and unintended impacts are supported by the recent discovery of overlooked atmospheric chemical feedback.

Northern Ecosystems are Shaped by Snow
Changing climate in the Arctic leads to a shorter snow season but deeper snow in the depths of winter. Under the insulating snow, biological processes are accelerated leading to higher nutrient availability and carbon losses.

Low-Frequency Quakes Have Modest Effect on Slow Earthquake Cycle
Slow slip phenomena on subdaily scales, captured by seismic and GNSS data, show that low-frequency earthquakes are incidental to larger magnitude slow earthquakes, in which aseismic slip dominates.
