Earthquake hazard calculations for California’s coast are refined with a view of precariously balanced rocks that would have fallen if the largest predicted shaking happened in the past 20,000 years.

Ensemble Modeling of Coronal Mass Ejection Arrival at 1 AU
Heliospheric imaging data can be used in ensemble modeling of CME arrival time at Earth to improve space weather forecasts, treating the solar wind as a 1-D incompressible hydrodynamic flow.

Measuring Paleoclimate During a Deep-Time Deep Freeze
New application of clumped-isotope thermometry to 700-Myr rocks documents large climate swings related to Snowball Earth glaciation and offers better understanding of an earlier Earth system.

Committed U.S. Power Emissions Incompatible with Paris Agreement
Without a significant reduction in usage, committed emissions from coal and gas plants in the United States are already incompatible with the country’s pledges under the Paris climate agreement.

Can We Observe How Cloud Clustering Affects the Radiation Budget?
Satellite observational analysis confirms that lower-atmospheric stability and cloud clustering are major factors modulating the tropical radiation budget that had been suggested by modeling studies.

Soil Carbon May Not Remain Bogged Down in a Warmer World
Carbon was lost from an experimentally warmed boreal peatland much faster than it took to accumulate. Elevated CO2 had little effect on stored carbon, requiring re-evaluation of model assumptions.

Effects of Particles on Climate Remain Unsettled
Major advances have been made in the understanding of the physics and chemistry of particles, but major uncertainties remain in determining their radiative forcing effects on climate.

The Perils of Computing Too Much and Thinking Too Little
Big steps forward are synonymous with new ideas – a thought that merits mindfulness if we aspire to train students to do more than merely train machines.

Eruption and Emissions Take Credit for Ocean Carbon Sink Changes
A new model explains why the ocean’s capacity to take up carbon was reduced on a decadal scale, by accounting for reduced pCO2 emissions and ocean state changes due to the eruption of Mt. Pinatubo.
