Ceres: Missing Craters, Crust Thickness Variation by Interior Convection
Models show that several puzzling features about Ceres’ topography, gravity anomalies, and crater size distribution may be explained by asymmetric hemispherical convection due to radiogenic heating.

Less Air Travel May Partially Contribute to Global Warming
Decrease in aircraft soot emission, as shown by COVID-19 lockdown, leads to a significant increase in ice crystal number in cirrus clouds, and results in a small global positive radiative effect.

What Caused the Open Habitat Transition in the West-Central U.S.?
Between 26-15 My ago, forests covering west-central North America gave way to open, grassy habitats. Now, oxygen isotope records suggest this shift is owed to drier winters and increased aridity.

Air Pollution Was Reduced During the COVID-19 Pandemic
A decrease in emissions of ozone precursor gases during the COVID-19 economic downturn likely explains the unusual reduction in ozone concentrations observed during the spring and summer of 2020.
