Planet Mercury’s radius probably reduced by no more than 2 km since the Late Heavy Bombardment, with a strong hemispheric dichotomy in contractional strain, suggesting the loss of interior heat over time is less than expected for a small rocky body

Multiple climate contributors to fire risk in southeast Australia have led to an increase in fire extent and intensity over the past decades that will likely continue into the future, suggests a synthesis of climate variability, long-term trends and palaeoclimatic evidence.

The seasonal evolution of the Afro-Asian monsoon system from the continents to oceanic regions has changed through the Holocene due to variation in seasonal insolation resulting from orbital forcing, according to a data-model synthesis.

Changes in monthly temperature extremes are governed by mean climate warming, whereas changes in monthly precipitation extremes respond more to changes in variability, suggest analyses of large-ensemble climate simulations.

Total erupted volume and umbrella cloud radius can inform estimates of eruption characteristics and volcanic explosivity more reliably than column height or volume alone, according to simulations of the eruption of Pululagua, Ecuador, 2,450 years ago.
