Soil microbial communities produced more water retaining molecules when enriched with insoluble organic carbon, chitin, compared to a soluble carbon source, N-acetylglucosamine.

Emulators—algorithms that fill data gaps—are traditionally used to project average temperatures and precipitation. This work shows that efficient emulators can substitute for costly simulations over a wide range of extreme indices.

PNNL researchers used the Global Change Analysis Model (GCAM) to explore 15 different global scenarios that consisted of combinations of five different socioeconomic futures and four different climatic futures.
