A study of Global Water Futures Observatory site Sibbald Fen shows that sudden warming events like chinooks can trigger bursts of CO₂ from mountain peatlands—even in winter. As winters warm, this hidden carbon loss could grow. www.nature.com/articles/s41... @envwaterloo.bsky.social @water.usask.ca
Map of Sibbald Fen in the Rocky Mountains of Alberta, Canada, with a detailed view of the eddy covariance tower footprint processed for January to October 2021. Maps were produced in R [55] using the ggplot2 [56], sf [57], ggspatial [58], and rnaturalearth [59] packages. Elevation data were retrieved via the elevatr package [60].

A new study by GIWS alum Magali Nehemy shows that in the dry season, Amazon trees recycle recent rainfall from shallow soils by rapidly transpiring it back into the atmosphere. This sustains the forest and contributes to “flying rivers” that help maintain rainfall across South America.
