Trees and microbes team up to improve nitrogen nutrient processes in higher CO₂ conditions
Forest trees growing in air containing higher levels of carbon dioxide (CO2) radically change the way they "cycle" nitrogen, a key plant nutrient, with implications for forests as a nature-based climate solution.
What to take away

Good EarthRestored wetlands aren't clear-cut wins against climate change, study suggests
Wetland restoration is often promoted as a definitive way to support wildlife, improve water quality and help store carbon. However, new research from McGill University suggests the overall climate picture is more complicated. In a study of human-made marshes along the Bay of Fundy, researchers found that parts of these restored wetlands are releasing methane, a greenhouse gas 27 times more potent than carbon dioxide. The findings, published in the Journal of Geophysical Research: Biogeosciences, highlight the importance of addressing nuances and closely evaluating one-size-fits-all climate solutions.

New research from the University of Cambridge offers an easy and readily available solution using AI and satellite data. In a paper published in the journal Science of Remote Sensing, researchers used embeddings by Tessera, a geospatial foundation model, to successfully map tree species across the Trentino region of the Italian Alps.
