Human‐Impacted Natural Ecosystems Drive Climate Warming

Current greenhouse gas budgets do not account for most indirect anthropogenic impacts. In this perspective, we call for attention on anthro-natural greenhouse gas (GHG) fluxes and their mitigation me...

Upgrade to global #wetland including #peatland database and map

David Olefeldt @olefeldt.bsky.social · Jun 4

This new map provides a global view of the distribution of a multitude of aquatic ecosystems, including various wetlands. It's a pretty big step forward, and I look forward to seeing how it will be used e.g. to study wetland greenhouse gases.

Excited to share our new paper led by Tsinghua Uni ECR Zhang Han: www.science.org/doi/10.1126/.... New model based on eco-evolutionary optimality explains observed seasonal and spatial trends in stem respiration, implies stem CO2 efflux down by >25% by 2100, reducing land carbon emissions.

Thermal acclimation of stem respiration implies a weaker carbon-climate feedback

The efflux of carbon dioxide (CO2) from woody stems, a proxy for stem respiration, is a critical carbon flux from ecosystems to the atmosphere, which increases with temperature on short timescales. Ho...
