Editorial statement
I approved the justification of handling topic editor.
Short summary
Arctic and alpine tundra ecosystems are warming rapidly, yet measurements of ecosystem CO₂ respiration remain limited. We compile in situ respiration measurements from warming experiments across 64 Arctic and alpine tundra sites. By integrating fluxes with climate, vegetation, and soil data, this database improves understanding and prediction of how tundra carbon cycling responds to climate warming and feeds back to the climate system.
