To learn more, researchers — including School of Biological Sciences and School of Earth and Atmospheric Sciences Professor Joel Kostka — leveraged the SPRUCE experiment, where scientists can combine air and peat warming in a whole-ecosystem warming treatment. Peatlands build carbon stocks over centuries, but rising temperatures and atmospheric carbon dioxide concentrations rapidly changed the equilibrium at SPRUCE within a 4-year timescale, highlighting the vulnerability of these carbon-rich ecosystems to global climate change.
