Studies quantify Arctic feedback emissions and mangrove wave defense

· Climate

New research finds permafrost, wetland, wildfire and freshwater emissions could amplify climate change by up to 30 percent. A separate study offers a way to predict how much mangrove forests diminish waves from severe storms.

Why it matters：Better quantification of natural feedbacks and coastal protection sharpens both emissions accounting and the case for conservation as adaptation infrastructure.

Key points

  • Thawing Arctic permafrost releases methane and carbon dioxide as locked organic matter decays.
  • The study frames these releases as part of self-reinforcing feedback loops.
  • The mangrove research focuses on waves from severe storms.
