Urgent Action Needed to Save Corals from Global Warming

An international team, led by Dr. Liam Lachs, reveals that coral adaptation to ocean warming may not keep pace without drastic reductions in greenhouse gas emissions. Their study, using an eco-evolutionary simulation model on Palau's coral populations, highlights that natural selection could allow corals to adapt to rising temperatures but only if global warming is limited to 2°C per the Paris Agreement. Without this, scenarios predict a 3°C increase, risking coral extinction due to marine heatwaves. The team emphasizes immediate emission reductions and innovative coral management strategies, like assisted evolution, to enhance survival odds. Their findings emphasize the necessity of strategic climate action to preserve coral biodiversity and ecosystem functionality.
