Daily briefing: Corals have been pushed beyond an irreversible tipping point, says report

""We have the knowledge" to prevent breaching climate tipping points, says political scientist and co-author of the report Manjana Milkoreit."

""What we need is a kind of governance that matches the nature of this challenge.""

""measuring something that tells you there's something wrong; we have to act""

Surging global temperatures have caused widespread decline of coral reef ecosystems, marking the first identified climate tipping point. Without rapid reductions in greenhouse-gas emissions, additional Earth systems such as Amazon rainforest dieback will likely cross irreversible thresholds. Some positive tipping points, including the transition to solar and wind power, are already advancing and could generate cascading environmental benefits. The IUCN red list identifies multiple Arctic seal species at extinction risk, reports widespread bird declines, and records several extinctions alongside a few conservation recoveries. Digital-twin technologies and tools such as Crane Radar are increasingly applied to biodiversity monitoring and forecasting.
