Earth's Climate Has Passed Its First Irreversible Tipping Point and Entered a 'New Reality'

19 hours 20 minutes ago
Climate change has pushed warm-water coral reefs past a point of no return, marking the first time a major climate tipping point has been crossed, according to a report released on Sunday by an international team in advance of the United Nations Climate Change Conference COP30 in Brazil this November. From a report: Tipping points include global ice loss, Amazon rainforest loss, and the possible collapse of vital ocean currents. Once crossed, they will trigger self-perpetuating and irreversible changes that will lead to new and unpredictable climate conditions. But the new report also emphasizes progress on positive tipping points, such as the rapid rollout of green technologies. "We can now say that we have passed the first major climate tipping point," said Steve Smith, the Tipping Points Research Impact Fellow at the Global Systems Institute and Green Futures Solutions at the University of Exeter, during a media briefing on Tuesday. "But on the plus side," he added, "we've also passed at least one major positive tipping point in the energy system," referring to the maturation of solar and wind power technologies. The world is entering a "new reality" as global temperatures will inevitably overshoot the goal of staying within 1.5C of pre-industrial averages set by the Paris Climate Agreement in 2015, warns the Global Tipping Points Report 2025, the second iteration of a collaboration focused on key thresholds in Earth's climate system.
