The earth is “tipping” towards a new reality: one where our climate could be drastically different. The Global Tipping Points Report’s new findings released last month reveal current climate dangers that pose risks to billions of people. Without urgent action, these dangers will lead to irreversible long-term effects to our planet’s stability.
Among these dangers is warm-water coral reef dieback. According to the National Environmental Satellite, Data, and Information Service, 84.4% of the world’s coral reefs experienced bleaching-level heat stress from January 2023 to September 2025. The report found that the tipping point for warm-water coral reefs is from 1.2 C (over 2 F) to 1.5 C (2.7 F), which has likely already been crossed. This dieback threatens hundreds of millions of people who depend on them. Coral reefs are important for providing coastal protection and supporting fisheries. Then, there’s the risk of the shrinking Amazon rainforest, melting polar ice sheets and weakening Atlantic Meridional Overturning Circulation (AMOC). All of these will further threaten millions by decreasing biodiversity, rising sea levels and undermining food and water security (plus plunging northwest Europe into severe winters if AMOC crosses its tipping point). When one tipping point is crossed, another will follow; many of them are interconnected.
The Global Tipping Points Report was targeted mainly to policymakers attending COP30, a pivotal United Nations climate change conference in Belém, Brazil. That conference ended on Nov. 21, and while it worked to mobilize additional finances for climate change, among other new initiatives, there was no clear commitment to move away from fossil fuels. With the world currently on track to increase global temperatures by 2.6 C (4.7 F) over the pre-industrial average by 2100, a huge overshoot of the Paris Agreement’s 1.5 C, tipping points seem inevitable. However, there is some progress already being made– what the report calls “positive tipping points.”
Since the last report released two years ago, the global adoption of electric vehicles, solar power, and wind power has accelerated. Battery prices have also plummeted by 84%, and more climate litigation cases, nature regeneration initiatives and sustainable consumption and production in food and fiber supply chains have emerged. These are all good signs, but to avoid crossing tipping points entails a lot more work. For example, the report suggests decisive policy action that can effectively finance climate change endeavors like electrification that work towards decarbonization.
“This is our new reality,” said Steven Smith, a lead author on the report, to Scientific American. While many tipping points remain uncertain, scientists stress the importance of working towards reducing them as much as possible because they affect billions in every region of the planet.
