Coral reefs are the first environmental system on Earth to pass a climate 'tipping point,' with widespread bleaching and dieback due to rising ocean temperatures, signaling an urgent need for global decarbonization to prevent irreversible ecological and economic damage.
Scientists have modeled a potential climate tipping point involving the collapse of the Atlantic Meridional Overturning Circulation (AMOC), which could lead to severe global climate repercussions, particularly impacting Europe. The collapse could result in a deep freeze in parts of Europe, with temperatures plunging by up to 30C, while the southern hemisphere would experience rising temperatures and changes in rainfall patterns. The study suggests that the AMOC tipping point could be closer than previously thought, but more research is needed to determine the likelihood and timeframe of such an event.
Researchers from the University of Bern have investigated the possibility of preventing the melting of the West Antarctic ice sheet by artificially dimming the sun through solar radiation management (SRM). The study found that while SRM could delay the collapse of the ice sheet, it cannot prevent it entirely. The most effective way to prevent long-term collapse is through rapid decarbonization. The study also highlights the high risks and unforeseeable side effects of geoengineering, including potential disruptions to the monsoon regime and ocean acidification.
A new study suggests that the Gulf Stream system, known as the Atlantic Meridional Overturning Circulation (Amoc), could collapse as early as 2025 due to global heating and the influx of fresh water from melting ice caps. The collapse of Amoc would have catastrophic climate impacts, including disrupting rainfall patterns, increasing storms, dropping temperatures in Europe, and raising sea levels on the eastern coast of North America. While some scientists caution that uncertainties in the data make it difficult to predict the exact timing of the tipping point, they agree that the potential collapse of Amoc is extremely concerning and underscores the urgent need for rapid cuts in carbon emissions.
