Scientists have identified 27 global warming accelerators known as amplifying feedback loops, including some that the researchers said may not be fully accounted for in climate models. Scientists said that the findings added urgency to the need to respond to the climate crisis. In climate science, amplifying feedback loops are situations where a climate-caused alteration can trigger a process that causes even more warming, which in turn intensifies the alteration. The international collaboration, led by Oregon State University (OSU), US, researchers, also provided a roadmap for policymakers aiming to avert the most severe consequences of a warming planet, they said. The findings have been reported in the journal One Earth. The study in all looked at 41 climate change feedbacks. The report warned that interacting feedback loops may result in a sequence of catastrophic climate "tipping points," where changes to climate systems become self-sustaining.
