Critical elements in the Earth’s climate may be more likely to break down than previously thought, according to a group of scientists.
Their commentary in the journal Nature says there’s growing evidence that irreversible climatic changes could be triggered within a few decades.
The authors claim this could lead to a “climatic emergency” in which one shift amplifies another.
we must admit that we have underestimated the risks of unleashing irreversible changes, where the planet self-amplifies global warming," he says.
"This is what we now start seeing, already at 1C global warming.
“This provides strong evidence for declaring a state of planetary emergency to unleash world action that accelerates the path towards a world that can continue evolving on a stable planet.”
