Climate change: The 1.5C threshold explained

"Before the Paris Agreement there wasn't really a focus point for the world to aim for, to reduce the climate change process," says Pauline Dube, an environmental scientist at the University of Botswana, also a coordinating lead author on the IPCC's 1.5C report. "You don't need a model to know that, if you are that close, we're going to reach 1.5C in around a decade or so at that rate of warming," says Allen. Similarly, in 2022, Bill Gates said he saw "no chance" of the world staying within the 1.5C threshold, but believes innovation in climate technologies, such as forms of carbon capture, are promising solutions to climate change.
