Human activities pushed global warming to 1.37C in 2025, and the rate of heat building up in the Earth's system is intensifying, scientists say.
The annual "indicators of global climate change" update by leading scientists finds clear evidence the world is continuing to heat, with global warming set to surpass a key threshold of 1.5C in about four years.
Under 2015's Paris Agreement, countries agreed to limit global warming to "well below" 2C above pre-industrial levels and to pursue efforts to curb temperature rises to 1.5C.
