Many climate change impacts have been observed in the first decades of the 21st century, with 2024 the warmest on record at +1.60 °C (2.88 °F) since regular tracking began in 1850. [ 19 ] [ 20 ] Additional warming will increase these impacts and can trigger tipping points , such as melting all of the Greenland ice sheet . [ 21 ]
