"The Paris climate agreement requires that countries work to limit global warming to well below 2 °C, and pursue efforts to limit it to 1.5 °C, to avoid devastating climate tipping points."
"The latter target requires drastic action, even when assuming a small temporary overshoot that is combated by draw-down of atmospheric carbon to lower temperatures later in the century - a presumed best-case scenario for most climate scientists."
The Paris climate agreement requires countries to limit global warming to well below 2 °C and to pursue efforts to limit it to 1.5 °C to avoid devastating climate tipping points. The 1.5 °C target demands rapid and deep reductions in greenhouse-gas emissions across energy, land use, and industry. Even a small temporary overshoot of 1.5 °C would require active draw-down of atmospheric carbon later in the century to return temperatures beneath the threshold. Reliance on overshoot plus future carbon removal assumes optimal deployment of negative-emission technologies and creates high risks if removal is insufficient or delayed.
