Medium-range estimates of Arctic carbon emissions could result from moderate climate emission mitigation policies that keep global warming below 3°C (e.g., RCP4.5). This global warming level most closely matches country emissions reduction pledges made for the Paris Climate Agreement...Phiddian, Ellen (5 April 2022). "Explainer: IPCC Scenarios". Cosmos.

"The IPCC doesn't make projections about which of these scenarios is more likely, but other researchers and modellers can. The Australian Academy of Science, for instance, released a report last year stating that our current emissions trajectory had us headed for a 3°C warmer world, roughly in line with the middle scenario. Climate Action Tracker predicts 2.5 to 2.9°C of warming based on current policies and action, with pledges and government agreements taking this to 2.1°C.Tasirin Canjin yanayi, na yanzu da na gaba, suna gabatar da manyan haɗari ga lafiyar ɗan adam, jin daɗi, da yanayin halitta.
