Around 420ppm will be the approximate CO₂ concentration in 2100.
The Intergovernmental Panel on climate exchange finds that if CO₂ emissions keep at current fees, projected CO₂ stages by means of 2025 will reach about 470 ppm, 550 ppm by way of 2050, 700 ppm by using 2075, and approximately 950 ppm via 2100.
