That's not how it works. Learn from the Common Core Climate Practice Model:
You can fit the data from ftp://ftp.cmdl.noaa.gov/ccg/co2/trends/co2_annmean_mlo.txt to the quadratic function

cco2/ppm = 0.0134*t^2 + 0.5202*t + 310.44 (t years since 1950)

t = 65 --> 400.86 ppm (2015)
t = 150 --> 690 ppm (2100)
dcco2/dt = 0.0268*t + 0.5202
t = 65 --> 2.26 ppm/a (2015)
t = 150 --> 4.54 ppm/a (2100)

∆T/K = k*ln(cco2_1/cco2_0)

Assuming all warming is attributable to CO2:
k = 0.8/ln(400/280) = 2.24 K (∆T 0.8 K from 1850 to 2015)
∆T = 2.24*ln(690/400) = 1.22 K (2015 to 2100)

2°C goal achieved.

Standard 62.1–2007 ventilation rates may result in indoor levels up to 2,100 ppm above ambient outdoor conditions. Thus if the outdoor concentration is 400 ppm, indoor concentrations may reach 2,500 ppm with ventilation rates that meet this industry consensus standard. Concentrations in poorly ventilated spaces can be found even higher than this (range of 3,000 or 4,000).
