Question 434828: how can i find when the co2 ppm will double the preindustrial age of 280ppm
with 2000 being x=0 2001 is = to 1 and so on untill 2200
in the year 2000 co2 ppm 364 and 2050 is 467 and 2100 is 600ppm, 2150 is 769 and 2200 is 987
with F(x)= Ca^x

how can i find when the co2 ppm will double the preindustrial age of 280ppm
with 2000 being x=0 2001 is = to 1 and so on untill 2200
in the year 2000 co2 ppm 364 and 2050 is 467 and 2100 is 600ppm, 2150 is 769 and 2200 is 987
with F(x)= Ca^x
------
F(0) = C*1 = 364
-----
F(50) = Ca^50 = 467
---
The a^50 = 467/364
a = 1.004996
----
So your equation is
F(x) = 364*1.004996^x
------
Doubling occurs when 1.004006^x = 2
---
Solve for "x":
x = log(2)/log(1.004996)
----
Solve:
x = 139.09 years
