	I think you have made two errors with your number below of “0.01% per year”.  So I ask for your source.

	Using round approximate numbers to make the computations simpler:

	a.   Present (2014) atmospheric CO2 concentration of 400 ppm
	b.   Ten years ago (2004)  “       “‘          “     of about  378, so the slope is about 2.2 ppm/year (call it 2 for simplicity, but getting closer to 3 ppm/yr recently)
	c.    Dividing  2 ppm/yr by 400 ppm gives 0.005 or 0.5% per year.  (would get a larger number if using something less than 400)
	d.    But this is not the right computation.  We should be comparing to the excess CO2 - not the total CO2.  The organization 350.org is suggesting that we need to remove 50 ppm from the atmosphere  (it will get worse).   But this would then give 2/50 = .04 or 4% worse very year.    Or 100% in 25 years - the year 2039.

	 The ratio of 4% per year to your 0.01% per year is a factor of 400 difference.  I look forward to your computation
