Re: [asa] CO2 content

For one it should be marked as HEAVILY modified from Pearson and
Palmer (to the point of being completely fraudulent). There are simply
made up data points. Who produced this garbage? He or she should be
put onto your "do not trust" list.

  Here's the data

ftp://ftp.ncdc.noaa.gov/pub/data/paleo/climate_forcing/trace_gases/pearson2000_co2.txt

This is what it looks like from the paper (http://www.nature.com/nature/journal/v406/n6797/abs/406695a0.html
):

Note there is no gap from 40 to 23 mya in your graph nor error bars
(which are quite large). Speaking of 23 mya that's how far back you
have to go to get as much CO2 as we have now. For comparison sake the
Paleocene-Eocene Thermal Maximum (http://en.wikipedia.org/wiki/Paleocene-Eocene_Thermal_Maximum
) was 12 degrees C higher than our current temperatures. That spike
caused mass extinctions and ocean acidifications. So much for not a
problem.
