I don't know what you're saying, Leonard.

Probably, that is because you don't know what you're saying
or that you don't have the language skills to communicate it.

The 0.79 correlation I've documented between atmospheric
CO2 concentration and global mean surface temperatures
is strong.

The least-squares linear regression value shows indeed a very
strong signal-to-noise ratio. As atmospheric CO2 increased, global
temperature increased. The trend is sub-linear and statistically
significant.

Alarmist nutcases like "Leonard" just hate the fact that
scientists know what they are doing and publish their findings
even when those findings are politically incorrect.

TO REPEAT MY LEAD POST IN THIS THREAD:
There is a very strong correlation between CO2 and
global mean surface temperatures. Please see:

=-=-=-=-=-=-= The Data =-=-=-=-=-=-=
The CO2 data are the yearly averages of the monthly data
from the Keeling curve measured at Mauna Loa, available at:

ftp://ftp.cmdl.noaa.gov/ccg/co2/trends/co2_mm_mlo.txt

The global mean temperature data are the GISS adjusted
J-D yearly land and sea average, available from NASA at:

http://data.giss.nasa.gov/gistemp/ta...LB.Ts+dSST.txt

I plotted the data and calculated the R^2 values. The Goodness Of
Fit correlation is strong enough to show causation with a noice
value of about 20%. The temperature anomaly we currently observe
is likely 80% due to CO2 and 20% due to other causes. Just five
years ago it was 70% and 30% respectively.
