Default Are we being conned (again)

I concede that we have a world temperature increase perhaps! But
I'm very cautious about its cause.


Many years ago, well in the last 30 any. The amount of co2 in the
atmosphere was 300ppm + or - 10 now it is 350ppm why has not the
temperature increased by a similar amount? the average is about
290Kelvin why is it not 330-3340K????? Why am I a skeptic?????


This is a strawman argument. As far as I know no climate scientist says
that the average global temperature in degrees Kelvin should be proportional
to the CO2 fraction in the atmosphere starting from 30 years ago. The real
relationship is quite complex, don't expect it to say that a x% increase in
Co2 means a x% increase in temperature. Just because this relationship that
SG1 has presented fails doesn't mean anything about the reliability of
current climate models..


We have a strong La Nina effect at the moment.


Why do you say that? This mob:

say we are still in ENSO.

The debate will be enriched if we all take time to try to check facts before
posting.
