This is just one more inconsistency in the global warming scam.

The AGW crowd claims there has been a global temperature rise of 0.5ºC
over the last 60 years and that this is due to increasing CO2.


The science is simple:

If 200 - 400 PPM = +0.5ºC
then 400 - 800 PPM = +0.5ºC

Therefore, if the 2070 projections are correct (another doubling of the
CO2 concentration), then total temperature increase would be 1.0ºC
compared to 1900 temps.

That's the science.


You are forgetting something. The oceans and atmosphere are *big* and
take time to heat up, current estimate is that the lag is about 30 years
or more (and even that's not taking into account deep ocean
temperature).

In other words most of the temperature rise from the 200 - 400 CO2
increase hasn't happened yet.
