so like a half a degree with a 6 degree increase.

But it's even less than 6 degrees. 6 degrees C is a linear relationship between CO2 concentration and temperature. That is how the IPCC incorrectly models it. From my link above it is a logarithmic relationship between CO2 concentration and temperature:





What the IPCC predicts with their models in red below and what is being observed and predicted in blue based on the logarithmic relationship between CO2 concentration and temperature:



This is a chart that is never published by agenda driven climate alarmists. It's raw NOAA U.S. temperature data and CO2 concentration measurements at the top of the volcano on the Big Island of Hawaii.

The raw data shows little to no correlation between temperature and CO2 concentration, especially at current extremely low concentration levels compared to the other atmospheric gases.
