This article includes graphs of two different methods for measuring the Earth’s temperature – one in the lower atmosphere and the other at ground level. Although these show different absolute temperatures and different trends over time, since 1995 they both show a similar trend – little or no temperature increase. The author states he selected 1995 as there have been no major volcanic eruptions since then which would skew the temperature with a cooling effect.
So why, if CO2 increases cause temperature increases, and atmospheric CO2 has continued to increase over this time, haven’t temperatures continued to noticeably increase?
The answer – man made CO2 is NOT influencing the Earth’s temperature!
