I understood that. None the less, We have been burning copious amounts of coal for a long, long while. It has been centuries of CO2 loading, and centuries of accelerating discharges.
It appears you dream Earth history but ignore Earth science.
The warming Earth has experienced since the LIA has been from natural climate controlling factors. Pretty plain to see.
The CO2-Centric scientists have inaccurate science that is being exposed, realtime.
Pre-industrial CO2 concentration was ~280 ppm. If natural climate factors are ignored then at the most the change from 280 ppm CO2 to 400 ppm CO2 has warmed the Earth ~0.8°C.
However at the highest point of said all CO2 warming of Earth, as CO2 was at 365 ppm and racing in an 18 year period to ~400 ppm, the Earth stopped warming.
In science that is called the hypothesis is disproved by real world observations.
In science the hypothesis gets tossed or taken back to academia to determine why it was wrong.
In a crazed CO2-centric science crowd the observations get tossed or twisted to fit the hypothesis.
The latest publication of siting station data by Watts at al in Dec 2015 shows over 410 printine data collection stations measurements since 1979. The data shows that "homogenized" databases, including the more recent Best record, present over estimated temperatures by at least 33% The reasons for the error are obvious to scientists who generate scientific information.
It is a time to examine information objectively, and scrutinize it morally and scientifically.
Corruption in today's science is prolific.
May I present the below as further evidence. ☺
