Radical-green, progressive Democrats are now resorting to intimidation and inquisition tactics to force others into conformity with their anti-science regarding climate change. Due to their failing miserably in winning the actual science debate, they turn to coercion on those whom disagree.
Unfortunately, they conveniently ignore (or are unaware) the empirical evidence that climate change is a constant, which has produced ancient and geological era extremes in weather and temperatures - extremes that science has confirmed with a cornucopia of peer-reviewed research.
These extremes even took place eons 'Before Exxon' (BE), the fossil fuel giant that Democrats routinely blame for modern climate change and global warming.
Above is a paleo-climate reconstruction from this study for northern Greenland. It clearly depicts the swings in 'BE' climate change from the warming of the MCA (medieval climate anomaly) to the cooling of the LIA (little ice age) and the extreme warming during the early 20th century (ETCW) from the 1920s to 1940s.
The study's author's make the following comments regarding the δ18O proxy:
"The δ18O values of the 20th century are comparable to the medieval period but are lower than that about AD 1420. …. The solar activity and internal Arctic climate dynamics are likely the main factors influencing the temperature in northern Greenland."
Each of these extremes shown are a result of natural internal/external forcings prior to the gigantic consumer/industrial influx of human CO2 emissions starting post-1950.
Per the abundance of climate empirical research, blaming Exxon and other fossil fuel entities for global warming is simply anti-scientific. Climate change, including that of the late 20th century, does not require a change in CO2 - a trace atmospheric gas -to happen.
