There is the following science consensus: the anthropogenic global warming hypothesis has never been empirically validated outside the confines of a computer simulation.
Essentially, across many parts of the world, the lack of warming and the lack of unusual warming - i.e. unprecedented, exceptional warming - confirms that the fear of human CO2-driven catastrophic warming is likely very misplaced.
Similar to the recent scientific findings of unexceptional modern warming for many parts of the world, such as in the U.S., across Antarctica, and multiple other regions of the world, scientists in China have analyzed a 350+ year climate record and found modern warming is not unusual versus the warming of earlier periods in the record.
"In general, the average length of cold periods was shorter than that of warm periods. The cold period of 1869–1877 was the longest and coldest cool period had a mean of 17.63°C. The longest warm period extended from 1655 to 1668, and the warmest period in AD 1719–1730 had a mean of 20.37°C. However, we should point out that the rapid warming during the 20th century was not especially obvious in our reconstructed RLST."
The scientists also determined that human CO2 was not a factor driving the warming and cooling analyzed.
"Accompanied by significant peaks at 60.2 and 73 years, the continuously periodicities around 49–114 years in our regional temperature reconstruction might tentatively be related to PDO, Atlantic Multidecadal Oscillation...as well as solar activity...The AMO was an important driver of multidecadal variations in summer climate not only in North America and western Europebut also in the East Asia...The 60.2-year peak associated with AMO demonstrated that multidecadal variations in late summer temperature in the NWSP NWSP [northwestern Sichuan Plateau, China ] might be controlled by AMO."
This 2016 study from China adds to the enormous amount of empirical evidence demonstrating that an all encompassing modern "global" warming from human CO2 does not exist.
The scientific evidence is unequivocal: There exist huge regional climate swaths of the globe that have mildly warmed in an unexceptional manner during the modern industrial/consumer era; and there exist multiple large areas that even lack any regional climate-significant modern warming whatsoever.
