Alarmists pushing the natural climate-change denial propaganda have been eviscerated by the overwhelming force of recent empirical evidence - surprise, surprise, the cascade of evidence has even forced the extreme-left NY Times and The Economist to admit their previous beliefs reporting of disastrous global warming myths was without scientific merit

Before pursuing the myth-busting, a small explanation may help: this chart depicts the length of slight/flat global temperature trends, without the usual monthly datapoint variability plotted. In addition, the incessant growth of atmospheric CO2 levels is plotted.
Now on to those busted "global warming" myths. From this chart of empirical evidence, we can safely conclude the following:
#1. CO2 is not a global temperature thermostat that would allow politicians/bureaucrats
to 'dial-in' a desired Earth temperature, as claimed by IPCC official alarmists
and anti-CO2 activists - simply put, the climate is not very "sensitive" to trace atmospheric levels of CO2
#2. CO2 is not causing any measurable global warming - depending on the empirical dataset, global temperatures have been flat (ie, slightly declining) over the last 8 to 16 years
#3. CO2 is not causing rapid, accelerating, unequivocal, irrefutable, incontrovertible, undeniable nor irreversible global warming - from the empirical evidence, we know these traits are literally non-existent
#4. CO2 is not causing "runaway" nor "tipping point" climate change due to rapid global warming, which, as previously listed, is completely AWOL over recent years
#5. CO2 is not even causing the much ballyhooed, hoped-for, at a minimum, tiny "statistically significant" warming. Indeed, for time spans now approaching two decades statistically significant warming is nowhere to be found - in fact, the RSS lower atmosphere satellite measurements show no statistically significant warming over the last 23 years
Conclusion: The "consensus" anthropogenic global warming (AGW), and especially the "catastrophic" version (CAGW), has proven to be not much more than failed exaggerated myths and urban fearmongering legends that are scientifically indefensible at this point.

With those anti-CO2, climate change alarmist myths eviscerated by the obvious scientific facts, one should not forget, though: a repeat of the modern non-dangerous global warming could re-start at any time and last for several years, or longer; widely accepted physics suggests that rising CO2 levels do have a modest warming impact on global temperatures (up to a possible 1.5 degree climate sensitivity for each doubling of CO2); and, natural climate change will continue regardless of the trace levels of CO2 - common sense science indicates that going from 4 to 6 parts per million of atmospheric CO2 has very little climate impact, per the real-world physics of a logarithmic temperature response.
Regarding that last mention of 'natural climate change,' it should be remembered that the anti-CO2, global warming alarmists deny that natural climate change is the primary, dominant driver of global temperature swings and climate oscillations.
Through a combination of yet barely identified and poorly understood earthly/solar/cosmic natural forces, via the newest research it is now becoming more appreciated by a growing legion of scientists that the climate responds in a non-linear and chaotic manner that simply overwhelms any CO2 trace gas influence during the short, medium and long-terms.
The IPCC et al. alarmists religiously deny the dominance of natural climate forces yet continue to mindlessly blame CO2 despite all objective evidence that at best, it has a weak, minor role in the world of climate outcomes.
Additional evidence that CO2 does not cause (and has not) rapid, accelerating and dangerous global warming.
