The climate alarmist definition of "settled science" (as if science is ever settled):
64 years of WRONG coming climate crisis predictions
40 years of WRONG climate computer game predictions
40 years of climate computer game predictions not getting more accurate
40 years of temperature revisions that almost always increase the slope of the global warming trend -- obviously not correcting random errors
100 years of no obvious acceleration of rising sea level using stable tide gauges
30 years of global warming with very little CO2 level change (1910 to 1940)
35 years of global cooling as CO2 levels rose (1940 to 1975)
45 years of pleasant, mild global warming (1975 to 2020), completely unlike the rapid, dangerous global warming predictions made during every one of those years.
The use of a single global average temperature, that not one person lives in, to disguise the fact that actual warming since the mid-1970s mainly affected colder regions, mainly during colder months and mainly at night.
Dismissing 4.5 billion years of climate change with natural causes -- in 1995 the IPCC declared natural causes of climate change were just "noise", with no proof that was true.
The United Nations IPCC allows politicians and climate activists to write the final draft of the Summary for Policymakers, where uncertainty from the back up science reports is deleted. The back-up science reports are released many months later, so the Summary and back-up can not be compared at the time when the Summary is released to the public. Most journalists just quote the Summary press release.
IPCC claiming a "95% confidence" in their predictions, which is a meaningless number, based on a consensus of personal opinions, not based on data, or past success with climate predictions. The 95% sounds scientific, but is not -- it is used for propaganda purposes. It has no relationship to the 95% often used with statistics.
Claims that +1.5 degrees warming from pre-industrial temperatures is a meaningful and dangerous number, with no scientific justification. Pre-industrial is only roughly defined with climate proxies, and people living at the time thought their climate was too cold, not an ideal climate.
Use of the propaganda term "climate emergency", with no scientific justification (after 64 years of wrong coming climate crisis predictions)
Use of the propaganda term "climate denier" to ridicule people who have NEVER denied the existence of climate change.
I suppose all of this adds up to "settled science" if you are a climate alarmist?
