At first, we were mere “skeptics.” Then we became “flat-Earthers.” “Denier”, with its Holocaust-denial implications soon followed. But none of these perjoratives worked for the climate alarmists.
Now the alarmists have re-christened skeptics as “birther-equivalents.”
Well they can call us whatever names they like, but to paraphrase Galileo:
Etiam CO2 facticius non tepidus exitialis
(Still manmade CO2 doesn’t cause catastrophic warming).
