No, they're yellow...
Also Waaaay back in 1913 before cars (for the most part) The hottest temp ever recorded on earth was 134° in Death Valley. It has not been that hat there again yet. This "warming" thing sure does work slow!
I've had many conversations with my 85yo mother who remembers one or two summers & winters that were extreme but, not that different to todays extremes...
"Global warming" indicates a condition where,
overall, global conditions are changing; the most common part is the melting of the polar caps, causing ocean levels to rise; this is not unheard of, nor has it never occurred before, the earth has been undergoing changes for ever (has anyone ever hears of the ice age?) & will
continue to change forever, not because we are changing it but, just because that's what happens...
So, global warming? Maybe. Climate change? Not to any measurable extent...
Just my 2 cents...
