In California it is 2000 years. As in the worst draught in 2000 years.
“When the scientists talk about records, how far back do these records go?
“
And sometimes (often) the record highs are in a couple os hundredths of a degree. Not even out of the margin of error!
Got a greenie friend to do a search on his computer;
What % of the atmospere is Nitrogen? “Wow! More than I thought!”
What % of the atmosphere is Oxygen? “Wow! Less than I thought!
What % of the atmosphere is Carbon Dioxide? “Wow! That’s all” ?”
Hopefully his wheels are turning!
