Ok, so who IS the 1% ?

I've heard anyone who makes over $500,000 yearly, and I've heard anyone with net worth more than 9 million.
Both of these seem a bit extreme to me... what is the real figure?

implying that "if we don't drastically reduce carbon emissions, shit will hit the fan" is unfalsifiable
implying you even know what falsifiable means
implying it's not common for scientists to change disciplines
