What is that "qualification" you are asking for? What kind of qualitifaction does it take, to make a statement as simple as "you can't lose what you don't have" AND have it accepted?
What we have here is a situation that is the exact same thing as a politician claiming that crime is on the rise: Just look at the amount of money that has been stolen in each of the last 30 years. It has been rising consistently, it is now 3 times larger. Crime is three times worse!
Not so says Joe Public pointing out that people now also earn 3 times as much money and are carrying around 3 times as money. There is 3 times as much money around to steal. So you would expect the same level of thievery to net 3 times as much money.
But of course, what is clearly a fearmongering politician in the case I described here, is suddenly perfectly plausible as soon as the climate crowd moves in. You, sirs and madams, are disgusting.
