Yeah you forget something. There where predictions made for late 90s, 2000 and after by these people. NONE of them came through. In fact, clowns like Al Gore predict sea rise to wipe out coasts in a couple of years and at the same time buy houses next to that sea.
It is largely a scam, not that the climate isn't changing, it always changes. The impact we have on it has been played to tax us to death by people who have a carbon footprint of a typical country.
