Yep, the "Man made" bit is the entire justification

Every single politcal and lobbyist action on "Climate Change" to date has been based on the premise that human action is the major factor.

In some cases (Ozone layer depletion) this was backed by genuine evidence.

Since then, it's based on unsupportable projections. Yes, unsupportable.

"2 deg C rise by X, 4 deg C rise by Y unless we change our habits." That's been the political and lobbyist message for the last decade or so, and it's bollocks, because we simply don't know.

We have no idea whatsoever what the "with action/without action" results will be, so we're chasing dragons.
