Climate models indicate it's not too late to avoid a 2°C average temperature increase by 2100 if our energy matrix and heavy industries (concrete, steel and fertilizers) move away from fossil fuels. This takes political conviction and government policy, which in turn requires correct understanding of the situation.

"it's too late" is a dangerous statement because it suggests actions no longer matter. And if no action is taken, several climate models project >4 °C average warming. The majority of the planet will be become uninhabitable at the current human density levels, with billions of people having to relocate and/or die.
