Light a fire in a house and it gets warm. And we have been lighting fires in our global house** at an accelerating pace for a few hundred years.

The Earth's climate has swung with the Earth's orbit as it precesses, goes oval at times, as the volcanoes spew big time, or the sun decides on coronal mass ejections and as meteorites collide, with a list of other things homo: Sapiens/ Neaderthals / Denisovans et al have not contributed to. And meteorites are a damn sight faster than what modern humans are doing. And one did for most of the species that had found a far too comfortable a niche.

But then history has to repeat itself, no-one is listening.

**where the chimney, huh?
