This video was posted on Peak Prosperity.  It’s over three years old now, but it’s an excellent talk that may clarify a lot of questions for DTM readers.  Enjoy…..

The idea that humans are responsible for most of the warming is a furphy. Humans are responsible for all of the warming plus some. (Notice how William Ruddiman’s work is becoming mainstream)

but who would tax us, condemn our lifestyle all the while being creepy hypocrites?
And let’s not start with the guilt tripping by the alarmists ..

One question. I though there was about 80 meters of sea level rise if all the ice melted and then add 20 to 30 meters of sea level rise from isostatic rebound and the gravity effect of the glaciers. Dan Britt talks of sea levels being more than 200 meters higher during the cretaceous, backed up by well accepted science. Is all that difference due to the Himalayan uplift?

The figure I’ve seen is 65m if ALL the landed ice melted….

And yes to your 2nd question.

Been looking around and the figures do vary. Hard to know who includes what, but we do have the direct effect of the melted ice, rebound, gravity of the ice sheets and circulation changes. And that is the static ocean, not accounting for storm surges, increased wave height and wave ramping.

Academic really, not even the most pessimistic see anything like that in our life time, or the lifetime of our children. However there are many much more pessimistic than the IPCC

..funny how 45 million centuries of climate, climate history, and warming & cooling have not yet ended life on the planet ..
And who set tax rates and carbon trading all those millions of years?

It came close a few times, and each time, it took MILLIONS of years for diversity to claw back……

Generally, biodiversity recovers 5 to 10 million years after the extinction event. In the most severe mass extinctions it may take 15 to 30 million years. The worst event, the Permian–Triassic extinction event, devastated life on earth and is estimated to have killed off over 90% of species. https://en.wikipedia.org/wiki/Extinction_event

This is also the very first time ONE species existing on earth, us, is responsible for such an extinction event. In the past, such events were entirely beyond the control of any species living at the time, so silly comments about Carbon taxes are just that, silly…
