David Spratt (Breakthrough Institute), speaks 2014 at the Royal Melbourne Institute of Technology about climate change, myths, and realities. His latest repo...
For the current level, 410 ppm CO2, from the paleoclimate record, the earth was “4-6 C higher in temperature, and sea levels were 25-40 meters higher.”
This is the baseline -- what we might expect in terms of changes -- if we were to somehow miraculously completely stop emitting carbon right now (8/18). This is what is coming, at a minimum, regardless of how aggressively we attack climate change right now.
The world is already reshaped in drastic and catastrophic ways.
Spratt explains climate models are prized over paleoclimate data, even though the climate models are incomplete and have been vastly underestimating observed changes.
He argues this is because climate science has been co-opted by politics.
