Paul Beckwith weighs in behind geoengineering
Can climate change cause human extinction?
Can climate change cause human extinction?
No
sane person can expect indefinite exponential growth on a finite
planet. Are we close to a breaking point? Can we slam on the brakes?
Is NTHE (near-term human extinction) possible? How long is near-term
anyway? Decades, centuries, or millennia? That depends on who you
ask...
Can global sea-level rise 7 meters by 2070?
Global
sea levels rose about 2 mm per year over the last century, but this
rate increased to 3.4 mm/yr over the last decade. As Greenland and
Antarctic ice cap melt rates accelerate, they open up the likely
scenario of a global sea level rise of 7 meters (21 feet) by 2070.
Cooling the Arctic with geoengineering
The
idea of geoengineering sends shivers through the spines of many
people. In this video I explain why it is absolutely necessary to
cool the Arctic to keep the feedbacks in check while we slash GHG
emissions.
I am no longer surprised at the weak understanding scientist actually have regarding human survival on a warming planet. Beckwith doesn't seem to understand the food situation at all. Lovelock has become deranged regarding human survival, temperatures, nuclear energy and more. These are not men who have actually come to grips on what it means for just 4C temperature increases, let alone 8C - 10C. It's rather sad and tragic that there is so little practical understanding from these climate advocates.
