Two heroes of the eco-loon-left, concoct conflicting, death-to-civilization schemes!----- The disagreement between two climate scientists that will decide our future

The disagreement between two climate scientists that will decide our future - Robert ChrisHugh Hunt
"Getting to net zero emissions by mid-century is conventionally understood as humanity’s best hope for keeping Earth’s surface temperature (already 1.2°C above its pre-industrial level) from increasing well beyond 1.5°C – potentially reaching a point at which it could cause widespread societal breakdown.
At least one prominent climate scientist, however, disagrees.
  • James Hansen of Columbia University in the US published a paper with colleagues in November which claims temperatures are set to rise further and faster than the predictions of the Intergovernmental Panel on Climate Change (IPCC). In his view, the 1.5°C target is dead. He also claims net zero is no longer sufficient to prevent warming of more than 2°C. To regain some control over Earth’s rising temperature, Hansen supports accelerating the retirement of fossil fuels, greater cooperation between major polluters that accommodates the needs of the developing world and, controversially, intervening in Earth’s “radiation balance” (the difference between incoming and outgoing light and heat) to cool the planet’s surface...
  • Michael Mann from the University of Pennsylvania in the US and another titan of climate science, spoke for many when he dismissed solar radiation management as “potentially very dangerous” and a “desperate action” motivated by the “fallacy … that large-scale warming will be substantially greater than (Mann's) current-generation models project”.
Their positions are irreconcilable. So who is right – Hansen or Mann? (Answer? Neither!)
