(38,192 posts)The rate of acceleration of extreme global heating, as represented by the concentration of the dangerous fossil fuel waste carbon dioxide, has been rising about as fast as hype about so called "renewable energy," on which trillions of dollars have been squandered in the last 10 years for no result with respect to the use of fossil fuels:

Trends in Atmospheric Carbon Dioxide (CO2)
The popular enthusiasm for so called "renewable energy" began soaking hundreds of billions of dollars per year in the early 21st century.
Nevertheless, one can show that the rise in concentrations is roughly quadratic.
That should tell people something, but regrettably it doesn't.
The reactionary enthusiasm for so called "renewable energy" - which was largely abandoned in the 19th century for a reason - was never about attacking fossil fuels. It was always about attacking nuclear energy, a form of energy put to work by some of the finest minds of the 20th century and surely the last best hope of saving that which has not yet been destroyed, and perhaps even restoring that which can be restored.
So called "renewable energy" depends on access to fossil fuels, and has had no effect on their increasing utilization. The land and mass intensity - and carbon intensity - of this stuff is appalling.
