“Let’s get this on the table right away, without mincing words. With regard to the climate crisis, yes, it’s time to panic. We are in deep trouble.” @BulletinAtomic does not mince words in their special report on solar geoengineering (1/x) tandfonline.com/doi/full/10.10…
“To halt global warming, the emission of carbon dioxide into the atmosphere needs to be brought all the way to zero. The longer it takes to do so, the hotter the world will get. Lack of progress towards decarbonization has created justifiable panic about the climate crisis.”
“Barring technological breakthroughs allowing for the active removal of massive amounts of CO2 from the atmosphere, the cumulative carbon we emit will determine the climate our descendants will have to cope with for at least the next 10,000 years, and probably much longer.”
“And because of the mismatch between the millennial persistence time of CO2 and the sub-decadal persistence of stratospheric particles, solar geo can never safely play more than a very minor role in the portfolio of solutions. There is simply no substitute for decarbonization.”
“With continued 2.5% compound growth, we hit our trillion-ton 2C limit in under 27 years. If the trend continues beyond that time, the dark magic of exponential growth brings our planet to two trillion tons in 50 years (4C ) and three trillion tons (6C) just 86 years from now.”
“Just 2 degrees Celsius of warming would have been bad enough; 4 degrees Celsius of global warming would be ‘cataclysmic.’” And 6C?
“The question is not whether to panic, but how to respond constructively to the entirely justifiable anxiety about the climate disruption we are bringing upon ourselves.” (X/x)
