fail and the end result is that trillions of dollars will be wasted that we could have used to adjust to global warming?
In 1883, Krakatoa erupted, spewing volcanic ash and gas into the stratosphere, making clouds more reflective and cooling the entire planet by roughly 1° C that year. In 2018, the UN reported that human activity has already raised Earth’s temperature by 1°, and if we don’t do something drastic soon, the results will be catastrophic.
The optimal solution is staring us in the face, of course; reduce carbon emissions. Unfortunately this optimal solution is politically untenable and extremely expensive. A decade ago McKinsey estimated it would cost $1 trillion just to halve the growth of carbon emissions … in India alone. That’s still less than the cost of doing nothing — estimated at $20 trillion by Nature, which doesn’t include its toll on human lives — but it’s a cost which seems to make the necessary political decisions impossible.
