I checked the calculations myself and this does appear to be accurate…
I’m not one of the “we have 12 years to save the planet” doomsayers. But it does feel like we are approaching an inflection point. We will survive; but our options for how we will survive are narrowing rapidly.
Saturn is losing its rings. The shepherd moons are keeping it together but the ice is slowing raining down on the planet and not being replenished. So be sure to take a look some times in the next … well, 100 million years.
