As an associate of Klaatu, stationed at our Earth-Observing, and listening post, at the Sea of Tranquility, our intercepts of communications inform us that, climate mitigation, as a function of government policy, has been continuously frustrated by a passive mechanism in the form of the 'Due Process' clause, of the 14th-Amendment to the U.S. Constitution, which has stood since 1885.
As a structural road block, baked into the 'American' system, there's a low probability that it can ever be rectified, and so, any grand gesture 'solution' to the Earth climate challenge would, by default, have to come from outside the 'beltway.'
That said, we people of the solar system have taken extreme comfort from any mistakes made in the people's interest, and activities that fell through the cracks by public servants, academia, the National Academy of Sciences, the National Laboratories, CIA, NRO, NSA, FBI, Military Intelligence, RAND Corporation, US Congress Special Committees, and the private sector, etc.; whom escaped the clutches of Washington lobbyists of a certain stripe.
While we reserve the option of activating Gort, we'll continue to monitor for the time being.
