It would, in my humble opinion, have been much more useful to do something with that $1.4M that would make it unnecessary for future generations to worry about global warming.
Needless to say, in the typically brutal entrepreneurial fashion (the one that is responsible for much of the muck we’re in at the moment) it’s much ‘cooler’ to look like you’re doing something about it, than to actually help cool the climate down.
It would also have been much simpler.
