I clicked expecting to see that this Congressional luminary was just trying to make a joke with his lunatic idea. But his saturnine demeanor occluded that possibility
Maybe he's been indulging in too much moonshine.
As I noted, he doesn't think we can alter the orbit of the planet or the moon, he is an idiot for thinking orbit shifts (not really happening) and the uptick in solar flares (not happening over the last several years if I'm not mistaken) are the cause of climate change. Therefore, anything we try to do would be worthless.
The Republican is mocking the person testifying, saying we are powerless, unless
you can change the orbit of the Earth and Moon.
