Well, the protest is located at the root of the problem, that being the WH and its ignorant, arrogant, and stupid resident. The US was the leader in CO2 emissions until China overtook it in recent years. But, China's population is over four times larger, so its per capita CO2 emissions is much lower than the US. The US government needs to take the lead on climate change. It will take trillions of dollars over decades and only governments have that kind of money. But, politicians like Trump will not act unless enough people (voters) wake up to the danger and push for action. Then Trump will realize that his reelection chances may be reduced if he does not act.

And it won't require extreme and unrealistic goals like AOC has been pushing. Such actions will totally collapse the global economy and society. We just need to start by retrofitting electric power plants (coal and gas only) with carbon capture modifications. Yes, it will cost a lot, but not as much as the consequences of inaction. This is doable people, from a technological standpoint. We just need to get the politicians to act, and Greta is doing her level best to do just that. Let's help her out!
