Are we delaying action on climate change because we are racist?

Maybe I phrased the problem wrong, it might not be directly about racism, but the racism i am referring to is “structual racism”, it seems the regions most vulnerable to climate change is Africa and the Artic; the people living in those regions are not the regular consumer , voter, car driver, and money makers. If climate change actually directly affects north Americans , would we care more?

After all, Africa has been dying for how long already? since we were born?

PS: I mean, people building a freaking wall between Mexico and the U.S to prevent illegals from coming, and maybe we should just admit that climate change will produce a bunch of non white climate refugees and there is no economic or political incentive to help them.
