It’s a step in the right direction. But I don’t see anything of substance coming from this. The U.S. has become a Corporate Oligarchy. Apple has enough money and desire to fight this through appeals and lobbying. Pay attention to who they lobby and make sure they are voted out of office. It’s going to take a long time to correct what has happened over the last 20 or so years. It will require slow gradual change.
I assume it has to do with the fact that along the equator it’s typically warmer and the equator runs through the northern part of South America. So if temperatures go up they’ll go up there first and head north south respectively. I don’t think they meant Souther Hemisphere as much as they mean Southern Mexico / South America.
