If the Light truly wanted to elevate Humanity's place in the stars, I find it extremely hard to believe they would wish to cause nuclear winter in Happy Harbor, Rhode Island.

With that said, there is one small change other than Neutron's personal circumstances. Before Bart departed, there was ash in the air, implying nuclear devastation. After he left, the ash is gone; it's just snow.

Now, I'm not sure if there wasn't any nuclear holocaust in the new future though. After all, it's mid-February, and no longer supposed to snow.
