The U.S. has caused more global warming than any other country. Here’s how the Earth will get its revenge.

[Washington Post] Last year, we learned what is probably the worst global warming news yet — that we may have irrevocably destabilized the massive ice sheet of West Antarctica, which contains the equivalent of nearly 11 feet of sea level rise. The rate of West Antarctic ice loss has been ominously increasing, and there are fears that if too much goes, the slow and long-term process of ice sheet disintegration could accelerate.
Humans have a hard time conceiving of the incredible scale of an ice sheet, so the consequences of such a change can be lost upon us. But in a new paper in the Proceedings of the Institution of Civil Engineers — Forensic Engineering, researchers Ted Scambos of the National Snow and Ice Data Center in Boulder, Colo., and John Abraham of the University of St. Thomas in St. Paul, Minn. – summarize what we now know about West Antarctica. That includes a finding that may serve as a wake-up call for Americans in particular.
Namely: If West Antarctica collapses entirely — a process that would likely play out over centuries, but that could substantially begin in this one – the expected 11 feet of sea level rise won’t just spread out evenly across the ocean. The United States will actually get a lot more sea level rise than many other parts of the world — possibly over 14 feet. Call it geophysical karma — we’re the nation most responsible for global warming and, at least in this particular case, we’ll get more of the consequences.
So what source of cosmic equity will mete out just deserts in this case? As it turns out — and the mechanisms will be explained in much more detail below — the answer is none other than Isaac Newton’s law of universal gravitation — which states that all objects in the universe attract one another in relation to their masses (and the distance between them).
