85% of the world population lives in the driest half of the planet.

Also, do read the blog post before you criticize it so obnoxiously. Most kids will probably not have a problem reading this. But do supply the link please.

People (as in climate scientists) are indeed suggesting that the Greenland and West Arctic ice sheets are at risk of significant melting, and that would produce a great deal of sea level rise. There is real meaning to the term “short” vs. “long” term here. If we build cities as we do now for the next century or two, and the sea level rises several feet by 200 years from now, the cities flood. If something unexpected happens and the sea level rises in half that time, the cities still flood.

Meanwhile, a very small amount of sea level rise is implicated in the flooding of the subways in New York City during Hurricane Sandy.

The problem is, we don’t have at present a good way to estimate the timing and nature of melting in the future. But we do know this: Avoiding extensive glacial melting requires curtailing the transfer of fossil carbon into the atmosphere. We’ve not done anything real to curtail that process. The timing and magnitude of future sea level rise is unknown. That we are at present doing virtually nothing to stop this is a fact.

Meanwhile, current sea levels seem to be enigmatically low, based on the palaeorecord. Think of sea level as a range that can occur in a given climatic setting. It is very likely that at present we are NOT at the high end of that range, and we may well be at the low end of that range. This is of concern.
