It sure has. Just since Friday.
There are some strange things about the whole theory.
There is widespread agreement (among the believers) that warming will result in rising sea levels and flooding of coastal areas. The rise of sea levels won’t be some non-measurable trivial amount, but enough to cover a 6 story building.
Here’s the problem. The world has has such warm temperatures before, and there is no evidence of sea levels being that high during those periods. In fact, there have been inhabited structures on the waterline in major cities all over the world for centuries, (Millennia in some cases). We have had piers and docks and coastal walls in cities like Venice, Rome, Athens, Alexandria, Egypt, NYC, Norfolk, just to name a few. In hundreds of years, none of those cities has shown any evidence of rising sea levels. Note: a city sinking into soft earth due to changes in silt deposits and inadequate foundations is NOT water levels rising. So New Orleans does NOT count.
