I'm no expert, but it seems to me that there's an objective, straightforward way to verify or falsify global warming. If true, global warming causes rising sea levels due to melting ice caps. Now there are countless structures in coastal towns and cities that have a high-water mark. The ocean at high tide stains the structure at that level. It's like a photograph of how high the the water rises at high tide. In addition, there are countless historical photos floating around which show the high-water mark in, say, the 19C. Presumably we only need a few clear-cut examples comparing the high-water mark in the 19C to the high-water mark in the 21C to establish if sea levels are, in fact, rising, or rising at an alarming rate.
Why are the coastal properties all packed with liberals who have invested in such wildly expensive real estate if it will be underwater soon?
ReplyDeleteSea levels have indeed varied in the past, it was much lower in the last ice age. So there is an intrinsic trade-off. You get more un-submerged land area but at the cost of uninhabitable ice masses at higher latitudes. Ice ages are pretty miserable things, another one would chop down civilization to a fraction of its current size.
It seems to me sea levels might rise a bit. I don't see evidence that it is running away on a catastrophic trajectory right now.
In particular, why did Al Gore sink (pun intended) his profits into a seaside property?
