Re: Global Warming (Amaranth Rose)
No one is claiming that there are not some areas that are relatively low or that a rise of 1cm doesn’t translate into a distance of many cm or even meters inland. What was claimed was that islands with a high point of 81 meters above sea level would disappear due to the expected rise in sea level in the next 100 years. The best estimates are that the sea is rising a centimeter or so every year. In 100 years that translates to a meter or so, not 81 meters.
AR: The town I lived in was 40 miles inland, but only ten feet above sea level.
There are a few (very few) places like that in the world. This was acknowledged in the link provided in http://www.scienceagogo.com/message_board/messages/4621.shtml But the islands under discussion go up to 81 meters (260 feet) above sea level.
AR: That works out to about 4 miles across land for every foot rise in sea level, or a ratio of 1760:1. Roughly a mile for every three inches.
So if the ocean rises 1cm every year, it will travel inland 17.6 meters per year. That means that it would have only taken 300 years to go the 40 miles inland to where you lived. DA Morgan was claiming that the sea was rising 26 times farther in 1/3 the time. Seems like nonsense to me but I await the proof which now seems a vain hope.
