Over each of the past several centuries, including the last one, sea levels rose by about 7 inches (18 cm).
Accordingly, neither the overall warming trend or sea level rise began with the fossil-burning Industrial Revolution… nor have they changed in any detectable way due to human influences. And we can’t even really know that the second follows the first. Sea levels rose during the Little Ice Age from about 1400-1859 AD… a period which was considerably colder than now.
Unlike floating sea ice (the Artic) which doesn’t influence sea level when it melts, the West Antarctic Ice Sheet is part of the land mass. When it melts, it adds to sea level just as melting glaciers do. The end of the last Ice Age 18,000 years ago caused the sea level to rise by a huge amount…about 400 feet. This change happened rapidly at first, caused primarily by the melting of huge ice sheets covering North America and Eurasian land masses which disappeared about 8000-5000 years ago.
The West Antarctic Ice sheet began to melt at that time also, but at a much slower rate, and that melting continues today. We might expect this melting to continue until it is gone in another 7,000 years or so… or until the next Ice Age, whichever comes first.

Today's Featured Article - Timing Your Magneto Ignition Tractor - by Chris Pratt. If you have done major engine work or restored your tractor, chances are you removed the magneto and spark plug wires and eventually reached the point where you had to put it all back together and make it run. On our first cosmetic restoration, not having a manual, we carefully marked the wires, taped the magneto in the position it came off, and were careful not to turn the engine over while we had these components off. We thought we could get by with this since the engine ran perfectly and would not need any internal work. After the cleanup and painting was done, we began reassembly and finally came to t
