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 - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
