Oceans Rising AND Land Rising, too!
Yet there are even longer-term impacts that most people might not notice. For instance, if you live in Canada, the northern U.S. or parts of Europe, the earth beneath your feet is rising. The reason is, more or less, because of the weather.
Not weather like yesterday's rain, or last week's wind. This phenomenon was caused by snows that piled up to create great ice sheets that covered the land in the last Ice Age. OK, it was a lot of snow, over a long period of time, so it's probably better described as climate than just weather.
I thought warmer was climate and cooler was weather.
I'm in the Global Cooling camp, myself. North America is tilting upward because of the weight of all that snow in northern Canada. New Orleans is gonna be 11 feet above where she sits now in only 32,000 years. Fix that problem and it'll be Global Stable for the next 72,000 years. At that point the continent will start sinking again because of the additional weight caused by overpopulation. We should probably start planning right now for the sake of our remote descendants. Of course, that'll take quite a bit of money...
The Earth's surface rises about 1 millimeter a month in Canada and about the same amount over the course of a year in the U.S., she said. For a place like Canada's Hudson Bay, the changes would be apparent over a person's lifetime, she said.
That's a long time to stand in one place...
"If you have a dock that you built, the ocean appears to be going down," Damiani said.
Up down, up down, warmer, cooler. I'm so confused. Ya suppose it might all average out?
When researchers calculate the rise of the world's oceans because of the current melting of glaciers and ice sheets, they need to keep the rebound rates in mind, according to a December 2012 NOAA report.
But when the glaciers melt, then the land will rise, compensating for the loss of seashore, right?
The motion is tracked using global positioning satellites and is used in making sure maps stay accurate, Damiani said.
This is the same GPS used to show that sea levels vary by as much as 150 feet, due to local variations in gravity, right?
