Twelve thousand years ago sea levels around Africa rose much faster than today
It’s another totally solid, non-controversial paper that will never be mentioned in the media or by 50 shades of climate experts.
In extraordinary detail, Vecchi et al look at 347 datapoints up and down the west coast of Africa and find that, like everywhere else, sea levels were a blockbuster 125m lower at the depths of the ice age 25,000 years ago. Then seas rose in rapid bursts as the vast Laurentide and Eurasian ice sheets melted, until they finally stopped rising 8,000 years ago. It must have been twelve thousand years of mayhem for corals, mangroves and beach-side cave-dwellers.
In the northern Gulf of Guinea seas were recorded as rising at up to 25 mm per year about 12,000 years ago — eight times faster than anything we see today. And given the difficulty of knowing sea levels 15,000 years ago, there were probably many short episodes of faster shifts that got washed away, never to be recorded.
All our panic about the current crisis of a pitiful 3mm-a-year rise allegedly “due to man-made CO2” pales to nothing compared to what Monster Nature […]
