In 1995, 2,500 of the world’s top climate experts announced that east coast beaches were doomed by the year 2020, due to sea level rise.
At the most likely rate of rise, some experts say, most of the beaches on the East Coast of the United States would be gone in 25 years.
East coast beaches are sinking due to post-glacial rebound, and the rate hasn’t changed. It isn’t clear how an increase of 0.0001 mole fraction CO2 over the past century would affect geologic processes in the mantle.
As always, climate scientists had/have no clue what they were talking about. But with each new failure, their certainty increases. Now at 99%.
