Our Once And Future Oceans: Taking Lessons From Earth's Past : NPR
Paleontologists have spent a lot of time trying to understand a time, more than 50 million years ago, when the planet was much hotter than it is today. They're finding that the news isn't all bad when you take the long view.

"Looking in the geologic past, and also, of course, using models to forecast the future, is a little bit like looking into a house through dirty windows," [Dick Norris] says. "You don't get all the details of what's going on there, but you get sort of the gist."

"If we wait, even a fairly short period of time, like 80 years, to deal with greenhouse gases and the global [climate] change problem, then we end up with these really remarkably long ecological impacts on Earth, where it takes 20,000 years to sort of start to readjust to something we would be familiar with now," he says.

Nah, that is an old line from around 1970. Then it went like this:
"If we don't put one more drop of pollution into Lake Erie, it will take 10,000 years for it to clean up itself."
So, what happened after we passed the Clean Water Act?
Pollution entering the lake was reduced to 25%. TEN years later the results:
The lake had cleaned up and had 90% cleaner water.
So, the "one drop" thing was bull.
And the 10,000 year thing was a joke.
