During much of the Holocene Climatic Optimum -- roughly in the period of 5,500 to 9,500 years ago -- when the Earth was warmer than now, sea levels were something like two meters higher than today.

Lower ocean salinity, but somehow the Earth managed to survive.

The expectation is that this time climate change will be unusually rapid and many species and habitats will not be able to change quickly enough.

Even worse than the start and the end of the Younger Dryas?

Well, in a thousand years check-in here again and we can compare notes.

In the Younger Dryas, the temperature changes of something like 10 F are thought to have happened in a decade or so.

The real danger to us will be when the Holocene ends and we begin the next hundred thousand years of glaciation. When that happens, two things are likely:
1) Starvation and death by starvation will become very common.
2) Massive wars will likely be fought for the Earth's dwindling resources.

Like it or not, a warmer planet is a more productive planet. It can feed more people. A colder planet, on the other hand, inevitably means death. In contrast to the warmer period prior, the lesser cooling of The Little Ice Age led to starvation becoming a very real problem.

As for now and the future warming, the sky is not falling.

We'll see. Anything that causes massive extinctions sounds bad to me.

What mass extinctions has this caused?
