This is probably a bit simplistic but we have found so many lost cities over the last century or so and we know they have been destroyed or buried by weather changes. They thrived before the age of technology and carbon emissions.
Quote:Many cities have been destroyed by natural disasters and rebuilt, sometimes repeatedly. But in other cases the destruction has been so complete that the sites were abandoned completely. Classic examples include the Roman cities of Pompeii and Herculaneum, buried with many of their inhabitants under a thick layer of volcanic ash after an eruption of Vesuvius.
A lesser known example is Akrotiri, on the island of Thera, where in 1967, under a blanket of ash, the remains of a Minoan city were discovered. The volcanic explosion on Thera was immense, and had disastrous effects on the Minoan civilization. It has been suggested that this disaster was the inspiration that Plato used for the story of Atlantis.
Less dramatic examples of the destruction of cities by natural forces are those where the coastline has eroded away. Cities which have sunk into the sea include the one-time centre of the English wool-trade, at Dunwich, England, and the city of Rungholt in Germany which sank into the North Sea during a massive storm surge in 1362.

I live about a km from the sea - yet I am always finding shells surfacing in my garden. A mountainous area about 12 km inland from where I live not long ago discovered ancient fish fossils at the top of the mountains indicating that the area was once covered in water. How do we explain these buried cities and marine fossils millions of years old?
Mantra,
The reason we find shells inland are varied. Most landmasses are constantly shifting .
It's perfectly true that conditions in the Geological past were warmer, and that atmospheric CO2 levels were higher than today. Nobody disputes that.
It's also true that there was practically no ice cover at the poles for extended periods in Geological history.
In terms of today's crisis, this is all cold comfort. The main problem, as I've repeated time and time again, is the fact that we're heading into a major human catastrophe as a result of the fact that unlike these past episodes, we actually have people and cities on Earth. It can be simply bad, or it can be catastrophic, depending on what action the world's governments take.
By the way, you can also find marine fossils in the alps and Mount Everest. To explain mountain building or orogeny in a single post is not possible. This Wikipedia article seems accurate enough at first glance.
