Is climate change real?
It is a stupid question. The climate has always changed and in ways that are vastly more sweeping than anything going on today. Less than 10,000 years ago, Britain and Ireland used to be connected to each other and to Europe. The North Sea used to be Doggerland. The Rhine, Seine and the Thames all used to flow into a river which is now the English Channel.
Britain was occupied by Paleolithic hunter gatherers before the last Ice Age. As a result of climate change, humans were completely driven out and retreated to southern Europe and only came back as the climate improved, the glaciers retreated and forests and the animals they hunted advanced back into northern Europe when the Holocene began around 10,000 BC.
The most spectacular example of climate change in Northern Europe though was when Doggerland sank under the North Sea, the English Channel was carved and Britain was transformed into an island in the Mesolithic era. The Storegga Slides off the coast of Norway unleashed one of the worst tsunamis in history.
