Ancient Orkney Islanders reveal an interesting insight into climate change.
I was pursuing my inner desire to be history detective with regards to Orkney. The Orkney Islanders are interesting because they marked the zenith of henge building technology, in some ways more impressive than Stonehenge. Archaeologists have discovered a neolithic village that is going to take decades to uncover, and I am intensely wanting to know what the DNA studies of ancient Orkney skeletons will reveal.
In about 2500 BCE the majority of the henge builders of Orkney abandoned the island, and this was about the time when Stonehenge was being built. Immediately I am looking for the reason why the people of Orkney abandoned ship – climate change or invasion?
I did not pick up any evidence of an invasion of Orkney, but I did of climate change, this was when I picked up a pattern. Generally, since the last ice age the weather has been moving towards a warmer period, but with somewhat random cycles of mini shifts in climate. In 2500 BCE a few interesting patterns emerge:
- Glaciers increase.
- It gets colder.
- It gets drier.
In Orkney in about 2500 BCE it was so cold the people went south to the warmer areas of the South of England. This was the period that the Sahara dried up to become desert today, and the glaciers were expanding.
Today, the reverse is going on:
- Glaciers are decreasing.
- It is getting warmer.
- More rain.
I ran a check to see if the south of the world was different in the north, and the pattern remains the same. I then did a check on the Sahara Desert, for in this pattern there should be more rainfall in the Sahara. Eureka! There is more rain in the Sahara Desert, for that desert is starting to go green again.
I am no scientist, but I know a pattern when I see one. I am deeply skeptical about the scaremongering claims of global warming scientists, who claim that this climate change is man-made. Nope, this is a natural cycle, and no amount of what we do is going to make a difference in stopping this cycle from proceeding.
What is of concern is that with shifts of the climate there is in history a mass migration of people: which brings widespread warfare; paradigm shifts like the change from the bronze to iron age (another story); collapse of civilisations; displacements of people. In 2500 BCE there was said to be 30 million human beings in the world, now there are 7000 million people, and these people can’t migrate so well. The future is going to be messy.
