Since time immemorial, our climate has been and will always be changing. Patrick Moore explains why “climate change,” far from being a recent human-caused disaster, is, for a myriad of complex reasons, a fact of life on Planet Earth.
In just the past 2000 years:
- the Roman Warm Period (warmer than today)
- the cooler Dark Ages
- the Medieval Warm period
- the Little Ice Age (which drove the Vikings out of Greenland)
- and a gradual 300-year warming.
That's a lot of changes. And of course, none were caused by humans.
