That seems to be a rather daft way of displaying the statistics. A graph would have been easier to read. And, IMO, 100 years isn’t enough data to get a decent trend going. 10,000 years might be useful. Remember, it’s not that long ago the Thames used to freeze regularly, and just over 1000 years ago England had a far warmer climate than we had now, and 1500 years ago there was a cool, wet period…..

Imagine that happening now. Maybe no planes flying for 3 years for a start, if it was a volcano…… Just a thought……
Once we’ve burnt all the fossil fuels in a few years, it’ll start righting itself. 🙂
