Scientists have discovered plant and insect remains under a two-mile-deep (three km) ice core extracted from the centre of Greenland, providing the clearest proof yet that nearly all of this vast territory was green within the past million years, when atmospheric CO2 levels were much lower than today.
The important message here is that natural climate change has caused huge changes and so it could do so again. The vast cost of trying to achieve net zero is likely to be futile. Instead we should adapt to the climate as it evolves.
