Many will post commentaries declaring what the weather will do next century like it's a certainty!
Reality.
We have magnetic field records in rocks 4Gyr old, we have thousands of years of detailed human records about Earth's magnetic fields and fluctuations, we can measure these things with instruments more sensitive and accurate than any thermometer. Yet we can't predict where the magnetic north pole will be next year beyond a general trend in direction and speed, it's behaviour tomorrow is a mystery! It's finely detailed movement is chaotic!
It’s relatively easy to interpret the past (my caper) but predicting what’s going to happen in the future is another kettle of fish altogether.
A significant unknown is whether the Anthropocene impacts will negate the forces that would normally cause a change from inter-glacial to glacial.
Then there’s asteroid strike :o
“Why don’t you knock it off with them negative waves? Why don’t you dig how beautiful it is out here? Why don’t you say something righteous and hopeful for a change?” Oddball
