In the northern hemisphere at least. We’ve hit the equinox, when the day and night lengths are the same. Cold, arrives, now. Unless we get some late summer heat. There’s been hailstorm in the North East of England and heavy rain in Scotland. Across the Northern hemisphere there have been hurricanes in North America and Typhoons in Asia.
The other side of the world is experiencing Spring. The South is getting warmer as the Earth starts to tip its south Pole towards the sun. The tilt of the Earth means that we have seasons. If the world was at 90° day and night would be equal across the whole world. 12 hours of light, 12 hours of dark. No glorious late evenings in summer or long dark nights in winter. What an interesting world we live on.
And it’s not flat!
