I did think there was something wrong with the reporting in general recently - seems to be quite a few years been mentioned as the change of the cycle, yet it's been far too frequent to actually be the case for a normal one.
I actually did a project on my last year of my BSc looking at sunspot cycles in a lake... from 385 million years ago.
Wow. How do you get the sunspot details from that? I actually did a project on my last year of my BSc looking at sunspot cycles in a lake... from 385 million years ago.
Edit. I know there have been a few mass extinction events over time, was it related to one of them? (not checked when they were).

Just done a week on the Norfolk Broads. It was more of an expedition.
Fugging cold and constant fog.
Not been in fog that doesn't lift by mid morning before. This descended on the Tuesday and was still so thick today that we gave up at lunch time and came home.

"no such thing as the wrong weather, just the wrong clothing"
He was wrong though.

A very old and common saying. "no such thing as the wrong weather, just the wrong clothing"

Nothing like a good walk on a windy, rainy day if you’re wearing the appropriate gear.

See if I can remember it correctly! A section of rock was taken with laminations (thin layers a few mm thick mostly) of rocks that come from a lake bed. What I did was use a very fine drill bit to drill out a bit of rock powder from each of these layers, which was then put in a mini-furnace and burned. This produced a reading of carbon etc, which gave an idea on how much life there was living at the time in that layer. Edit.

This showed that (likely) each dark and light pair of laminations was from 1 year - winter was the lighter band, which had less life (less sunlight etc), and in addition more rain washed more sand into the lake in winter, diluting the carbon from life. With this "confirmed" then you could also compare the amount of life living in the lake each summer and how it changed by comparing the carbon reading between each dark layer. By doing this you could see there was an approximate 11 year cyclicity in the carbon, so suggesting it was sunspots then.
This paper was done a little after (not by me), which uses the thicknesses of layers from a very quick scan, which seems to confirm it in a slightly different method.

Essex , this morning , right now , the sky is blue & a large bright yellow orb is sending down comforting warmth . What's happening ? 
Set out for bicycle ride at 7.30. quite cool temps. Got home 2 hours later and it was blazing sunshine. I warmed up well. Just stopped in time as I would have been overdressed if I carried on.
