A lively and well-presented video.

Takeaway point: variation in solar activity is extremely unlikely to be connected with the global warming and consequent climate change of past decades. That's down to greenhouse gases. Which means us.

Can someone link to the average global temperature for the specific time period of 1310 to 1350 (anno domini)? ...and a record of sun activity for just that same time period would be helpful as well, thank you!

You could.

Return and report. Pay a research assistant if you can't manage to do it yourself.

It is more cost effective to simply ask for that information from those who claim to have it.

So why don't you do just that?

I did, but you have yet to respond.

(For subs ...)

Yes. Without the sun, it would be damn friggin’ cold outside.

In other news, fatness is caused by food. People have nothing to do with it. : )

The Sun has been a very boring object for astrophotography lately unless you use Hydrogen-Alpha filters. Haven't seen a decent sunspot in years. That's good for having fewer coronal discharges, which is good for humans who want their ionosphere operating normally. :razz:

I have never claimed to possess the specific information subgenius asked for, which was:

....the average global temperature for the specific time period of 1310 to 1350 (anno domini)? ...and a record of sun activity for just that same time period ....

I don't deny that (as some posters may have noticed) I have extensive search and access rights for a very wide range of scholarly and scientific publications. But if subgenius wants that information about forty years in the 14th century (which I don't currently have before me, and have never claimed to have before me), I am under no obligation to do the work for him,
