Solar activity also has an influence on earth's geomagnetic storms (aa) which should become less prominent now.

Why does it only go to 2007?

Old data, his graph only goes towards the end of solar cycle 23, we are currently going into the end of solar cycle 24. Also OP is incorrect, the Modern Maximum began in 1900, not in 1600.

It's not easy to see what is sarcasm and what isn't regarding climate change. I've seen and heard people say stuff like what you wrote in your post while being completely serious.

I see. I'm not offended that you thought I was being serious and gave a good and simple summary.

But my point on the lowered sun activity would decelerate the global warming was a serious curiosity. Because it seems both would counterbalance for sometime, but of course that if we keep increasing greenhouse effect when the sun goes to another high it will be quite problematic. 

As far as we can model, it will have less impact on global warming than human greenhouse gas emissions already have, but if we enter a new grand solar minimum, yes it will to some degree negate climate change and global warming.

Ok. What exactly does that mean? Are we all going to DIE DIE DIE?!

That user was banned from this site years ago I believe. 

 

So after human cause the largest mass extinction since the comet or Astroid killed the dinosaurs we are all about to die from cold?

No, that user was banned from this site years ago. Im sure of it.

Waiting to see how much spin this will have in the hand of politicians of all types.

I assume it was taken from a publication made in 2007 or 2008. The correlation will probably still be constant.

I have not specified a beginning of the Modern Maximum (but I would put it at around 1940).

So would you please clarify what you meant by "It seems that after 400 years we might be entering a new phase of diminished solar activity"? I don't quite understand why you said 400 years instead of 80 years.
