"From the OP's link:

>>"The Sun is in a changed state. It is brighter than it was a few hundred years ago and this brightening started relatively recently - in the last 100 to 150 years."

To the best of my understanding, the Max Planck institute is not a collection of woo-woo's.. (but it's amusing that people who say the same thing here are labeled thus)"



Yes, it's a collection of learned scientists.

Dr Postspam along with a collection of silly government paid shills that lurk and post on GLP all claim no visible change in the colour and brightness of the Sun. Yet, most of us see otherwise.
All of these sky-watchers (debunkers) lining up on the same side of this issue (the Sun hasn't changed) speaks volumes of their intended presence here.

And we are to believe them before an institute of scientists that study the Sun. Doff!
