It's hard to pick which piece of misinformation is the biggest offender. For example, the prominent discussion of "Global Solar Minimum" on each page. This scare text flies in the face of the current thinking of the scientific community.

From Wikipedia:

"The current scientific consensus, most specifically that of the IPCC, is that solar variations only play a marginal role in driving global climate change,[79] since the measured magnitude of recent solar variation is much smaller than the forcing due to greenhouse gases.[88] Also, average solar activity in the 2010s was no higher than in the 1950s (see above), whereas average global temperatures had risen markedly over that period. Otherwise, the level of understanding of solar impacts on weather is low.[89]"

I guess if you think the IPCC is a cabal of Satan-worshipping Communists, then this brief analysis is suspect. But show me anywhere a reputable study that links solar variations to "drastic climatic and geophysical changes to our planet. These include increased galactic cosmic rays (GCRs), seismic activity, and volcanism" as IAF claims.

That is a well thought out response. The kind of response I was trying to illicit from the parent comment. The parent commentor had one quote and a one word response that did little to expand the discourse here.

The scare text you are referring to:

> grand solar minimum: a period during which solar activity diminishes, resulting in drastic climatic and geophysical changes to our planet. These include increased galactic cosmic rays (GCRs), seismic activity, and volcanism; the latter often results in a global reduction in temperatures (see "the year without a summer" -- and much more on the IAF wiki).

A piece from NASA(not technically a reputable study as you asked):

> But if such a Grand Solar Minimum occurred, how big of an effect might it have? In terms of climate forcing – a factor that could push the climate in a particular direction – solar scientists estimate it would be about -0.1 W/m2, the same impact of about three years of current carbon dioxide (CO2) concentration growth. https://climate.nasa.gov/blog/2953/there-is-no-impending-min...

I think three years of climate forcing offset is a "drastic climatic and geophysical change". However it would be difficult to link GCRs, seismic activity, and volcanism to it.

They were kind enough to give the server admins a reason for their termination!
