I think this is another example of people taking scientific data and then making up crap that ultimately has nothing to do with the initially presented data.
Re. climate change. The evidence does not support the idea that our changing climate is driven by the Sun. Yes it is in part caused by changes in the Sun's radiation (we know that the Sun has various phases that it changes through) but that does not account for all the data collected on this topic. To suggest this idea as a reason for our changing climate/changing average temperatures shows that a lot of information is being ignored.
Re. Binary system. Missing the approach of a comet measuring approximately 20 metres in diameter is one thing. To suggest that we might be missing a red dwarf (the smallest estimations of which suggest a size of 34590 miles in diameter) is silly... There are unanswered questions related to the behaviour of the planets in the Solar System but, again, to suggest some of the above demonstrates a lack of knowledge of all the data available!
The bottom line is: Stop taking evidence in isolation to forward ideas that are destroyed in the light of all the available evidence...
