I almost promised I would not coment on this, but... Too many climate myths there to go on, space oddity (I count at least six), so why not take yourself over to
www.skepticalscience.com, a great Aussie site, and perhaps the best resource in the world to find out the actual scientific evidence that relates to your claims.
The hockey stick ... has been thoroughly
verified by science (see for example NAS, 2006), and appears in a range of records, not just tree rings, e.g.:

Notwithstanding that, the hockey stick does not underpin climate science, it's the physics of the atmosphere that does that, key observations being that less energy is escaping to space at wavelengths specific to greenhouse gases (e.g. Harries 2001), and more radiation is returning to Earth at those same specific wavelengths (e.g. Philipona 2004), a property of CO2 understood since Tyndall and a consequence predicted all the way since Arrhenius (he forecast back around the start of the 20th Century a 2-5C warming per doubling of atmospheric CO2).
And it's not just the physics of the atmosphere that leads us to the inescapable conclusions, as part of a huge consilience of consistent evidence ranging from palaeoclimate, physics, observations and models, there are particular fingerprints that lead us there in the pattern of warming:

As astronomers, we should all be extremely aware of the capability for certain elements and molecules to emit and absorb radiation at particular wavelengths. It's what makes most of astrophysics and our understanding of the Universe possible! It's why our UHC and OIII filters work so well on nebulae. Unfortunately for us, we are vastly increasing the concentration of one of the key scatterers of longwave radiation in our atmosphere. To pretend that either it is not happening or it won't be a major change means, like the great quote below by Dave2042, you have to pretend a vast amount of other, related, science does not work either.
