Re: Nature: Approaching a state shift in Earth's biosphere

Over the past few days Australia has been treated to anomalous weather conditions, that no doubt, will be reflected in various comment as peak weather conditions or through bifurcation into climate change.
No matter what, recorded climatic events and their epitomal like recordings for the past thousand years or so are still the backstop for current day events i.e. freak weather including snow, hits Australian southern states and southern Queensland, (a sub tropical region of Australia)... worst weather seen in 75 years.
Are those recordings now letters of marque against a backdrop of 10, 15, 30 thousand years, eons for climate change? Does the current 50-100 years poor weather reflect climate change any more than polarity reversals were/are indicative of mass extinctions for instance? Statistically yellowstone should blow, in Colombia the recent increase in seismic activity under Sotarà an "extict" volcano suggests this geologic relic is not what it was touted to be.
If the above is so, how long were the periods involved and what were their actual precursors; vulcanism, toe-picking? At least this subject, a state shift in Earth's biosphere is "only" approachinga state shift in Earth's biosphere, how long until we reach the proposal the unification of state shift in Earth's biosphere, climate change and magnetic pole reversal are dependent on each event?
Dohboi suggests the "The next five, and certainly ten, years will see nearly the entire globe go into a dramatically different state." what we don't appear to have here is the empirical data to support links to catastrophic global change perhaps with the scrutiny of geopaleontological evidence, but that answer will only satisfy a few as an explanation.
Perhaps our civilisation will be dug up as a radiological anaomoly.
Nah, bad theory, it was a natural event; No civilisation could be that stupid.
