Keeping and open mind I hope, it seems to me that the evidence of human introduced climate change, riding on top of any natural climate variations, is a fact. That said, and despite the amount of Australia’s atmospheric pollution being largely irrelevant in a world sense, everyone, (not just the prime polluters China and the USA), needs to join with the world all over in playing our part in the control of what global warming effects that we can.
The vast majority of climate science indicates that in the next decade, we are likely approaching a so called ‘tipping point’, where, by the end of this century, atmospheric heating effects will ‘run away’, out of our control, and lead to a vastly different and much less hospitable world to live in for those who follow us.
It appears that we will need world wide political pressure, by every voter, everywhere, to effect the necessary changes we need, and rapidly reduce our reliance on oil, gas and coal, if we are to have any chance of keeping our world largely as it is today.
A friend of Greypath has just released a heartfelt video on the subject which you might care to have a look at and circulate elsewhere if you wish.. https://www.youtube.com/watch?v=6Unnnnc9F70
