Climate activists in Australia and abroad are spruiking their latest alarmist report - released at the peak of the northern hemisphere summer - claiming we are on the cusp of 'Hothouse Earth' and that sea levels could rise as much as 60 metres.
The Conservative Party policy is to put Australia first - getting out of the Paris climate pact and the futile attempts to participate in CO2 emissions reduction targets that are not binding on major economies and emitters.
The Australian National University's Professor Will Steffen published a statement saying "the real concern is these tipping elements can act like a row of dominoes - once one is pushed over, it pushes Earth toward another. It may be very difficult or impossible to stop the whole row of dominoes from tumbling over."
CNN quotes one of the co-authors of the 'Trajectories of the Earth System in the Anthropocene' paper by the American Proceedings of the National Academy of Sciences, Katherine Richardson of the University of Copenhagen, saying:
"The implications are that if we can't stop it we're in a hell of a mess. Our societies could not continue the way they are now with an average temperature increase of 4°C to 5°C (and) 10 to 60 meter sea level rises. It would simply be unbearable for our society."
By contrast, Professor Ian Plimer wrote in The Australian newspaper on Tuesday that:
Climate policy is underpinned by two fallacies. The first is that human emissions of carbon dioxide drive global warming. The second is that future climate can be predicted from computer models.
For the past 4567 million years, the sun and the Earth’s orbit have driven climate change cycles. In the past, the atmospheric carbon dioxide content has been orders of magnitude higher than now, yet there were ice ages.
Plimer further notes that:
The Paris accord is non-binding. This is recognised by the major carbon dioxide emitters such as China, India and the US, which don’t comply. No EU state has met its target. Why should Australia be the only country out of step and aim for an impossible, bankrupting reduction of 26 per cent or more of our 2005 carbon dioxide emissions?
As the whole of New South Wales becomes drought-declared for the first time in decades this week, self-described 'global Greens ambassador' and former leader Christine Milne criticised the National Farmers Federation in her tweets for failing to have a climate change policy in response to the drought. NSW Greens MP Jeremy Buckingham tweeted today "any discussion of drought which ignores climate change does our farmers a massive disservice". Current Greens leader Richard DiNatale previously tweeted "the best form of drought assistance is to tackle climate change."
Conservative Party founder and leader, Senator Cory Bernardi, explained recently why he called for Australia to never join the Paris climate pact.
