Why do so many of our leaders ignore the obvious? Is it not a fact that the climate has always changed? If the theory of anthropogenic global warming is correct, it cannot explain the massive climate changes which have occurred since the creation of the world. It can only explain a tiny sliver of that time.
But let us first assume that the theory correctly explains global warming, and secondly that the world is indeed warming. Let us then make a third assumption, that an international agreement significantly reducing emissions is achievable.
The Prime Minister and Senator Wong may think that will seal the deal. It will not. We must also assume that all major emitters will actually observe it. The fact is the number of countries which regard their international promises as binding is quite small.
If all nations become law abiding there is still a fifth and crucial premise before we can be secure against climate change.
This is that all of the other factors which have caused climate change over millions of years will thereafter be in a state of suspense.
Of course that fifth assumption just cannot be made. Even if we closed down every coal fired power station and stopped using oil.
