Homework done

I said yesterday that I thought Malcolm Turnbull’s defiant press conference speech last night is one of his best. Here is what he said.

I appreciated his allusion to that well-known leftist plotter against capitalism Margaret Thatcher. Here (I quote from my entry of 2007 Miranda asks a question or two on climate change) is an example of her subversion in 1990:

…the threat to our world comes not only from tyrants and their tanks. It can be more insidious though less visible. The danger of global warming is as yet unseen, but real enough for us to make changes and sacrifices, so that we do not live at the expense of future generations.

Our ability to come together to stop or limit damage to the world’s environment will be perhaps the greatest test of how far we can act as a world community. No-one should under-estimate the imagination that will be required, nor the scientific effort, nor the unprecedented co-operation we shall have to show. We shall need statesmanship of a rare order…

In recent years, we have been playing with the conditions of the life we know on the surface of our planet. We have cared too little for our seas, our forests and our land. We have treated the air and the oceans like a dustbin. We have come to realise that man’s activities and numbers threaten to upset the biological balance which we have taken for granted and on which human life depends.

We must remember our duty to Nature before it is too late. That duty is constant. It is never completed. It lives on as we breathe. It endures as we eat and sleep, work and rest, as we are born and as we pass away. The duty to Nature will remain long after our own endeavours have brought peace to the Middle East. It will weigh on our shoulders for as long as we wish to dwell on a living and thriving planet, and hand it on to our children and theirs.

I want to pay tribute to the important work which the United Nations has done to advance our understanding of climate change, and in particular the risks of global warming. Dr. Tolba and Professor Obasi deserve our particular thanks for their far-sighted initiative in establishing the Intergovernmental Panel on Climate Change.

The IPCC report is a remarkable achievement. It is almost as difficult to get a large number of distinguished scientists to agree, as it is to get agreement from a group of politicians. As a scientist who became a politician, I am perhaps particularly qualified to make that observation! I know both worlds.

Of course, much more research is needed. We don’t yet know all the answers…

But the need for more research should not be an excuse for delaying much needed action now. There is already a clear case for precautionary action at an international level. The IPCC tells us that we can’t repair the effects of past behaviour on our atmosphere as quickly and as easily as we might cleanse a stream or river. It will take, for example, until the second half of the next century, until the old age of my grandson, to repair the damage to the ozone layer above the Antarctic. And some of the gases we are adding to the global heat trap will endure in the Earth’s atmosphere for just as long.

The IPCC tells us that, on present trends, the earth will warm up faster than at any time since the last ice age. Weather patterns could change so that what is now wet would become dry, and what is now dry would become wet. Rising seas could threaten the livelihood of that substantial part of the world’s population which lives on or near coasts. The character and behaviour of plants would change, some for the better, some for worse. Some species of animals and plants would migrate to different zones or disappear for ever. Forests would die or move. And deserts would advance as green fields retreated.

Many of the precautionary actions that we need to take would be sensible in any event…

On recent claims of dishonesty in the IPCC I commend on one side Miranda Devine and on the other George Monbiot. The links are in yesterday’s entry. Monbiot answers the charge effectively. **

You should also note that I can sympathise at least with Greg Sheridan’s dilemma (see yesterday’s entry) when he says: “I do not know whether the science that says we’re all doomed if we don’t de-carbonise the economy is true. Neither does anyone else.” Sympathise but not entirely agree, as I do think the odds are that the IPCC is more than likely right. Yes, we are talking about something which by definition cannot certain until after it has happened, and I probably won’t be around to see it. But Margaret Thatcher’s last line makes as much sense now as it did in 1990 when a great deal less was known on the subject.

I don’t think the government has done a good enough job of explaining the issues at stake, or what their ETS is actually meant to achieve. That is a shame. (New Zealand passed its own ETS the day before yesterday. Did anyone notice?) On the other hand there is much clear material on the Department of Climate Change website.

My opinions aren’t worth a lot. Lord May of Oxford is much better informed.

And he is a Sydney High Old Boy… 🙂

** And a SBHS ex-teacher (Geography) and friend is even more persuasive! See Thoughts on Climate Change after the CRU Hacking.

…Troubled as I am by the academic jealousy I’m far more troubled by the timing of this breach of the CRU and by the character of the political beings who’ve been so vocal about it. So it was with some interest that I encountered this fascinating article The SwiftHack (ClimateGate) Scandal: What You Need to Know. The article makes the following points:

* The scientific consensus on climate change remains strong.
* The impacts of catastrophic climate change continue to rear their ugly head.
* Hacking into private computer files is illegal.
* All of the emails were taken out of context.
* The story is being pushed by far-right conspiracy theorists.
* Scientists are human beings and they talk frankly amongst themselves.

Clearly this hack of a research organisation is an interestingly timed diversion….
