In 2005 I calculated that in Australia, due to our use of coal to generate electricity, electric cars had a higher carbon footprint than conventional cars. 

There's been a lot of water under the bridge since then and now (April 2019) many are promoting electric cars as environmentally friendly, so I thought it was worth a revisit. 

 

 

Recently, an increasing number of friends and acquaintances has told me that Climate Change is a myth.  

Obviously they are talking about 'Anthropogenic Global Warming', not disclaiming actual changes to the climate.  

We don't need climate scientists to tell us that the climate changes. Our own experience is sufficient to be quite sure of that. 

During my lifetime the climate has been anything but constant.  Else what is drought relief about?  And the ski seasons have definitely been variable. 

In the longer term we all have to rely on others. For example on scientists who have themselves examined ice cores or tree rings or sea level records or other physical evidence that can be dated. 

So I'm prepared to believe the scientists who have determined sea levels showing that fourteen or fifteen thousand years ago a hypothetical Australian could walk from Tasmania to New Guinea or an Irishman all the way to Java.

This rise has not stopped.  During my lifetime the average sea level in Sydney Harbour has risen by nearly a foot, in keeping with long term trends.  More water in the Harbour on average obviously has temperature and therefore microclimate implications.  There are thousands of well documented examples of changes like this that have climate impacts.

But like the tides there is great variability that masks the underlying trends.   For example 2014 was a record warm year in Sydney.  But in mid 2015 we were going through the longest cold spell in 45 years.  It snowed in Queensland!

- a Recent Wall Street Journal article

 

 

A recent wall street journal article 'The Last Carbon Taxer' has 'gone viral' and is now making the email rounds  click here...  to see a copy on this site.  The following comments are also interesting; reflecting both sides of the present debate in Australia.

As the subject article points out, contrary to present assertions, a domestic carbon tax in Australia will neither do much to reduce the carbon impact on world climate, if implemented, nor make a significant contribution, if not implemented.

It's finally announced, Australia will have a carbon tax of $23 per tonne of CO2 emitted.  This is said to be the highest such tax in the world but it will be limited to 'about 500' of the biggest emitters.  The Government says that it can't reveal which  these are to the public because commercial privacy laws prevent it from naming them. 

Some companies have already 'gone public' and it is clear that prominent among them are the major thermal power generators and perhaps airlines.  Some like BlueScope Steel (previously BHP Steel) will be granted a grace period before the tax comes into effect. In this case it is publicly announced that the company has been granted a two year grace period with possible extensions, limited to its core (iron and steelmaking) emissions.

 

 

One night of at the end of March in 1979 we went to a party in Queens.  Brenda, my first wife, is an artist and was painting and studying in New York.  Our friends included many of the younger artists working in New York at the time.  That day it had just been announced that there was a possible meltdown at a nuclear reactor at a place called a Three Mile Island , near Harrisburg Pennsylvania. 

I was amazed that some people at the party were excitedly imagining that the scenario in the just released film ‘The China Syndrome’  was about to be realised; and thousands of people would be killed.

Morocco

 

 

In August 2008 we visited Morocco; before going to Spain and Portugal.  We flew into Marrakesh from Malta and then used the train via Casablanca to Fez; before train-travelling further north to Tangiers.

Through the Looking Glass

 

 

 

 

 

I'm seeing on TV senior politicians, including the Liberal PM and involved Labor Victorians (bi-partisan), gathering in Morwell in Victoria to announce that jobs in the Latrobe Valley have been saved by a Japanese consortium that will build a pilot plant to convert brown coal to hydrogen. Read Here...

I had to pinch myself to check that our screen had not somehow turned itself into Lewis Carroll's looking glass and sucked me through to the other side.

Fans of the Reverend Dodgson's (Lewis Carroll's) work will recall some 'weird shit' in Wonderland like: Alice growing and shrinking; a disembodied cat coming and going; and babies turning into pigs.  But these adventures are put into the shade by Alice's subsequent experiences: Through the Looking-Glass

Hydrogen from coal (carbon) - really?  Surely they mean hydrogen from water.

A modern fairytale - in a Parallel Universe

 

I've dusted off this little satirical parable that I wrote in response to the The Garnaut Climate Change Review (2008).  It's not entirely fair but then satire never is.

 


 

 

In a parallel universe, in 1920† Sidney, the place where Sydney is in ours, had need of a harbour crossing.

An engineer, Dr Roadfield, was engaged to look at the practicalities; including the geology and geography and required property resumptions, in the context of contemporary technical options. 

After considering the options he reported that most advanced countries solve the harbour crossing problem with a bridge.  He proposed that they make the decision to have a bridge; call for tenders for an engineering design; raise the finance; and build it.  We'll call it the 'Sidney Harbour Bridge' he said; then less modestly: 'and the new crossing will be called the Roadfield Highway'.
