Our recent trip to Central Australia involved a long walk around a rock and some even longer contemplative drives.

I found myself wondering if there is more or less 'life' out here than there is in the more obviously verdant countryside to the north south east or west. For example: might microbes be more abundant here?  The flies are certainly doing well. Yet probably not.

This led me to recall James Lovelock's Gaia Hypothesis that gave we readers of New Scientist something to think about back in 1975, long before climate change was a matter of general public concern.

 

 

 

 

We can sum this up in a word:

Hydrogen

According to 'Scotty from Marketing', and his mate 'Twiggy' Forrest, hydrogen is the, newly discovered panacea, to all our environmental woes:
 

The Hon Scott Morrison MP - Prime Minister of Australia

"Australia is on the pathway to net zero. Our goal is to get there as soon as we possibly can, through technology that enables and transforms our industries, not taxes that eliminate them and the jobs and livelihoods they support and create, especially in our regions.

For Australia, it is not a question of if or even by when for net zero, but importantly how.

That is why we are investing in priority new technology solutions, through our Technology Investment Roadmap initiative.

We are investing around $20 billion to achieve ambitious goals that will bring the cost of clean hydrogen, green steel, energy storage and carbon capture to commercial parity. We expect this to leverage more than $80 billion in investment in the decade ahead.

In Australia our ambition is to produce the cheapest clean hydrogen in the world, at $2 per kilogram Australian.

Mr President, in the United States you have the Silicon Valley. Here in Australia we are creating our own ‘Hydrogen Valleys’. Where we will transform our transport industries, our mining and resource sectors, our manufacturing, our fuel and energy production.

In Australia our journey to net zero is being led by world class pioneering Australian companies like Fortescue, led by Dr Andrew Forrest..."

emergency
/uh'merrjuhnsee, ee-/.
noun, plural emergencies.
1. an unforeseen occurrence; a sudden and urgent occasion for action.

 

 

Recent calls for action on climate change have taken to declaring that we are facing a 'Climate Emergency'.

This concerns me on a couple of levels.

The first seems obvious. There's nothing unforseen or sudden about our present predicament. 

My second concern is that 'emergency' implies something short lived.  It gives the impression that by 'fire fighting against carbon dioxide' or revolutionary action against governments, or commuters, activists can resolve the climate crisis and go back to 'normal' - whatever that is. Would it not be better to press for considered, incremental changes that might avoid the catastrophic collapse of civilisation and our collective 'human project' or at least give it a few more years sometime in the future?

Back in 1990, concluding my paper: Issues Arising from the Greenhouse Hypothesis I wrote:

We need to focus on the possible.

An appropriate response is to ensure that resource and transport efficiency is optimised and energy waste is reduced. Another is to explore less polluting energy sources. This needs to be explored more critically. Each so-called green power option should be carefully analysed for whole of life energy and greenhouse gas production, against the benchmark of present technology, before going beyond the demonstration or experimental stage.

Much more important are the cultural and technological changes needed to minimise World overpopulation. We desperately need to remove the socio-economic drivers to larger families, young motherhood and excessive personal consumption (from resource inefficiencies to long journeys to work).

Climate change may be inevitable. We should be working to climate “harden” the production of food, ensure that public infrastructure (roads, bridges, dams, hospitals, utilities and so) on are designed to accommodate change and that the places people live are not excessively vulnerable to drought, flood or storm. [I didn't mention fire]

Only by solving these problems will we have any hope of finding solutions to the other pressures human expansion is imposing on the planet. It is time to start looking for creative answers for NSW and Australia  now.

 

 

 

  

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. 

 

 

 

Back in 2015 a number of friends and acquaintances told me that Climate Change is a myth.

Half a decade on and some still hold that view.  So here I've republished a slightly longer version of the same article.

Obviously the doubters are talking about 'Anthropogenic Global Warming', not disclaiming actual changes to the climate.  For those of us of a 'certain age' our own experience is sufficient to be quite sure of that the climate is continuously changing. During our lifetimes the climate has been anything but constant.  Else what is drought and flood relief about?  And the ski seasons have definitely been variable.

Travel

Darwin after Europe

 

 

On our return from Europe we spent a few days in Darwin and its surrounds.  We had a strong sense of re-engagement with Australia and found ourselves saying things like: 'isn't this nice'.

We were also able to catch up with some of our extended family. 

Julia's sister Anneke was there, working on the forthcoming Darwin Festival.  Wendy's cousin Gary and his partner Son live on an off-grid property, collecting their own water and solar electricity, about 120 km out of town. 

We went to the Mindl markets with Anneke and her friend Chris; and drove out to see Gary, in our hire-car, who showed us around Dundee Beach in his more robust vehicle. Son demonstrated her excellent cooking skills.

Nepal Earthquake

 

The World is shocked by the growing death toll, that has now passed 5,000 as a result of the recent earthquake in Nepal.

The epicentre was close to Pokhara the country's second largest city with a population just over a quarter of a million.  Just how many of the deaths occurred there is not yet clear.
