David Attenborough hit the headlines yet again in 15 May 2009 with an opinion piece in New Scientist. This is a quotation:

 

‘He has become a patron of the Optimum Population Trust, a think tank on population growth and environment with a scary website showing the global population as it grows. "For the past 20 years I've never had any doubt that the source of the Earth's ills is overpopulation. I can't go on saying this sort of thing and then fail to put my head above the parapet."

 

There are nearly three times as many people on the planet as when Attenborough started making television programmes in the 1950s - a fact that has convinced him that if we don't find a solution to our population problems, nature will:
"Other horrible factors will come along and fix it, like mass starvation."

 

Bob Hawke said something similar on the program Elders with Andrew Denton:

 

 

 

Climate

 

I originally wrote the paper, Issues Arising from the Greenhouse Hypothesis, in 1990 and do not see a need to revise it substantially.  Some of the science is better defined and there have been some minor changes in some of the projections; but otherwise little has changed.

In the Introduction to the 2006 update to that paper I wrote:

Climate change has wide ranging implications...  ranging from its impacts on agriculture (through drought, floods, water availability, land degradation and carbon credits) mining (by limiting markets for coal and minerals processing) manufacturing and transport (through energy costs) to property damage resulting from storms.

The issues are complex, ranging from disputes about the impact of human activities on global warming, to arguments about what should be done and the consequences of the various actions proposed.

South Korea & China

South Korea

 

 

I hadn't written up our trip to South Korea (in March 2016) but Google Pictures gratuitously put an album together from my Cloud library so I was motivated to add a few words and put it up on my Website.  Normally I would use selected images to illustrate observations about a place visited.  This is the other way about, with a lot of images that I may not have otherwise chosen.  It requires you to go to the link below if you want to see pictures. You may find some of the images interesting and want to by-pass others quickly. Your choice. In addition to the album, Google generated a short movie in an 8mm style - complete with dust flecks. You can see this by clicking the last frame, at the bottom of the album.

A few days in Seoul were followed by travels around the country, helpfully illustrated in the album by Google generated maps: a picture is worth a thousand words; ending back in Seoul before spending a few days in China on the way home to OZ.

The Chimera of Clean Coal

The Chimera - also known as carbon capture and storage (CCS) or Carbon Sequestration

Whenever the prospect of increased carbon consumption is debated someone is sure to hold out the imminent availability of Clean Coal Technology; always just a few years away. 

I have discussed this at length in the article Carbon Sequestration (Carbon Capture and Storage) on this website. 

In that detailed analysis I dismissed CCS as a realistic solution to reducing carbon dioxide emissions for the following reasons:
