It's now past two years since SARS-CoV-2 (Covid-19) spread beyond China and became a pandemic.

From the outset, I've covered aspects of the pandemic on this website, beginning with Love in the time of Coronavirus back in March 2020, so the passing of the pandemic's second birthday seemed an appropriate time to review what we've learnt.

The positive news is that: Covid-19 has been far less deadly than the 1918-20 "Spanish Influenza' pandemic. 

This relative success in limiting the number of deaths this time round is entirely due to modern science.

Although historians disagree over the numbers, all agree that the Spanish Influenza pandemic killed a great number. The lowest estimate is 17 million worldwide, while another puts it at between 24.7 and 39.3 million. Most, including the National Museum of Australia and Wikipedia, tell us that over 50 million people died worldwide. This was when the population of the world was 1.9 billion, less than a quarter of that it is today. However, most historians do agree that that virus did not originate in Spain but first crossed to a human in the United States originally from a waterbird (it was H1N1), then possibly, via a pig. The earliest documented case was March 1918 in Kansas. It was carried into the trenches of the Great War by one or more American 'Doughboys', from whence it spread across the world as the war ended.  As Dorothy opined: 'Toto, I've a feeling we're not in Kansas anymore.'

In the early 20th century, vaccine development was by trial and error. Although bacteria could be seen using a powerful, optical-microscope, virions (virus particles) were invisible and could only be inferred to exist, like atoms 50 years ago. As a result, attempts to produce a vaccine in the 1920's targeted suspicious bacteria and were totally ineffective against the influenza, as were many attempted and folk-treatments - perhaps injecting disinfectant?  No, no one would be that stupid!

Masks and social distancing provided the only effective mitigation until natural (herd) immunity stopped the spread.

Unlike that, most deadly, to date, of all viruses, this virus certainly originated in China.

Taiwan

 

 

 

In May 2015 four of us, Craig and Sonia Wendy and I, bought a package deal: eleven days in Taiwan and Hong Kong - Wendy and I added two nights in China at the end.  We had previously travelled together with Craig and Sonia in China; Russia, India and South America and this seemed like a good place to do it again and to learn more about the region.

Taiwan is one of the Four Asian Tigers, along with Korea, Singapore and Hong Kong, achieving the fastest economic growth on the Planet during the past half century. Trying to understand that success was of equal interest with any ‘new sights’ we might encounter.

The Time Lord

 

 

 

For no apparent reason, the silver haired man ran from his companion, shook a tree branch, then ran back to continue their normal conversation. It was as if nothing had happened. The woman seemed to ignore his sudden departure and return.

Bruce had been stopped in peak hour traffic, in the leafy suburban street, and had noticed the couple walking towards him, engaged in good humoured argument or debate.  Unless this was some bizarre fit, as it seemed, the shaken tree branch must be to illustrate some point. But what could it be?

Just as the couple passed him, the lights up ahead changed and the traffic began to move again.

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:
