1. The Earth retains warmth under atmospheric gases: nitrogen, oxygen, water vapour, argon and carbon dioxide.

2. Increasing carbon dioxide to 0.0415% has not increased heat retention significantly.

3. Earth’s oceans, atmosphere and land receive heat energy from solar radiation, human combustion, forest fires, volcanoes, geothermal activity and from exothermic chemical reactions.

4. Earth is cooled by radiation into space, especially at night and in winter.

5. Most energy captured, extracted, wasted and used on Earth ends up as low temperature heat in the oceans, land and atmosphere.

6. When more energy is used than is radiated into space, heat accumulates causing warming.

7. To reduce warming globally, all humans must waste and use less energy.

8. Energy supplied, from all sources, is unable to be renewed and heats the oceans, land, atmosphere and space.

9. To reduce global warming, humans must reduce energy consumption using the most thermally efficient technologies.

My novel Animal Farm 2 explains these viewpoints.


Interaction between people used to be face to face, by physical correspondence or by phone. Then began social media with online messaging, trading and dating,

COVID19 has disrupted physical interaction, with people in quarantine, self-isolated, socially distanced, stranded overseas, unable to travel, nor able to attend school or university, nor get together with family and friends, not able to obtain goods or services, nor go to work.

Online platforms like Skype and Zoom are substituting interaction using the internet, computers, pads and phones to convey audio and visual messages, with sharing of documents, photos, videos and whiteboards.

My intent here is to presage online revolution. A paradigm shift is a fundamental change in approach or underlying assumptions. Substitution online is proceeding apace and in some situations change could be permanent.

Some online meetings are so successful that travelling to meetings could end. Efficacy of the substitution could depend on the culture of interaction, its traditions, ability to adapt and needs for personal physical involvement.

Online interaction is radically transforming retailing, education and health services. Organisations going online could employ people in different roles, to code response algorithms and to serve customers from premises which could be altered or relocated. Consumers too could have different involvement, working at home or at centres, where online interaction can be complemented by personal interaction, for example, in education.

Curtailment of physical interaction by COVID19 is generating internet traffic. An online revolution could have benefits for some people and problems for others. Reduced commuting could free up time, empty roads and buses, congesting parks and public spaces. With home working online, dwelling in an outer suburb may not be a disadvantage.

Because employees could be redeployed, retrained or even lose their jobs, going online may be resisted. Technological and social changes, made temporarily for COVID19 without a masterplan, allow responses case by case that could shift familiar paradigms.
