Talking Topics is a list of issues that come up on the web or in books, the latest of which we will discuss at our meeting on the date given.
The article needs no further comment.
2016’s year in charts shows that clean energy revolution is unstoppable.
China’s latest five-year energy budget invests $360 billion in renewable generation alone by 2020. Beijing calculates the resulting “employment will be more than 13 million people.”
The UK government should take note.
Some of the comments under this article make one despair but the move to renewables is unstoppable.
The UK should be doing even better in this chart from the article:
And we thought it would just get a bit pleasantly warmer and the plants would have more CO2 food to grow better.
The fast-melting ice in the Arctic and an increase in snowfalls in Siberia, both the result of global warming, are changing winter weather patterns over east China, scientists found. Periods of stagnant air are becoming more common, trapping pollution and leading to the build up of extreme levels of toxic air.
The work is the latest to show that changes in the rapidly warming Arctic are already leading to severe impacts for hundreds of millions of people across North America, Europe and Asia. The US has also seen a rise in episodes of stagnant air, which may be leading to higher air pollution there.
Maybe we are heading for Humexit.
“This is the biggest challenge we have at the moment as a company … the fact that societal acceptance of the energy system as we have it is just disappearing.”
A moment of hope.
This staid presentation is bad news for us.
The bad news is in the “and accelerating”. We do central heating via hot water in pipes and radiators because the thermal capacity of water, its ability to store heat energy, is large. For example, for the same volume of iron and water, water will hold more energy if both are heated by the same increase in temperature.
The warming rate from 1992 is almost twice as great as the warming rate from 1960. Moreover, it is only since about 1990 that the warming has penetrated to depths below about 700 meters.
We are locked into this for several thousand years now.
Opinion is changing.
About 60% of people in the UK, France, Germany, and Norway think we are seeing the effect of global warming in climate change now.
Subsidising renewable energy with public money was popular, with 70% support in the UK and Germany, 75% in France, and 87% in Norway.
Yet the UK government gives renewables a bashing.
And, to add insult to injury –
Bizarrely, state schools with solar panels will be forced to pay, while private schools will remain exempt.
I think the views here are relevant for considering how we deal with climate change:
This is well worth reading.
The observations are under heading:
People Make Rational Decisions
People Follow Procedures
Governance Should Treat Everyone Equally
We Can Have more Parties / Elect Better Representatives
We Know What Decisions To Make
Laws Should Be Carefully Deliberated and Made to Last

Experts can still be effective: Scientists can win the war on science — by speaking out
There are still many simple improvements to be made for our basic needs. This cheered me a lot.
Gan and his team have claimed that their prototype produces as much as three times more potable water as comparable solar stills, or about 4.2 cups an hour under sunny conditions.
Our climate models are better than the deniers make out:
Now, 30 years later, the models have become much more detailed with fine-grained observed data to fit.
Expect investment in fossil fuels to drop as people warm to the thought of suing companies that extract and sell them takes off with climate change:
But not the kind we want.
It is increasingly clear that the heaviest burden of climate change is falling on the planet’s oceans, which absorb more than 30% of the carbon produced on land.
Scientists have long predicted ocean deoxygenation due to climate change, but confirmation on this global scale, and at deep sea level, is concerning them. Last year, Matthew Long, an oceanographer at the National Center for Atmospheric Research in Colorado, predicted that oxygen loss would become evident “across large regions of the oceans” between 2030 and 2040. Reacting to the German findings, Long said it was “alarming to see this signal begin to emerge clearly in the observational data”, while Roberts said, “We now have a measurable change which is attributable to global warming.”
