I was pleased to see the Unite Union make the case against the disastrous de industrialisation Mr Miliband’s policies are causing. I welcome Claire Couthino’s return from maternity leave as she takes on the argument that far from UK electricity being too dear because of the gas price, UK electricity is far dearer than gas thanks to extreme renewable policies. The mix of high guaranteed prices and substantial subsidy make new wind power very expensive. She rightly pointed out that recent guaranteed prices for renewable power from new wind farms are several times dearer than for gas generated electricity and for using gas as a primary fuel.
Some here want the main parties to dump the whole idea of climate change, challenging the science. In my two short books on the topic, “Build back green The electrifying shock of the green revolution” (2021) and “The $275 tn Green Revolution Will consumers buy it” (2024) I accepted the scientific consensus that CO 2 is a warming gas, and if nothing else changes more man made CO 2 leads to some overall warming.
I raised a number of questions about how the global temperatures are measured, why there were periods of global warming and cooling before mankind arrived and before the widespread human burning of fossil fuels, how accurate the climate models and forecasts are , whether sun intensity, water vapour presence and other important factors could offset or accelerate the impact of manmade CO 2 and other obvious issues. As many governments and universities continue to spend a lot of money and human resource on climate change studies, clearly they do not think the models are perfect or our knowledge complete. Some of you contribute to the scientific discussion. There is no sign that there is about to be a major change of scientific view held by the leading European and UK governments and the main universities.
I still do not intend to develop the debate about the pace, intensity or reality of global warming. By all means contribute to this debate if you have studied the models and the wider science. I wish to intensify the debate about UK net zero policies with a view to getting urgent change. To get that change we need the support of the many experts and people in power who do believe global warming is serious and brought on by current manmade CO 2.
One of the strongest reasons for change all in the debate should agree is the current UK net zero policies are wrong in their own terms. They increase world CO 2 with their manic pursuit of less CO 2 produced here but far more world CO 2 needed to produce all the imports we then need as we close down our own factories and oil fields. Imported LNG means 3 times as much CO 2 per unit burned than UK gas down a pipe from the North Sea.
They are wrong in saying the UK by closing down fossil fuel use more quickly will lead the rest of the world. Instead over the many years we have been leading the world in cutting our own CO 2 emissions manmade world CO 2 has continued to increase. There is no evidence that UK leadership has worked or will work all the time China and Germany wish to make things to sell to us with plenty of coal and gas in their mix of fuels.
They are even wrong over their proposed remedies for too much CO 2. Buying a new battery car may mean more world CO 2 not less when you take into account all the extra CO 2 produced by the mining for rare minerals, the manufacture of the batteries and the likely use pattern of the vehicle. Worse still much of the time in the UK when you come to charge the battery car there is no spare renewable electricity available so they need to burn more gas in a gas powered generator. The same can be true of a heat pump. On a very cold windless day in winter your heat pump will need more gas fired electricity to keep it running.
I will look in a later blog at the changes we urgently need in policy.
