The science behind net zero

I have long made many important arguments against the policies the U.K. is following in the name of net zero. I have shown how closing down our own energy using industries only to import from elsewhere adds to world CO 2. I have pointed out that plugging an EV or heat pump into the grid may just lead to us burning more gas in a gas power station which creates more CO 2. I have shown how we will lose any well paid jobs and tax revenue as we rush to close down our domestic oil and gas production, close our steel works, undermine our refineries, petrochemical works, ceramics, aluminium, glass and other heavy energy using industries. I did not vote for the climate change targets as there was no proper costing or feasibility study.

Some of you want to make a case that far from being settled the science does not prove that serious global warming is happening from manmade CO 2. So this is your opportunity to summarise the case for that view or for the government counter. It would be useful if both sides could deal with the following points made in the debate when and where it is allowed.

1. Given there were periods of global warming and global cooling before mankind lived here, what caused those big changes? Could those forces change  the climate again? Will they reinforce warming or will some cause cooling?
2. What allowance is made for natural CO 2, water vapour, solar intensity, volcanic activity and other causes of warming and cooling?
3. What tests have been performed on models to back test them against temperature data, and to check them at future dates against predictions?
4. Why do some models and most official commentary concentrate on manmade CO 2 to the exclusion of all the factors that did cause climate change before mankind arrived, and in history before the coal based Industrial Revolution and the population explosion got under way?

5. Why when seeking to combat manmade CO 2 on a national basis do they not recommend the U.K. stops growing its population as that is a major cause of extra  manmade CO 2?

6. What is the total CO 2 impact of making battery electric cars including extracting the rare earths and metals through to disposing of the battery?
