Mr Opinionated.

Now you are just lying. My first post on the issue included: "I have 3 university degrees with the first one being a BSc Hons in Engineering."

As Engineering degrees are almost always 4 year degrees, and as the prime purpose of engineering is to solve multi faceted problems. If you relied on rote learning I am not surprised that you were a failure as an engineer.

As for contributing issues to global warming there are such things as Solar cycles, volcanic eruptions, the changes in the earth orbit etc that have contributed to the 0.7 degree change that has happened since the 1970s.

You have still failed to comment on the fact that the earth warmed prior to humans eg. 5 degrees over the past few millennia.

Shadow Minister,

No one is really interested in talking about a subject as dull as engineering. I have always regretted doing a degree in engineering because it is an intellectual dead end. I always recall sitting in a WC at uni and seeing a note just above the toilet roll holder which read 'Engineering degrees. Take one.'

I again invite you to define the probable causes of global warming over the past 240 years. Please identify each probable cause and then explain the reason each has resulted in a mean global temperature rise over the past 240 years. Let me start the ball rolling:

1. Burning of fossil fuels that started with the industrial revolution. Results in greenhouse gas emissions that collect in the atmosphere particularly CO2 triggering water vapour and in turn trapping heat from escaping into the cosmos. The resultant positive captured heat causing the planet to get warmer.

Your turn. Feel free to list and explain as many as you want. But please keep each to a couple of lines like I have done.

The retiring head of BP says that current fiddling and agonising about climate change will see fossil fuels still providing 73% of our energy by 2040; 56% even if the Paris Agreement were adhered to - which it isn't and won't be.

Battery storage is decades away.

As people like him have to keep pace with reality to earn the big bucks they do, we should be listening to him, and people like him, rather than no-nothing political activists and BS artists

ttbn, you just said:

'The retiring head of BP says that current fiddling and agonising about climate change will see fossil fuels still providing 73% of our energy by 2040.'

Could you please elaborate? Because I do not understand how the 'current fiddling and agonising about climate change' will result in the increasing use of fossil fuels to the point where they will provide '73% of our energy by 2040.'

Something in your claim just doesn't seem to make sense.

Mr O,

Your work and entire life makes accounting sound fun. I don't believe that you have ever done engineering as you wouldn't have offered up such moronic posts.

You asked for examples of factors that have contributed to global warming and I gave you several, that you haven't tried to refute any of these indicates that you can't, and until you at least try I will take it that you can't, and that the tedious and meaningless drivel that you and your bum chums produced is not worth the paper it is printed on.

It sounds like your report should have started with "once upon a time." and will never be read or cited by anyone.

Shadow Minister,

Stop beating around the bush. You haven't offered anything to the list I started.

I did my degree in mechanical engineering. Ask me a question about courses if you want to test me.
