Declan Posted November 27, 2019 Share Posted November 27, 2019 10 hours ago, Roger Mexico said: The real question is why some people need to believe that population growth makes everything impossible, even though that's not true (and fairly easy to show that it's not). I suppose they just need to find an excuse to go on being self-indulgent like they have for the rest of their lives and blame someone else for the results (ditto). It always seems to be old men that pedal the overpopulation trope. Link to comment Share on other sites More sharing options...

So a simple question from this old man Declan if I may? Give me a simple figure, a ratio, devoid of opinion or comment. What percentage of current global warming is due to Mankind - and what percentage is due to natural causes / cycles? What is the ratio? Link to comment Share on other sites More sharing options...

The earth is 4.5 billion years old, they're using information from the early 1800's to today and most of the climate data pre-1940 is sketchy at best. Green technology is such a growth area because big industry has cottoned on to the fact they can sell green crap to gullible idiots with money to burn Yeah...easy mistake for 10,000 scientists to make that.

Depends on your timescale. Over the last billion years up to around 1700, I would say 100% of climate change was natural. Since 1700, I would say 99% man made because of the way it has speeded up in a previously unprecedented way. Link to comment Share on other sites More sharing options...

My point is, if we are going to be asked for extra taxation, drastically changed lifestyles, and (perhaps) even to reduce our production of offspring - then at the very least we deserve facts upon which to make those very serious decisions. I am simply asking for facts, not opinion, guilt, blame, hyperbole, or even tropes. I have a scientific type background (I'm a Chartered Engineer) - When a problem presents, I like to commence the search for the solution with known facts (despite my age).

Surely the difficulty here is that we are dealing with opinion and probability rather than provable facts? If an engine is not working, you can usually establish the fact of why it's not working, whether it's a blocked fuel line, or a broken piston or something like that. With climate change (or medicine) you are dealing with far more complex systems so the best you can say is that atmospheric CO2 has increased, global temperatures have increased in parallel, and the consensus of scientific opinion is that there is probably a causal link between them.

Max Power Posted November 27, 2019 Share Posted November 27, 2019 This all assumes that we live on a planet with a stable climate, we don't and never have. Most of the past 100,000 years was spent in an ice age, the past 10,000 years have been spent in a warming period, allowing us to develop farming, language, engineering and civilisation in general. Prior to this, we were just trying to stay alive! Link to comment Share on other sites More sharing options...

With climate change (or medicine) you are dealing with far more complex systems so the best you can say is that atmospheric CO2 has increased, global temperatures have increased in parallel, and the consensus of scientific opinion is that there is probably a causal link between them. Yes, you could say that. But I could just as easily reverse the example. I could say that, with medicine, a dislocated shoulder could be diagnosed as easily as your broken piston example. Likewise, you can make detailed scientific / engineering calculations as to the precise moment a nuclear reaction will result in criticality, super-criticality, self-sustaining etc. Then the issues start to get a little more difficult than a blocked fuel line like this; https://en.wikipedia.org/wiki/Six_factor_formula Then, haven taken the above basics, you can re-calculate for the much more complicated real-world reactor taking into account short and long-term reactor poisoning, calculation of irradiation damage (ageing) to stainless pressure vessels and welds, reactor chemistry and physics results etc.etc. I spent decades doing so. Einstein, Oppenheimer, Rutherford and the rest struggled to achieve the above - but they got there in the end. Calculations done at Bletchley park? Again they got there in the end. Both examples achieved amazingly accurate results based on 'Probability'. The algorithms invented by the early nuclear engineers are the basis of the algorithms used today throughout the finance world (especially futures and options etc.). To say that we must base the challenge of Global Warming on opinion (your first line) is clearly wrong. But to say that we are dealing with 'probability' (again your first line) is exactly correct - but 'probability can be as amateur or as exact as you wish to make it - probability can get very very close to the truth IF you feed in the correct facts. Engineering is every bit as complicated as medicine. The human body may be super complicated, a fantastic organism, but our understanding of it is limited to the intelligence of doctors and scientists in the same way as the understanding of space, finance, engineering etc. is similarly limited. Global warming is no different. To state that "The best you can say is that atmospheric CO2 has increased......" is just wrong. That's all I'm asking for. Facts to feed in, in order to get the probabilities as accurate as possible. Then (and only then) we can formulate a plan. The blame game has achieved nothing and will continue with the same lack of success. Link to comment Share on other sites More sharing options...

The groups who are currently comforted and cossetted will not wish to be impacted on and will see to it. Particularly if it's deference to mere environmental reasons.
