I'm not up to speed with all of this but from what history shows is that it all seems to go in cycles. Every 10,000 years or so. There's a timeline chart in the Museum of London showing the approx dates, evidenced by enviromental data. Link to comment Share on other sites More sharing options...

We're fucked anyway, Its just a handy way of taxing us a bit (make that a lot) extra in the meantime! Link to comment Share on other sites More sharing options...

Mankind population is doubling every 50 years - it has doubled since Attenborough made his first documentary. If , IF , Global warming cycles (natural cycles as they are), are accelerating due to the 'Man Made' element, then unless you address population explosion, GW initiatives are futile. Simple arithmetic. End of. There's little doubt that this is the main issue, the additional food production, transport and power demands of the doubled population is the problem. Are we going to ask for voluntary liquidation of half of the population, have a series of massive nuclear strikes or release a killer superbug, any takers?

Would "globalising" Coronation Street go some way towards reduced population. Whole nations' populations would be like Lemmings Link to comment Share on other sites More sharing options...

If eco-warriers were really true their beliefs they would surely jump at the opportunity to volunteer. Link to comment Share on other sites More sharing options...
P.K. Posted April 21, 2019 Share Posted April 21, 2019 I admire them for getting off their arses and demonstrating their right to protest. As things stand I believe that the current plan is to still fall under ECHR rulings post brexit. "Taking back control...." Unfortunately climate change will need a global effort to deal with iit. Good luck with that one.... Link to comment Share on other sites More sharing options...

We do, however, seem to be caught between multiple conflicting theories of the major cause? Many say that we are the major contributor, on the other hand we have equally eminent scientists telling us that it is mainly due to other causes, such as the sun going through a warming stage, also causing increased volcanic activity, which in turn affects atmospherics and air quality? Each side accuses the other of vested interests, mainly connected with our use of fossil fuels. One side wanting to break the oil cabbals which actually rule us, the other supporting them as it preserves our current way of life, for a while? Unfortunately we are faced with making our own decisions, or having decisions forced upon us, based on information which may or may not be totally true or accurate! Erm what to say in reply. My understanding is that the pace of change is the issue and there is a huge preponderance of evidence that humanity is the driver of this. Certainly there are natural cycles but these act on the scale of 10s of thousands of years. Evidence of changes in the sun is very sparse, we’ve only had good data for two or three solar cycles and they show if anything a slight weakening of the sun - the last solar cycle had slightly fewer sun spots at solar maximum than previously. Detailed satellite measurement of top of the atmosphere radiation level is static or slightly deceasing and is totally uncorrelated with global warming. Without emissions of CO2 we would slowly be entering a cooling period but that is at a glacial pace as the Earth’s Orbital cycles and precession lower insolation into the North Pole. The increase in downward radiation from increasing CO2 in the atmosphere is multiple times larger than this and so these natural cycles are increasingly irrelevant. The properties of CO2 are well understood, unlike atmospheric oxygen or nitrogen it absorbs radiation at a certain wave length and re-emits it. As a result radiation which previously left the atmosphere is increasingly adsorbed and by random chance 1/2 of it re-emitted downwards warming the surface for a second time. The Earth is a hugely complicated system but the simple truth of the properties of CO2 is the driving explanation of the changes in the Earth’s temperature. Obviously ecological damage is far more than global warming and human population growth is causing untold damage but also demographic transition is a reality as the benefits of wealth and education spread. The world population will peak at about 10 billion. With care and the application of leapfrogging technology touchwood a balance can be found. Decarbonising the economy is a vital first step but there’s much else to do too. Link to comment Share on other sites More sharing options...
woody2 Posted April 21, 2019 Share Posted April 21, 2019 co2 levels have fallen...... yet the climate change nutter claim it's having a big impact...... i suppose the iom can finally have a ski slope during the next ice age......... Link to comment Share on other sites More sharing options...
Max Power Posted April 21, 2019 Share Posted April 21, 2019 I think the young lad did well to stand up to the 'unusual' style of the interviewer.... Too confrontational and didn't allow the lad to make his point coherently, although he was advocating extreme solutions to achieve his demands!

CO2 levels fluctuate between the North hemisphere summer and winter as there is less land mass in the south, but the trend is ever upward. Link to comment Share on other sites More sharing options...

TheTeapot Posted April 21, 2019 Share Posted April 21, 2019 Hey woody Quote Anyone can provide a quote with no source to try and back up their stupid argument To help you, the quote came from an article by Zeke Hausfather from a website funded by The European Climate Foundation. Surprised to see you using it really, seeing as according to you repeatedly Europeans are "scum". Link to comment Share on other sites More sharing options...

TheTeapot Posted April 21, 2019 Share Posted April 21, 2019 The un think it'll be 10 billion by 2050, and 11 by 2100. Edit - those figures are rounded off here's an article from the un https://www.un.org/sustainabledevelopment/blog/2017/06/world-population-projected-to-reach-9-8-billion-in-2050-and-11-2-billion-in-2100-says-un/ Link to comment Share on other sites More sharing options...
