Just Have a Think

My friend and fellow YouTuber, Simon Clark (who is a proper scientist with a PhD in atmospheric physics, not a hack like me!), has just published a pretty epic video that charts one possible (very optimistic, but not impossible) global scenario right through to 2100, including all aspects of climate change, geopolitics, and socio-economic dynamics in all regions of the planet, looking at how all those interactions might just combine to get our species to the end of the century with some kind of chance of surviving and moving forward into a slightly more constructive and sustainable future.






You might conclude that the content of the video represents an unachievable dream, given the shenanigans we are witnessing at COP28 right now, but I would argue that if you don't have a vison of where you want to get to, then you've got ZERO chance of getting there haven't you?

It's well worth a watch if you have a spare hour this morning.

@greatestone4eva

a doctorate doesnt really mean much there are folks who can't even do a control group correctly with doctorates. being a scientist means following the scientific method so don't ever discount yourself.

Watching the film, I could feel a breath of fresh air, no pun intended, blowing through the breeze. I agree that a pathway is at least a motivator or road map to solving the largest problem of our humanity. I appreciate all of Dave's videos and look forward to them every week. Keep up the good work!

Thank you. It is pretty dark out there and it’s not just because we’re approaching winter solstice. I hope that Simon’s arguments are convincing. The promise of tulips blooming in the spring is the only thing I am looking forward to these days. ☮️ 🌏

I saw his video in my subs feed but didn't watch it because it's very long and I didn't have a quiet hour. But I will watch it, thanks for reminding me!

I'm not sure I subscribe to the idea that you can't get anywhere without a dream. And having an unachievable dream doesn't seem to help. Willing to watch this open-mindedly as soon as I have time, even though from your description it sounds like pie in the sky.

It was an interesting exercise, but it assumes that markers we've already passed won't be passed, and that we continue to have the fossil fuel generated aerosol dimming without the fossil fuels, and that the permafrost that's already melting, doesn't melt and release the equivalent of 170 years worth of current emissions in a few years.

I am a big fan of Green Hydrogen as I think that its a superior energy storage alternative to Li batteries I was devastated to hear that Australia's $14B Green Hydrogen project had been dumped by the developer in spite of a several million dollar investment by the Federal and QLD governments. Announced 30 June I also read that on 26 June 2025 Michael Liebreich — the British analyst, engineer and investor who founded BloombergNEF and is the creator of the famous Hydrogen Ladder that ranks H2 use cases by sector— was interviewed on stage at the FT Hydrogen Summit and said that "if you actually care about the environment do not produce hydrogen". So it seems that Developers and Investors are walking away from Hydrogen and if they are walking away Hydrogen will never reach its potential. Maybe Just Have a Think can ... er... have a think about what these developments may mean?

I don't think you are allowing for the complete alteration of agricultural production. The cost of synthetically producing milk, dairy products and meat are dramatically falling. I and most consumers would prefer to buy hormone and drug free pure products. This by itself would dramatically reduce greenhouse gases. The other big game changer is batteries and alternative power. I believe nuclear especially big in Britain is finished batteries are getting so cheap, that having 5 to 7 days supply is feasible for the whole county. Again massive reduction in greenhouse gases. Finally, if this really is a huge problem for Rich Europe, we could look at having large pumping stations offshore using the heat difference in the water to offset the freshwater from Greenland .

Hello,I would like to translate your video How China is winning the GREEN ENERGY race. '' and upload it to Bilibili, a video-sharing platform in China, so that more people can watch it. I will definitely credit the original source and the creator. May I have your permission to do this? Thank you very much!

In all the years I followed your channel voluably disagreeing with you at times. I don't think I have ever told you how amazing you are as a presenter. I don't if you research and write the scripts, but just on presentation alone your increadibly professional, you remind me of Hammond & May, or If your old enough to remember them John Noakes and Peter Purvis of Blue Peter or the team on Magpie. You have that light, charming, welcomibg, upbeat voice patten that instantly puts me at ease. Have you always been this good or did you evolve it? Obviously your cutting out your out takes but you presumably must have them. Did you train as actor, it's an incredibly useful skill because one of my biggest worries about making content is my voice and my sounding like I am hectoring people when what I want to do is communicate ideas. If you learnt your communication skills how did you learn, courses, books, videos??. I have friends who are professional speakers, I really must ask them. Public speaking isn't new to me. When I was at school, I was a regular at speach day where ironically I would give talks about renewable energy (including that Nuclear was a renewable) & global warming & the environment. Another Irony is that I went everyday to school with somone who now runs a VO agency and represents a lot of famous voices. Back as a child I found the idea that the International Atomic Energy Authority was put in charge of evaluating Renewables, utterly unfair when they were effectively the lobbying arm of the Nuclear Industry. It was obvious that they would find any flaws in other Renewables they could, given that any money going to renewables was less money going to big business. I remember research into the duck, that used wave motion to create energy but was rejected because the "power supply was intermittent not stable like nuclear" despite even then people were suggesting using pumped water or air for energy storage: pumping water down to bags deep under water. So that when released the air/water could be pushed through a turbine reclaiming the energy. That even with the renewables we had then combined with Thorium Salt based reactors. We would have mostly solved Global Warming by the 1990's. OK we now also know how to stop climate change and solve our ongoing battle with poor health be it physical &/or mental. By changing our farming practices back to working with nature through mob grazing & permaculture, to sequestrate carbon in the soil, which is then able to sequestrate water And thus both bringing down the temperature and allowing the soil to look after the plants that feed us and the grazing animals that we predate on.

I confess I haven't watched it, yet. However, I do have one problem with this type of presentation. NOBODY can predict the future. And while some say that the future creates the past, or some such, we still can't see the future. We can see today. As in all problems with such things, and represented well in physics, predictions are all we can make. Some may be better than others, but none are more than that, a guess, based on questionable data and personal belief. Is the cat alive or dead? We can never know until we open the box.

Dear Mr Borlase forgive me for contacting you out of context. Frankly I have never used the "@" messaging system that would have been more appropriate. Your back catalogue is extensive so I do not know if you have covered some science that frankly I only came across yesterday but that immediately struck me as A) the trough B) a massive challenge/problem and C) most importantly a scientific understanding of a solution rather than the usual description of the problem. Yourself excluded of coarse, hence my eagerness to share it with you, knowing that you are capable of investigating it and embracing it for the wider dissemination and implementation it deserves. Two atmospheric physicists, Millán Millán, and Anastassia Makarieva have pointed out that hot humid Air needs to achieve a dew point to rain. As the world heats up there is more of H2O in the air yet the lands around the world are drying out. Trees (Jungles etc.) create their own micro climate clouds, it is these Catalysts that have been removed(Felled -Burnt) that explain why air Carrie's moisture away rather than raining. I watched You tube video "Old growth Forests -Natures Bionic Water Pumps", but frankly would love you to maybe even interview atmospheric physicists responsable for the work. As always huge respect. J.
