Climate Change is predicted to spark increasing threats to food security and demands for climate reparations, fuelling geopolitical instability.
Probably the greatest risk of all, is tension over solar geo-engineering: the idea of reflecting away sunlight deliberately to modify global climate.
Recognizing solar geo-engineering as an inherently destabilising technology, because any such programme would inevitably be considered liable for bad weather everywhere, and ruling it out, would be very helpful.
This lecture was recorded by Myles Allen on 16th April 2024 at Barnard's Inn Hall, London
Myles is the Frank Jackson Foundation Professor of the Environment.
He has contributed extensively to the Intergovernmental Panel on Climate Change (IPCC), including as Coordinating Lead Author for the 2018 IPCC Special Report on Global Warming of 1.5°C. He has published extensively on how human and natural influences on climate contribute to observed climate change and extreme weather risk, and the implications for adaptation and mitigation policy.

As a retired military intelligence officer with a degrees in history and climatology, my worry is civil unrest and war stemming from climate change. They have already begun. Before the Syrian Civil War, there was a 10 year drought that devastated the Syrian agricultural sector throwing millions into the cities. When the displaced farmers demanded assistance, Assad suppressed the demonstrations leading to the war. Likewise as the Sahara has spread south into the Sahel, the Muslim herdsmen had come into conflict with the Christian farmers. What will happen as the Himalayan glaciers melt causing more seasonal variation in several major Asian rivers in China and India? It won't be pretty.

I think civil unrest due to climate policies are more likely. People don't like being poorer and colder and locked in 15 minute cities at all. I don't know anyone who takes climate change seriously anymore. Decades of predictions that never came true and political manipulations of Green created disasters. Fake fires and floods so they can kick people out of homes. I've also studied history and nothing unusual is happening to the climate.

@@grannyannie2948 Climate change itself hurts the poor. Wind and solar power are also the cheapest sources of energy on earth, and adding them to the grid isn't going to impoverish anyone, unless you believe the fossil fuel industry's relentless propaganda. Decades of predictions that never came true? What predictions? By who? Outliers? Crackpots? These do not represent a consensus of mainstream scientists. Super important to understand the difference. Fifty years ago, the scientists predicted that temperatures would continue to rise today. They predicted accelerating sea level rise, intensifying hurricanes, expansion of wildfire seasons, and increases in heatwaves, marine heatwaves, ocean acidification, extreme precipitation events, droughts , and tick-and-mosquito-borne diseases. They were right about EVERYTHING. The internet is a cesspool of misinformation, endlessly circulating "predictions" by scientists that scientists never actually made. Among these fake predictions: the polar icecaps would be melted now; New York and Florida would be underwater; the world would descend into a new Ice Age. Don't be fooled. According to investigations by Drexel University, the fossil fuel industry funds nearly 100 climate change-denying front groups, think tanks and websites, all of which work seven days a week to spread misinformation and disinformation about climate science, including the "failed predictions of scientists."

​@@mikewalker8956degrowth is where society stops their insane consumerism which will lower our overall energy expenditure. It focusses instead on human well-being by ensuring adequate healthcare, housing, locally and community grown food etc. Only problem with it is that the way our economic system is set up is that if an economy stops growing, it collapses. Degrowth needs to evolve slowly to ensure human needs are maintained throughout the process. Well, there is also the other problem that people will rebel against it because they will view it as a lowering of their living standards.

The additional effect of reducing sulphur from ship fuel is that this leads to a reduction in algae and phytoplankton. These organisms require sulphur (as do humans). If there is a reduction in numbers of algae and phytoplankton there will thus be a reduction in CO2 thatthey absorb. They account for nearly half of global absorption of CO2, and also a significant amount of oxygen production. In addition they produce DMS, which naturally cools the planet. The cutting of sulphur seems to have been done with zero thought for adverse consequences. The solar flux increase is measurable by satellite. Look up James Hansen and Leon Simons.

It also takes more energy i.e. fossil fuel burning, to remove the sulphur. This is why the policy was likely so quickly jumped on by the petrochemical industry without any call for studies that they constantly ask for with CO2 mitigation.

Return on investment in drilling for petroleum has been decreasing for 50 years nd there is no reason to believe this will change. Remember, wood used to fuel locomotives, then it was coal, and diesel. Currently natural gas and nuclear are goingvto be growth industries and renewables when battery tech improves will contribute in remote areas.

Rio Grande do Sul, a not very populous Brazilian state that produces 6.5% of Brazil's GDP, was devastated by an extreme weather event. Some municipalities were completely destroyed, the environmental deregulation carried out by the governor of that state increased the destructive potential of excessive rain. Brazil is in a position to care for the affected population and repair the damage. But if something similar happens in 2 or 3 larger, more populous and economically important states, Brazil will go bankrupt.

And we are not even calculating how much emissions militaries make. All current trillions that are given to armies due to risen war risks due to Russian war in Ukraine are simply ensuring huge future fossil fuel emissions. And they are also ensuring the dependency of fossil fuels for decades to come.

The one I know about is located in Canada. It's not a success. It was supposed to capture 98% of the CO2 and it is barely able to acheive 57%. And, the compressed and liquified CO2 is injected underground to help extracting more oil and gaz... After spending hundreds millions dollars, I don't think we are saving the planet with this kind of machine. It is not humanity that faces a climate problem (which would imply that's a technical challenge with potentially a technological solution). The real issue is that the Earth system have a human problem. As long as our human activities are not aligned with planetary bounderies, we could fix climate but it will induce a boomerang effet. We need a profound change in our relation with the Earth system.

One recommendation that never really comes up in these discussions is the voluntary and permanent reduction of one’s own footprint, with all the (minor) sacrifices that entails. After all it is us as individuals that consume all the stuff. At the moment this seems to be the only viable solution. A l l sacrifices are minor compared to the loss of this unique planet. But then again: If we really curtailed consumption in any significant way, all of our economies that have been built on the principle of unlimited growth, the more the better, would collapse. Then what? Honestly, I do not see a way out.

It comes down to this question: how many people would die if CO2 were returned to pre-industrial levels? How many would die (if any) if solar geoengineering were used? And by the way, solar geoengineering is already being done, by removing sulphur from ship fuels, and see how there has been a nearly immediate increase in sea surface temperature, that cannot be explained by El Nino or CO2. The temperature is 5 or 6 orders of magnitude more sensitive to sulphur than to CO2, so it requires a relatively tiny amount of sulphur to cool the planet. We will end up doing it, that is inevitable. The question is, will we do it in a timely and thorough way, before numerous tipping points are reached? It may be that governments will take so long dithering, that a large number of individuals such as Make Sunsets will just go ahead and do it. And governments in hot countries with deep pockets are likely just to do it, whether or not some people object. Billions of people would starve if CO2 were reduced too rapidly, as crop yields would collapse.

The only reason we haven't seen 29 feet yet is time, as ice melt greatly lags CO2. But we're well on our way, with a four inch rise since 1993 and a doubling of its rate, according to NASA. 29 feet will be catastrophic, and there is no stopping it at this point because we waited too long to reduce emissions. It's also important to note that heatwaves have TRIPLED since the 1960s, according to the EPA. Hurricane intensity has increased 8% per decade for the last four decades, according to NOAA. Extreme precipitation events are up all over the world. Drought intensity and durations have also increased. Marine heatwaves are up 20-fold, according to the University of Bern. Ocean acidification is rising rapidly. So are tick-and-mosquito-borne diseases. All stemming from rising CO2 and a warming world. According to a UN bulletin, the number of major environmental disasters from 2000-2020 nearly doubled over the previous 20 years. Thus 400-500ppm is a number hard to support.

20,000 years ago the ice was a mile thick here where Lake Erie is currently located. This ice sheet reached south nearly to the Ohio River. The Earth's total population has been estimated at 5 millon people. They were hunter gathers using wood for fuel. What caused that massive amount of ice to melt in a mere blink of geological time?

By volume, the dry air in Earth's atmosphere is about 78.08 percent nitrogen, 20.95 percent oxygen, and 0.93 percent argon, adding up to 99.96 percent. A brew of trace gases accounts for the other approximately 0.04 percent, including the greenhouse gases carbon dioxide, methane, nitrous oxide and ozone. To think that a small increase (200 parts per million in the last hundred years) of carbon dioxide would affect the weather is absurd.

The problem is that you have no understanding of what co2 does or it’s limitation. It’s not the cause of the alleged climate change nor is the increase in co2 as witness via the keelings graph all cause by human activity. Look at the Dansgaurd oeschger oscillations and the wild rose and fall of co2 before man’s intervention.. not that the co2 lead temp rises.. note that the DO oscillations show co2 pulses that go from 180-300ppm and back. Note that co2 isn’t fully locked into the ice until ye have 5000yaers worth of typical Antarctic sown layering at in uncompressed ice it’s free to move and release back into atmosphere.. This under standing equated to another 100ppm missing from ice that existed in the atmosphere thus we can assume that natural co2 rose in pulses over the last 700k yrs to 2”380ppm and the different of 40ppm to get to todays Keeling’s graphic read out is that which is man made.. The facts are that Keelings graph, which measure co2 in Hawaii is able to see seasonal fluctuations in co2 yet it couldn’t detect Covid lockdowns or industrial uptick in 2000 from china and India and when the technical person in charge of the data announced this the IPCC went wild and sacked him.

Yet isotopic analysis of atmospheric CO2 molecules today clearly shows that the 140ppm of increase since the industrial revolution has come from combusted fossil fuels, not nature. According to NASA, the Covid lockdown didn't change the CO2 reading because the absence of that extra CO2's weight on the ocean allowed the ocean to release more of its own CO2, which helped to balance out the loss.

The Make Sunsets organisation is run by two people who are very concerned about global warming. At least they are doing something. It is very easy to criticise someone, but unless you can offer a better alternative, then why not let them get on with it? At least they are not expending CO2 flying to endless climate congerences. The numbers attending are growing at a faster rate than CO2 emissions! If they really cared they would do the conference via Zoom. The professor is wrong: CO2 does not stay in the atmosphere forever, so his calculation is incorrect. There is a huge increase in plant life around the planet, particularly in semi-arid areas, because the plants grow better with enhanced CO2. This vast increase in plants represents a sink of CO2.

How do you think those balloons are made. How do you think they are lifted into the air? It takes a lot of energy to do that which is primarily via fossil fuel burning. And did you not pay attention to the fact that sulphur only remains in the atmosphere for 1 or 2 years whereas CO2 has an average lifespan of 50 years. Do the math. Think. And the alternative is renewables obviously. But whenever that clear solution is offered to anyone addicted to the notion that fossil fuels are key to the economy they always reply 'What other solutions are there'.🤪 Like brainwashed minions, the solution is offered but you ignore it because that is what Big Oil has taught you to say.

@pascalbercker7487
@pascalbercker7487 10 күн бұрын
What is your point? Here is a possible rejoinder from chatGPT4: When someone points out that carbon dioxide (CO2) makes up only about 0.04% of the Earth's atmosphere to minimize the concern about climate change, it's helpful to understand and communicate why even this seemingly small amount is significant. Here’s how you can respond: 1. **Explain the Role of CO2**: Although CO2 is a minor component of the atmosphere in terms of percentage, it plays a disproportionate role in trapping heat. This is because CO2 molecules absorb infrared radiation from the Earth’s surface that would otherwise escape into space. This process, known as the greenhouse effect, is crucial for maintaining the planet's temperature and supporting life but becomes problematic when intensified by additional CO2. 2. **Highlight the Increase in Concentration**: Over the past century, human activities, particularly the burning of fossil fuels and deforestation, have significantly increased the concentration of atmospheric CO2-from about 280 parts per million (ppm) in the pre-industrial era to over 410 ppm today. This increase is linked directly to global warming. 3. **Discuss the Impact of Small Changes**: Even small changes in the concentration of atmospheric CO2 can have large effects on the climate. The increase in CO2 levels enhances the greenhouse effect, leading to global warming and climate changes including more extreme weather events, rising sea levels, and disruptions to ecosystems. 4. **Use Analogies**: Sometimes it helps to use analogies to convey the impact. For example, a very small amount of a potent substance can have a large effect, much like a tiny amount of arsenic can be fatal. 5. **Refer to Scientific Consensus**: The overwhelming majority of climate scientists agree that rises in CO2 levels caused by human activity are driving global warming and climate change. This consensus is supported by decades of research and data collected by organizations worldwide. 6. **Emphasize Urgency and Action**: Argue that understanding the significance of increased CO2 levels is crucial for taking action. Reducing emissions and transitioning to cleaner energy sources are necessary steps to mitigate the worst impacts of climate change. These points can help frame your response to show that the small percentage of CO2 in the atmosphere is misleadingly minimal when considering its potent effect on global temperatures and climate. Do you disagree with any of this? Which part? Do you have data?

And while that is wonderful it's not the issue. The issue is how big is a million sized parcel of molecules? It's really tiny and this is why ppm is the measurement used. Next, I'd like to ask what is atmosphere? Not sure if you know but 99.97% of the mass of the atmosphere is only 100klm's high. Now if you are in all your wisdom regurgitating a factoid, I'd like to know are you saying "the atmosphere" or are you talking this fine little sliver of it? Nevertheless, let us get back to how many trillions of molecules are in the one metre above you. You realise these carbon molecules attach to two oxygen molecules that not only make the molecule wider but that they let sunlight in but trap radiant heat in like a doona on a hot summer night and that these trillions upon trillions of molecules being added to just the single metre above you are being multiplied at a rate of 2.8 per million sized parcel of air and along with this addition we are pumping overloading amounts of heat, that even if we didn't pump in more stored co2 that it's the heat we are pumping in too? We seem to let people limit the conversation to one side only of this equation, the co2 could be zero, we are emitting huge amounts of energy and for what? more plastic trinkets?

Honestly, it is frustrating and tiresome to say the same thing, over and over again: Oxygen has a natural cooling effect and when increased in volume would cool the atmosphere exponentially. Carbon Dioxide is made of two Oxygen (Dioxide) and a single Carbon and can be broken down into Carbon Monoxide (1 Carbon and 1 Oxygen), with current technology (wish we could separate them also) and O2. After which the Oxygen could then be released into the atmosphere to aid in the cooling whilst we sequester the CO in hard rock or in old Oil Wells and the like. This would double, if not quadruple the effectiveness of CCS. The alternative is to sequester twice the amount of Oxygen which has taken billions of years to create through phytoplankton's efforts and we would be left with far less for the plants to convert back into breathable Oxygen - as plants DO NOT create OXYGEN, they only convert CO2 into building blocks and release the excess Oxygen in the process. 🤙🙂‍↕️

PPS.Unfortunate Factual Reality about CO2 : The only greenhouse effect of CO2 is when it is added to actual greenhouses to compensate for the lack of CO2 in the actual Greenhouse; CO2 is not a greenhouse gas, it is a very efficient Coolant and Refrigerant, which is why it was used as the cooling gas in Britain’s Advanced Gas Cooled Nuclear Reactor. The gas efficiently acquires the mean temperature that surrounds it, acquires the warm temperate surrounding it quickly, and when surrounded by a cool temperature, sheds heat quickly as well So unlike what Fake Scientists pretend, CO2 is a long way from behaving as if it is a Storage Heater.

Making a completely false statement about CO2 with no justification and then making an irrelevant remark about coolants and refrigerants to give an impression that there is something scientific about this bare-faced lie. Hope nobody is impressed. And for the record, hundreds of the most reputable scientists not only agree that CO2 is a GHG and on exactly how CO2 acts as a GHG, they have also quantified the warming effect of CO2 in the atmosphere. The climate sensitivity of CO2 doubling is at least 2 C and could be as high as 6 C.
