The problem is the tipping points. We don't know when or by what degree tipping points will affect climate change. We could see vast quantities of methane released from melting arctic tundra starting in a couple years, or maybe in a few decades. And those tipping points may slightly increase warming, or it may cause enormous acceleration in climate change.

To be more precise, the issue is that modeling tipping points is not profitable: there's no significant shareholder equity to be made on a risk-adjusted basis (as the risk is not precisely quantifiable or known and cannot be by the nature of tipping points *being qualitative* tipping points), and so there's no reason within a capitalist economy for anybody to put serious effort into investing or innovating *for* or *against* the reality of tipping points, not without government subsidies and state-direction ensuring that such research and investments would occur. No individual capitalist or group of capitalists will under any conditions be able to leverage capital toward actually ameliorating the issue: it is far, far more profitable to sell therapeutics that require consistent re-purchase on a subscription schedule, for hiked prices, than it is to sell a one-off, cheap cure intended for mass consumption. The same capitalist logic that ensures our medical industry *does not* search for actual cures (or, when cures are found, they are priced according to "what would a life-time of therapeutic surgeries and treatments and medications have costed otherwise, both directly and in terms of labour for care aids and medical practicioners, for this one individual in a nominal case without the advent of a cure?" Such that any cure -- an analogue for a direct solution to a problem -- is not economically feasible unless priced to be consumed only by those already with immense wealth, or through state-directed insurance systems that effectively subsidize access to solutions by bending to the capitalist profit motive of the "innovators". TL;DR: Capitalism is the problem, and ain't shit being done about that problem by anybody other than China. Any optimism pertaining to the climate crisis is therefore entirely inept unless it's predicated almost solely on an understanding that Chinese socialism is an infinitely superior socioeconomic system in every measurable way relevant to this -- and functionally every other -- issue; real or potential.

It was a chance to find out exactly what a 30% lock down of humanity does for the environment. I have looked all over and found very little. I’m trying to find answers to the following. 1. Could a covid level lockdown drastically reduce CO2 if maintained for long period of time? 2. Was there a change in temperature during 20,21, or 22 resulting directly from the lockdowns? 3. Did the climate science community recognize the lockdowns as chance to acquire invaluable data? All the responses to questions like mine have been very uninformative.

A lot of spoiled people that will hold onto their private transportation until someone pries it from their cold hands. Same with firearms. A society of entitlement. That attitude is starting to really catch up to us now.

The problem with this video is that it is trying to solve the problem and save the world with the same level of thinking that created the problems in the first place. If we only look at “emissions,” we completely overlook, say, the loss of forest ecosystems which actually sequester and reduce atmospheric carbon. And forests are cleared in the name of the same “development” that makes countries apparently rich. Also, agriculture is among the largest, of not the largest, contributor to global warming, and it’s not mentioned once; and it’s a problem not because of tailpipe exhausts, but the loss of forests as they become tilled soil, and soil as it becomes inorganic dirt, the collapsing of insect life as it it killed to grow crops, and water as it it polluted to fertilize lifeless dust. Yet, regenerative agriculture, plus other ecologically-inspired ideas, have the potential to reverse climate change. The query goes so much deeper than new technology wrapped in delusions of old thinking.

I can assure you that this is not the case at least in India. India was the only G20 member to meet its Paris Climate Deal goals. And one such goal, that of having 40% of its installed electric capacity from non-fossil fuel sources by 2030, was achieved 7 years ahead of schedule. We met our Paris Climate Deal goal of having 175GW installed renewable electricity capacity by 2022. But instead of saying we've done enough, our government simply tripled the target to 500 GW of installed renewable capacity by 2030. Another Paris Climate Deal target was reducing Carbon Emissions intensity by 33% over 2005 levels by 2030. India already achieved 28% in that and therefore has revised that goal upwards to 45% by 2030. So contrary to putting it on the back burner, we are achieving our climate goals ahead of time and then revising the goals upwards to do even better. Since 2015, 92% of the Coal Power Plants proposed to be built in India have been cancelled. Indian Railways is on its way to become net zero by 2030. Which is important because we are the fourth largest rail network in the world and about to become to the third largest at the current pace of expansion. In terms of ridership, we are already the largest by far. Moreover, we are on track to make 100% of our Railways electric within next two years (started from 38% in 2014 to 85% now and 100% by 2024). No G20 member is even close to this. At the same time Indian Government is aiming to increase India's share of rail freight from 27% now to 45% by 2030. This, along with the massive investment in waterways will ensure that majority of Indian freight movement that is currently done through the inefficient and fossil fuel dependent roads network will happen through green electricity powered and more energy efficient railways and waterways, massively cutting down on potential emissions. Other than that, there has been a massive reduction in emissions of vehicles due to India adopting BS VI norms which are the Indian equivalent of Euro Stage 6. On top of that, there is government subsidy, corporations and startups jumping into making and government organizations (like State Bus Transport Corporations and the military) and corporations buying up Electric Vehicles. And India's largest private conglomerates are announcing their plans for massive investment in Green Hydrogen and Electrolyzers with a target to drive Green Hydrogen costs down to $1/kg by 2030 and make India the electrolyzer manufacturing hub of the world. Mind you this goal was set by a private corporation that is among the largest oil and gas conglomerates in the world. There is so much else happening in India like Green Steel, Green Methane, Roads made of plastic waste, reforestation, biofuels, etc. And at the same time as India is doing this, India lifted a population the size of European Union from Multidimensional Poverty in the last 15 years. Point is, despite the massive challenges India faces, India is lifting hundreds of millions from extreme poverty while also fighting climate change and China and Pakistan and Terrorism. India at least, is doing its part and plans to do it irrespective of the good news.

It's still a good idea to do the things that you CAN afford, like insulate your home, keep the temperature lower in winter and higher in summer, recycle instead of landfill, grow some of your own food, and so on.

We absolutely need to decarbonize but it is also important we reduce our land foot print.

Why are we asuming what has happened the past 10 years is business as usual? Milions of people have worked hard to avoid business as usual, they are the ones that made it happen, not simple.. inertia. This was a concerted effort by those of us who took responsability. Also we are not doing well at all, according to the latest 2022 IPCC report we have already crossed 1.09 degrees of the 1.5 degree limit. " WGI assessed the increase in global surface temperature is 1.09 [0.95 to 1.20]24 °C in 2011-2020 above 1850-1900." And those are numbers from 2 years ago. Nice confetti special effects, but I don´t want to spend the rest of my life cleaning this fucking mess. Speaking of time, we have a carbon budget left for 1.5 degrees of less than 10 years and why the fuck are you talking about limiting to 2 degrees, that is a disaster scenario. The UN secretary basically said the current situation is a huge shitshow, anything short of that is a lie. We need to double of not tripple our efforts. I appreciate the efforts made to make this video, but videos like these did not help shift business as usual, videos like these are like a feel good disney movie helping people to avoid taking responsability. Climate change is simple: Eat less animal products, buy less shit, insulate your house, use public transport, fly less and demand big companies to invest sustainably. Demand big companies to do the right thing and threaten with boycotting. Demand change and threaten with boycotting. Execute your democratic right as a consumer and demand change (if you believe in capitalism). DO IT NOW, we are in a climate crisis NOW.

The "Every new model is worse" is something that has kept me up some nights. I fear the experts writing the reports are too conservative to capture the real trends.

People are nowhere near alarmed enough, we’ve already passed every tipping point and at this point we should be preparing people for the pain to come. Unfortunately due to the unwarranted optimism and misinformation many will not be prepared for the collapse to come.

Land use, and in particular animal agriculture, are my main concerns. I've seen presentations at my university on various means of minimizing land use and methane production for these systems, and while the science makes sense, I have yet to see significant enough investment from either the private sector or government.

Yes, this is the #1 worry for me as well. AAG use 83% of our AG lands, while only bring 18% of our consumed calories to the table, injustice and animal cruelty aside - it's EXTREMELY cost ineffective. Flipping it around, 82% of our consumed calories comes from only 17% of land usage from vegetables. The whole AAG system is flawed overall, subsidized from the government making it unfair and upholds an otherwise truly unsustainable system, it gets harder for the consumer to make a viable decisions with this which pushes it further. The answer is not to stick with our current habits of animal protein, waiting for some green wash technology which gives us the illusion that we're moving forward. It's take a step back, review our self and make better more sustainable choices from the bottom up. Times change and so must we, this is in the power of every consumer.

One of the reasons the CO2 emissions in the US and Europe remained flat while the GDP increased is that the West exported its industrial manufacturing to the East, mostly to China. So, emissions in China went through the roof while the West's GDP continued to climb because much of the profits from the exported manufacturing went back to the West. If you add back some of China's emissions to the West, things do not look so rosy.

But, that said - we HAVE made a difference, we HAVE more tools at hand to help this. There's more to do, there are complicated difficult decisions and processes still to take on, there is still a huge amount of resistance, most especially from all those who stand to lose billions when fossil fuels go away. They're not going to give up their wealth easily, most especially because they are indeed among those who have the resources to handle the greater dangers and discomforts of 3 degrees C.

Man certainly has an effect on the planet but at the risk of incurring wrath and spite I will say that when you look at past predictions and scenarios they never materialized. When you look at the recent spate of wildfires and floods, extremes for sure, then look at man's measures to control them (US Forest Service practice of permitting no wildfires for years creating plenty of fuel for one in a especially dry year or act of arson, urban construction and the removal of wetlands and the tiling of fields) you can find reasons for disbelief or in the case of news, gross exaggeration. No one reports on how the damming of the Mississippi River and gulf oil/gas exploration have combined to remove literally about a thousand sq. miles of tidal land. That would have made a difference for a city like New Orleans. I honestly don't know what will happen but if it truly is a nightmare why do developers still build on coastlines? I don't get it. I wouldn't.

I definitely needed this! But of course, I don’t want to get complacent

Coming back to this after summer of 2023 - while change has been possible, I feel scientific evidence starts to tells us that we have been way too optimistic about our predictions. Tipping points is one example, but this summer already saw incredible disruption of everything just being a bit hotter than usual. It feels that we are actually do not understand that much what that heating will involve. Or where tipping points will trigger. And that will add additional problem to society in general.

Do these models factor in the methane to be released from the permafrost that is thawing worldwide? The recent 'Snowball Earth' episode of History of the Earth claimed that multiples of our current carbon budget is sequestered in the permafrost and the tipping point for its eventual release has already occurred.

Great video Maiya. Most of the comments here suggest we are not alarmist enough. I think the question is… what attitude or approach will actually get us to act? Doomsday doesn’t actually motivate a lot of people. But “everything is fine” certainly isn’t helping. We haven’t won the war, even if we won the apocalypse battle. And I’m concerned that the real issue is none of these models include a holistic picture of ecosystems. Even so-called tipping points don’t well incorporate the idea that the threats are multiple - climate change, biodiversity and habitat loss, erosion, pollution of water/air/soil and the limited supply of some materials that we depend upon. The question also isn’t whether “nature” survives, the question is whether ecosystem functions that we rely upon for human civilization survive intact. Right now I’m reading how we are edging closer to Amazon rainforest tipping into savannah. And we also know even if we do make it to 2 C, just that will come with undue pain and loss. 3 C is likely and we aren’t getting the word out about how bad that could be. I would like to see a video addressing Americans specifically the difference between 2 C and 3 C on American lives/economy/democracy (selfish self preservation) and give examples in the major cities of what it might look like under those scenarios and how we can limit it to at least 2C. As someone else said, it’s still a fantasy at the moment but it doesn’t have to be.

I find it schocking how little we understand about our ecosystems in general. Most of the science was and is focused on the discovery of things that make money. And that is also how we try to fight the climate crisis aswell. By first trying to find ways to profit financially and if that is not possible then making sure that we hurt our current buisness moddel as little as possible. Even if we change the opinion of the general public there is still the issue that the opinion of the general public does not influence politics very much. There is no correlation between what the poorer 90% of the US population wants and what politcians have actually discussed or implemented in the last 20years. It is a different story for the upper 10%. So we need to fight corporate power and we need a global wealth and power redistribution if we want actual solutions. As long as we have wealth concentrated in the hands of a few people who profit from the status quo nothing will change becuase the people that could change something do not profit from actual change. We need cominity managment of water resources and land because people can actually take pretty good care of commonly owned goods if there is no way they can personally profit from its destruction. Check out the economy of the commons. I think that humans should be capable of enriching the ecosystem instead of destroying it. We have the capabilities. We just have to finally understand that money is just a tool for trade and simply holds no value on its own.

Solar might be 90% cheaper in the USA, but in South Africa, for example, the cost of solar panels and batteries has increased by more than 60% in the last few months alone. We need more regulation regarding the price of solar...

NOT ALARMED ENOUGH

One of the biggest obstacles I see towards really bending that curve down is "Net Zero". Politicians and corporate business people love to talk about "Net Zero", but it's basically a rhetorical feint to enable *actual* emissions to continue at current or higher levels, as if there are some kind of magical "offsets" that will save us from the consequences. The inconvenient truth is that only getting to *actual* zero fossil fuel emissions will enable the planet to cool to pre-industrial levels. If your eyes are open, at 1.1C we are already in very big trouble, and passing cascading tipping points. Half measures are not going to do it.

Heavy industry, shipping, and aircraft being unsolved areas of climate change vs electricity and transportation is interesting bc it's so behind the scenes that most people don't consider it. i wonder how we can change that?

Most air travel and a lot of shipping is entirely avoidable. A lot of useless junk or tourists are being transported. Ban it outright, lots of emissions saved immediately. That'll give us more time to de-carbonise what we can't do without.

Combine that with Japanese technology and Japan-India partnership and commercial shipping might be on the cusp of an EV like transformation.

What some ppl fail to realize is that humans aren't the only ones being affected, Antarctica isn't the only thing being affected. Humans might adapt to the change, but what about the other animals? What if they can't adapt?

Stead state, that is no growth and no collapse is an incredibly unlikely balancing act. Sustainable oscillation is probably achievable but nobody wants to oversee the contractions. It is a hard problem. We'll find out if the term "intelligent" actually applies to us as a species if we crack that nut. Alternative we might have an answer to the Fermi paradox, that being that the implication of intelligence actually existing implicit in the paradox has yet to be established.

All growth becomes maintenance, and all maintenance becomes waste. The reason why any system, not just our own, depends on growth. Without growth, the cost of maintenance will catch up and remove all possibility of growth for decades to come. Instead, we’d see decline.

INOT ALARMIST ENOUGH. I spent 30 years studying and cleaning up groundwater around industrial toxic waste sites. Not good. The only real progress was the regulatory bans on such sites. But some still exist. Industry makes more toxic waste than ever before. And groundwater contamination is still a very big problem. Expect from this moment on for people to prevent climate regulation every day, to slow progress with endless meetings and arguments and delays. The predictions will come true. We are in a climate mess that will get much worse in the next 30 years. You need orders of magnitude more people like me fighting to stop the fossil fuel industry. The only good news is that when the Antarctic ice breaks up and melts away and Floride is underwater, people will look back and maybe have learned something.

I think problem is question. Are we too alarmist about the climate? I feel nature will adapt, as it has always done. Question is - are we too alarmist about survival of human race and future of children? Then answer is simply no. With all 'think about children' chatter from right wing politicians, they are surpsingly carte blanche about consequences of today's actions to future world.

I think you are confusing "think of the children" with think about the unborn fetuses they seem to value more than actual living and "breathing" children. Once they are children they lose interest. We are losing species as fast as the last extinction event, I wouldn't be so certain nature will adapt to what humanity leaves in its wake.

Especially the IPCC writers, feel like they must have cherry picked their statements, I cannot believe they are incoherent with their own report that states everything short of 1.5 degrees is a complete fuckery.

The biggest progress on this topic clearly is with the beauty of the PBS host talking about climate change.

The UK used to be warmer for the Romans. When the Romans ruled Britain, known as the Roman Warm Period or Roman Climatic Optimum, is characterized by evidence of warmer conditions. This period, approximately from 250 BC to AD 400, was marked by unusually warm weather in Europe and the North Atlantic. During this time, there are indications that the climate was mild enough to allow for the cultivation of grapevines in regions such as northern England, which would typically be too cool for such crops today. The warmth of the Roman period is supported by various types of evidence, including tree ring data, which suggest that the climate was warmer than previously thought, potentially making the cultivation of certain crops like grapes in northern England feasible.

Considering pretty much all historical forecasts on warming has undershot, by a lot, and that we're heading towards several tipping points which lead to a cascade of worse things? Not alarmist enough, not nearly.

Thank you for giving us hope again. I really missed hope.

In response to the host’s assertion that almost 3 degrees will be 3x as bad as today, Al Bartlett would reply, “The greatest shortcoming of the human race is our inability to understand the exponential function.” We are well beyond arithmetic change (as though there was any correlation evident between 1 and 3 degrees being one to three times as bad… one has a body temp of 104F and it goes up to 105?
