The climate is lost when we fill this cube
Рет қаралды 41,517
Күн бұрынThis video was created in partnership with Bill Gates, inspired by his new book “How to Avoid a Climate Disaster.” Find out more here: gatesnot.es/3bdZ4CK
In this video I talk about how much carbon we can emit into the Earth's atmosphere before climate change gets really serious. This is based on a paper published by Allen et al (2009) www.nature.com/articles/natur... which claims the atmosphere has a capacity of approximately one trillion tonnes of carbon. This capacity is contributed to by global carbon emissions of carbon dioxide, methane, and other compounds. In order to prevent catastrophic anthropogenic climate change, we must avoid emitting the trillionth tonne of carbon, it's that simple! Achieving this is of course is more difficult, and will involve sweeping changes to power generation, agriculture, transport, manufacturing, and more. This video is a brief introduction to how we need to change our economy in these sectors to limit carbon emissions and prevent catastrophic climate change.

My flat is connected to a community heat network. There's no gas boiler in the property, in fact there's no gas supply to the whole building. What there is though is an energy centre next door which right now has large gas boilers and the hot water is available to the area via highly insulated pipes, which on its own is better than everyone having their own gas combi boiler. In the next few years though this will be connected to a wider heat network that will use the waste heat from power stations and industry to heat water and send that to a huge number of homes in the borough. Once you can do this kind of thing again, Simon, you should come and see what's going on. I'm sure the scheme would be very happy to show you around it all. I'll drop you some information.

For sure the best way to reduce road traffic emissions is to get people on public transport and improve the supply/distribution chain, not to just make everything electric; technology can make a small dent but we need to address the total energy we spend on transportation instead of just shifting the source from gasoline to coal. The reason personnel traffic is such a huge polluter is because of how horribly inefficient it is to carry small groups of people in a single vehicle when we can carry hundreds at a time with public transit. Improving train infrastructure is also a huge deal for long-distance shipping because trains are vastly better than semi trucks at long-haul shipping. Trains to do cross-country shipment + semis for final distribution, more people on public transit, far less transport emissions. Expecting technological advancements to magically whisk away climate change is wishful thinking and is a guarantee that we'll be in very deep water (sometimes literally if you're a coastal resident) within our lifetimes.

Before I got this video served by the algorithm, I listened to an hour-long interview today with someone here in Sweden involved in planning the worlds first carbon-neutral cement plant, Heidelberg Cement's plant in Slite on Gotland after it's upgraded. It's currently producing around 75% of the cement used in Sweden and their plan actually seems feasible. It might even become carbon negative as they increasingly use biofuels and then carbon capture+sequestration.

YES EXCELLENT POINT. However it turns out most of the fertilizer emissions mentioned are actually just from the energy cost of producing ammonia, which could be zero emission if they just used renewables to heat and pressurize the process. there are minimal emissions of nitrous oxide (in terms of way less than 1% of greenhouse gasses worldwide), but those are negligible in comparison.

Great video! One thing I would point out though, and that is I guess the only silver lining to climate change, is that with enough green energy production, carbon recapture could increase as power becomes cheaper. This would mean that other industries that will take longer to go green due to inherent limitations, will be allotted more time to do so. Of course, this does not mean those industries should get a pass, they still need to go green, but carbon recapture buys them time for the green technology to mature and become affordable or profitable.

Great video, the visualisations made your points very clear. It would have been interesting to see/hear about how we can also sequester more carbon too. You briefly mentioned natural processes such as acid rain, but can we also amplify our ability to sequester carbon in addition to our carbon emitting reductions? How big an impact could that have? I watched a great film a couple of years ago called '2040' which described a seaweed that can be grown that is very effective at sequestering carbon. Surely if we're to effectively fight the effects of climate change we need to both reduce emissions and take more carbon out of our atmosphere too.

Whose water supply is going to get cut off due to dams built for hydroelectric power? Who's going to face the landslides and floods because of the dams? These are tough questions that we need to answer immediately, otherwise we might end up creating more inequality. I'm from a country where socially, the field is uneven to say the least. I kind of feel helpless at the face of the climate crisis, because running into renewables haphazardly will make those inequalities more stark, but we also need to act now. IDK, just a thought.

Trees for carbon capture n don't work. First, every quarter century, fools like Trump or Bolsanero come along & allow their cronies to cut down what you've planted. See what's done to Bialowiecsa Forest, Poland by the PiS government. Woods are on fertile soil, timber is value, even stabile govt can't keep it safe- even swedish old growth is dwindling. How do even expect to check on protection of far off forests in out of the way corrupt countries ? More important, there's simply not enough open land to plant them co2 Capture trees. Farm folk live there, if not, it's already forest or it's unfertile or too dry. Greenpeace calculated about 2 times the surface of india is needed for current offset schemes using trees. We don't have that kind of empty land surface. We need something more durable. I'd go for seeding ocean plankton, the oceans contain about 60 times the 1880 atmosphere carbon content, or 16 times the total biosphere content including soils. It might affect ocean ecosystems - but as long we're not living in there, we could probably survive with that.

I just want to put a small correction to the steel production point: It isnt completely true that it absolutely required to produce CO2 in making steel. For example Salzgitter AG (a german steel producer) has their SALCOS project in which they build plants for direct hydrogen reduction of metal. (Not sure for which metals it works, though) You might not get that value to 0 but there is still a lot of room for reducing those emissions as well. Some kind of carbon capture is still necessary, though.

One of the arguments I get against electric vehicles is that: "You're just ignoring the problem. Most of the energy that powers your car still comes from coal; and the lithium mines that build the batteries for your car do more damage to the Earth than gas cars ever do." While that is a fair point, it's important to consider that EV's are NOT the solution, but merely a stepping stone guiding us towards the solution. If we have gas cars, not only are we burning coal to fuel the car up, we are also burning coal to power the batteries. If we move towards EV's, we wipe out the emissions coming from fueling the car itself, so we can focus on removing the emissions from where we get our energy, and actually start moving towards better energy solutions like nuclear, renewables, and from space itself. As for the lithium problem, we can likely get those materials from our asteroids, or other planets; depending on where its found

Fun fact, at the end of the last ice age atmospheric C02 was so low at less than 200 ppm it was perilously close to causing mass extinction of plants which would have been catastrophic for life on Earth.

@@bluesbr0ther588 Doh! it was 10 000 years ago when the great glaciers extended into the southern US and southern UK. By any manner of means it was what everyone understands as an ice age, the age of glaciation. We are now in an interglacial and hence in all probability will go back into another age of glaciation otherwise known as an ice age. C02 when the last glaciation ended was around 180ppm. Plants die at around 150 ppm. You guys specialise in talking patronising nonsense.

If only there was some way we could voluntarily, over a few generations, reduce the net amount of emissions we require.

Decreasing meat and dairy consumption would definitely not decrease carbon emissions meaningfully, and meat consumption is crucial for feeding people and not wasting otherwise unusable farmland where only grass can grow. Removing cows from existence would help hypothetically, but we don't really have many more cows here now compared to buffalo/bison populations naturally living in the US, and many other countries are a very similar story. Calling livestock a significant anthropogenic source of CO2 is pretty naive considering that there were basically just as many animals here before european settlers came. Meat consumption is crucial if we intend on feeding the whole world, seeing as how most land in most countries cannot be used to farm edible grains. We absolutely can reduce methane emissions from beef, however, and since methane can be a relevant emission depending on local environmental factors it's definitely a meaningful metric to decrease.

Another great video however I have to disagree with you about fertiliser, a growing proportion of farmers are now using no dig or no till farming methods which includes keeping all waste/weeds on the land therefore reducing the need for fertlisers.

Even if we were to agree that ending capitalism would be beneficial, it is also completely unrealistic. You could choose to put all your energy into that goal, convincing people and fighting and whatnot, but do you actually think you'll do it before 2050, and with enough time left to then impose the necessary changes? Obviously I don't agree that it's even a good idea to begin with, but my point is that even if I did, I would still not push for it because it's not likely to succeed in time. You could draw a comparison to nuclear power, which I still think would be a great way to lower our emissions. Sadly, it's also a no-go because of politics, so I choose to focus on other goals instead.

Excellent content as always. However, the agriculture sector has a bit of a catch-22 to deal with if it needs both to eliminate animal farming and to find a mostly green source of fertiliser (synthetic fertiliser has an even bigger footprint than animal waste and accounts globally for roughly half of the supply of fertiliser), while using arable land sustainably.

Thank you for acknowledging Nuclear Power! I'm not against alternatives either, we just REALLY need to move beyond the Nuclear Power stigma. The technology has been improved and refined massively, there is incredible positive potential with Nuclear.

It is a shame that he failed to point out this is ultimately probably the only way to really decarbonise global shipping too. Modern container ships are more than large enough to house a small nuclear reactor and all its shielding. Also most of the increased operational costs that make them less attractive are not only offset by higher speed and thus more revenue. But they also mostly stem from there being all of one civilian facility suitably equipped and staffed facility to maintain a nuclear vessel in the world. This is a problem that would go away with the help of some initial subsidies to nudge new ship construction in that direction. Since that would create the incentive for facilities to invest in being able to capture the market for maintaining these new vessels.

If we manage to buy 100 years it will be huge. Progress in technology will help us buy more in te future. Look where we were 100 houndred years ago. Cars were a thing of the future, most people did not have access to eletricity. Imagine how our life will look in another houndred years assuming we will survive :P.
