Do we need nuclear energy to stop climate change? More and more voices from science, environmental activists and the press have been saying so in recent years - but this comes as a shock to those who are fighting against nuclear energy and the problems that come with it. So who is right? Well - it is complicated.

      If you want to help slow down anthropogenic climate change, here are some ways you can do so for free. TreeApp, an app that plants trees on your behalf every day. All you have to do is watch a 30 second advert. Tribaldata, an app that sells data. You can plant a tree every time you earn enough points. Both apps work on smartphones and tablets. Ecosia, a search engine just like Google, but all it's profits go to planting trees. 🏞️ Thenonprofits, a website with links to click to donate. You can plant trees, protect forests, help people who are poor, sick, provide healthcare and education, etc for free.

    So heres a problem that Elon musk actually pointed out. We have HUGE power issues. Why? Because we have very primitive power still. I'm not talking about coal or nuclear i'm talking about Battery's. Did you know the only competition to a battery is a combustion engine? Energy supply and demand is a whole SYSTEM in place to supply citizens with power on demand. But that demand and supply changes all the time and that power is NOT just sitting around waiting to be used. IT has to be generated ON THE SPOT. This is something most people have NO IDEA about. So a huge solution to helping the climate is real investment into A new contender to battery's and combustion engine and increased investment into making better battery's. Because even the best battery today is not even Equal to a Ancient combustion engine. A battery loses power and energy over time still as all you phone holder who keep their phone longer then 1 year will know what i mean about decaying battery's.

    The climate changed hundreds of times before humans showed up. How in the living fuck do you expect using nuclear energy will prevent the earth from cycling through ice and desert ages? Or maybe you aren’t referring to climate change. Perhaps you’re referring to global warming caused by human industry. Regardless, if we used exclusively renewable energy sources such as wind, hydro, solar, and by far the most constant, most abundant, and best source of energy; geothermal, the climate would still change, because that’s what planetary climates do.

      @sad pepe roni there’s significant evidence that volcanic activity in the past has caused thermal fluctuations of several degrees over a short period of time. Anyway, while I agree that we need to reduce emissions (I work as a geothermal field engineer so I do favor renewables) my main commentary was about the faulty language used; not the subject matter itself.

      You are confused. We don't try to stop natural climate changes. These changes are slow, it take thousands of years to make even 1 degree change. Therefore natural changes are not dangerous. We are trying to prevent human-caused climate change which is really fast: 2 celsius degree increase over 200 years. And it's best-case scenario, where we reduce emissions to net-zero by 2050. In the "business as usual" scenario we will have +6 celsius degree over 250 years.

    I feel like the main reason we are still using fossil fuels is because ‘the rich’ that control these decisions only want what’s best for themselves (more money). Which also contributes to them not wanting to build the Nuclear plants because they will be expensive for them, the world won’t change if these sort of people are in charge. But sadly, they are.

    Nuclear is the real future of energy production. Solar and Wind rely too much on rare metal mining for batteries needed for storing said energy and lol Fossil Fuels. Also Nuclear Fission has a much, MUCH higher energy density than any other energy source except Nuclear Fussion and Matter-Antimatter collisions. We need to move all coal plants to Nuclear ASAP if we truly want to lower CO2 emissions. If we move to Nuclear Fission we will have high energy capacity and we can then move to solving the problem of reliable Nuclear Fussion which will be able to power humanity for millions and millions of years.

    A system like capitalism that demands growth and expansion without regard for nature can only lead to crisis. We need a new system that doesn't demand ever increasing energy throughput. We could have a much better society that harmonizes with nature instead of trying in vain to dominate it. Google Murray Bookchin, social ecology, post-civilization, and degrowth.

    Infact the meat industry produces more carbon than all of the vehicles on earth, so if we make a plant based meat that tastes and looks the exact same as normal meat we can greatly cut down on carbon emissions. Also to produce meat we need a very large area to produce it and that results in heavy deforestation as the demand and population grow. But the agricultural sector requires much less space and produces less carbon than the meat industry. So if we stop investing heavily in the current meat industry and start spending and researching on plant based meat we can make and identical copy of meat. It also takes less to produce so we can make more product for less resources needed so that in poorer countries more food will be available for them to eat.

    Germany planing to close the last 6 nuclear power plants by 2025 when they provide over 12% of their energy is something that has always bothered me. If there is something the germans are badass on, is chemistry, hell, even Angela Merkel made her Ph.D at Leipzig University in 1988 on QUANTUM CHEMISTRY, which is essential for nuclear energy. Why is that the inherent excellence of german engineering is afraid of new nuclear technology? The United States, France, Finland, Sweden, China, Russia, India and South Korea are getting the upper hand on this with their plans for future traveling-wave reactors, gas-cooled reactors, sodium-cooled, small modular reactors, molten salt reactors, and even the fast breeder reactors are getting a shot after decades of doubtful tries thanks to new knowledge generated. The Italians also took the desicion of ending nuclear in the 80's, being the father of nuclear technology an italian himself (Enrico Fermi). I wish all the powerful nations saw the potential of new nuclear technology. Nuclear physics is hard, but understanding how we generate energy with it isn't.

    HI Kurzgesagt, you've skipped the global warming factor regarding electricity generation. Btw, I'm loving this channel.

    i know this would be opening Pandora's box, but we rly need to just do away w the concept of money when it comes to renewable/nuclear energy development. companies ran by or at least diligently supervised by gov'ts could theorize and thereafter produce exactly what is needed to save our planet and the costs associated could just disappear into thin air. i seriously think that's the best solution to this problem we've got

    Long ago, the world lived together in harmony. Then, everything changed when the climate change attacked. Only the nuclear power, master all of energies, can stop them. But when the world needed it most, it vanished. A decade has passed, my brother and I discovered the new nuclear power, a nuclear reactor named Deus. Although its power capacities are great, it has alot to improve before it can save anyone. But I believe, Deus can save the world.

    I love how fragments from videos "Is to late to stop climate change? Well, it's compliated", "How many people has nuclear energy killed? Nuclear death toll" and their soundtracks are referring itself and are combinated in this video.

    I appreciate Kurzgesagt's efforts to give us a little bit of hope. But knowing humans, i honestly already gave up. I will keep doing my best to contribute to world with going vegan, using my bycicle, but i know we're doomed and there's no stopping it. The only thing that gives me hope is finding a partner to spend my last years in life accompanied. :(

    Instead of building more warheads, fighter jets, advanced defence systems and other things which are not necessary right now. The investment on renewables and nuclear power should increase. Not only utilising more nuclear fuel reduce chances of a nuclear war but it will also reduce fossil fuel dependency! We dont have the means to do interstellar travel or anything beyond MARS at the moment so there is no point in trying! Once the energy sources have become stable and EARTH in general has become stable for 20+ centuries, then only we should start thinking about long term impacts such as a shift to different planets!

    maybe explore a bit on lithium batteries? Yeah electricity is great for the environments, but it didnt seem like anyone paid much attention to it.

    In think the video lacks insight on the mineral resources requiere for the transition. Batteries, windmill, solar panels, all requires not only energy but also materials, some of them not so abundant.
