  1. Has anyone heard of the MIT break through on how water evaporates? It talks about just being able to use light and no longer needed heat. Which will change the water shortage drastically for the future.

  2. So another video basically saying there are lots of possible solutions and their approves and cons to each but more research is needed. Lots of words but absolutely no information.

  3. Solar energy is the cost effective sollution to most of these problems. This is where we need to put investment money to reduce costs further and beat all other sources of energy on price, everywhere.

    Solar PV energy grows faster than any other source of energy ever, over 20% every year, which is must faster than global GPD growth. Hence solar energy will first decarbonize growth then eat all emissions. There is no shortage of materials to build and install solar PV. It can, and will grow past the energy transition. If we kept current PV gorwth, we would become a Kardashev type I civilization by 2091 !

    We now have plenty of cost-effective solutions to manage PV production variability, from demand management to batteries, as well as thermal storage. We have enough lithium to build required LFP batteries.

    Solar PV pannels can, and will be built on the moon this century, allowing to build very large solar arrays in space to directly power AI data centers in space without requiring to beam the energy down to earth as some suggest, and without the need for batteries, as the sun shines 24/7 in space.

    A solar array located at L1 Lagrange point, between the earth and the sun, can dim the sun to slightly reduce sun radiation on earth. Once temperatures have cooled down enough we can move this solar array to L4 and L5 stable Lagrange points.

    Agrivoltaïcs allows to protect crops from thermal and water stress, while harnessing solar energy. This is the only source of energy with a positive externality.

    PV energy is cheaper when decentralized, allowing to provide energy to all throughout the world, especially in the global south, helping to reach other UN sustainable development goals.

  4. No mention of transport , particulary the Areo industry , they burn tonnes of jet fuel . Every one likes to go on holiday ! Also you mention '' the last 2 centuries '' haven't there been 3 or more volcano's in that time period , don't they push out large amounts of co2 and no2 , also methane ? !

  5. All this report does is make this topic look and sound so complicated and stupendous that I throw my hands in the air and go for a walk in mother nature for a much needed hug

  6. "According to ESA, Mars' atmosphere is composed of 95.32% carbon dioxide, 2.7% nitrogen, 1.6% argon and 0.13% oxygen. The atmospheric pressure at the surface is 6.35 mbar which is over 100 times less Earth's. Humans therefore cannot breathe Martian air. Mars' sparse atmosphere doesn't offer much protection from impacts by such objects as meteorites, asteroids, and comets. The temperature on Mars can be as high as 70 degrees Fahrenheit (20 degrees Celsius) or as low as about -225 degrees Fahrenheit (-153 degrees Celsius). The current global average concentration of carbon dioxide (CO2) in the atmosphere on earth is 421 ppm as of May 2022 (0.04%). This is an increase of 50% since the start of the Industrial Revolution, up from 280 ppm during the 10,000 years prior to the mid-18th century."

  7. 1.Go to google images 2. Type in – CO2 vs temperature over 650 million years. 3. There is no correlation between them. 4. Vote against the scam artists.

  8. There is a reason there seems to be missing information from the full picture because humans contribute to the climate change and global warming yes 100% provable fact but it is not just humans contributing to temperature fluctuations on earth leading to the current crisis but it is a contribution of both humans and the sun that is where the gap is that is where the divide lies the fact that one will disagree with the other leads to less knowledge being gained and entrenchment in the theory of whichever side you've chosen but it's not about sides it's about fact the fact is that humans do contribute to the CO2 levels which have a longer lifetime than most other global warming gases that get released and that adds to the problem but the greater problem being the sun's effect on the earth at the moment and humans aren't helping by adding to that we can solve the short term by stopping our shenanigans and then come up with solutions to solve the long-term sun shenanigans

  9. 19:11 because we are comfortable and distracted with our consumerist habits, leaving it for later and not being able to work together and would rather individualise the issue, instead of tackling the root cause being who has conditioned society to be this way, instead of an existentialist introspective based society.

  10. Climate science is clearly one of the most immature sciences today. If you actually do the research, you will see that John Tyndall"s experiments on CO2 in the 1800's did not account for the effects of gravity on convection in the real world. This is where the myth and lie that increasing levels of CO2 in earth's atmosphere will cause a greenhouse effect and warming can be traced to, and only lazy "scientists" believe this!

  11. Spend long enough on this problem and you’ll realise that our efforts have been a joke, the capitalist system can’t deal with climate change and we’re not going to get on top of this problem.

  12. the point about social dynamic might be one of the biggest issues here:

    there is a lack of understanding how climate change, renewable energy, intelligent energy use, gene editing and having more money to spend is interconnected. and a blatend disregard of facts and the willingness to adapt.

    i joined a political party (partei der humanisten) because this bothered me and funnily enough through a video of extra3 i want to learn how our laws slow down progression and what could be done to change that.

    if we can stop lobbyists working against progress and implement stuff that really works long term instead of falling for greenwashing i am convinced we could make huge steps in the right direction really fast.

  13. As an environmental engineer, I would like to thank you for the great video – it is really informative! Keep up the great work – the way you communicate science is interesting and engaging. We need more people like you!

  14. Sorry but we know that we could achieve near net zero but do not know how to reverse the climate change, we would only be able to wait a couple of hundred years to see if we will have managed to do it. How can we get China, India and the USA to join us and at least stop using coal?

  15. How about this for a study candidate:

    Man-made 'global warming' NOT as a result from fossil fuel burning!

    How does convection affect the climate? Convection within the atmosphere can often be observed in our weather. For example, as the sun heats the Earth's surface, the air above it heats up and rises.
    (Sources: the UK Met. Office – amongst many: it is an accepted fact the sun heats the ground and the radiates heat warms the air)
    ——
    The darker the object, the better it emits heat, because it's a better absorber of light. On the other hand, a white object appears white because it reflects all the different wavelengths and absorbs little to no light. It doesn't absorb much energy, then, and puts off little to no heat.
    (Source: basic science: it is an accepted fact that darker things radiate far more heat).
    ——
    Findings demonstrated that temperatures around a solar power plant were 5.4-7.2 °F (3-4 °C) warmer than nearby wildlands.
    (Sources: Physics.org – amongst many: it is an accepted fact that these things radiate heat).
    —–
    Deforestation increases the surrounding air temperature.
    (Source: anyone who has walked into a forest on a HOT day and noticed it is a LOT cooler under the trees – trees absorb heat as well as sunlight 🙂).

    There are DOZENS of more examples – but I don't want to lose your interest…

    SO… the last 50 years has seen a ridiculous increase in dark surfaces (roads, house roofs, etc covering the globe. And a huge increase in other structures that trap and radiate heat long after the sun has set.
    And now we are chopping down ever-more trees as 'biomass' to feed the green agenda.

    I'd love to see a proper study into all of this.

    —–

    Oh… and I'm glad the Panama Canal was mentioned… but the report failed to mention that the canal problems started after it was massively increased in size to accommodate ever-larger ships – BUT nothing was done to increase the size of the reservoirs that were ESSENTIAL to maintain the operation.

    So finally…
    This is the big problem – no-one is looking into GLOBAL factors when making statements about 'global' warming.

    And very finally…
    I give you the Medieval Warm Period!
    A thousand years BEFORE fossil fuels were a wet-dream in the petro-giants' trousers – it got warmer… a lot warmer: grapes were being grown in the UK, for heavens sake… a thousand years before all of the current 'reasons' quoted for 'climate change' 🤣

  16. …planting more forests that won't easily fall victim to wildfires… (11:40 into this report).
    I'd love to hear how that is done!
    Bio-engineer fireproof wood 😂
    Install a forest-sized sprinkler system (with sufficiently fire-retardant hoses) 🤣🤣🤣

    I mean… wtf?

  17. Door number 12.
    Population!

    Look at any graph that plots population growth.
    Look at any graph that plots temperature rises.
    Put the two side-by-side…

    One matches the other. TaaDaah!
    More people… more heat.
    It's inescapable. Whether it is poor people burning fossil fuel for a basic living, heat and food… or rich people running luxury items like air-con…
    More people = more problem.

    The answer is as obvious as it is ugly to fix.

    You can't have more people and less problem at the same time: there is no current science that will make this happen 😢 (I'm happy to be proved wrong)

  18. 19:30
    Activism should probably be the one area where the burden of climate change is on the individual, instead of via policy.
    What are the net CO2e emissions of a protester who cut down a tree to make a paper protest sign, then drove in an SUV across town, and bought lunch with foods imported from overseas? It leaves a hypocritical taste; "tofu for thee, not me."

  19. If climate change is real then cut back on industry as well. Don't buy new keep repairing your old items to save the planet. A 3 day week would save a lot of energy but will they do that or it is not such a problem after all. It is only the households fault. we're being conned

  20. Net Zero means everyone dies because nobody can survive without Carbon.
    The Climate Change cult is all about making billions of dollars with hysteria.
    The Climate Cult has been saying the same nonsense since the 70’s.
    Nothing has changed.

  21. Exponential population growth, an economic philosophy predicated on unlimited growth, and corrupt, self-serving leadership making short-sighted decisions. These are the primary causes of climate change and the destruction of global ecosystems. We have no answers to them because they reflect human nature. What Simon talks about may offer small palliative relief, but are not solutions. His cheery delivery makes him pleasant to listen to and, like wind and solar power, offers us false hope.

  22. In Germany we have a village that achieved beyond net 0.
    What happens after? Economic growth… Restoration of schools. playgrounds. The growth was possible, because energy became much much cheaper.

    Look at Feldheim and others. The consequences are amazing, mostly for the people who live there. The money stays in the region and that shows!

  23. 11:01 no. If we build more walkable dense neighborhoods heat island effect would be lowered. Because it has been proven neighborhoods with mid and high rises have a lower temperature. Because tall buildings provide shade.

    Also tall buildings are more energy efficient. Roof top plants would lower the temperature even more.

  24. 2:28 We say "MEHTH-ane" in the US because we love our MEHTHamphetamine

    (I'm jk, I know that it's the ssme prefix. So methamphetamine would be "meeethamphetamine" in "meeethane" regions)

  25. As someone looking to move into climate research in the polar regions, I found this video eye-opening. Especially at the breadth of issues that are a priority. If any polar scientists would be able to build upon these research topics, I’d appreciate it.

  26. I’d love to see some proper funding into biomass estimation. Above ground biomass isn’t too bad, but below ground and aquatic biomass are extremely rough estimates. Its very difficult and expensive to measure and theirs no market potential at the end, so its pretty much just college kids.
