2. 30 years ago I was totally on board with climate activisim, we were told that if we didn't act "IMMEDIATELY", 6 foot of sea level rise by 2000. In the early 2000s I read "State of Fear" fun syfy, but I read the prolog, and realized that I had fallen for the propaganda.
   In the past 30 years the world has actually improved in all measures including climate. Sever weather conditions have lessened across the board. The earth is greener and less poluted

8. Congrats on your channel showing support for awareness. The worse thing about climate change is what everyone continues to avoid talking about. Capitalism, cost of living, government oppression, pollution, waste of resources and abuse of nature. Advanced climate change with cloud formations is more like this ///// fighting with atmospheric release and contracting building excessive thermal temperatures creating unstable weather patterns that are unpredictable. Excessive nitrogen and c02 combining with all other pollution gases creates a chaotic environment for plants, crops, animals and water supplies. Humanity is causing global extinction just to make money to not only pay cost of living but create and buy consumer products that isn't really needed. All solutions that are implemented are focused on return of investment so climate change will continue to get worse until massive food shortages begin. There is no balance with nature on a worldwide scale. It is more like 90% humanity and the rest is 10%. Domination without diversity kills everything by human manipulation weeding out what they don't like and playing god with nature. The cause and effect is humans are flawed by competition creation without thought of consequences. Money is the problem and money won't fix the problem. Capitalism and all currency on the planet must be abandoned for a new future or there will be no future!!
   Thanks for the supportive videos and keep up the good work. 👍

9. Over 30 years of research with my own travels examining climate change. I have seen stuff that never hits the news. Crops beings genetically altered illegally without public knowledge. Species being wiped out to increase harvest to meet demands. Ecosystems completely going extinct from lack of diversity with extinct species from human activities. Water tables filled with concrete to force compliance centralized water sources. Chemicals being used to evaporate rivers and poison root networks of ancient forests. Private companies secretly diverting water underground without any knowledge of what is happening. You can probably guess the companies behind that one. We built a physical simulator for climate change in a hermetically sealed building. At the current pace of destruction of humanity by the 2030's a massive event will occur increasing global temps up to 12 degrees inciting a chaotic chain of events with global weather patterns. The threat is real and nobody wants to do the responsible thing. Humanity will watch and wait until it happens and then they will want to do something out of necessity. By then it will be too late to do anything. 90% of the world economy will have to shut down all non essentials to the basic needs 1 for 1 consumer products rationing for equality without cost of living. If this happens then the earth will calm down and regulate in the 2030's but still the damage will be done but it won't get any worse. It will take 100 years of healing before nature will balance out again with regrowth from the damage. Humanity will have to sacrifice the wants for the necessities. Technology must be used responsibly and if AI technology continues to be integrated with everything for capitalism then earth is doomed. Wasteful resources like cryptocurrency, competitive consumer product waste and entertainment demand merging with internet services is creating chaotic energy and data uses the world is not prepared for. Humanity must focus and slow down to plan responsibly for the future of the planet with all of its inhabitants.

11. I don't think what you call "climate deniers" don't believe the climate is changing, or the the Earth is warming up. What many of us don't agree with is the outcome. You guys I call "climate doomologists" because it's always doom and gloom with you – what makes you an expert on what WILL actually happen when the Earth warms? Your models have ALWAYS been not only wrong, but WAY wrong! The end of the world has been predicted since the 1970's, and each decade when the end doesn't arrive, you move the goal post. By now we should have been under a km of water and 5 degrees warmer – what kind of model was that? Why should we believe anything you say now, when your track record is 0? Also, claiming your scientists are right and the deniers' scientists are wrong is also cherry picking. You accuse us of what you do! Looking at the FACTS – what has actually occurred, and what has happened in Earth's long 5 billion year history, it is safe to say that the Earth is NOT being impacted by man's burning of fossil fuels to the extent that you claim. Man is NOT as big and powerful as anyone thinks – we are not even fleas on a dog, more like viruses on a flea on a dog. The Earth and Sun control climate change on our planet, anything else is simply not enough of an influence to affect it more than a nudge – and that nudge we are doing might actually be HELPING save the planet, not doom it! For those ignorant enough not to have done the research, we are actually coming OUT of an ice age event in our climate – so of course the planet is warming. We want it to. We need it to. If we do as you want and STOP man's contribution to the extra CO2 the planet has, we may only be hastening our returning plunge back into the next ice age. More people and life in general die from cold than heat, and 99% of all life on or planet died during the last ice ages. Because we need heat, water, and food to survive, none of which can be found on an ice ball planet! Now, 50,000 years ago when the temperatures were 8 degrees plus warmer, life thrived! CO2 levels were 8000 ppm (today 400…) and plants and animals survived well on the "hot" planet. So please, tell us in your wisdom, how lowering the temperatures of our planet when we haven't even successfully and fully finished the last ice age, is this going to help us survive? What if you guys are the ones trying to destroy our future? Be careful what you decide to preach and teach until you know ALL of the answers, which, unfortunately, nobody has, because nobody has done the necessary study that is all-encompassing that takes into account every factor that affects climate into account. It takes more than measuring CO2 and ocean level rise to know this – all fields need to be combined and the relationships understood before anyone can definitively say "this is true." Until then, it's just your opinion, as this is mine. I for one will continue to live my life to the fullest. Yes I burn fossil fuels, not unnecessarily, but I do drive and fly when needed, and this may end up being the "tipping point" that causes our planet to avoid the next ice age. That's my belief, and until I see this all-encompassing study that proves me wrong, I will continue to do so.

    You admittedly make great videos, but I think you should make a rule to keep comments on topic for the main part as something that puts me off following channels is when they have a suck-arse comment section to the extent it just spams any meaningful comments into obscurity.

    Before anyone says I’m being hypocritical for spamming with moaning, it’s not. This braindead behaviour needs to be extinguished. I agree with everyone’s sentiments btw, but chill, nobody cares that you love the fact she’s hit 10k. I want to hear people’s perspective on the content.

18. Our planet is burning, melting, and flooding and we haven't even ended fossil fuel subsidies yet. This is an absolute no-brainer but the @DNC promised not to end them.

20. On 22 August 2022, at the Cryosphere 2022 Symposium at the Harpa Conference Centre Reykjavik, Iceland, glaciologist Professor Jason Box said from about the 15½ minute mark:

    The James E Hansen 𝘦𝘵 𝘢𝘭. (2023) paper titled 𝘎𝘭𝘰𝘣𝘢𝘭 𝘸𝘢𝘳𝘮𝘪𝘯𝘨 𝘪𝘯 𝘵𝘩𝘦 𝘱𝘪𝘱𝘦𝘭𝘪𝘯𝘦, in the Abstract included (bold text my emphasis):

    """Discussion [184] with field glaciologists¹³ 20 years ago revealed frustration with IPCC’s ice sheet assessment. One glaciologist said—about a photo [185] of a moulin (a vertical shaft that carries meltwater to the base of the Greenland ice sheet)—‘the whole ice sheet is going down that damned hole!’ 𝗖𝗼𝗻𝗰𝗲𝗿𝗻 𝘄𝗮𝘀 𝗯𝗮𝘀𝗲𝗱 𝗼𝗻 𝗼𝗯𝘀𝗲𝗿𝘃𝗲𝗱 𝗶𝗰𝗲 𝘀𝗵𝗲𝗲𝘁 𝗰𝗵𝗮𝗻𝗴𝗲𝘀 𝗮𝗻𝗱 𝗽𝗮𝗹𝗲𝗼𝗰𝗹𝗶𝗺𝗮𝘁𝗲 𝗲𝘃𝗶𝗱𝗲𝗻𝗰𝗲 𝗼𝗳 𝘀𝗲𝗮 𝗹𝗲𝘃𝗲𝗹 𝗿𝗶𝘀𝗲 𝗯𝘆 𝘀𝗲𝘃𝗲𝗿𝗮𝗹 𝗺𝗲𝘁𝗲𝗿𝘀 𝗶𝗻 𝗮 𝗰𝗲𝗻𝘁𝘂𝗿𝘆, 𝗶𝗺𝗽𝗹𝘆𝗶𝗻𝗴 𝘁𝗵𝗮𝘁 𝗶𝗰𝗲 𝘀𝗵𝗲𝗲𝘁 𝗰𝗼𝗹𝗹𝗮𝗽𝘀𝗲 𝗶𝘀 𝗮𝗻 𝗲𝘅𝗽𝗼𝗻𝗲𝗻𝘁𝗶𝗮𝗹 𝗽𝗿𝗼𝗰𝗲𝘀𝘀. Thus, as an alternative to ice sheet models, we carried out a study described in Ice Melt [13]. In a GCM simulation, we added a growing freshwater flux to the ocean surface mixed layer around Greenland and Antarctica, with the flux in the early 21st century based on estimates from in situ glaciological studies [186] and satellite data on sea level trends near Antarctica [187]. Doubling times of 10 and 20 years were used for the growth of freshwater flux. One merit of our GCM was reduced, more realistic, small-scale ocean mixing, with a result that Antarctic Bottom Water formed close to the Antarctic coast [13], as in the real world. Growth of meltwater and GHG emissions led to shutdown of the North Atlantic and Southern Ocean overturning circulations, amplified warming at the foot of the ice shelves that buttress the ice sheets, and other feedbacks consistent with ‘nonlinearly growing sea level rise, reaching several meters in 50–150 years’ [13]. Shutdown of ocean overturning circulation occurs this century, as early as midcentury.

    In the journal 𝘈𝘵𝘮𝘰𝘴. 𝘊𝘩𝘦𝘮. 𝘗𝘩𝘺𝘴., 16, 3761–3812, 2016, included the paper by James Hansen 𝘦𝘵 𝘢𝘭., titled 𝗜𝗰𝗲 𝗺𝗲𝗹𝘁, 𝘀𝗲𝗮 𝗹𝗲𝘃𝗲𝗹 𝗿𝗶𝘀𝗲 𝗮𝗻𝗱 𝘀𝘂𝗽𝗲𝗿𝘀𝘁𝗼𝗿𝗺𝘀: 𝗲𝘃𝗶𝗱𝗲𝗻𝗰𝗲 𝗳𝗿𝗼𝗺 𝗽𝗮𝗹𝗲𝗼𝗰𝗹𝗶𝗺𝗮𝘁𝗲 𝗱𝗮𝘁𝗮, 𝗰𝗹𝗶𝗺𝗮𝘁𝗲 𝗺𝗼𝗱𝗲𝗹𝗶𝗻𝗴, 𝗮𝗻𝗱 𝗺𝗼𝗱𝗲𝗿𝗻 𝗼𝗯𝘀𝗲𝗿𝘃𝗮𝘁𝗶𝗼𝗻𝘀 𝘁𝗵𝗮𝘁 𝟮°𝗖 𝗴𝗹𝗼𝗯𝗮𝗹 𝘄𝗮𝗿𝗺𝗶𝗻𝗴 𝗰𝗼𝘂𝗹𝗱 𝗯𝗲 𝗱𝗮𝗻𝗴𝗲𝗿𝗼𝘂𝘀, included (on page 3766):

    """A sea level rise of 5m in a century is about the most extreme in the paleo-record (Fairbanks, 1989; Deschamps et al., 2012), but the assumed 21st century climate forcing is also more rapidly growing than any known natural forcing."""

    It seems around 5 m of SLR has previously occurred within a timescale of a century according to the paleo-record, and the current climate forcing is more rapidly growing than at any time in the paleo-record, so I’d suggest it’s not unreasonable to expect a similar accelerating multi-metre SLR within this century.

    The World Meteorological Organization (WMO) published their report titled 𝘚𝘵𝘢𝘵𝘦 𝘰𝘧 𝘵𝘩𝘦 𝘎𝘭𝘰𝘣𝘢𝘭 𝘊𝘭𝘪𝘮𝘢𝘵𝘦 on 19 Mar 2024, where in Fig 6 (on page 6) indicated that the SLR rate of an average of 4.77 mm/year was observed over the period Jan 2014 through Dec 2023, with an acceleration at 0.12 ± 0.05 mm/y². This suggests the SLR rate is now around 5 mm/y in 2024. The SLR doubling rate since satellite altimetry data began in Jan 1993 has been around 18 years. So an SLR rate of 5 mm/y now, in less than 2 decades then accelerates to 10 mm/y, and then 20 mm/y, 𝘦𝘵𝘤, assuming an exponential progression.

    See also Table 3.2 in NOAA’s Feb 2022 report on SLR titled 𝘎𝘭𝘰𝘣𝘢𝘭 𝘢𝘯𝘥 𝘙𝘦𝘨𝘪𝘰𝘯𝘢𝘭 𝘚𝘦𝘢 𝘓𝘦𝘷𝘦𝘭 𝘙𝘪𝘴𝘦 𝘚𝘤𝘦𝘯𝘢𝘳𝘪𝘰𝘴 𝘧𝘰𝘳 𝘵𝘩𝘦 𝘜𝘯𝘪𝘵𝘦𝘥 𝘚𝘵𝘢𝘵𝘦𝘴: 𝘜𝘱𝘥𝘢𝘵𝘦𝘥 𝘔𝘦𝘢𝘯 𝘗𝘳𝘰𝘫𝘦𝘤𝘵𝘪𝘰𝘯𝘴 𝘢𝘯𝘥 𝘌𝘹𝘵𝘳𝘦𝘮𝘦 𝘞𝘢𝘵𝘦𝘳 𝘓𝘦𝘷𝘦𝘭 𝘗𝘳𝘰𝘣𝘢𝘣𝘪𝘭𝘪𝘵𝘪𝘦𝘴 𝘈𝘭𝘰𝘯𝘨 𝘜.𝘚. 𝘊𝘰𝘢𝘴𝘵𝘭𝘪𝘯𝘦𝘴, which projects a global mean sea level by 2050 (relative to the year-2000 baseline) will likely be in the range of 0.15 m (for a low emissions scenario) to 0.43 m (for a high emissions scenario). By 2100, the range is projected from 0.3 m (low) to 2.0 m (high).

    That raises critical questions about whether it would be worthwhile to continue defending coastal infrastructure/property, or instead, abandon them and retreat. How do you defend against an apparently relentless and accelerating SLR?

21. If your political party talks about economic growth it's a solid bet that they're not serious about climate… then again you could say the same about them having a real chance of getting into government.

22. Voting requires great care, especially under FPTP systems, where a vote for ‘the best policies ‘ may simply enable a party with bad policies to remain in power. Example ; 900 votes for Green Party in Uxbridge enabled Tories to win, emboldening Sunak to row back on what little climate change work the Tories were committed to. Careful realism is needed in deciding how to vote tactically under FPTP

23. Excellent, I wish that our politicians could be made to watch this.
    It never ceases to amaze me how little attention these issues receive. They are more important than anything else happening in the world. Not long ago, the BBC decided to include a feature in the main news on climate change, naturally appearing at the end of the bulletin after more important stuff like what Taylor Swift was up to. The feature was about warming coastal waters and the effects on shellfish, concluding that life was going to get tough for them, they may need to move north. The BBC knows that people don’t want to be bothered by hard truths about devastating impacts so they trivialise the subject. I think that this trivialisation of inconvenient truths is as bad as outright denial.

24. 13:30 this isn't the first time I've heard it stated that if human emissions were theoretically reduced to 0, temperature increases would stabilize. What about Hansen's "Global Warming in the Pipeline."?
    We've both pumped the ocean full of so much heat in the last century and completely decimated the forests both on land and in the water. How is the ocean not going to radiate heat back into the atmosphere and what's left of the natural carbon cycle of the pre-industrial era to take up all our excess carbon and other emissions? It sounds like a climate change denier level amount of copium/hopium but I'd love to understand more.

25. 30 years ago, we were told reduce aerosols, now with aerosols reduced by 70%, whoops sorry our mistake, had the opposite effect, but we might put some back. Seems they are trying to calculate an answer to the sum of a number of variables, where they have no value for the variables, or even know how many variables they need to get values for.

29. Yeah you seen the temps currently in Atlantic watch out come late July when hurricane uptick. Pretty close to being craziest year for tornadoes since 2011…. May dethrone 2011… wildfires in New Mexico Texas California extreme heat wave lasted over a week and before the summer solstice (very scary) Arizona seeing temps regularly around 120 degrees (this is unheard of in past). I can go on and on. Pretty scary times and equally scary that large portions of United States are still climate change deniers. USA education is no longer anywhere near top spot in world anymore. In fact we are quickly becoming one of the dumbest country’s on earth.!

31. Why are tipping points described as high impact, low likelihood and then later in the video described as inevitable? I worry about Methane pushing us over the threshold of these tipping points and then tipping points cascading tipping other tipping points.
