    To be fair the uniformed opinions come from both sides. Some of it's hilarious.. from both sides

    Never argue with an idiot. They will only bring you down to their level and beat you with experience.

    Inaccurate data is a problem if it never gets corrected.

    Provisional data taking time to be validated is not a problem

    What is a problem, is the Climate change denier strategy of promoting 'Fear, Uncertainty and Doubt'

    Fear - 'If we act to prevent climate change, we'll be suffocated by taxes'

    Uncertainty - 'We cannot trust any of the science, there are too many variables, the climate is always changing, who's to say this isn't natural'

    Doubt - 'All experts are compromised, so I'll just not believe anyone'

    And your next line '

    "Anyway, I agree the climate is changing, I don't think anyone can deny that. It's always changed"

    This is literally straight from the Climate change deniers, the top 1, or the top 10 list of denier talking points

    I'm not saying it's anything malicious on your part. But you're a victim of a concerted campaign to control the discourse so that the b*stards at the G20 can have yet another conference where they agree, yet again, to do nothing to stop fossil fuels from poisoning the planet.

    https://www.theguardian.com/world/2023/jul/22/g20-countries-fail-to-reach-agreement-on-cutting-fossil-fuels

    Because whatever you think about 'the greens' trying to control the discourse or politics, it's all run by the Fossil Fuel lobby who own the politicians and everyone who makes all of the most important decisions about what happens to our planet.

    First they denied that the climate was changing, then they deny that the change is unnatural

    then they say maybe it is natural, maybe some is man made, who is to say what part of it is caused by humans


    The truth is, we know unequivocally, all of the observed warming is caused by humans.

    All of it.

    If it wasn't for human impacts, the planet would currently be in a slight cooling phase.

    No they aren't. Your Twitter threads are lying to you

    I have 10 cars each more fuel inefficient than the last

    None of those 10 gas guzzling oil spewing diesel particulate emitting vehicles make anywhere near as much of a difference to the global climate as my choice to support politicians and policies that will support sustainable development and vote in favour of regulating fossil fuels companies and promoting renewable energy

    If you vote Tory in the UK, or Republican in the US, or if you vote 'anti green' in ireland, then it doesn't matter if you grow all your own turnips and extract capture the carbon from your own farts, it is meaningless because this is a global problem that requires global political action to solve.

    There is no reason to believe this. No evidence or any model suggests that Earth would become unlivable.

    Is that really your bar for whether climate change is a problem? That some small bands of humans can survive in a post apocalyptic wasteland....

    There are plausible climate scenarios where the earth experiences runaway climate change and the planet flips to a 'hothouse earth' phase Where global average temperatures increase by more than 5c with sea levels 60 metres higher than they are today

    https://www.pnas.org/doi/10.1073/pnas.1810141115


    Most of the planet where most of the people live now would be totally uninhabitable either through high temperatures or being under water. I suppose some survivors could rebuild something approaching a civilisation where the arctic used to be.

    I mean, that is a price worth paying so we don't have to pay a negligable amount of money in carbon taxes and build better public transport infrastructure

    60 m seas level rise would not cause extinction. But that is serious sea level rise and very disruptive. However you need far more increase in temp than 5°C to cause that. 5°C would only cause a few metres rise. Less than 10 metres.



  • Registered Users, Registered Users 2 Posts: 2,217 ✭✭✭Jizique


    Would nearly be worth it to see George Lee salivating as he breathlessly reported on the unfolding developments



  • Registered Users, Registered Users 2 Posts: 23,448 ✭✭✭✭Akrasia


    Actually, sustained temperature increases of more than 2-3c above pre-industrial levels would be enough to set in motion the terminal loss of antarctic ice sheets which is 60 metres of sea level rises with most of the increases happening abruptly over the next 500-1000 years over the course of the next 1000 or so years.

    It doesn't really matter TBH, none of us will be here to see it, but it would be an appalling legacy that would directly impact our children and their children, condemning them to a future of ever worsening living conditions crammed into a smaller and less productive world.

    Go us.

    I'd much rather see that at the cinema than in real life.

    It will become unlivable for us. The earth has already been through 6 mass extinctions with the worst killing 95% of all species. Life is hardy and persistent - but humans are only adapted to live in a very narrow range of conditions and we are pushing things outside that very narrow band.

    ERA5 provides hourly estimates for a large number of atmospheric, ocean-wave and land-surface quantities. An uncertainty estimate is sampled by an underlying 10-member ensemble at three-hourly intervals. Ensemble mean and spread have been pre-computed for convenience. Such uncertainty estimates are closely related to the information content of the available observing system which has evolved considerably over time. They also indicate flow-dependent sensitive areas. To facilitate many climate applications, monthly-mean averages have been pre-calculated too, though monthly means are not available for the ensemble mean and spread.

    That is from ERA5 hourly data on single levels from 1940 to present (copernicus.eu) the source of the data in your claim.

    Since estimates are being used, this is NOT science.

    Do you understand how it was calculated and why interpolation is a valid technique ?



  • Registered Users, Registered Users 2 Posts: 412 ✭✭bluedex


    So the #1 tactic of climate change deniers is to agree that climate is changing? Lol 🤣

    Never argue with an idiot. They will only bring you down to their level and beat you with experience.



  • Registered Users, Registered Users 2 Posts: 2,098 ✭✭✭randomname2005


    Yes, say it is changing but humans have nothing to do with it, all purely natural.



  • Registered Users, Registered Users 2 Posts: 12,156 ✭✭✭✭tom1ie


    Nah- AMOC will collapse and actually cover the northern hemisphere in ice- remember- we had this discussion earlier.

    When the northern hemisphere is covered in ice, that ice will reflect the sun and hence the heat out into space this cooling the overall planet and returning us to beautiful equilibrium 😂



  • Registered Users, Registered Users 2 Posts: 12,156 ✭✭✭✭tom1ie


    But AMOC collapsing covers us in the northern hemisphere in ICE thus cooling the planet- no?

    That’s the latest scaremongering hot off the press anyway from you greenies isn’t it?



  • Registered Users, Registered Users 2 Posts: 3,008 ✭✭✭.Donegal.


    One report from danish scientists = greenies. Ok. Also sorry to hear it scared you. That’s just awful.



  • Registered Users, Registered Users 2 Posts: 12,156 ✭✭✭✭tom1ie


    Nah didn’t scare me.

    Been hearing about AMOC collapsing since the 60s actually.

    Also 2004 blockbuster the day after tomorrow was based on it too.

    But carry on with your scenario regardless.



  • Registered Users, Registered Users 2 Posts: 2,714 ✭✭✭Yellow_Fern


    Unlivable based on what model? Show me the scenarios? Show me data that shows food yields are decreasing? Show us data that cultivated land is decreasing?

    Thats actually what happened at the end of the last ice age and cause the Young Dryas. This was caused by a massive ice breach from the great lakes area into the North Atlantic which closed down the Gulf stream plunging the North Atlantic back into ice age like conditions. However as we all know this didn't last and the ice quickly retreated after a short time and the Gulf Stream returned. However since we do not have a great ice dam in North America it is very unlikely that this would repeat itself and what we could expect to see is much of Northern Europe becoming tundra before returning to a overall warmer state.

    Its worth noting that global warming is happening at roughly 5x the speed in the high arctic so we are in a very different set of circumstances from what happened at the end of the last ice age.


    So to answer your point - it wouldn't return us to any sort of long term equilibrium - just a very short respite. Meanwhile CO2 would continue to accumulate in the atmosphere and would bring back warming with vengeance.



  • Registered Users, Registered Users 2 Posts: 12,156 ✭✭✭✭tom1ie


    Yeah so in other words Ireland would freeze if AMOC collapsed yes?



  • Registered Users, Registered Users 2 Posts: 412 ✭✭bluedex


    Hilarious. Please quote the part where I said humans have nothing to do with it.

    I'll make it easy for you, human existence on the planet DOES contribute to climate change.

    Never argue with an idiot. They will only bring you down to their level and beat you with experience.



  • Posts: 6,626 ✭✭✭ [Deleted User]


    Climate change is just getting going, we are on the edge of multiple tipping point. The main one been the thawing of the permafrost which will release a massive amount of methane which is 30x more powerful a greenhouse gas. Once that happens the oceans warms dramatically releasing all the half of the carbon dioxdie they have sequestered since we started burning fossil fuels (since carbon dioxide is less soluable in warm water), but already at this point the acidity of the oceans caused by the CO2 added to the oceans will have collapsed the phytoplancton food chain which supplies the majority of our oxygen. The planet literally burns and suffocates at the same time. We will not survive this cascade of events.


    This is all modelled and described in the IPCC reports.



  • Registered Users, Registered Users 2 Posts: 3,008 ✭✭✭.Donegal.


    How’s it my scenario? It was one report by danish scientists. The day after tomorrow also had people instantly freezing to death so I’m not sure what significance it has lol.



  • Registered Users, Registered Users 2 Posts: 12,156 ✭✭✭✭tom1ie


    Lol yourself 😂.

    AMOC collapsing has been talked about for years as I said.

    Hollywood loves embellishing a good scenario but the day after tomorrow is based on AMOC collapsing.



  • Registered Users, Registered Users 2 Posts: 412 ✭✭bluedex


    Oh dear. Let's enjoy the next few weeks in that case.

    You can make a difference - don't bury your head in the sand and continue to eat animals.


    Vegan diet cuts environmental damage massively, study shows

    Reducing amount of meat and dairy foodstuffs we eat can minimise dietary footprint

  • Registered Users, Registered Users 2 Posts: 12,156 ✭✭✭✭tom1ie


    Yeah but in Ireland we would need to buy a heavy coat and thermals as we are due to freeze right?
