    Jesus, there's some ignorance on this thread, and the disturbing bit is, from weather geeks! Chomsky is spot on, this administration is potentially one of the most dangerous that's ever been, in regards environmental matters, and it's obvious to!

    So you have evidence that these unprecedented fires are linked to a neutral ENSO?
    Are you taking the piss?

    It's is a well-established fact that a combination of a negative PDO with a positive AMO is a driver of dry conditions in the SW USA. Think back to the Dustbowl almost 100 years ago. The PDO has switched to strongly negative this year aftern being mostly positive in recent years. Add to that neutral to La Niña conditions and you add to this effect. So no, I'm not taking the proverbial.

    As already stated, you would never have seen photos and videos of those events right as they happened. You would never have even known about them.

    So provide the evidence then that this has nothing to do with what I said above.

    Seriously couldn't be bothered, and I really don't have a clue what you're on about anyway, I've done my environmental research, I've moved on from it, I've moved onto the complexities of what has actually caused all these issues, particularly economically, politically and socially, I'm done with the environmental arguments, I've accepted we re wrecking the planet

    The PDO is a description of conditions, it’s not a driver
    It’s like calling steam from a Kettle ‘local sudden evaporation’ and then denying that the kettle causes the steam because ‘local sudden evaporation’ is often correlated with steam

    The dust bowl era was not a purely natural phenomenon, it was a consequence of human activity
    The natural drought would not have had such severe consequences if human agricultural practices didn’t destroy the topsoil

    Similarly natural drought cycles on top of the climate change we have caused creates the unprecedented wildfires we are almost getting used to seeing all year round in recent years

    Cameras were invented in 1816, we’ve had 200 years to take pictures of the ‘natural’ wildfires that are nothing unusual allegedly

    And we have had painting since cavemen, and writing since the sumarians. The images from California would have been recorded in paintings, stories and writing if they happened naturally


  • Registered Users Posts: 22,236 ✭✭✭✭Akrasia


    Oh and wildfires have been getting worse for years now, regardless of where ENSO is or how negative the PDO is. If wildfires are exacerbated by a combination of La Niña and negative PDO then why were they so bad in recent years when there was a weak El Niño and no negative PDO?

    Ok, let me rephrase it then :rolleyes: The conditions that lead to a negative PDO index are likely to cause drought conditions. There, I hope it's clearer now.

    https://www.google.ie/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwiS2oLZ0uDrAhXDxoUKHVOKCwsQFjACegQIARAB&url=https%3A%2F%2Fwww.mdpi.com%2F2073-4433%2F10%2F2%2F82%2Fpdf&usg=AOvVaw0Ih6PBPo_V0NTu8ja8KRGu
    Abstract: In this paper, we applied the Empirical Orthogonal Function (EOF) analysis on a drought index expressed as consecutive dry days (CDD) to identify the drought variability in western United States. Based on the EOF analysis, correlation maps were generated between the leading principle component (PC) of seasonal CDD and sea surface temperature (SST) anomalies to explore the dynamic context of the leading modes in CDD. The EOF analysis indicates that the spatiotemporal pattern of winter CDD is related to an integrated impact from El Niño–Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO), and Atlantic Multi-decadal Oscillation (AMO), while summer CDD is mainly controlled by PDO phases. We also calculated seasonal CDD anomalies during selected climatic phases to further evaluate the impacts of large-scale oceanic oscillation on the spatial pattern of droughts. We found that AMO+/PDO− will contribute to a consistent drought condition during the winter in the western United States. El Niño will bring a dry winter to the northern part of western United States while La Niña will bring a dry winter to the southern part. During El Niño years, the drought center changes with the type of El Niño events. Considering the future states of the examined ocean oscillations, we suggest possible drier than normal conditions in the western
    United States for upcoming decades, and moreover, an intensified drought for the coast areas of the north Pacific region and upper Mississippi River Basin.
    The dust bowl era was not a purely natural phenomenon, it was a consequence of human activity
    The natural drought would not have had such severe consequences if human agricultural practices didn’t destroy the topsoil

    Similarly natural drought cycles on top of the climate change we have caused creates the unprecedented wildfires we are almost getting used to seeing all year round in recent years

    Cameras were invented in 1816, we’ve had 200 years to take pictures of the ‘natural’ wildfires that are nothing unusual allegedly

    And we have had painting since cavemen, and writing since the sumarians. The images from California would have been recorded in paintings, stories and writing if they happened naturally

    Maybe people hadn't been conditioned to treat weather as an impending signal of doom and just accepted it for what it was. And to compare evidence from cameras of 100-200 years ago or cave paintings to the millions of smartphones in daily use now is more than a little laughable.

    ive spent a couple years studying this stuff, ive realised since childhood, we re damaging this planet, ive matured and accepted our reality, deniers will probably never accept this reality, so it is simply wasting my time, i have moved onto trying to figure out how humanity has gotten to this point, i do believe i have found the reasons why, it is now time to react

    San Franciso and the the state of California didn't even exist then:rolleyes: In the meantime the population has gone from a few thousand to 30 million with most of the natural wetlands and groundwater sources lost. But the likes of you claim its all down to "climate change" - newsflash fire is a natural part of the climate there, as is severe droughts including one that wiped out Indian cultures in nearby areas around the Middle Ages.

    Or maybe people aren’t blinded by their own sense of self importance and take the overwhelming majority of expert scientific findings seriously.

    Increases in heatwaves droughts and wildfires were predicted in the models. Now the predictions are coming true, record breaking wildfires all around the world starting earlier and finishing later each year and you just pretend it’s all normal naturally occurring weather

    You’re saying it’s neutral ENSO and negative PDO this year, what about last year where we had El Niño and positive PDO and still saw these massive wildfires raging out of control?


  • Registered Users Posts: 1,492 ✭✭✭Hooter23


    Less than 100 people died from extreme heat and cold in america in 2019...meanwhile in 2018 there were 36,560 deaths from car accidents...I think there are alot more things to worry about than a few degrees difference in temperature...keep paying your carbon tax anyway im sure that will fix the problem

    Are you denying all the expert scientific findings that link certain natural teleconnections with certain types of weather? Wanderer certainly does as he "couldn't be bothered" learning about it. I hope you're not the same.

    There have always been fires in California. After all, it's on the edge of a great big desert. Positive PDO years do not eliminate the probability of fireweather, just reduces it. Just like we got a dry Spring sandwiched in between two very wet periods this year. Is that also down to ghc? I'm sure you'll try to claim that it is, the same way the Clifden and Cork floods were.

    I can imagine you sitting at home searching the net for weather headlines, chomping at the bit to come in with your hyperbole every time there's a drought/flood/heatwave/snowstorm/hurricane/record high pressure....

    This is common place now or at least it's more visible as there are more areas for people to share their thoughts, were people have accepted a fact to be indisputable, then use opinion to validate their beliefs.

    I've posted here about it before. News is 24hrs, Social media 24hrs. Billions of people have a device that can share their stories and experiences.

    We are bombarded with everything and anything that will sell a newspaper, get a view or a link clicked. If it fits a narrative it gets pumped out. Whether Left or Right, AGW supporting or not, Global outlets media have little to no accountability.

    Regarding California, they closed down their Nuclear plants, opted instead to buy in power from other states. So they look green, but in fact they just shift their carbon footprint else where. Their green energy has cost them billions which is now a tax payer burden, which is disproportionate to the lower classes. It's also failed!

    I visited family in Kangroo Valley back in early Feb (Just as Covid hit), which was scorched by Australia fires. The residents blamed the problem on local authorities refusing to have controlled burns. They cited that aboriginals have been lighting controlled fires for 50,000 years, yet now we stop?
    I know that is anecdotal, but it's a first hand experience I had with the people impacted. They weren't screaming about CO2 or AGW.

    Oregon and CA are very much the same, CA refrains from controlled burns.
    Which is mind boggling considering they have no problem draining wetlands and otherwise destroying habitats, but refrain from controlled burns???

    The heat wave is weather... Not climate???
    I see a lot of cold spells dismissed as 'Weather cherry picking'. Is a heat wave not the same?

    Maybe it's time to look local. What has changed in CA over the past 100 years?
    Correlate that impact on their local weather.

    The warmest years ever recorded globally have all occurred since 1998, with the top ten being 2016, 2019, 2015, 2017, 2018, 2014, 2010, 2013 and 2005 in that order. 2020 looks like its on course to be the hottest ever just like the climate models predicted, so no, its not a case of cherry picking the hot stuff, the world is being heated to scary levels by our greenhouse gas emissions just like all the climate models predict so carry on dismissing it as weather if it makes you feel better.

    Akrasia today was quick to correctly point out that human mismanagement of the land back in the 1930s contributed to the severity of the effects, yet he will not acknowledge that similar activities are happening in many prone parts of the world today. No, today it's all down to driving cars.

    I was just commenting on another thread now about Lewis Hamilton's new team in the fledgling Extreme-E racing championship starting next year. They say the objective of the championship is to highlight the climate emergency by racing at locations that are being "decimated" by climate disasters. Starting in Senegal, then Saudi Arabia, Nepal, Greeland and finally Brazil. They claim they will generate 20,000 tonnes of carbon footprint but aim to be carbon-neutral by the end of it. Deliberately generating 20,000 tonnes in order to negate it? Some logic alright. A publicity stunt gone to a new level of madness.

    But how can you ignore science and deliberately not even try to understand it? The same IPCC will readily agree that teleconnections have always had a strong correlation with certain weather events. Nobody is disputing that except yourself and Akrasia. Maybe your man Oriel36 had a point after all, I hate to say.

    2019-year-to-date-top-10-warmest-years-NOAA_0.png

    2017, 2018 and 2019 colder than 2016.
    So what ever we did in those 3 years we can repeat? Cause it worked to bring down temperatures? Am I doing this right? ;)
    If CO2 is constantly rising, why are we not seeing a year on year compound increase. More CO2 = More heat retention, except for 2017-2019 where more CO2 = Less heat? Surely based on AGW theory it should be in order of hottest 2019, 2018, 2017 ect..
    If not, there must be another factor we are missing or don't understand. Or our instruments of measure aren't as accurate as we think.

    It's worth noting tho.
    The sparse records we do have from the ~1880s to 1970s have been adjusted.
    Any temperature recording before that are extrapolated and estimated from ice cores and and decaying plant animals remains ect.

    Extrapolation and interpretations, it's really open to interference.

    Edit: When I say sparse records, I mean in terms of global coverage. Not how often records were maintained in a particular site.

    That's not scientific at all, that's fate based.

It's important to note, some criticism of ipcc findings believes, that projected models are extremely conservative, which is deeply alarming, if true, and those critics make extremely good arguments for their concerns

    Yes, I've realised since childhood that there was serious problems with the way we were treating the planet, I've spent my life gathering knowledge on the matter, confirming this, realising it is in fact our economic activities that are incompatible with maintaining an element of balance on this planet, noting, it may not be possible to have no negative impacts on the planet while we exist here, but believing we have over extended ourselves, and extinction of many species, including ourselves, is now very possible.

    Politics needs to be removed from the science.
    Big name preachers of AGW are buying seafront property:confused:
    Flying around the globe, shaming others for driving their cars to work.

    The predicted extremes are so varying that any change we make today can't be measured in the future.
    If the predictions are as bad as they say, well there is nothing we can do about it, maybe go back to stone age technology?

    Global warming is only something that peoples and countries of wealth can be concerned about. It requires that people in poverty remain in poverty so as not to increase their energy needs. Then the wealthier move to technology and energy inputs not accessible to the poor. it's a societal disaster pushed in a large part by socialists (go figure). It's all pinned on a prediction that warmer weather means the demise of humans, and that ice core interpretations have shown that climate varies only fraction's of degrees over millennia. It reads like a B movie on the Sci-Fi channel.

    There are more concerning matters, like starvation and abject poverty that we need to fix first.

    The folks who are are pushing for change do very little to act out what they preach, usually defaulting to "well the government need too..."
    Those people should be giving up their modern luxuries, but they don't, they stand on their pedestal virtue signalling to everyone else.

    There have always been fires in California. After all, it's on the edge of a great big desert. Positive PDO years do not eliminate the probability of fireweather, just reduces it. Just like we got a dry Spring sandwiched in between two very wet periods this year. Is that also down to ghc? I'm sure you'll try to claim that it is, the same way the Clifden and Cork floods were.

    You have an active imagination and you’re welcome to it.

    I am not denying that there are weather patterns that have been linked to oscillating flows of energy between the different energy basins in our oceans and atmosphere, that would be silly, almost as silly as discounting the fact that the AGW has caused quadrillions of additional joules of energy to become trapped in our biosphere and these must, by definition, affect global weather patterns

    All weather now occurs in a system with more energy encapsulated in it

    Because not all the energy is retained in the ocean surface and atmosphere. 90% of the extra energy gets absorbed in the oceans

    There are natural processes that sequester some of this heat in the deep ocean, and others that release sequestered heat to the surface again, these currents and oscillations impact on natural variability but the energy imbalance also affects these systems.

    There is a worry that the safety valve of deep water heat sequestration is slowing down in its ability to mitigate climate change.

    Global warming is only something that peoples and countries of wealth can be concerned about. It requires that people in poverty remain in poverty so as not to increase their energy needs. Then the wealthier move to technology and energy inputs not accessible to the poor. it's a societal disaster pushed in a large part by socialists (go figure). It's all pinned on a prediction that warmer weather means the demise of humans, and that ice core interpretations have shown that climate varies only fraction's of degrees over millennia. It reads like a B movie on the Sci-Fi channel.
    Global average temperatures have increased by 1c already. Way beyond natural variability and we know what is causing it

    You say poor countries don’t care about climate change? That’s a load of nonsense. It’s like saying a poor pensioner doesn’t care about the hole in her roof and her broken window. It’s not that she doesn’t care, it’s that she can’t afford to do the repairs she needs to prevent more damage from accumulating until her house becomes uninhabitable
    Wealthy nations need to make climate action a priority and support the global drive to Transition to carbon neutral economies, for our own sake as much as the benefit of the developing world
