Hottest Evah September!!

The latest of many heat records broken this year is putting the world on course for its hottest year ever, and is a sign of what is to come in future, according to scientists.

Last month was not only the hottest September on record, new data has confirmed, but it was higher by a margin described by stunned scientists as "extraordinary", "huge" and "whopping".

https://news.sky.com/story/september-2023-was-worlds-hottest-september-on-record-by-extraordinary-margin-new-data-confirms-with-scientists-blaming-more-than-climate-change-12976750

I’ll ignore the ignorance of journalists who think that the world started in the 19thC, during the Little Ice Age. And the fact that a “global average temperature” is a meaningless construct, which assumes you can average completely different things.

According to satellite data, the temperature anomaly last month was 0.24C higher than the previous peak in 2016:

https://www.drroyspencer.com/latest-global-temperatures/

The idea that GHGs can make such a difference in such a short period of time is utterly absurd. But the Sky report does give us a clue:

Piers Forster – the interim chair of the government’s Climate Change Committee but speaking in his capacity as climate change professor at Leeds University – said variations between months each year are usually quite small.

"Therefore, breaking the previous September record by a whopping 0.5C is crazy and shows something really bizarre is going on in the oceans," he said.

Greenhouse gases have been warming not just the atmosphere but also the deep ocean, especially in the Atlantic, added Prof Forster, and now a change in ocean circulation is "causing some of that heat from the deeper ocean to resurface and bite us".

Forster is quite wrong, knowingly I suspect, because it is physically impossible for GHGs to warm the deep ocean. This is because infrared radiation can only penetrate the top few millimeters of the sea.

However, oceans are an enormous heat store, and a change in ocean circulation, as implied by Forster, can have large effects on atmospheric temperatures.

After all, swings from La Nina to El Nino can often increase global temperatures by a full degree, and that is just a result of ocean circulation is a small part of the Pacific.

And that heat is supplied by the sun, not carbon dioxide.

Why then is there no scientific research going on into what is happening in the oceans and why? Is it more convenient just to blame climate change?

There has also been absolutely no mention in any of these reports of the underwater Hunga Tonga volcano, which erupted in January last year, blasting an enormous plume of water vapor into Earth’s stratosphere.

Water vapour, as we know, is by far the most powerful GHG, responsible for about half of the Earth’s greenhouse effect. The eruption was so powerful that the plume reached the stratosphere, where it can only very slowly return to the Earth’s surface, unlike water vapour in the troposphere.

For the months after the eruption this greenhouse effect was countered by the cooling effect of the ash and aerosols sent aloft. Now that this effect has receded, we are seeing the full greenhouse effect of the plume.

One study last year found that:

This extra water vapor could influence atmospheric chemistry, boosting certain chemical reactions that could temporarily worsen depletion of the ozone layer. It could also influence surface temperatures. Massive volcanic eruptions like Krakatoa and Mount Pinatubo typically cool Earth’s surface by ejecting gases, dust, and ash that reflect sunlight back into space. In contrast, the Tonga volcano didn’t inject large amounts of aerosols into the stratosphere, and the huge amounts of water vapor from the eruption may have a small, temporary warming effect, since water vapor traps heat. The effect would dissipate when the extra water vapor cycles out of the stratosphere and would not be enough to noticeably exacerbate climate change effects.

https://notalotofpeopleknowthat.wordpress.com/2023/08/17/hunga-tonga-its-role-in-rising-global-temperatures/

They calculated that the radiative forcing from this plume of water vapour was about two thirds of the CO2 growth between 1996 and 2005.

How much of the recent spike in temperatures is due to Hunga Tonga is debatable.

But what I find remarkable about this, if unsurprising, is how there has been virtually no public discussion of this, or serious scientific research into it. Instead climate scientists seem to want to brush it under the carpet, and blame rising temperatures on “climate change”.

    I suspect the reason Paul is that if such eruptions are a significant cause of warming then the massive vested interests, who have such influence in the climate scare narrative, would be exposed as fraudulent. That would never do would it.

    No doubt it is nigh on impossible to get funding to carry out research that might uncover information a huge number of people would rather be kept secret or unknown. I have hopes that the new Indian solar orbiter will provide some good information given that Indian scientists have not sold their souls to the devil that is global warming activism.

        The reason why the nights are so much colder than in the daytime is written into your text – the dry air. Just goes to show that water vapour is by far the most important greenhouse gas. My guess would also be that you are now having still, clear nights.

      The UAH satellite data takes measurements from pretty much the whole of the troposphere, so should be relatively uncontaminated by UHI. I’m convinced it’s the most accurate global temperature data set and the massive spike in temperature anomalies over the past 4 months is genuine. The switch from La Nina to El Nino is probably partly responsible, but most of the increase is almost certainly due to Hunga Tonga. How long it will last for and how high the spike will go is anyone’s guess, but I wouldn’t be surprised to see a further rise of 0.3-0.5 degrees before the end of the year probably followed by a drop of roughly 1 degree before the end of 2024.

    ‘It keeps the world on course for its hottest year ever – expected to be 1.4C warmer than before the industrial era.

    The new record is just the latest to be shattered this year – with new highs set in June, July and August.

    Scientists are pointing the finger primarily at climate change, and warned of worse to come.’

    Giving ‘climate change’ the finger.

    So just what exactly is this ‘climate change?’

    “Climate change refers to long-term shifts in temperatures and weather patterns.” — UN

    So the hottest September EVAH was caused by a shift in temperatures.

    One other thing that is not mentioned by the Met Office or the MSM are the words “an Indian summer”. A bit of good weather in autumn is now climate change, as if we never had Indian summers in the past.

      Hi Phillip, todays brainwashing from the Met Office/BBC.
      https://www.bbc.co.uk/news/uk-67028073
      “A temperature of 25C has only been reached or exceeded in three other years in the past quarter of a century – in 2018, 2011 and 2001.”
      So temperature records are now only over 25 years? Pity it was 26.7°C on the 7th October at Southend in 1921 but of course over 100 yearold recordings
      cannot possibly count.
      Followed by “However, the all-time October record of 29.9C, set on 1 October 2011 in Gravesend, is unlikely to be reached.”
      Well that’s because the station was removed 7 years ago as being located next to the cooling fans of the main Thames Pilot Radar relay station (it really was!) was not an acceptable location.

      And then, of course,
      “Unseasonal warm weather is likely to become more common due to climate change, which is having an increasing impact on all parts of the UK.”
      YOU MUST BELIEVE!

      • Phoenix44 permalink

        And in what way is this unseasonal warmth bad? In SW France it’s very warm and nature appears to be loving it. Butterflies are still around, the wasps and bees are active, weeds and grass keep growing, the whip snakes and lizards are still zipping about. Warm is good.

      Also known for centuries as “St Luke’s Summer”, Phillip; his feast day being October 18th. There are several ‘spasms’ through the year when we can expect unseasonal temperatures, named after some meteorologist whose name escapes me. Christmas tends to be another, white Christmasses being an exception.
      But Jamaica, according to my sister-in-law who lived there for several years, is about the only place in the world where you can more or less set your clock by a weather event, the daily (more often than not) thunderstorm turning up pretty regularly at 2pm! I imagine there are other similar occurrences elsewhere in the tropics where everything appears to be more predictable than in the temperate latitudes.
      But it’s all still only weather!

    The ppm of carbon dioxide has not jumped up at all. Although Mauna Loa volcano erupted and they had to move out. The reason the climate change scientists are ignoring Hunga Tonga is simple. It shows that Carbon dioxide is not the reason that temperature is increasing, it is water vapour. They are going to be proven as either incompetent or liars. More likely both.

    October 6, 2023 6:05 pm

    The UAH satellite record is certainly showing a most rapid rise over the last three months. Whatever the reason, one thing it assuredly is not is CO2, as the miniscule rise in the gas over that period could not conceivably be the cause.
    The Hunga-Tonga eruption combined with el Nino does look the most likely explanation.

    I have seldom read such rubbish from a so-called climate scientist. That the ocean at depth has warmer water than at the surface? Obviously oceanography was something that was not included in his studies. Or perhaps the journalist involved in making the report has not understood either, and has not quoted accurately.
    But on the other side, Paul states that climate change cannot warm the oceans because I/R radiation only penetrates the oceans a few millimetres. What about ocean mixing? the wind?
    What has struck me with the warm North Atlantic this summer is the coupling to high pressure and the associated lack of wind.
    What appears to be missing from the proposed causes for the extra global warmth is the effect of the wind on evaporation from the oceans. With lower average wind speeds the oceans will cool less via evaporation.
    What also seems to be missing from the climate debate is that average global wind speeds are thought to have been dropping since the 1980s. I wonder if wind speed has been included in the computer programs?

    [[Forster is quite wrong, knowingly I suspect, because it is physically impossible for GHGs to warm the deep ocean. This is because infrared radiation can only penetrate the top few millimeters of the sea.]]

    Hit the nail on the head. It’s the Sun’s downward visual wavelength radiation that heats the sea, not downward IR. The sea continually cools via black body IR upward radiation, conduction/convection, and evaporation.

    The big haha is that no IR from greenhouse gases can heat the Earth’s surface, land or sea, because it’s not an independent source of energy, just delayed and regurgitated surface cooling IR that is at the tail end of the IR cooling curve, meaning that all the real surface heat radiated at light speed to outer space, permanently cooling the surface until more sunlight is received.

    Any dinky downward IR will be completely absorbed by the surface because it’s a black body that absorbs all wavelengths, but it just merges into the internal energy distribution and gets emitted along the surface’s black body radiation curve whose peak power wavelength and intensity are dependent only on its instantaneous absolute temperature. It’s no different than a water hose feeding off a water tank and putting out a fire on a building in the distance. Any small backspray can’t make the tank level go higher. The U.N. IPCC octopus is double-counting energy to push its big hoax.

    Greenhouse gas back radiation subtracts from downward solar radiation, not adds to it. In other words, long wavelength low energy intensity 15 micron CO2 back radiation was already emitted by the surface as part of its cooling process, and can’t reheat the surface one iota because it just gets recycled and emitted at shorter wavelengths as a dinky contribution to the ongoing total IR cooling emission power.

    If the instantaneous IR cooling radiation drained 1 Joule of energy in the first instant, and the CO2 downward IR radiation returned .01 or even .1 Joule in the second instant, the heat capacity of so many degrees C or K per Joule would lower the surface temperature in the first instant, and in the second instant the downward IR would be swamped out with the lower wavelength emissions during the second instant and couldn’t restore the lost temperature one iota, that is, lower the peak power wavelength and increase its intensity to make the temperature higher than before the first instant. Surface temperature just keeps dropping smoothly with the CO2 radiation having no effect on the instantaneous temperature.

    Another big haha. If the surface had a notch in its blackbody radiation emission curve at the greenhouse gas absorption/emission wavelength, which would be equivalent to 100% of the energy returned, it wouldn’t have any effect on surface temperature. Only total solar energy absorbed would determine that.

    There is a cartoon in the Guardian today about September Anomaly, what to describe it as… gobsmacking bananas, button clenching nutso, pants crappingly bonkers,
    about 280 comments all from green loonies although a few had been moderated ie removed. |So I put this on.

    Not one mention of the Hunga Tonga Oceanic Volcano that erupted in January 2022, it threw vast quantities of water vapour and ash and aerosols very high 31 miles in fact, the water vapour is still up there, the other more solid aerosols has dropped down.
    It is the water vapour that is causing the higher anomaly, after all it is a better greenhouse gas than carbon dioxide.
    It is impossible for the carbon dioxide model to give this rapid increase, any way carbon dioxide is not showing a peaking.

    I am now MODERATED,,,as I tried to reply to the 3 comments on my comment. Here is the situation now tho I aint been deleted yet
