back to article Climate models need revising: Droughts, heat waves not such a big deal

So, the world's climate is changing - that's one thing most scientists are indeed agreed on. But what does that actually mean for the future? Could hotter summer temperatures kill off growing plants, leading to runaway atmospheric carbon increases and turning the Earth into a lifeless baking hell? Not so much, according to US …

          We've given up a lot of our adaptability for civilisation and the days when we could just decamp en mass to the next valley are gone. Mass migration now causes civil unrest or even war. If the climate does change severely then I've no doubt we'll survive as a species - just at a much reduced headcount. Which is good news for the planet, not such good news for the billions who might starve to death.

However if desertification of a large part of india, africa, the USA and china (where its already happening) really takes hold then food production will drop, water will become scarce - especially as aquifers continue to be depleted - and people will start to migrate or die. Or does your crystal ball tell you that will never happen Mr Business As Usual? I suspect the former inhabitants of the sahara thought that too.

        The Earth has, several times, survived disasters much larger than anything we puny Humans could ever inflict on it (e.g. the K-T Event).

        The absolute worst we could do is wipe out a sizeable chunk of the current plant and animal species, along with ourselves.

        A couple of million years later (a mere eye-blink in geological time), the Earth will have recovered and will then proceed to get along quite nicely without us.

        In the grand scheme of things we are all pointless and irrelevant. It is only our sheer arrogance that makes us believe we could ever have any long-lasting effect on the Earth.

          Well, uh, that sounds like cause for alarm there, Mr. Cowherd. And it would be a bit of a shame if we inflicted significant damage to our rather unusual ecosystem on our way out.

          There's precious little arrogance involved here, apart from that exhibited by the more foaming-at-the-mouth avengers-of-gaia type.

            I'm not a "foaming-at-the-mouth avengers-of-gaia type". I am simply aware if my insignificance in the grand scheme of time and space. You, I and, indeed, the whole Human race, exist, and will only ever exist, as an infinitely small mote with respect to the vastness of all that has been, and all there is.

            The Earth has, in the past, recovered from a number of massive ecological disasters. Disasters far bigger than anything we Humans could ever inflict on it . It will certainly suffer from them in the future, whether that be from the actions of Humans (or whatever species follows us, or we evolve into), or from massive volcanism or asteroid strike (as has happened in the past).

            Whatever we Humans do here and now will have little bearing on the state of the Earth's ecosystem in 4 or 5 million years time.

              No-one cares what is going to happen in 5 million years time. No-one. The fact people *talk* about "destroying the planet" and similar things is pretty much irrelevant... the topic of conversation is ultimately 'we're going to inflict significant damage to our ecosystem and maybe even jeopardise our place in it', through the lens of someone a little ignorant and hysterical.

              Their sloppy terminology may be irritating, but perhaps you could try thinking about what other people *mean* rather than filtering everything through your own "oh you humans are so arrogant" lens which is frankly rather tedious and definitely unhelpful.

      Re: So...


      THIS PARTICULAR GRASS is resilient. The resilience of other plants/animals was not tested at all by this study.

      The key phrase here is : "If these patterns are general across ecosystems..."

      Note the "IF". This study has shown that one particular ecosystem can withstand heat waves and drought at specific times. THAT IS ALL.

      1. Doug 3

        Re: Re: So...

        and guess what? those grasses are already used to hot dry August months so what we're really talking about is a bit more heat. Wow, big surprise their slow growth or no growth period isn't effected by a little more heat.

        I almost LOL'ed when I saw that "if" statement.

    3. Doug 3

      Re: So... subset of all plants

      it was about a small subset of plants, those found in prairie grasslands and not "plants" in general.

      And whats also strange about these "boffins" leap to conclusion is that it was about heat waves in a single month, August.

      Now I don't know about prairie grass but another plant in the grass family is bamboo and it goes through cycles of root growth, nutritional accumulation and greenery growth. So one would hope that these boffins would know what growth cycle their grasses are in and how prolonged hot weather for that month would effect that cycle.

      And off the top of the head guess is it would have little effect since August is already a dry hot month so getting hotter isn't going to mess with the plant growth cycle much if any. Now throw in things like early recovery from dormancy because of consistently mild winters and early spring and you might start seeing changes in the grasslands. Possibly a change in which varieties of plants are at what ratio.

      It sure seems like quite a jump to go from 'wow, heat waves in August don't effect grasses and we thought they would.' to 'everyone should rethink climate change.'.

  2. fero

    The report does NOT say "Droughts, heatwaves not such a big deal". What it does say is that the effect depends upon what time of year the droughts and heatwaves hit, and recommends that climate models are improved to show seasonal variations. This also implies having better localised climate models and merging with ecosystem models.

    "The absolute worst we could do is wipe out a sizeable chunk of the current plant and animal species, along with ourselves."

    As worst-case scenarios go, that's actually pretty bad. Maybe I'm biased here, but I do have a fairly strong preference for NOT getting wiped out, with or without other species...

    A falling population would probably be a good thing in several respects - not via genocide of course, but birthrates are already below replacement in bits of Europe, meaning the population would already be dropping there but for immigration from other regions. Dropping back to the one billion mark by 2100 would be nice.

    Throughout, history societies always have pet worries. Take the British for example, there were times everyone worried or was paranoid about Spain, and France (probably still so), and Germany etc. Since WWII, the world's has had MAD--Mutually Assured Destruction from nuclear war, and the Cold War; and the US and Australia etc. had the Red Peril and the Domino Effect--hence the Vietnam War. Nowadays, it's climate change, fear of pedophiles, refugees, Islam, fear of chemicals and so on.

    Fear in society is like a meme that fattens up as it spreads, thus exaggeration is rife even amongst professionals. Even without exaggerating any data or distorting facts, professionals also can over emphasise, thus they opt for society's status quo, sometimes without realizing it. Of course, the meme is self-feeding especially when the notion it conveys acquires politically correct status (as climate science has done).

    What I find most irritating about the climate debate and climate science, is that it's now almost become a 'religion' especially so with environmentalists whether they be climate scientists or otherwise. Thus, inevitably, the debate has become extremely polarised.

    I grew up in a time when the ethos of Dalton's Scientific Method was much stronger than it is today; then one took for granted that what a researchers wrote in scientific and engineering journals was the science as they saw it--whether the facts were right or wrong! Today, I read these journals with considerable suspicion wondering what the underlying agendas are or what commercial organisation is funding the research.

    I genuinely miss those more naive times. Sure, not all was well then either, but the debates were a lot more genuine and much less cynical.

    1. Gordon 10 Silver badge

      Nice post

      However I'm not sure the scientific method ever has been or ever will be applicable to these 'fear memes' indeed that maybe one of their defining characteristics.

        @Gordon 10

        "However I'm not sure the scientific method ever has been or ever will be applicable to these 'fear memes' indeed that maybe one of their defining characteristics"

        Agree. I find there's something peculiarly 'spongy' about the climate debate. It's nothing to do with the outcomes (global warming, cooling, whatever)--that's another matter, rather it's how poorly the argument is conducted.

        Whether they're right or wrong, today, we've climate scientists who are often excessively emotional who then present small-sample data that only shows statistical trends as an unarguable 'almost-certainty' (it's a double whammy weakening of argument in my pinion). Then there's the non-scientific profits of doom who latch onto shreds of often-irrelevant evidence then present them as gospel; then we've the 'confused middle' who're sick of the acrimonious debate, and of course a whole range of deniers from those with facts to outright BS artists. To me, it's boring noise rather than formal augment.

        I was at high school in the first half of the '60s and EVEN in my first year, physics and chemistry teachers wouldn't have put up with such woolly thinking from us kids! It was always observation/theory-aim-method-experiment-results-conclusion stuff which also included statistical error (n, root-n, residuals), etc. It also included obligatory instrument calibration together with environment data, temperature, humidity, mains voltage etc. To us kids, the experimental procedure and documentation thereof became so automatic that it was eventually perfunctory (lab notebook records were a substantial part of the final marks). By university, scientific procedure had become an a priori concept.

        Moreover, technical and even tech hobby magazines had a similar rigorous ethos. Also debates back then had subjects and predicates and apples were compared to apples and not oranges.

    The difference between "simple" and "simplistic" models

    Simplistic models have few variables and *appear* to explain the facts. Places have seasons, if they have a drought and/or heatwave in the wrong season bad things happen.

    Except they don't stand *scrutiny*.

    In some ways the new model is still "simple" but of course it depends if this applies to the *same* 2 week periods in other parts of the world.

    a nice object lesson in what happens when you trust "simple" models that turn out to be "simplistic" instead.

    Is it just me or does the amount of *real* science involved in climate modelling appear to be rising?

    Thumbs up for good science. Let's see a few more of the assumptions underlying climate models checked. It's better to *know* than to assume.

    BTW I don't think climate models talk in terms of "seasons." It's just certain parameters (sunlight, rainfall, green coverage) vary in a systematic way at different times in the year.

            I was aware of this and have been aware of this for some decades.

            The questions were

            a) How much of that work had been *incorporated* into the various global circulation models of climate.

            b)How vigorously has modellers looked for gaps in their models and updated their models accordingly.

            I recall a Byte article in the early 80's about the Forth computer language in which (IIRC) a chemist was saying how cloud models were poor and Forth let him experiment with the necessary parameters very quickly.

            A *decade* later I saw reports of climate modellers saying their models still did not *quite* account for how the real world behaved.

            This effects of sunspots (or large solar plasma emissions) have been dismissed for decades and it seems only in the *very* recent past that modellers have admitted that *maybe* there might be some effect. CLOUD could have been performed any time in the last 20 (if not 30) years.

            Such a poor attitude to investigating any *systematic* flaws in their models does them no credit especially when their conclusions (CO2 is too high and you must reduce it now) will cost *billions* of dollars/euros/pounds/ to implement (and will be irrelevant if the US/China and India don't agree).

            that's not "science" as I understand the term.

              re a & b - As this research is done at PHd and post-Doc research level, I'd imagine that the research is pretty vigorous. It is being incorporated as quickly as possible, given funding restrictions and requirements for associated research to complete before more research can carry on - You can't include an experiment in your models before it's been finished and written up.

              Byte isn't exactly a peer reviewed science journal.

              As for models being poor in the 80s and now. What would you say if a meteorologist said that they had finished a model and that no further work was needed on it?

              Few people (in the know) seem convinced that Sun spots have any significant effect on weather or climate, this tends to mean that if there is an effect it is small, therefore better to focus on areas where it is known that research is needed and can be of benefit. Not everything can be researched at the same time, it simply costs too much and there aren't enough people with the requisite skills.

              You assertion that investigation into systemic flaws in models isn't carried out bears no merit as this happens all the time on an ongoing basis. There are many papers discussing flaws in models and how to put them right. Furthermore scientists are not the people saying that we need to reduce CO2, they are saying: Here is the problem, now politicians and society have to sort it out.

    This is Good Science(tm). Examining preconceptions and adding nuance to earlier and simpler models. And you've reduced it to "lulz climate change int so bad rofl".

      This is Lewis Page. ALL his articles can be reduced to "lulz climate change int so bad rofl".

    Are they idiots?

    So we only have to be concerned about two weeks in late July and it's of little concern because if we're having a heat wave, it's expected to magically cool down during the (usually) hottest month of the year. With logic like that, I'm sure the rest of their findings are flawless too...

    Grass Growing

    This "climate change" is a total nonsense. On the (not that) rare occasions the grass in my garden goes yellow through a shortage of rain, 2 or 3 rainfalls later is is GROWING LIKE MAD and is as green as ever even in mid-summer.

    "Climate Change" is all about screwing gullible governments and the public for money to boost big business owners' bonuses.

      My statistical sample of one garden proves that climate change is wrong.

    Why are all the Reg env articles anti-AGW?

    Looking back at the list of "Related Stories" for this article and others I can't see one saying Global Warming is something we need to do something about. There are many saying "We don't need to worry because X". How did a team consisting of climate change deniers lock up climate reporting at the Reg?

      Perhaps they all read the harryreadme file of the CRU at East Anglia University and concluded that with such p**s poor documentation, change control and data management that it's impossible to conclude *anything* valid about the data.

      That's not a science view that's an IT view. It's a viable one given the highly secretive and at times down right obstructive way they have operated.

      Perhaps as a precursor question you might like to find the graph where CO2 rise *preceeds* rise in average global temperature.

      That would be quite a strong indicator that it was real.

      But what if it was the *other* way round?

        Re: Re: Why are all the Reg env articles anti-AGW?

        The CRU are a small part of the evidence collection on Global Warming, and I have read the readme file. It was hilarious but that's the way old school university departments used to write (and maintain) their software. I saw nothing more than some poor bunny being handed a huge software mess and having to sit down and sort out (partially by trial and error) how it all worked. The secretiveness is mostly a response to the concerted attacks on climate science being funded by those making a buck from CO2 pollution being free at this time.

        There is skepticism then there's stupidity. I'm not keen on sites that make me dummer.

          "The CRU are a small part of the evidence collection on Global Warming, and I have read the readme file. It was hilarious but that's the way old school university departments used to write (and maintain) their software."

          Except the CRU is *not* a university department which supervises a stream of MSc's & PhD's.

          It's a unit *specifically* set up to study climate change.

          The ability to *manage* the processing of *multiple* large data sets and *document* how those data sets were used to derive the conclusions that they have presented is *critical* to the credibility *of* those conclusions. It's a set of *baseline* skills.

          Especially given the *staggering* financial implications of those conclusions (which the UK is *legally* obligated to implement).

          The implication of the harryreadme file, especially *trying* to re-construct some of the data sets used is that documentation does not *exist*.

          If it *does* then people can discuss *how* those conclusions were reached and a *rational* discussion can be held as to how *reasonable* that is. It should be *widely* published.

          If I were asked to reproduce the evidence chain describing what *can* be called the *greatest* threat facing humankind and I said "I took a load of data and ran it through a bunch of software and this came out and it's conclusions are *really* serious," I would not trust my results.

          As always the evidence will end the argument. *Properly* conducted simulation experiments *should* have collected this as a matter of course. *Anything* else would be like cabalist studying the Bible or the Talmud for hidden patterns.

          That won't silence the critics but it will put the whole discussion on a more *rational* footing. Just because they are *numerical* experiments does not mean they should be conducted with any less rigor than physical ones.

      Strange how so many people STILL don't seem to understand what The Reg is about.

      It gives alternate news. The other side of the story. The stuff you don't get from mainstream news sources. Else you could just read CNN, or Sky, or BBC. What would be the point of El Reg? (you can even get all your IT articles from these sources nowdays)

      So if the mainstream is pushing "AGW"; then The Reg must give us the opposite or balancing view point. Hence the motto - "biting the hand that feeds IT". Of course, Reg is no longer only an IT news service, but a science / geek interest news service; but the philosophy remains - biting the hand, being the upstart. Reporting the alternative view.

      Which is perfect. Whether you agree or not, SOMEBODY has to give an opposing opinion. Especially in our current media climate (sic).

        Ummm. I think you might be confusing El Reg with Living Marxism/Sp!ked.

        El Reg's editorial policy on climate change is the standard reactionary stance taken by pretty much all the red top tabloids and a couple of the right wing broad sheets. There's nothing even slightly revolutionary or novel about it.

        Right, so where are the anti-vaccination articles? Those educating on homeopathy, astrology, creationism and scientology? Reg is a place people trained in logical thought come to catch up on relevant news. It devalues the whole place to see crappy cherrypicked misleading articles on climate change included with other useful content. 97% of climate scientists agree that AGW is a fact, The Reg does itself a disservice by promoting such incorrect and damaging anti-science propaganda.

    Consider a few things the article does *not* say.

    That the *same* 2 week period would be the one to avoid for long term effects of *other* plants.

    That the *same* 2 week period would be the one to avoid for long term effects in other parts of the world.

    It would also be an idea to study the detailed *biology* of these species to see IDK maybe this sensitivity correlates to some *critical* biological process in the grasses life cycle.

    Bottom line ecosystems *can* turn out to have *surprisingly* short vulnerability windows when climate effects can have serious effects on growth.

    Now in an *ideal* world I'd hope that might trigger a cascade of similar studies of other major habitats *globally* to see if *similar* results are found.

    Sadly I fear nothing quite that useful will happen.
