We have been told for years that malaria will spread because of global warming.

Unfortunately for the alarmists, but fortunately for the rest of us, the reverse is the case.

The Our World in Data recently updated a report, originally published in 2015. According to it, WHO data showed deaths from malaria have fallen by 48% since 2000:

https://ourworldindata.org/malaria

 

 

The incidence of malaria has also fallen markedly in most of the countries affected in 2000:

 

incidence-of-malaria

incidence-of-malaria-1

 

For instance, in Kenya incidence has dropped from 273 to 166 cases per 1000 of population.

You should also note how malaria seems to have been almost totally eradicated in places like Turkey, and much reduced throughout Asia.

They also include this very telling map. Note the green regions, labelled “formerly malarious”:

This does not suggest to me that malaria is spreading because of a slightly warmer climate.

 

Finally, take a look at this old map from the US Census in 1870:

The below map shows the distribution of malaria deaths within the United States in 1870. Malaria was prevalent in most parts of the US, but especially so in pockets along the coasts.

    Global warming and malaria: knowing the horse before hitching the cart…

    Paul,

    that’s incredibly valuable information.

    Only one question. The areas showing “No data”. Is that because there are no recorded incidents of malaria or that they are not researched.

    I suspect it’s the former as Australia’s Northern Territory was recorded as a malaria area on the map of “former malarial” but in both the 2000 and 2015 maps, there is no data.

    Cheers.

      Sorry to all if it’s a stupid question.

        Malaria was endemic in the north but was declared eradicated from Australia in 1981.

        There are still 700-800 cases per year but they are almost exclusively in travellers who caught the disease while overseas.

        There are however very rare local cases particularly in the islands of the extreme north close to New Guinea. There is still some native canoe trade between PNG and the Torres Strait Islands where Papuans sail over to Oz territory and bring infections with them. The extreme concern there is not malaria being vectored in but rather multi-resistant strains of TB which are also rampant in PNG.

        I would suggest the grey areas are there because there is no malaria there.

    One more to add to what others have or will post on malaria not being just a “tropical disease.”

      Thank-you yonason for making me aware of a reasoned online debate about “Professor Reiter on malaria in the “Little Ice Age” “.
      The big problem I see with the many arguments about the LIA is people assuming that during this period the weather was always cooler than today. This is a bad error, for although overall the LIA was on average colder than now, it still had some very hot periods, and probably much more extremes of natural variability than now.
      Look for instance the records at the British (and some European) weather records from this site — https://www.booty.org.uk/booty.weather/climate/1650_1699.htm
      Note that there are periods of extreme cold, there are droughts and deluges, and there are some warm periods. E.g. 1651-1654 was a very warm droughty period, as was 1666, however between these two dates were periods of normal seasonality, mixed with widespread floods, and extreme cold. What is very evident is the weather variability, and the difficulty in reliably producing food this causes.
      During the LIA malaria was generally endemic in most of Europe, as has been noted by epidemiologists. In fact researchers find it (or writing about the symptoms) were in Europe in many historical writing going back to Roman times and before.

    The mosquito would probably be close to eradication ….. at least in populated areas …. if the most effective and affordable deterrent, DDT, wasn’t erroneously banned. Sort of like what they want to do with fossil fuels. Even the WHO admits DDT is safe if used properly and they recently suggested its’ reintroduction.

      The “vectorial potential” of mosquitos in many former infection hot-spots is already fully re-established*. Climate change is therefore completely irrelevant.

      If malaria should come back, somewhere, the answer will be to issue mosquito-nets with insecticide on them – which will snuff out the mosquito populations and the parasites they carry.

      We had a discussion here about this subject a few months ago. Of course, such a juicy alarmists’ lie will be repeated every few months. A CAGW myth differs from an epidemic disease in so much as – there is no cure.

    and now tiger mosquitos are spreading through France, no doubt the fools will claim global warming or somesuch, I’d suggest increased global trade and travel.

    Paul

    My only slight caveat is here: “This does not suggest to me that malaria is spreading because of a slightly warmer climate.”

    What ‘slightly warmer climate’ and warmer than what? Moreover, as to the substance of the claim, such as it is, Reiter has already made clear that some of the greatest epidemics of malaria have occured in savagely cold regions, eg Archangel.

    The problem with these apparent concessions to catastrophists is that they are wholly unscrupulous, and will use them however inappropriately.

      “…concessions…”

      Field Marshal Alanbrooke, a blunt Northern Irishman, when presented with a fantastic, wheedling, argument from Churchill during WW2 would reply:

      “I flatly disagree!”

      He despaired of people like Churchill when they got “a bee in the bonnet.” His diary wearily relates ‘Winston has been totally fixated for the last week on his idea of all our strategic reserves descending “on the tip of Sumatra!!!” ‘

      After all, the beeb are enthusiasticly bonkersd and beyond all reason about the greeD agenda and the ruinable industry where, the blades and tips of birmincers kill far more bats than rather inclement weather – by a factor of 10⁴: 1 – probably.

        In the last fifty years there have been about 50,000 cases of malaria in this country, brought in by immigrants and travellers. The number of secondary cases caused by local transmission has been – zero. Which shows that England is an unfavourable country, for the parasite to re-establish itself.

        For one thing, there is only JUST enough rain in the summer months to breed sufficient mosquitos (despite that infuriating whine in the middle of most nights!). A minimum of 80mm in August would be needed but there is rarely this much in the South.

    What surprised me was the statement that the Netherlands had only been declared malaria free in the early 70s. Most of us would hardly have thought of it as a malaria country.

      “…a malaria country…”

      It has always been marshy. That makes it natural malarial territory.

      http://www.pnas.org/content/100/17/9997

      This survey of malaria around the North Sea basin makes it clear that the high point of malaria was during the Little Ice Age [sic].

      One will frequently read “malaria is a temperature-dependent illness.” Yes, but this means a summer illness (when the insects multiply) not an illness of tropical regions. Northern Canada is hot and plagued by insects in the summer!

    A few malaria facts: No infected humans = no infected mosquitos. Mosquitos are “born” clean and must bite an infected human to acquire the plasmodium, and then it takes several days before the parasite transforms into a transmissible form. Malaria occurred all over the world, including North America and Europe as far north as Siberia! Climate did not kill it out. DDT did. Spraying was continued long enough to eliminate all human carriers. The mosquitos are still here, but the human vectors have either died or were cured. In the chart “Global Malaria Deaths by World Region,” it is evident that Africa needs DDT. India has continued DDT after the ban and to this day. They still have malaria, but it is greatly reduced. If African nations started an aggressive DDT application program on interior wall like India does, they too could reduce malaria to a manageable level.

      “…needs DDT…”

      Or just long-lasting insecticide-treated nets at £2 a net. Keeps out other nasty insects and what they carry, as well

    We received a good deal of training on diagnosing and treating Malaria as SF medics. One factoid I found interesting is that it is believed that Sickle Cell disease is the result of an adaptation in people that live or lived in places where the particular variety of Malaria (Usually Plasmodium Falciparum) is/was particularly deadly. The sickle shape of the Red blood cells makes it difficult if not impossible for malaria gametocytes to invade the cells and reproduce.
