That's part of the equation for sure but extreme weather events have a massive impact where I live. Talking to producers, they are losing way more of their production way more frequently due to intense rain or dry events. As an exemple, someone who manages orchards was telling me that the norm now is to lose 1 year of harvest every 5 years when it was every 10 years 20 years ago. Talking with small scale organic veg growers who are less dependent on russian oil, managing weather events is the hardest part of their job. Currently, the soil is as dry as it usually is end of august where i am.

  > apocalyptic Bingo. Wars are already expanding, and the world is preparing for more. With food production suffering from climate change impacts, we are witnessing famine gaining ground in real time. The breed of politicians in power are doing their best to give pestilence a newfound hold on populace at large. And the fourth horseman is comfortably trotting in the wake of the other three.

    It's worth noting that while these dangers are real, they are largely economic, and so effectively a moral and political choice. Most production of most staple crops are higher than they have ever been, and still increasing most years. World bank data estimates for population growth is a 10% increase from 2020 to 2030, 26% from 2020 to 2050, and 42% between 2020 and 2100. OECD (FAO Agricultural Outlook 2021-2030) estimates agricultural production to increase by 1.4% per year for the decade, which translates to ~15%. So agricultural output is increasing faster than the population at this point despite the climate challenges. But this increase itself creates risks (e.g. soil degradation, pressure on water supply) that is compounded by climate risks and creates variability on a regional level that absolutely will be a massive problem even though it could be "easily" protected against. The famine risk largely comes down to pushing food out of economic reach of poor countries at points where local crops fail, and the very same economic conditions makes those countries less likely to be able to afford to maintain sufficient emergency stores. Of course, that there's food elsewhere that is just too expensive will be of no comfort to those who end up starving.

      Do you know if the agricultural production increase is driven by exploiting more land (e.g. taking over land from forest) or by increased productivity of the practice? Is it an increase in term of value or volume? Is it an increase of food production for human or raw agricultural output (which also include things like crops to produce ethanol, feed for cattle, etc...)?

        >Do you know if the agricultural production increase is driven by exploiting more land (e.g. taking over land from forest) or by increased productivity of the practice? That would depend on the country in question, and in some cases it can be both, with more land being used while production per hectare (or acre) increases too. From wht I know of most developed countries, it's a case of steadily less land used, but much more productively than ever. For example, the United States today produces more food in absolute terms than at any time in its history (an increase of nearly 200% in the last 70 years alone), while land used for agriculture has at pretty much the same time steadily been decreasing since the mid-20th century. Forests are even growing back as a result, with total forest cover having been very gently increasing since 1910 (links below) https://www.fs.usda.gov/sites/default/files/legacy_files/media/types/publication/field_pdf/forestfacts-2014aug-fs1035-508complete.pdf#:~:text=By%201910%2C%20the%20area%20of%20forest%20land,total%20land%20area%20of%20the%20United%20States. https://www.fs.usda.gov/sites/default/files/legacy_files/med... https://www.usda.gov/about-usda/news/blog/look-agricultural-productivity-growth-united-states-1948-2017#:~:text=From%201948%20to%202017%2C%20TFP,almost%20none%20of%20output%20growth. https://www.usda.gov/about-usda/news/blog/look-agricultural-...

        Sorry for pushing the logic but this doesn't account for the land, labour and resources required for the input which replaced former, less technical ways. How much is required to produce the seeds, seedlings, chemicals, energy and machines that weren't used before? In a really old approach farms tended to be fairly independant (e.g. producing their own fertilizers and using animal traction, animal who lived on the farm). This used land and labour which was accounted for but seems unaccounted for in more modern practice. In my opinion this underestimate the land and labour cost and creates a biased vision of the actual efficiency of modern agriculture.

    What a pile of nonsense you've just said. Our human society produces far more food than is even necessary to feed the entire human population. We produce so much that absolutely vast amounts are regularly discarded as refuse. Climate is not creating any real problems with food production that couldn't be remedied with a whole bunch of economic, logistical and practical solutions long before humanity ever reached genuine food shortages due to climate. Enough with this nearly religious forcing of a specific narrative. Also, famine isn't gaining ground in real time for the above reason, or at all for that matter. In absolute terms, more people today eat better than ever, and in nearly any case you care to look at of people starving, it's universally due to some regional political bullshittery instead of climate change. (case in point, children going hungry in Gaza right now) Temporary, shifting price rises on food are not the same thing as famine conditions by the way. Incredible how some people here just pull random claims out of their ass because they want them to be true as opposed to actually finding out if they have anything to do with reality.

I interpret this and GPs comment as the same: we have ways to solve these issues technically, but currently lack the other dimensions (trust, collaboration, incentives). As climate change adds risk, cost, and complexity, we are increasingly further from a solution, not closer. Your aggressive and dismissive rhetoric provides little in the way of substantive evidence or reasoning, either.

Where do you live? Rain and dry has not become more intense in most parts of the world, so local climate change of that sort isn't driven by CO2. For example, in the UK rainfall levels haven't changed since recordings began, there's no increase in outlier events either. A doubling of crop failure rates in just 20 years is definitely not something that should be immediately blamed on global climate change. It's possible there's some local climate change for non-CO2 reasons. In 20 years there's been just 0.2 degrees of average warming, which is barely detectable (CIs on weather stations are often much larger!)

    Britain has very stable weather compared to a lot of places. Not much difference in temps between summer and winter, no monsoon seasons, no hurricanes etc.
    - ndsipa_pomu 1y ago
      I would consider it "mild" weather rather than "stable". We don't tend to get extremes, but we do get fluctuations over the course of a day. I expect things will be different if the Gulf Stream shifts and plunges Britain into a mini ice age.

  Ah the propaganda troll... Talking about one thing and trying to deny it using another. That's lame. I'm talking about events not average. I'm also talking about facts. And if you really are in the uk you would know there has been lot of heatwave, intense rain and thunderstorm events in the uk the past few years. Just to push back on your bullshit, you can have the same rain yearly avearge as every other year and have no rain during the whole year but one. Your average would look good but your agriculture certainly not. Go bother someone else...
