An anonymous reader writes "New research has concluded that global warming is helping pests and diseases that attack crops to spread around the world. 'Researchers from the universities of Exeter and Oxford have found crop pests are moving at an average of two miles (3km) a year. The team said they were heading towards the north and south poles, and were establishing in areas that were once too cold for them to live in. The research is published in the journal Nature Climate Change.'"

        That's not exactly correct, but it's really poor science to talk about an entire body of work involving thousands of separate research projects and researchers, in overly broad and general ways. Some work certainly has more rigor (and is therefore more authoritative) than others, and this news blurb talks about such a diverse population of pests (virii, viroids, bacteria, fungi, insects, nematodes... ad-infinitum) impacting everything from forest health to the growing occurrence of tropical fungal disease in humans occurring in temperate regions, that the trends spoken of here are a powerful indictment on issues of global climate change.. the average movement for pests (most thrive in warm climates) is about 3 km per years north and south (migration towards the poles.)

        So at one level you're right, this could be gremlins herding trillion of lifeforms from dozens of different classes away from the equator, however watching these creatures move in lockstep with local changes in climate (and even micro climate), and watching what amounts to tropical conditions carry these lifeforms to places they've never been before, suggests that your observation, while humorous lacks a certain intellectual vision.

    I wonder if the selfish and short-sighted people who want global warming to continue because they live in areas that would benefit are still so enthusiastic...but I guess pests are as at least as easy to ignore as wars, refugees and food shortages.

    • This theory (that pests are moving farther north because it's no longer as cold) ALSO supports the idea that other things, like plants and animals can also be raised farther north because it is warmer.

      If you think that's offset by some parts becoming too warm to support some crops and animals, then you must ALSO weigh that with the aspect that some pests will find it too warm and so there is some benefit. But since jungles grow everything in abundance it's pretty hard to argue that warming is not a net gai

        The problem here is that it seems rather likely that the habitable zones won't grow in size. Rather they will shift in latitude. There will be very real geopolitical ramifications to the North American and Eurasian growth zones jumping northward. Imagine the North American Grain Belt heading a few degrees north. All of a sudden, large areas currently under cultivation in the United States cease to arable, or at least cheaply arable. At the same time, Canada gains large amounts of arable land much farther north. In a few generations, you could see US food security compromised, with large amounts of the grain it needs suddenly in another sovereign country. The US will almost certainly be able to come to some accord with Canada, but other parts of the world may not be so lucky. A brief survey of historic and prehistoric migrations heavily suggests that people don't just sit on their asses and quietly die out when they can no longer get enough food and water.

        • large areas currently under cultivation in the United States cease to arable, or at least cheaply arable. At the same time, Canada gains large amounts of arable land much farther north.

          There are factors other than mere temperature that go into whether land can be used for growing crops. Much of the soil north of where Canadian farmers currently grow their crops is either very poor or next-to-nonexistent. The Canadian Shield consists largely of volcanic rock. You can't grow a crop in that even if

          • The Canadian Shield is an extension of the Appalachians. The region I'm talking about is the north of the prairie provinces and the Northwest Territories, which are an extension of the Great Plains. There's a helluva lot of territory between the Rockies and the Canadian shield.

            • by riverat1 (1048260)

              That's true but the soil in the Canadian prairie provinces still usually isn't as good as that found in the US Midwest. It was scraped pretty thin during the last glaciation while the Midwest continued to build up soil since it wasn't covered by ice all that time.

        • by Burz (138833)

          Its a worse problem than that. The soil in poleward locations may not be suitable, tending to turn into desert instead (at least in the geologic near term). Land area is also less abundant near the poles, especially when you consider that Antarctica will remain ice-covered deep into the arable land crisis. Most plants and animals that help keep a temperate zone healthy probably won't be able to migrate quickly enough to the unprecedented rate of warming we have unleashead.

        Corollary: deserts grow nothing in abundance.

        Actually your statement is quite incorrect anyway. Of all the major food sources used by humans only yucca/cassava grows well under jungle-type conditions, and to a lesser extent rice. Corn, wheat, rye, barley, potatoes, and sweet potatoes all do very poorly if they grow at all, and only a few varieties of yams do well.

      http://en.wikipedia.org/wiki/Colorado_potato_beetle

      "The beetle was discovered in 1824 by Thomas Say from specimens collected in the Rocky Mountains on buffalo-bur, Solanum rostratum. The origin of the beetle is somewhat unclear, but it seems that Colorado and Mexico are a part of its native distribution in southwestern North America.[2] In about 1840, the species adopted the cultivated potato into its host range and it rapidly became a most destructive pest of potato crops. The large scale use of insecticides in agricultural crops effectively controlled the pest until it became resistant to DDT in the 1950s. Other pesticides have since been used but the insect has, over time, developed resistance to them all.[3]"

      So, when you stop patting yourself on the back for confirming your bias, you can spare a moment, and read up on one of the pests mentioned in that article. The Colorado Potato Beetle is immune to DDT (an achievement in of itself), as well as a number of other pesticides, which were holding it at bay. In other words, this thing used to destroy potato crops, and only by blanketing crops with pesticides did we slow it down some. It evolved...our pesticides have not; what more, I imagine many of the farmers in the affected areas have decided to ride the 'organic' cash cow, and not use any pesticide on their crops...thus ensuring that this pest won't even be slightly dinged by whatever extra proteins it has to manufacture to get around the poisons we normally spread on those crops; instead, it will grow fast...much faster.

      Global Warming had jack shit to do with this pest's rise...only the laziness of mankind let it reclaim ground. And I imagine that the other pests are, perhaps, due to similar, or other, explainable reasons. But I guess a little fact checking takes too much time these days...

        • You seem to have missed entirely what was written about this beetle: it's essentially a locust. Before DDT, also known as the nuclear weaponry mankind used to tell certain orders of the insect civilizations to stop being dicks, these little pests destroyed, like locusts, potato crops. These pests (notice that they are called the Colorado potato beetle...not the Irish potato beetle) are indigenous lifeforms, that eat the wild *organic* stuff as well as the mono-culture stuff (they didn't eat the mono-culture

            All I know about the Colorado Potato Beetle I got from the wiki link that you posted. I have been certified for pesticide application though in forestry, not farming and have applied quite a few pesticides, mostly herbicides but occasionally insecticides and fungicides so I do know something about pesticides which seems to be more then you do. The wiki article itself says,

            High fecundity usually allows Colorado potato beetle populations to withstand natural enemy pressure. Still, in the absence of insecticides natural enemies can sometimes reach densities capable of reducing Colorado potato beetle numbers below economically damaging levels. A ground beetle, Lebia grandis is a predator of the eggs and larvae and its larvae are parasitoids of the Colorado beetle's pupae. Beauveria bassiana (Hyphomycetes) is a pathogenic fungus that infects a wide range of insect species, including the Colorado potato beetle. It is probably the most widely used natural enemy of the Colorado potato beetle, with readily available commercial formulations that can be applied using a regular pesticide sprayer.

            Which sounds like they are controllable through spraying fungus on them as well as encouraging their natural predators to flourish. As y

    This is actually believed to be one of the main culprits of the explosion of pine beetle infestations in Colorado, as the beetle is now able to survive at higher altitudes than it was previously able to due to increased warming, which has allowed it to infest species of trees which have no natural defense against the pine beetle. This in turn has driven a huge increase in the amount of standing and fallen deadwood in mountainous forests, and is believed to be one of the reasons behind the dramatic increase in the severity of wildfires in those areas.

      One thing that has exacerbated that is the length of the warm season has grown enough in some places that the pine beetles are now able to have two generations in a year which has the effect of increasing their numbers far beyond what was seen in the past.

    This shift in where water goes will also make a shift in where and how well plants grow. Some plants will die while others will begin to thrive and flourish. The animal life which depend on the water and the plant life will also shift, di

      Sure - if you don't want to think about it. Or, maybe, the climate change is affecting different species differently. Polar bears are losing their hunting ground due to warmer seas, and corals are dying because of the ocean acidification, just as pests in temperate climates are spreading with their spreading temperate areas. No need for God or assuming climate change doesn't exist - just basic reading comprehension and a willingness to learn.
