Global Warming Spreading Pests Far and Wide According To Study
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.'"
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.

It's hard to see such people as myth when monster international corporations and uber-rich guys like the Koch Brothers are very much behind a massive campaign to discredit AGW researchers. I can't say whether they want the climate to continue to warm. They could be more mundanely evil in not giving a sweet fuck what happens 50 or 100 years from now, so long as their net worth continues up in the short and medium term.

I'm curious. Do you think the universe gives one sweet fuck about your political ideology. We can debate the scientific merits of these claims, but to attack them because they somehow collide with your political ideology is so fucking stupid I can only assume your either a moron or mentally ill.

Why, if you're investigating a scientific theory, would you both considering what Al Gore or the Koch Brothers had to say?
Because it's not about science for the denialists, it's about tribalism and primate dominance.

Dr Bebber said: "The most convincing hypothesis is that global warming has caused this shift."
*facepalms* Allow me to translate: "We really like the idea that global warming is responsible for this shift; bear in mind that this is a hypothesis, not a theory, so it has not been tested or validated in even a casual sense."
Show me group think!

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.
