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.'"

Pine beetle

[blankinthefill]

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.

Re:Pine beetle

[blankinthefill]

That's why I said ONE of the reasons. The forestry techniques of the last century certainly increased the amount of deadwood and undergrowth. Anyone familiar with the forest situation in Colorado will tell you that the pine beetle is ALSO a huge contributor to the large increase of deadwood in mountainous forests there. The worrisome thing about the pine deadwood, though, is that it's very often standing deadwood, which, unlike living trees, torches easily along it's whole length. This can very easily carry a fire into the crowns of trees, killing them where they may have otherwise survived. No one is denying that what the article from a few days ago said is true. But the increase in deadwood because of the pine beetle hugely exacerbates that situation. With JUST the forestry techniques, or JUST the pine beetle, we would be seeing the increase in destructiveness that we saw 30 or 40 years ago. With both, we end up with the destructiveness we see today. (Note, YES, I know there are also other factors, such as overbuilding, poor building practices, and the proliferation of unintentional fire breaks. However, those are minor issues when you consider that, without the deadwood and undergrowth situation as it is today, those fires would likely not be the problem they are today.)

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.

It is an easy career change. You deal with bugs in both professions.

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.

I see it coming

Future news:

"The pest control industry is lobbying Congress for an increase in H1-Bs for pest control engineers. Stating ' there isn't enough qualified Americans coming out of school.'"

On Slashdot we'll see: ' I've been interviewing pest control engineers for years now, and I can tell yo that getting qualified people is really difficult. We get people with years of experience who can't describe how the poisons work on the pest nervous system and they can't even give a balanced equation on the compound's creation!"

"Same here! Why one guy couldn't use the sprayer properly."

And there will be ads for:
'Pest Control Engineer. MUST have 5 years of experience with the Pest Sprayer 2020 v 1.43.233, 5 years experience with the Pest sounder 3.42.11, 5 years of programming experience of the pest control API for Windows, BS/MSPE, Able to program the pest control Robot'

And there will be the "We are a Silicon Valley start-up with a new and ground breaking company that is a social media pest control company with iPad apps. There's a huge shortage of qualified people here in SF!" on Slashdot.

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.

Are you suggesting that the fossil fuel companies are headed by aliens? That would explain an awful lot . . .

Re:Pests

[lightknight]

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!

Re:Pests

[Genda]

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.
