Plague upon Plague: Locust swarms, some 3 times the size of New York City, are eating their way across two continents

00 Locust Famines

As giant swarms of locusts spread across East Africa, the Arabian Peninsula and the Middle East, devouring crops that feed millions of people, some scientists say global warming is contributing to proliferation of the destructive insects. The largest locust swarms in more than 50 years have left subsistence farmers helpless to protect their fields and will spread misery throughout the region, said Robert Cheke, a biologist with the University of Greenwich Natural Resources Institute, who has helped lead international efforts to control insect pests in Africa. “I’m concerned about the scale of devastation and the effect on human livelihoods,” Cheke said, adding that he also worried about “the impending famines.”

“Despite the coronavirus pandemic, the region needs money and equipment to deploy insect control teams in the affected regions,” he said. New swarms are currently forming from Kenya to Iran, according to the United Nations locust watch website. Addressing the outbreak requires urgent, additional funding and technical help from developed countries, Cheke said, because the tiny size and budget of the United Nation’s Food and Agricultural Organization team responsible for locust monitoring and control is already overwhelmed. Changes in plant growth caused by higher carbon dioxide levels, as well as heat waves and tropical cyclones with intense rains, can lead to more prolific and unpredictable locust swarming, making it harder to prevent future outbreaks.

The desert locust (Schistocerca gregaria) needs moist soil to breed. When rains are especially heavy, populations of the usually solitary insects can explode. In Kenya, one of the biggest swarms detected last year was three times the size of New York City, according to a March 12 article in the journal Nature. Swarms a fraction of that size can hold between 4 billion and 8 billion locusts. At times, the locusts in East Africa have swarmed so thick that they have prevented planes from taking off and their dead bodies have piled up high enough to stop trains on their tracks.

The changing climate has spurred other insect invasions. Warmer winters, for example, are magnifying an ongoing bark beetle outbreak in western North America. Until the 1980s, periodic cold snaps kept the beetles in check. But since then, the tree-killing bugs have swarmed—not as fast as desert locusts, but just as destructively. Since 2000, they’ve killed trees across about 150,000 square miles in Canada and the western U.S., an area nearly the size of California. In recent years, historic bark beetle outbreaks have also devastated European forests. Other research shows that seasonal shifts caused by global warming are disrupting cycles of insect reproduction and plant pollination, including a recently documented decline of bumblebees, threatening food production in some areas. –Inside Climate News

    I believe looking at carbon in the atmosphere which is incredibly tiny as a reason for climate change is insane. The climate is in constant flux. I think one huge factor is the migration of the magnetic north pole. Since that is not man made people will not make money on it so the idea will be squelched for the most part.
    Of course even more important to remember is that all happening in this physical realm begin in the spiritual realm. That is something man CAN change by tuning in to the spiritual world and learning to act responsibly.

      Co2 is responsible for more robust growing cycles. Its a good thing! Blaming that for the locust issue is strange. More food growing is not responsible for the attack. Locusts will attack if there’s more food, or very little. Add the Covid19 thing, and we have a full blown Spiritual crisis that can only be, ultimately, a good thing. Cosmic flush cycle on steroids. People in seclusion will eventually confront their demons etc…or loose their minds in addiction to alcohol etc.

      Fear is the issue. Fear of “The End”, or “Death”. There’s no end to existence, or the life of what/who we truly are. Light.

    What a crock of shite! Where is all this ”global warming” you’re talking about? I’ve been to 3 continents in the last month and haven’t seen any warming in any of them. It’s colder and wetter than normal. Haven’t even spotted one locust. I think you’re trying to scaremonger and you should be ashamed of yourself!

    This is a decent breakdown of the locust problem,and where and how the swarms form. Don’t be too focused on “man-made climate change” as the cause, because . . . the sun. Which is at a period of minimum activity, and history reveals that, during other minimums, the “unprecedented” has happened before.

    And here’s the link for the video from the start, and it’s pretty much all about locusts.
