  • Sure climate change is bad but at least it's not causing more cases of flesh eating bacteria

  • or somethingno you're kidding, seriously?

  • Hey global citizens, Julian here for DNews.

  • We talk about climate change a lot here, probably because it's a massive looming problem that

  • will affect the globe in profound ways.

  • You already know most of them by heart I'm sure: melting ice caps, rising sea levels,

  • changing rainfall patterns that lead to droughts and food shortages.

  • All bad stuff that's in the not too distant future.

  • But what if I told you that climate change is causing problems already, and some of them

  • are truly unexpected?

  • Take for example a recent anthrax outbreak in Siberia.

  • If you're like me, you only know anthrax as this white powder that gets mailed to someone

  • and then everyone freaks out because it could kill you.

  • So you may be wondering what madman is mailing a bioweapon to people in one of the most remote

  • places in the world.

  • But in reality, the bacterium that causes anthrax infections, Bacillus anthracis, occurs

  • naturally and infects an estimated 2,000 people each year.

  • Back in the early 20th century, anthrax outbreaks were common in Siberia.

  • Anthrax infections killed over a million reindeer, and they were buried in about 7000 burial

  • grounds by the indigenous Nenets.

  • But since then it's been quiet, with the last outbreak in Siberia happening in 1941.

  • Now the same bacteria that caused those outbreaks could be responsible for the 20 Siberians

  • who contracted anthrax in August of 2016, and I do mean the exact same bacteria.

  • The current hypothesis is after the infected reindeer were buried, the bacteria were essentially

  • refrigerated by the permafrost heaped on top of them.

  • Now that temperatures are climbing upward, that frozen soil is starting to thaw, unleashing

  • spores across the tundra and infecting reindeer and people anew.

  • If rising temperatures are the culprit, then the Nenets can expect anthrax outbreaks every

  • summer.

  • There could be other dormant bacteria up there waiting to be reawakened too, like bubonic

  • plague, or a disease that hasn't occurred naturally since 1977, smallpox.

  • Climate change might be doing more than revive frozen microbes north of the Arctic circle;

  • it could be helping microbes closer to the equator too, like Vibrio vulnificus.

  • That little guy is also known as a flesh-eating bacteria, and it does well in warm and brackish

  • waters.

  • Guess what climate change causes more of?

  • Warm and brackish waters.

  • Global incidents of V. vulnificus have been steadily rising for the last 4 decades.

  • Now there are about 80,000 cases in the US each year.

  • Before you shout that correlation does not necessarily equal causation and bring a tear

  • of joy to my eye like a proud parent, a study in June published in the Proceedings of the

  • National Academy of Sciences found that warmer surface ocean temperatures are causing blooms

  • of the bacteria and are associated with the increased incidence of infection in Northern

  • Europe and the US Atlantic coast.

  • Most of the infections come from eating contaminated seafood raw and in those cases the cholera-like

  • symptoms like diarrhea, cramping, and fever usually pass after 3 days.

  • But Vibrio can also find it's way into open cuts, causing lesions that grow rapidly.

  • 20% of the time these infections are fatal.

  • Climate change isn't some far-off problem with hypothetical impacts that will be felt

  • 50 years from now.

  • It's creating problems already, and some of these problems come out of left field,

  • like these revived and revitalized bacteria.

  • Don't worry though, because the hotter temperatures can kill bacteria too!

  • Except that's happening in deserts, where the bacteria helps keep the soil from eroding.

  • Seriously climate change, can you just chill out?

  • Another unexpected side effect of climate change?

  • A refugee crisis.

  • Seeker Stories has more info on that here.

  • And climate change might be happening faster than we expected.

  • Trace has more info on that, here.

  • Now have you noticed the changing temperatures affecting your life in ways you didn't expect?

  • Like I for one basically can't play PC games anymore without my room turning into a sauna.

  • Let us know in the comments, subscribe for more and I will see you next time on DNews.
