The caps are melting and some people are all in on bringing back the woolly mammoth. How about the woolly rhino while we're at it? Maybe open a zoo in Death Va

The caps are melting and some people are all in on bringing back the woolly mammoth. How about the woolly rhino while we're at it? Maybe open a zoo in Death Valley to house 'em.

Gotta reproduce that mammoth jerky somehow.

  Yeah, it's not like it's gonna grow on trees... or maybe it will? https://www.bbc.com/news/av/technology-58709069 https://www.bbc.com/news/av/technology-58709069

    I'm not eating no tree jerky. Only from cloned mammoths like God intended.

Woolly mammoths were a geoengineer species that have no living proxy. Bringing them back is definitely a controversial project, but there's a case to be made that de-extincting the woolly mammoth could help prevent permafrost from melting.

  Of how many animals would we need genetic material from? are there enough dna available that it would be possible? if all animals will be clones, genetic diversity will be a problem. hopefully there is enough material available. seeing mammoths die out in real time would be more heartbreaking

Curiously, it turns out that elephants eating fauna actually promotes plant and tree growth. I remember reading something (ca 2007?) about the possibility that reintroducing elephants to the American Southwest could lead to reforestation of areas that are currently desert. Which, of course, doesn’t really provide good justification for de-extinctifying the mammoth (although as I say this, I wonder if they might acually play a role in preserving the permafrost, as per this recent Science Friday story: https://www.sciencefriday.com/segments/becoming-earth-how-life-transformed-the-planet/ https://www.sciencefriday.com/segments/becoming-earth-how-li... )

  In that case the humans started the global warming when made the mammoths extinct - how ironic, the industrial revolution is just the top of the cake

    Agriculture in general significantly reduced the amount of carbon trapped in vegetation. One of the causes of the Little Ice Age is often proposed to be the reduction of human population (and correspondingly, land area under cultivation) and reforestation after the Black Death, Mongol invasions, and the Columbian Exchange.

      The cooling associated with the Little Ice Age started in the 13th Century (per https://en.wikipedia.org/wiki/Little_Ice_Age#Dating https://en.wikipedia.org/wiki/Little_Ice_Age#Dating), though, while the Black Death was in the 14th.

  Pleistocene Park and albedo. I don't think you've got this exactly right, it's about grassland, not forest. Also forest is supposedly bad for permafrost, raising temperature slightly. > Pleistocene Park is a truly fascinating and daring experiment in the far Arctic, in Siberia, run by the Zimovs, Sergey and Nikita Zimov, a father and son scientific team, and their families. And they have this theory that large megafauna in the Pleistocene, things like mammoths and mastodons and bison, these large grazing animals, co-evolved with the grasslands that existed at the time. And so the grazers and the grasses maintained and sustained each other. > These large animals would trample the trees and shrubs that would otherwise compete with grass, and the grass would provide these grazers with this rapidly regenerating vegetation that they could continually graze on. But it went further than that in their estimation, because, together, the grasses and the grazers, according to their theory, were helping to keep the permafrost frozen. > So, for example, the grazers, just by being so large and by walking through these grasslands, were stripping away these insulating layers of snow, which allowed these frigid temperatures to penetrate deeper and keep that permafrost frozen. And grasses, just by virtue of being lighter, paler in color than trees, reflect more light and heat back to space. So they’re also keeping the land cooler. And so their idea is to bring back large grazing animals to Siberia, to recreate some version of these ancient Pleistocene grasslands, and thereby counteract the thawing of permafrost to some extent.

The correlation coefficient between # mammoths and ice cap extent is like, r=0.9 over the last 40,000 years. Obviously we need to bring the mammoths back, if we want to fix the global climate.

  Apparently, the presence of pirates is correlated with global cooling too: https://doctorspaghetti.org/pastafarians-pirates-and-climate-change/ https://doctorspaghetti.org/pastafarians-pirates-and-climate... Harrr!

Maybe this is what it'll take to seriously combat global warming. Filling zoos with wooly mammoths, and then extorting us into dropping global temperatures to keep them alive. Unless we're headed for a Day After Tomorrow situation. Then it might be the mammoths keeping us in zoos

Keeping open options is not madness,even in times of madness. Times change,but the capabilities persist.
