The History of Climate Cycles (and the Woolly Rhino) Explained

    Check out Reactions’s Summer of Space video on the Northern Lights!

    Throughout the Pleistocene Epoch, the range of the woolly rhino grew and shrank in sync with global climate. So what caused the climate -- and the range of the woolly rhino -- to cycle back and forth between such extremes?

    Thanks to Julio Lacerda and Studio 252mya for the excellent Woolly Rhino illustration. You can find more of Julio's work here:

    Hi Eons viewers! As some of you have pointed out, I mistakenly cropped out Mars in the image we show when we mention that Milankovic was obsessed with ice ages on both Earth and Mars. Sorry to all of you (and the planet Mars) for the error! -Seth

    What?! Climate is driven by astronomical factors? But but but what about SUVs, plastic straws and aluminum cans?

    Always man caused global warming at the end of any story. It gets old and very predictable.

    We have all been 'educated' to know that animal farts caused the ice ages since none of them had volkswagons... Shame fresh water gulf stream changes dont get mentioned here...just a SMALL portion of the fart caused scenerio...And the Truth will set you free...and We all know that's NOT the desired outcome.

    , The buildup of carbon dioxide in the ocean liquid carbon dioxide was more than likely the cause of the Ice Age..! 1200 particles per million are recorded in the Ice Age only in geological time on earth mantle..!

    Climate science is crazy, fun, and complicated as all hell. Love it so much. There's just so much we don't know, and probably won't know until we observe it for ourselves thousands of years in the future. Let's just hope we don't collapse to the point of losing all our records!

    Theoretically. What would happen if we were to spread giant white sheets over some parts of earth to mimic ice ? as in reflect sun light in an attempt to cool down the climate.

    I love this show, but can we get a more monotone British person to explain stuff please? I’d watch way more and donate, and subscribe if you had a more Attenborough sounding voice. No offense to her but I go cross eyed and blank out even on my favorite subjects without the right voice.

    This is one of the most important videos on YouTube. Not only it helps us understand what we know about the climate cycles, it also shows without doubt that current global warming has nothing to do with natural cycles, but is 100% man-made.On the long term, learning how to manage CO2 and other greenhouse gasses will help us regulate the planet's climate, preventing it from overheating or overcooling.

    Funny that in this video they claim that a 6-7% change in the sun's output had little effect, but 6 weeks later they claim it's reduction was a significant contributing factor to the snowball Earth occurrences.... Be consistent.

    Its high time for us to take action for this global issue called climate change and not going back to history, the world knows global warming is a threat today.
