  1. Good explanation. However, in his most recent video, he says “the reason we’re not in an ice age now is because of CO2”.

    Not th ed sun.

  2. The problem is that the Little Ice Age (LIA) do not sit well with Milankovitch Cycles. However there is quite a a lot of correlation with volcanic activity at solar minimums.

    What I find fascinating is the coincidence/coordination of Icelandic volcanic eruption and their propensity to drastically affect the Northern Hemisphere’s weather/climate patterns and trends. Iceland is one of the most volcanic places on the planet with over 160 volcanoes and experiences a major volcanic eruption almost every decade. The close proximity to Europe and the prevailing western winds makes it possible for volcanic ash and gasses to reach the continent.

    Far Reach of the Tenth Century Eldgjá Eruption, Iceland
    Abstract

    At the end of Iceland’s settlement period in the 10th century, a great basalt fissure eruption known as Eldgjá (Fire Chasm) occurred near the southern settlements and destroyed a portion of them. This lava outpouring was one of the two largest terrestrial fissure eruptions of the last 11 centuries. Historical documents from Iceland, western Europe, and the Middle East are used to trace the eruption’s possible climatic and demographic consequences. The cloud of aerosols from the eruption, traversing northern Europe, dimmed and reddened the Sun. There followed a very cold winter, famine, and a widespread disease epidemic during the next year and, again, 5 to 7 years after the eruption, probably as a result of the long-lived stratospheric aerosol veil.

    The 1783-84 event.

    Massive Laki volcano eruption led to unusually cold winter in Europe, Rutgers-led study says …

    An enormous volcanic eruption on Iceland in 1783-84 did not cause an extreme summer heat wave in Europe. But, as Benjamin Franklin speculated, the eruption triggered an unusually cold winter, according to a Rutgers-led study.

  3. Rolf Witzsche also shares some data showing a correlation between 10Be and ice age. The solar radiation is not enough.

  4. Understanding the M.Cycle is very important. However, there is more to this current ice age cycle than that. The other thing is answered by “Plate Tectonics”, and how it influences the Atlantic Conveyor. Currently, warmer Pacific waters must go around the horn of Africa and north toward Greenland. But until 2.6 million years ago, a good part of those warm currents entered the N.Atlantic directly through the Isthmus of Panama, delivering warmer temperatures more efficiently.

    When the Isthmus formed, and shut off the warm Pacific currents, the ocean temperature did not get warm enough to melt the northern ice sheets, as before. This is why the Pleistocene Period is such a long glaciation phase. Open the Panama isthmus, and the permanent ice sheets will disappear.

  5. Of course, this was all taught in Climatology 101 years ago as part of the curriculum for Meteorology majors when I was a freshman in college (1971); doubtful this is still being taught, as science – in general – has been hijacked by the left for nothing but power and political gain, and every thinking person with half a brain knows this to be so. But the point I want to make is that this short video is EXCELLENT and should be viewed by all climate “agnostics,” as it lays things out in a very understandable way, even to the layperson. Kudos to the makers of this video!

    • Hi, I’m the guy that made the video. I’m not an alarmist. In fact, the first video says nothing about CO2 or climate change beyond the Milankovitch cycle. I didn’t want to talk about it. It was only after so many people misinterpreted my video as an attack on climate change that I made a follow up video explaining that it does not. Nowhere in any of my videos do I even talk about whether or not we should be alarmed by this. Just because someone disagrees with you doesn’t make them a rabid alarmist.
