A Shift in the Earth's Cycles Is Coming - How Will It Affect You?

My favorite way to go to sleep, gently lullabied by his lilting voice telling us of our future horrors. Yet it’s not nightmare fuel. That’s talent. He’s like the Bob Ross of science.

Are you serious? I was just browsing for a video to watch along my meal, refresh and what do I see? An almost 2 hour Astrum video posted a minute ago. Thanks man! Edit: What exactly in my comment makes disappointingly many people assume that I eat for 2 hours straight? You people do comprehend, that a video can be continued being watched after one has finished eating, no?

I don't think I've ever learned more about weather in 2 hrs. If not for the all mighty astrum I'd have zoned out. Truly fascinating

This is the best summarization of the climate I've seen. It's rare I see the solar cycle discussed to the point of nucleation sites. I wish you had discussed the long-term brightening of our sun (models vary, but scientists estimate the sun was 30% dimmer during the time of the dinosaurs than today), as well as vulcanism. Regardless, this is the most comprehensive video I've seen and I wish more people would see it. I know I'll be sharing it with people.

1816 The global "Year without summer (big freeze)" 3°C temperature drop and crop failures. April 1815, volcano Mount Tambora began to violently erupt. Millions of tons of ash, dust, and sulfur dioxide were released into the atmosphere, casting a temporary chill across the planet as it Blocked out the Sunlight for months on end. Documented around the world in literature.

This narrator is so good at speach and oration, "I" actually look forward to learning.

Dear Astrum team I want to congratulate you on this beautiful production of almost two hours on the discussion of global warming. The extensive scientific research that you addressed and delved into is simply brilliant. Bravo !!! I am a Geologist and yes, climate change is scary, but through this documentary, you manage to bring the true and essential substrate necessary for us to understand the relevance and responsibility of our role as human beings within this complex cycle that has governed our planet for more than 4 billion years. Continue to improve knowledge of astronomy and science in general with your videos. Once again, congratulations to everyone on the team and especially to you, Alex McColgan, for the wonderful work leading your Astrum.

Watching from Rajasthan Todays Temperature was 47.8 ‘Celsius

Solar cycles also affect the polar vortex. Solar maximums put more energy into the atmosphere causing increases in the variability of the polar vortexes. At solar minimums the polar vortexes are basically circular. Solar cycles have also been linked to the magnetic connections between the earth and saturn. Magnetic connections between the sun and planets is at least as important as the gravitaional connections. Also affecting the heliosphere is the cyclical connections with galactic influences. Good job. Well put together discusion.

Amazing video! Had to watch it in parts because it is so long, but did'nt want to miss anything. Thank you for researching all the facts for us and let us know cleary what is assumption and opinion, and what is not. Favorite part was 'Context is important'!

“It won’t likely be something that ends human civilization all together” those odds don’t give me much comfort 😅

So in 10 or so years a spring tide with an onshore storm surge will deffo break records in loads of places .

Thank you once again, Alex. Your documentaries are excellent and so instructive. They always bring us good information.

The is figging excellent. Thank you Alex. I have learned so much about each of these cycles and how they interplay. Some stuff I knew, some I thought I knew. But this has been truly educational.

Amazing job! One of your best videos yet!!! Thank you!!!

Great video, thank you! I knew about the existence of many of these cycles, but it is nice to see them all compiled in one work and also described in such depth.

I just love how Astrum pronounces ”earth”. It’s like ”örth”, the sound that the Swedish letter ö makes, if a bit more nasal.

Love the vid! These long ones really get me chilled out. I wondered if you'd do a video about the giant solar flairs we've recently had, showing the arura. Seeing one from the UK was pretty amazing. I would love to understand what the solar flairs are, what they mean and the effects they have on us and space around us.

Really nicely done!
