Marine Snow, which holds the Secret of the Ice Age Temperature

After dinosaurs became extinct due to environmental changes caused by meteorite impacts at the end of the Cretaceous Period of the Mesozoic Era, the climate eased into the Tertiary Period. However, from the late Miocene onwards, the temperature gradually decreased, and glaciers began to appear.
After the Pliocene, the temperature dropped even more as the Quaternary started to. As a result, Earth's glaciers have become more massive. These climate changes have had a significant impact on human evolution and development. But did scientists accurately measure the temperature up to several million years ago?

Ah yes The Crustaceous Period

[@mikenichols3849]

how can we be the only two who noticed the ficticious crustaceous period? time to unsubscribe.

[@pat8988]

Curiously, the subtitles have it spelled correctly.

[@mariannaweener]

Thanks for your incredible educational work! Vvvvery interesting and exciting!

[@DelusionalDoug]

Always wondered why there was no ice cap there. Thanks.

[@jasonborn867]

Solid research and excellent analyses, but all things equal I prefer your voice narration from prior videos. Superb work and look forward to your next production.

[@k1k2k3k4]

The content is superb, from the story line to the editing, it is great. The only reasons I can think of to why this has a few thousand views and not a few million are: 1. video is too quick and has too much content/second and 2. (mainly this and Im sorry to be frank) but the narration is appalling and ending every sentence with a hype is extremely ennerving. I think it is a deep misunderstanding. Maybe thats the usual narration for documentary channels in USA cable tv, but the people watching those channels (older, lower educstional attainment, passively consuming content) probably have nothing to do with the audience here (younger, actively seeking this content). As we are already interested in it, there is no need to try to make every-single-sentence as if you are narrating the last overtake in a F1 race. My advice is to watch Carl Sagan Cosmos series. See how he speaks. It is conpletely different, very relaxed and natural as you would speak to any friend while being accurate and cultivated. Honestly, you have tremebdous talent for this because the content is top 0.01%. You are at the gates of massive viewership. I hope the honest feedback helps. Worst case I volunteer to go to Dover and narrate it myself hahaha

[@timkbirchico8542]

the info in your vids is great. but hey bro, chill out on the voice thang. The info and research you put in is enough to get more views and more people educated. Thanks.

[@geonomad1]

Thank you.

you are titan!!!!!

[@concernednewfie]

Excellent video, but those loud sound effects sound like windows errors, for the first few I thought I miss typing or had a stuck key. It is possible that those sound effects are just too loud compared to the narration level. Like in action movies that drown out the voice via special effects.

[@andrewcrook2240]

Did it quit out 1/2 way thru?

[@geonomad1]

What do you mean?

[@LuciusQuinctiusCincinnatus111]

[@mikenichols3849]

there is NO such thing as the Crustaeous period...except maybe on another planet in a syfy film.

[@jamesdriscoll_tmp1515]

I dunno, the missus had some whoppers.

[@timkbirchico8542]

Russia fought against nazi germany in ww2 and were victorious. USA and UK came in later and mopped up the weak west of Europe. 20 million Russian military and civilians died. 5 million German troops died in Russia. USA lost about 450,000 troops in all in ww2. 0 civilians.

[@useodyseeorbitchute9450]

Well, if that panned out so poorly, then maybe the Soviet Union shouldn't have started this was as Nazi Germany ally in joint conquest of Eastern Europe?

Agw is fake

[@dadoVRC]

Nope. Probably your brain is.

[@timkbirchico8542]

dude, you are so wrong.

[@timkbirchico8542]

go read a good book.

[@brollyhessianovskov-ph1jc]

Have you looked into the other sides or just pretend to read a few lines of ar6 written by Grad students ?

[@timkbirchico8542]

@@brollyhessianovskov-ph1jc agw is clear and recognised as correct by all credible scientific research groups. go read scholarly articles on youtube. wake up or be a fool forever dude.
