For example, your video you claim 'Every ice age the planet has had is due to volcanoes' etc. Evidence? Where's your own research on that? Research is not simply googling or browsing a website that fits your biases. Research is the actual scientific method to discover answers for yourself. In this case, you would need to go and look into the ice cores stored in the arctic and take samples on a molecular level, analysing the geological history of the earth. You'd have to go up a volcano and dig into the rock surface and extrapolate the data of eruptions vs ice ages, find a global correlation across the board that is then checked, double-checked and triple checked by other professionals to be sure you're not messing up your results.

Sure, you CAN do this, it's all possible to do by yourself, for free - the internet can teach you the how. But you won't. You will just browse the internet, right?

Even then, a quick google shows me this statement is false. I found that it says volcanoes can and may have potentially started a little ice age, but:

The onset of an ice age is related to the Milankovitch cycles - where regular changes in the Earth's tilt and orbit combine to affect which areas on Earth get more or less solar radiation. When all these factors align so the northern hemisphere gets less solar radiation in summer, an ice age can be started.

So right off the bat, this video appears to be false by doing my own research, in the style that you presumably suggest me to do. Now what?
