I don't think it's worthwhile doing more than 1 post trying to convince people if or how much co2 can affect the earth climate, there's practically zero chance folks are going to change their mind on that stuff, but we can drill down into more simple hard facts and numbers on energy generation.
I have to say that first youtube is full of baloney, https://youtu.be/sZB1YtQtHjE?t=7m55s
Even at minute 7:55 he claims co2 causes the plant to require more water for the same plant growth, this goes against basic photosynthesis science.
This is basic photosynthesis science because we all should know that plants have to open up their pores on their leaves to absorb co2, but opening up their pores also means water loss if there are no co2 particles to absorb every second they are open, so more co2 means faster absorption of the co2 thus requiring less open pores that cause water loss in the process.
All up I think that guy rants on crap in that video that is just fundamentally wrong, I think hes just making up crap for more views.

more efficient at using carbon dioxide to thrive while requiring less water by tightening tiny pores called stomata that permit gas to enter without letting water out
BTW, I read fair amount of that book btw.
That's a great book that one, and I like how its been analyzed by a ton of scientists/engineers.
Even though I can use the most basic math to show how bad capacity factors are in wind/solar and use numbers from official government generation sources most pro-renewable folks just ignore it and tend to just spam 'CF facts' from garbage renewable-energy news sites.

One theory I have is that already
with the next Tesla roadster having a 200KWh battery and the Tesla truck rumored to have a multi-MWh battery I can't help but imagine that large cars will sit as high as 400KWh, like the American King Cab family vehicle or cars of that nature.
And if they have two of those large EVs in a family and do a lot of driving then its 800KWh that could be consumed in a day in an extreme event like using both cars and driving home from a road-trip holiday or any long-distance travel.
Then the oldest kid is growing up in the family and he gets his first car at 200KWh car as well. Plenty of families do have 3 cars these days in the latter years of the family when the kids have grown up.
Being the future everything will be low carbon electric based so no gas oven to cook with.. There are lots of double compartment electric ovens now at the 10KW mark, so if its a large family and they cook for 2 hours thats 20KWh gone, the electrically heated house and pool etc. A solar roof + power-wall will only be good at running the home appliances and not vehicles etc. Can a home solar roof pull in 30KWh every day of the year?
All up it won't surprise me that in more situations we could have the 1MWh house-hold per day for our happy low carbon future the way these EVs etc are going.
I liked this bit out of the book because this is what I been imaging too, the true overhead of it having a pure all renewable USA means constant replacing of renewable generation equipment on a scale that is hard to imagine.
It also means that 5 years after completion, we'll have to start recycling and replacing the solar panels – all 18 billion square meters' worth.
That's billion with a B.
A 40-year solar refurbishment schedule would mean the recycling and replacement of 1.23 million square meters of worn-out panels, every single day, rain or shine – forever
Then I think in about 25 years time we will have a fair amount of electric flying cars. https://www.youtube.com/watch?v=ohig71bwRUE
