About: Why almost all coal was made at the same time


CORRECTIONS


So this video was quite rushed because I wanted to get it out in time for the #teamtrees launch. Here are a couple of things I got wrong:


Not ALL coal was made during the carboniferous period. There exists some younger coal here and there that formed under rare conditions that enabled it in spite of the presence of capable fungi. I did film myself saying that but it was lost it my rushed edit.


Photosynthesis is more complicated than I described. It involves water for a start. And it seems that the oxygen released during photosynthesis comes from the H₂O not the CO₂. Though I haven't be able to verify that.


And here's a non-correction! The thing I was holding up at the start was not charcoal. It was a coal dust briquette. You could argue that the briquette was made recently but the coal it's made of is old!


So yeah, the thrust of the video still stands but it's been a learning opportunity for me!


A final thought on planting trees for carbon capture. A lot of comments saying "what's the point? When the trees die the decomposers will release the CO₂ back into the atmosphere. But really this is more about planting *forests*. In a forest, when a tree dies, another tree grows in its place recapturing the carbon. But also, it's my understanding that it takes a very long time to release the CO₂. Like hundreds of years. So in terms of tackling climate change which is a problem of human time scales, it's a useful endeavour.
Charcoal is not coal. Fyi
So there was a period of time everywhere on earth where there were trees that the floor was just hardwood flooring?
I'm sorry but this team trees thing just isn't worth it, I see shit all the time that tells me what I did planted a tree and often without paying.
wow, charcoal briquettes are millions of years old.
At 0:05 -that looks remarkably like a charcoal briquette. No coal seam nearby?
We think we know all about time, yet haven't grappled with the speed of light slowing down.
Sixty million years of perpetual growth and no decomposition. Sounds like a Fed economist.
It is funny how he is holding a Charcoal Briquette and calling it coal and I am sposed to think he knows what he is talking about?
since when do we measure time in m (meters)??
how do you date coal? C-14 dating can only be done on materials no older as 60.000 years......
The oxygen that is released by plants is from water. Not from carbon dioxide. The oxygen bound to carbon dioxide is tightly bound.
Noah's flood, that's why?
I guess Noah's Flood😑 saves you a lot of time thinking
It all happens at the same time... nothing more than like 60 million years
There is a mini mistake when you say O2 comes from the breaking of O-C-O; CO2 is chemically "stacked" into glucose (fructose, cellulose, lignine...), whereas the O atoms from O2 come from water molecules ;)
Trees don't cost a dollar what a rip off (they grow from seeds). Also we need carbon in the atmosphere to stop us freezing.
im fucking sick of hearing about team trees
Nobody got mad at those trees for changing the climate way back in the day
Responsible for coal is first of all the flood. I thought it should be a one time event 😃? !


Coal stock


Coal is extracted from the ground by coal mining, either underground by shaft mining, or at ground level by open pit mining extraction.

Languages:

Coal is primarily used as a solid fuel to produce electricity and heat through combustion. World coal consumption was about 7.25 billion tonnes in 2010 The price of coal increased from around $30.00 per short ton in 2000 to around $150.00 per short ton as of September 2008. In early 2015, it was trading near $56/ton.
