If we are talking about oxygen, we have to talk about a phenomenon, that can be called „absolution“. Certain resources, if being abundant, are enabling life and even technology to go forward onto a higher level. Light for instance enables animals to develop an absolute sense, the optical sense, which isn‘t depending on certain events, but produces an infinite stream of information. Therefore the former limits of relatively rare events, don‘t exist anymore. So radiation sets in. Same thing about electricity, an absolute kind of energy, which can be used for a nearly infinite number of purposes, as long as it is always available. All systems using these absoluta become transparent in regard to these certain resources, gaining new degrees of freedom, that didn‘t exist before.

The most significant fact about all this is that I'm watching this video. Just a few years ago I read a book on oxygen and the dinosaurs. But today I'm not reading a book. I'm watching a You tube video. That's new. That's important. Yesterday I watched a couple videos on dinosaur feathers. The last revolution in dinosaur was probably the 'hot blooded dinosaur' revolution. I like millions of others read Bakker and Ostrom about warm blooded dinosaurs. But today the word about dinosaur feathers is spread not in books but on videos. Another cataclysmic change that sneaked up on me.

Interesting video of earth’s history and our possible future of climate change issues of warming seas and less fish because of lower oxygen levels in the oceans.

In which state oxygen is present in ocean or seas???? With reason

Let's not forget the glaciers during snowball earth, scraping all those minerals off the planet's surface and depositing that material in the oceans. My own theory is that this helped provide new sources of potential energy and chemical reactions for abiogenesys.

The fact is that all these great thinkers somehow totally forget about photodissociation, Hence if in fact the formation of the earth by any collision would have created massive heat. Then condensation would naturally occur from the cool down so hydrogen and oxygen would of been naturally formed. Please let me know if i'm missing something. Thus the atmosphere would naturally contain high amounts of photodissociation's particles. And water would of covered most of the young earth, is this not accurate? Given this scenario, how then can any proteins naturally occur? For we know D.N.A. needs proteins to read the proper sequences for assimilation. And we know protein in water is a death sentence for them. Please let me know where this natural process of abiogenesis came about.

does carbon dioxide cause increase in temperature or does increase in temperature cause an increase in carbon dioxide? Is the Milankovitch Cycle taken in consideration? There is a possibility that the global warming politics is wrong and the sun could be the major influence of temperature. Think about what 400 out of 1,000,000 actually represents.

'any additional release of CO2 so caused is dwarfed by the amount released by the burning of fossil fuels' Can you point me toward some conclusive, unfalisifiable data on this?

we were in a natural warming period. warming causes CO2 to rise. CO2 lags temperature.

TheMerowe if you want to talk large time scales, the position of the outer planets creating pull on our planets orbit as well as sunspot production are important considerations

Interesting that Genesis says the first thing creation of God was light when Einstein explained that the limiting factor of the physical universe is the speed of light. Coincidence? This science-believing Jesus follower thinks not… I argue with my climate change doubter fello Jesus followers that Gods giving us the dominion over creation implies that yes, we can indeed destroy the life supporting world he gave us…
