Is too much carbon dioxide the problem? Or is too little oxygen? These are articles about climate change, in particular, global oxygen depletion, that will leave you feeling breathless.

This article is more for scientists and field researchers. A practical step forward in determining global oxygen depletion rates. A conclusion to decades of research.
Have you ever wondered how much breathable air is on Earth, and if we'll ever run out? Our atmosphere is paper-thin relative to a basketball, and we use its oxygen to power internal combustion engines, create electricity, and manufacture products (cement, chemicals, plastic). Worse, we are destroying the plants that make more breathable oxygen.
I calculate how much oxygen a tree breathes and how much excess oxygen a tree produces in three different ways. Spoiler alert: It's not a lot.
Ten reasons why we might be measuring oxygen in the atmosphere wrong. And how global oxygen depletion may be a hidden driver of climate change.
I demonstrate how to calculate the mass of oxygen in the atmosphere. And I talk about ten reasons why the accepted values may be wrong.
What if the driver of climate change is NOT carbon dioxide but oxygen depletion? See the math to compare CO2 emissions to oxygen burned.
There are many ways oxygen is burned/consumed/oxidized. It is a very reactive element. We highlight the major natural causes, like: respiration, decomposition, forest fires, rust and more.
There is a growing discontent between classes and the battle between greed and altruism -- the American Dilemma. This article is about a third option.
This graph illustrates the exponential growth of the human race and the consumption of non-renewable resources. The question isn't if the population will stop growing/consuming, but when?
Here's an exercise in thinking positive using the BP oil spill as an example. Also, it seems one of the byproducts of traveling the world is a desire for social activism, because I never imagined thinking of stuff like this.
We are all aware of our reliance on fossil fuels and their byproduct of greenhouse gases and poisons. But have you ever wondered about the oxygen needed to burn the fuel?
As mankind burns more and more fuel, we are also burning more and more oxygen. Simultaneously, the Earth's ecosystem is being destroyed. At what point does the Earth reach a tipping point? And, how long before we run out of air to breathe?
