A liquid oxygen airlift and dispersal at the lower stratosphere would address these six issues:
- Reduction and removal of synthetic greenhouse gases which are causing 80 ppm of CO2 equivalent warming to the planet.
- Ozone depleting substances removal or reduction.
- Thickening up the ozone layer, increasing needed UV protection by reducing the relative chlorine, fluorine and bromine fractions.
- Methane gas removal which appears to be becoming extremely urgent.
- Reduce acceleration of global warming and species extinction.
- Slow and may even reverse ice loss.
We have everything to gain and nothing to lose at this point as we wrestle with carbon emissions more slowly than we can afford to.
Cost: $50B, Size: 6 million Tonnes of oxygen over 5-10 years. Remember the other alternatives we have; the are toxic or take a very long time.
As we experience the massive release of methane from pockets in the permafrost and from methane clathrates now, the globe is going to continue to heat up. The only element that can remove this methane is oxygen, which we will have enough of to do it but the problem is that the methane caused warming will last for hundreds of years unless we remove it asap.
Almost half of the warming we have is caused by synthetic greenhouse gases (Prinn et al), which can be removed by oxygen if there is a concerted effort to use it by airlift to 18-22 Km. As methane is added, this warming is going to increase and could triple the warming and raise temperatures by a total of 6’C.
If we add geoengineering caused warming to this, by attempting to “shade” the Earth, it will put more heat trapping walls up to the heat that needs to escape. Any physical barrier would cause this, and this is why I think oxygen is preferable. Oxygen breaks down all of the greenhouse gases except CO2 and water. Chemicals being used for weather modification right now are halting precipitation in many areas, like California. Oxygen across the system does not force sacrifices like this, it allows heat release from everywhere once it is diffused into the environment.
If we do not focus on the real cause of global warming, our greenhouse gas problems, we are set to suffer more and more heat accumulation that no amount of geoengineering will significantly reduce. Aerosols simply will block the heat escape mechanism we need right now and for a significant period of time.
Humanity has the capacity to airlift anything now in vast quantities. Oxygen is available in our developed nations for this airlift protocol. We have proof in the fossil record that oxygen removes greenhouse gases and oxygen is relied upon to form all the oxidants which remove pollutants and gases from the atmosphere. We need to have this airlift computer modeled and discussed in public as the non toxic alternative to geoengineering with aerosols.
Dr. Peter Wadhams states in this presentation that the methane release will ultimately cost is $60 Trillion as global warming costs. $40-50 billion for a first oxygen airlift seems reasonable to work to avoid these direct costs as indirect costs are not yet calculable.
