How to beat Global Warming if you have Nothing

For years we have tried to alert people to the dangers of a post peak oil climate fight, meaning the task of fighting climate change with very little productive resources, because the oil distribution system has more or less collapsed. Our current attempt to respond to global warming within the economy is just inviting this situation to come about, because the economy as a whole will do 90% by wasting fossil fuel and maybe 10% of the fuel will be turned in to renewable sources that multiply the fossil input by a factor 6 or more. The economy is the problem it can not be part of the solution.

If it is possible to cordon off resources to fight climate change from the fossil fuel pool this would be fine, it would not take any money, only the resolve of politics, and it would cost banks a dear sum of lost profit from fossil fuel cashflow. Banks have to be overruled by politics, and this is hard in our modern corrupt political systems.

If there is no way to win from the banking/fossil fuel cartel there are still ways to win the climate fight, but these have to be minimally resource dependent. They will be labour intensive no doubt. We don’t know all of them but it seems a good idea to start thinking of them.

Trees

Easiest of them all is planting trees. Even though it is said that trees are darker and can warm up our atmosphere it is still better in the long term to do it, but it needs to be done with no economical objective. We believe that closely planted trees are a better strategy than planting trees at wide distances, because of the shade and micro climate trees can create. Colder air stays down, and this way water can be retained in the soil that would otherwise evaporate.

There’s quite a lot of land mass that is unpopulated, unused for farming and still able to sustain trees, and these should be planted aggressively.

Hydrologic interventions

On land the run of rain and flood water can be changed so that water is stored underground and doesn’t flow away to the oceans. This can be done also by freezing water with ambient air as is done in the Himalayan mountains. We have written here about contour trenching, done to allow flood water to sink into the soil instead of washing over it. This is a great way to improve ground water levels, which can then drive tree growth.

We think that above ground storage of floodwater either within walls or plastic containers can also work. The barriers that hold 1 meter of water do not need to be extremely strong, yet the total volume held that way can be very large.

We think that heating sand using solar energy can enable the building of water retention and distribution structures without the need for heavy  material logistics.

We think that well drilled in regions with aquifers (which also occur in f.i. the Sahara desert) can be an enabler of afforestation projects that can in turn change the regional temperatures.

We think that flooding salt flats with ocean water is a good way to increase humidity, even though this can also have a negative effect in regions that will become to hot to survive in. This can include digging canals or waterways.

Ocean Nutrition and Oxygen

Oceans can be a great CO2 sink, but currently they are actually losing that function because of too much CO2. The changes in PH are bad for plant life, such that the more acid the oceans get, the less it can remove it from the atmosphere. Also the warming of ocean water makes them less able to retian gasses like CO2 and O2. All these factors are moving our oceans to catastrophic release of gasses, methane, their death and ultimately their role as a source of toxic H2S.

To fight this we need to use all the potential available. We can perhaps use underwater obstructions to drive deep ocean water to the surface, where its nutrients (from which the top layer is usally depleted) can allow plant growth. Japan has experimented with this with success. As long as the ocean currents exist (They will stop once the oceans are more uniform in temperature) they can be used to enable carbon capture. Ocean life has a tendency to lose carbon which will sink to the bottom. There it can remain in an anoxic environment, so carbon can actually be stored.

We think covering large parts of the ocean with white plastic to reflect sunlight may help keep our planet cool. This sounds like a costly solution but there is a lot of plastic out there, so barges that process it and turn it into floating albedo shields may be a good idea.

We also have written here about the possibility of floating farms, floating on bamboo rafts. Of course recycled plastic rafts can help. Such farms can grow fish, Kelp, seaweed, algae, but also land crops once they reach sufficient height. We would like to see countries like the Phillipines investigate this option as they have a large undersea undeep shelve they can havest from.

A german study calculated the option of increasing algae growth using deep ocean nutrients using wave driven pumps to get the water to the surface. This would cool the air, lead to more growth of plants on land and have a 10% annual carbon reduction impact if continued as long as needed.

It may be possible to use salt to create a highly reflexive surface that can be floated on sea or laid down on land. It seems vitaly important to slow down warming of Arctic ocean waters and Russian permafrost. In agriculture white plastic is used to cover vast areas of land, and this may be a good way to keep the permafrost cool, and the escaping methane may be captured and used in the process of covering.
