Geoengineering is the deliberate large-scale intervention in the Earth's climate system to moderate climate change. The main type of geoengineering is solar radiation management (SRM) and its objective is to reduce the amount of solar radiation that reaches the Earth, in order to try to reduce its temperature.
There are a number of problems with geoengineering, both technical and ethical. Some of the technical issues include:
The problem is that there is great uncertainty about the effectiveness of geoengineering. We do not fully understand how geoengineering would interact with Earth's climate system, and there is a risk that it could have unintended consequences. For example, SRM could alter rainfall patterns or lead to an increase in the frequency of extreme weather events.
The difficulty of implementing geoengineering on a large enough scale. SRM would require the deployment of large amounts of materials into the atmosphere, which would be expensive and technically challenging, with unforeseen results.
And there is also the risk that geoengineering will be used as a substitute for reducing emissions, and that some will try to use geoengineering as a way of avoiding the need to reduce greenhouse gas emissions. This would be a dangerous bet, as geoengineering is not a permanent solution to climate change and could have unintended consequences.
And there are also a number of ethical issues, as the effects of geoengineering would not be evenly distributed and there is a risk that some countries or groups of people will benefit more than others. For example, SRM could benefit some countries and harm others.
Geoengineering presents risks to the environment, and could have a number of unintended consequences for our environment, such as the alteration of ecosystems or the extinction of species.
In general, there are a number of serious problems with geoengineering, and it is important to carefully consider these problems before considering geoengineering as a solution to climate change.
Given the potential problems with geoengineering, it is important to proceed with caution. Geoengineering should only be considered as a last resort, and only after all other options have been exhausted. It is also important to develop international agreements on the governance of geoengineering, in order to minimize risks and maximize potential benefits.
That is why the tests carried out by some companies such as OPEX, Make Sunsets and others, which send balloons into the stratosphere to launch sulfur dioxide particles there, with the aim of reflecting the sun's rays and trying to lower the ambient temperature of the atmosphere, are nonsense.
And as these actions could increase, the European Commission is promoting the agreement between countries to control unilateral actions by individuals that may cause unknown and hardly predictable damage.
It is to be hoped that these European actions have positive results, and that governments are aware that they cannot act unilaterally, and what is worse, without knowing the results that these actions can cause.
