The idea of blocking the sun’s rays as a way to combat Climate change is gaining traction, but experts warn of the broad and potentially inequitable impacts of solar geoengineering. While limiting the amount of sunlight that reaches the Earth could rapidly cool the planet, it would not address other climate harms caused by burning fossil fuels. Furthermore, it is uncertain how solar radiation management (SRM) would affect weather patterns around the globe, and different regions could be impacted in different ways.
One of the major concerns with SRM is that research into it is primarily being conducted by wealthy countries, which threatens to exacerbate the growing divide between those who contribute most of the emissions warming the planet and those who bear the brunt of its impacts. Therefore, it is crucial that research on SRM includes countries that are already vulnerable to Climate change.
According to a report by the United Nations Environment Programme, any research on SRM must consider potential risks and involve countries that are most vulnerable to Climate change. The report calls for regulations to manage SRM’s potential risks, with a focus on ensuring that the process is fair and equitable. The aim is to advocate that “the research actually addresses the risks and uncertainties and the potential environmental, social, and economic and other risks that may result from deployment in these technologies.”
The debate over the need for further research into SRM has grown as the world barrels toward breaking temperature limits that could result in a cascade of climate devastation. While some proponents of climate action argue that SRM detracts from the need to reduce planet-warming Pollution, others say more research is needed to understand how or even if it can be implemented safely. This means taking a more inclusive approach to SRM studies.
However, researchers in the Global South often struggle with a lack of reliable electricity and internet access, as well as a shortage of training opportunities. The funding for research in the Global South is also much lower than what is provided by wealthy countries. As a result, initiatives like the Degrees Initiative, which provides funding for research into SRM impacts in developing countries, are essential for building up a community of scientists who can inform policy, ethics, and governance.
Solar geoengineering is not a silver bullet to combat Climate change, and more research is needed to understand its potential risks and benefits. Furthermore, research must be conducted in an inclusive manner that considers the needs and concerns of vulnerable communities. It is crucial that we invest in research in the Global South and work towards building a global community of scientists who can inform policy, ethics, and governance. Only then can we ensure that any action taken to address Climate change is fair and equitable. So, let us all take a step towards a sustainable future by supporting research and initiatives that prioritize inclusivity and global cooperation.
