The Urgency of Including the Global South in Solar Geoengineering Discussions

As the climate crisis intensifies, the concept of solar geoengineering—specifically, the deliberate reflection of sunlight to cool the planet—has gained traction as a potential solution. However, the inclusion of voices and perspectives from the global south in discussions about these technologies is deemed critical to ensure equitable outcomes.

The climate crisis is reaching critical thresholds, prompting discussions around solar geoengineering techniques such as stratospheric aerosol injection and marine cloud brightening. While proponents argue these methods could provide temporary relief from rising temperatures, critics caution against the unknown risks and potential for exacerbating existing inequalities. The global south, which is disproportionately affected by climate change, remains largely excluded from these conversations, raising concerns about climate justice and governance.

Organizations like the Degrees Initiative are beginning to address this gap by funding scientists from the global south to investigate the implications of solar geoengineering in their regions. Similarly, the UK’s Advanced Research and Invention Agency is supporting research into the governance and ethics of geoengineering approaches. Despite these efforts, funding and public debate remain limited, highlighting the urgent need for more inclusive research initiatives.

Excluding the global south from solar geoengineering discussions risks perpetuating colonial dynamics in climate policy, where solutions are designed without local input. This exclusion could lead to geopolitical tensions and exacerbate climate injustices, as the benefits and harms of geoengineering may not be evenly distributed. Comprehensive research is essential to identify who stands to gain or lose from these technologies.

Advocates for including the global south emphasize that engagement in solar geoengineering discussions does not equate to endorsement. Instead, it is about empowering local communities to critically assess potential benefits and risks. The call for a transparent governance framework is echoed by various stakeholders, emphasizing the need for equity and informed consent in any geoengineering initiatives.

Critics argue that solar geoengineering is not a viable long-term solution, as it does not address fundamental issues such as ocean acidification or fossil fuel dependence. They warn of the significant risks associated with unintended consequences, political misuse, and the abrupt termination of geoengineering projects. The sentiment is that ignoring the potential of solar geoengineering will not eliminate its risks; rather, a transparent and inclusive approach is necessary.

Moving forward, it is essential to foster research networks rooted in southern universities and to secure funding that promotes collaboration among countries in the global south. A global governance framework that prioritizes equity and transparency must be established to ensure that any discussions surrounding solar geoengineering are inclusive and reflective of diverse perspectives.
