Increasing Debates On Climate Engineering (Geoengineering)

Climate Engineering Discussions - Why Are They Increasing?

The inadequacy of current policies in combating climate change and the slow pace of efforts to reduce greenhouse gas emissions have brought the world to a contentious crossroads. As we approach 2035, it is predicted that the international community’s agenda will increasingly focus on climate engineering, particularly solar radiation management (SRM), measurable through the rising number of formal agenda items in climate negotiations, academic publications, and policy documents. This suggests that scientists and policymakers are seriously considering the idea of artificially lowering the planet's temperature alongside slowing global warming.

Why Are Current Climate Policies Failing?

Progress towards achieving the goals of the Paris Agreement falls short in the face of rising temperatures and extreme weather events. The gap between emission reduction commitments and actual implementation is fueling disappointment within the scientific community. Consequently, climate engineering is being added as a third pillar alongside mitigation (reducing emissions) and adaptation (adjusting to impacts).

Why Is Solar Radiation Management (SRM) Being Discussed?

Methods like SRM, which aim to reflect sunlight back into space by injecting aerosols into the atmosphere, raise serious ethical and governance uncertainties. These uncertainties contribute to the increased discussion of the topic, leading to an estimated probability of less than 85 percent, around 60 percent, due to a lack of a global decision-making mechanism. This means discussions will increase but full implementation will require more time and international consensus.

What Developments Are Expected By 2035?

The realization of this prediction would be a natural consequence of failing to achieve climate goals. By 2035, successive temperature records and sea level rise could drive governments towards radical solutions. The prominence of the geoengineering heading in academic publications and policy documents is expected to increase, and it will likely feature as an agenda item in international climate negotiations.

Frequently Asked Questions

What Is Climate Engineering?

Climate engineering (geoengineering) encompasses a broad range of techniques aimed at mitigating the effects of climate change by deliberately intervening in the planet’s energy balance. These techniques include solar radiation management (SRM) and carbon dioxide removal from the atmosphere (CDR).

Why Is Solar Radiation Management Controversial?

SRM aims to reflect sunlight back into space by injecting aerosols into the atmosphere. However, this method could have unknown side effects on the climate system, potentially leading to conflicts between countries, and may diminish interest in reducing greenhouse gas emissions. Furthermore, a global governance framework has yet to be established.

What Does The Increasing Discussion Of Climate Engineering Mean?

The increasing discussions indicate that scientists and policymakers are accepting that achieving current climate goals is becoming more difficult. This necessitates considering radical solutions; however, implementation will be slower due to ethical, legal, and political uncertainties. We estimate this trend of increased discussion has an approximate probability of 60 percent.
