ilmastoskeneereistä

Ilmastoskeneerit, also known as climate engineers or geoengineers, are individuals or groups involved in the concept of climate engineering, a broad term for large-scale intentional interventions in the Earth's climate system to counteract climate change. This field is highly speculative and encompasses a range of proposed technologies.

The primary goal of climate engineering is to reduce the effects of greenhouse gas emissions. Two main categories of proposed approaches exist. The first is solar radiation management (SRM), which aims to reflect a small fraction of sunlight back into space to cool the planet. Methods under consideration include stratospheric aerosol injection, marine cloud brightening, and space-based reflectors.

The second category is carbon dioxide removal (CDR), which focuses on removing carbon dioxide from the atmosphere. Techniques explored include afforestation and reforestation, bioenergy with carbon capture and storage (BECCS), direct air capture (DAC), and enhanced weathering.

While the theoretical potential of these technologies is recognized, significant scientific, ethical, and governance challenges remain. Concerns include potential unintended side effects on weather patterns, ecosystems, and regional climates, as well as the risk of moral hazard, where the prospect of geoengineering might reduce efforts to cut emissions. The development and deployment of climate engineering technologies are subjects of ongoing research and debate within the scientific community and among policymakers.
