Which of the following would be considered a climate change adaptation strategy?

A climate change adaptation strategy focuses on adjusting practices, processes, and structures to minimize the negative impacts of climate change and enhance resilience. Protecting coastlines from erosion is an essential adaptation strategy because rising sea levels and increased storm intensity due to climate change can lead to significant coastal erosion. By implementing measures such as constructing barriers, restoring natural habitats, and reinforcing shorelines, communities can safeguard infrastructure, ecosystems, and livelihoods from the adverse effects of climate change.

In contrast, releasing sunlight-reflecting aerosols to reduce temperatures is a geoengineering approach aimed at climate mitigation rather than adaptation. Retrofitting buildings to become more energy efficient and developing clean cooling systems, while beneficial for reducing greenhouse gas emissions and energy consumption, primarily serve as mitigation strategies to address the root causes of climate change rather than adjusting to its impacts.
