What strategies can cities adopt to mitigate climate change impacts?

Cities can adopt strategies to mitigate climate change impacts by promoting renewable energy and enhancing public transportation. This approach is pivotal because transitioning to renewable energy sources—like solar, wind, and hydro—reduces greenhouse gas emissions, which directly contribute to climate change. By investing in renewable energy infrastructure, cities can decrease their reliance on fossil fuels and promote sustainable energy practices among their residents and businesses.

Additionally, enhancing public transportation offers a twofold benefit. It helps reduce the number of individual vehicles on the road, leading to decreased air pollution and lower carbon emissions. Efficient and reliable public transportation encourages residents to use alternative modes of transport rather than driving, which can lower overall traffic congestion and improve urban air quality. Such measures align with broader climate action goals by minimizing the city's carbon footprint and making urban living more sustainable.

The other strategies presented do not effectively address climate change mitigation. For instance, promoting fossil fuel usage and expanding highways would likely exacerbate emissions and traffic congestion. Similarly, reducing green spaces and increasing urban sprawl could lead to greater heat island effects and loss of biodiversity, which are counterproductive in managing climate impacts. Encouraging migration to rural areas does not directly engage with urban infrastructure and can create other challenges in those regions regarding sustainability and resource management. Therefore,
