Is human-caused climate change responsible for increasingly severe heat waves?

Context

Heat waves are becoming more frequent and intense across the globe, raising questions about their causes. Scientists increasingly attribute this trend to human-caused climate change, which warms the atmosphere through greenhouse gas emissions, though debate persists about the precise contribution of human activity versus natural climate variability. Understanding this link matters because it shapes policy responses to extreme heat, which poses serious risks to public health, agriculture, and infrastructure.
