Frequently forgotten in the global discussions and agreements on climate change are children and young people, who both disproportionately suffer the consequences of a rapidly changing climate, yet also offer innovative solutions to reduce greenhouse gas emissions (climate change mitigation) and adapt to climate change. Existing evidence is presented of the disproportionately harmful impact of climate-induced changes in precipitation and extreme weather events on today’s children, especially in the Global South. This paper examines the existing global climate change agreements under the UN Framework Convention on Climate Change for evidence of attention to children and intergenerational climate justice, and suggests the almost universally ratified Convention on the Rights of the Child be leveraged to advance intergenerational climate justice.
