Climate change poses a profound environmental challenge that will leave no country or community untouched. Its social impact, if unaddressed, will reinforce inequalities, deepen poverty and leave the world’s most marginalized populations in greater insecurity. Minorities and indigenous peoples are already living with its consequences, from rising sea levels and higher temperatures to increasingly frequent extreme weather events such as severe storms. Their isolation and exclusion in many countries leave them disproportionately exposed to these negative effects.
