Rich countries built their wealth on fossil fuels that caused this crisis, so they bear responsibility for its victims. When rising seas and droughts force people to abandon their homes, it's not charity—it's reparations. We can't expect vulnerable nations to absorb millions of climate-displaced people while the beneficiaries of industrial pollution close their borders. Accepting climate refugees is the bare minimum of justice.
Countries have the right to control their borders and decide who enters, regardless of the cause. Taking unlimited climate refugees could destabilize receiving nations' economies, strain housing and services, and create political backlash that actually harms future refugee causes. Instead, global resources should go toward helping people adapt and rebuild in place—investing in drought-resistant crops, sea walls, and development in vulnerable regions is more efficient and respects national sovereignty.
