Climate refugees 2.0 are emerging as a defining humanitarian and urban challenge of this century. As rising seas swallow coastlines and smart-city expansion pushes low-income communities to the margins, millions face forced displacement without clear legal protection. These climate-displaced people often fall through the cracks of refugee law, urban planning, and national policies. They cannot be considered as traditional refugees nor as sufficiently addressed by climate or developmental structures. The new wave of climate migration evokes some urgent questions: who is to blame, how they should be sheltered, and what should be done by the cities, states, and international institutions? For Latest News on Human rights and trends.
Who Are Climate Refugees 2.0?
Climate refugees 2.0 are people displaced not only by rising seas, floods, and extreme weather, but also by rapid smart-city expansion and climate-smart infrastructure projects. Governments construct new tech infrastructures, elevated roads, and waterfront realities that push out coastal inhabitants, fisherfolk, farmers, and urban slum communities as part of the so-called resilient or green. They do not cross borders often in large numbers as is the case with conventional refugees and thus they are not very visible in international disputes and statistics.
Rising Seas, Sinking Homes
The increasing sea levels are gradually washing away the coastline, saltifying ground-water, and demolishing homes, farms and all livelihoods. Whole settlements are to be resettled in low lying islands and delta areas, often to some already densely populated urban fringes. These climate refugees 2.0 typically receive limited compensation, weak relocation support, and no long-term social security. Women, children, and marginalised people are the worst sufferers as the disaster is slowly unfolding and causing them to become more impoverished, more at risk of illness, and deprived of cultural identity associated with land and sea.

Smart-City Expansion and Invisible Displacement
Smart-city expansion can unintentionally fuel climate displacement. During the retrofitting of cities with smart grids, metro lines, ocean roads and luxury housing, there is the clearing of informal settlement and working class neighbourhoods under the guise of development or resilience. The residents are either relocated to remote house blocks that do not have good services or they are left to self settle. This development-induced displacement creates a new category of urban climate refugees, whose eviction is justified through climate adaptation language but lacks meaningful participation, rights, or safeguards.
Who Should Protect Climate-Displaced People?
Protection of climate refugees 2.0 demands stronger national laws on climate migration, fair resettlement policies, and more inclusive smart-city planning. The governments should map vulnerable regions, ensure housing and livelihoods, and engage communities in decision-making. The international bodies may establish standards of climate displacement, and cities should impose rights-based relocation policies and climate-related and affordable housing. These steps will make climate justice and urban resilience incomplete without them.
