Preparation for climate displacement too slow, experts say

DURBAN, South Africa (AlertNet) – Climate impacts such as worsening droughts, flooding, storm surges and sea level rise could displace tens of millions of people by mid-century, scientists predict. But national and international rules governing resettlement of forced environmental migrants, and how they will be treated under the law, remain at a worryingly early stage, migration experts said at the U.N. climate talks in Durban. “This risk, while recognised, has been inadequately dealt with by the international community,” admitted John Crowley, who heads the ethics of science and technology section at UNESCO, the body that currently chairs the Global Migration Group, a U.N. interagency group on migration issues. Under today’s international law, “climate refugees” as a category are not formally recognised, and as such they have no right to asylum or other assistance. But an agreement at the U.N. climate summit in Cancun last year for the first time urged countries to accept that “climate change-induced displacement, migration and planned relocation” should be considered in plans to adapt to climate change. That may open the door to migration costs being funded under the emerging Green Climate Fund, which is expected to disperse a promised $100 billion a year, starting in 2020, for climate adaptation and emissions reduction efforts in the world’s most vulnerable nations, said Koko Warner, an expert on environmental migration issues at the U.N. University. Still, planning for predicted large-scale migration as a result of climate impacts remains preliminary, particularly regarding the politically perilous issue of migration across national borders. Lack of preparation doesn’t mean migration won’t happen, however, experts warned. “In some countries, there is no space (to resettle migrants), some countries might even go down under the water (and) in others, population pressure is so high that people cannot move (elsewhere in the country),” noted Qazi Kholiquzzaman Ahmad, a Bangladeshi economist and contributing author to several Intergovernmental Panel on Climate Change (IPCC) reports. “Therefore, it’s extremely important we find ways of moving them out of the country and into regional countries if possible, or into countries where the number of people is small and there is huge land area,” he said. He admitted that “this is a difficult subject”. One particular difficulty in dealing with climate-induced migration is that much of it is likely to be gradual. In many cases, it is predicted to be the result of an increasing burden of problems – poor harvests, bad weather, insufficient income – that make it difficult for families to stay in their homes, rather than the result of a single disaster, something international agencies are more practiced at addressing. “We are good at emergency response but bad on progressive, gradual phenomenon,” UNESCO’s Crowley said. “And climate change will be largely a progressive, gradual phenomenon. There won’t be anything to launch an appeal for, no specific event. There will just be growing pressure to migrate.” […]

CLimate displacement is a very complicated issue
Let me write a few comments on legal and social context.
While the Earth has always endured natural climate change variability, we are now facing the possibility of irreversible climate change in the near future. The increase of greenhouse gases in the Earth?s atmosphere from industrial processes has enhanced the natural greenhouse effect. This in turn has accentuated the greenhouse ?trap? effect, causing greenhouse gases to form a blanket around the Earth, inhibiting the sun?s heat from leaving the outer atmosphere. This increase of greenhouse gases is causing an additional warming of the Earth?s surface and atmosphere. A direct consequence of this is sea-level rise expansion, which is primarily due to the thermal expansion of oceans (water expands when heated), inducing the melting of ice sheets as global surface temperature increases.
Forecasts for climate change by the 2,000 scientists on the United Nations Intergovernmental Panel on Climate Change (IPCC) project a rise in the global average surface temperature by 1.4 to 5.8°C from 1990 to 2100. This will result in a global mean sea level rise by an average of 5 mm per year over the next 100 years. Consequently, human-induced climate change will have ?deleterious effects? on ecosystems, socio-economic systems and human welfare.At the moment, especially high risks associated with the rise of the oceans are having a particular impact on the two archipelagic states of Western Polynesia: Tuvalu and Kiribati. According to UN forecasts, they may be completely inundated by the rising waters of the Pacific by 2050.According to the vast majority of scientific investigations, warming waters and the melting of polar and high-elevation ice worldwide will steadily raise sea levels. This will likely drive people off islands first by spoiling the fresh groundwater, which will kill most land plants and leave no potable water for humans and their livestock.
Low-lying island states like Kiribati, Tuvalu, the Marshall Islands and the Maldives are the most prominent nations threatened in this way.“The biggest challenge is to preserve their nationality without a territory,” said Bogumil Terminski from Geneva. The best solution is continue to recognize deterritorialized states as a normal states in public international law. The case of Kiribati and other small island states is a particularly clear call to action for more secure countries to respond to the situations facing these ‘most vulnerable nations’, as climate change increasingly impacts upon their lives.
