Arnot Tong's efforts to deal with climate change.

Aino claims that by 2050, Kiribati Islands will no longer be suitable for human habitation due to rising sea level and salinization of fresh water caused by climate change. He has repeatedly made it clear that all Kiribati people will be forced to leave their homes and become climate refugees. In June 2008, Aino said that things "have reached an irreversible stage" and "it is painful to consider the possibility of leaving this country, but we have to do so."

Ainote's plan for nationals is to go to other countries to train their skills, so that Kiribati people can make some contributions to their communities after emigrating in the future, instead of just being "environmental refugees". At present, some Kiribati nurses and other technicians have gone to Australia and New Zealand for training, which is the first step of this plan.

No country responded to Kiribati's immigration plan. Only former Zambian President Mwanawasa once said that Zambia had enough space for Kiribati immigrants to live, but he died suddenly in August 2008.

In 2008, the Kiribati government announced the establishment of a nature reserve in the Phoenix Islands, prohibiting all development activities, and then the place was listed on the United Nations World Heritage List because of its rare and complete biodiversity. Arnot Tong has been advocating that the world's major polluters hold meetings and dialogues with Kiribati, Marshall Islands and Maldives.
