Climate change could force 1 billion from their homes by 2050

Global warming could trigger mass migration on unprecedented levels, with as many as one billion people losing their homes by 2050, scientists and political leaders on Tuesday were warned at a conference in London.

Hundreds of millions could be forced to migrate because of water shortages and crop failures in most of Africa, as well as in central and southern Asia and South America, the conference in London was told.

Rising sea levels could also cause havoc, with coastal communities in southern Asia, the Far East, the south Pacific islands and the Caribbean seeing their homes submerged.

The conference heard a warning from the UN High Commissioner for Refugees (UNHCR) that the developed world should start preparing for a huge movement of people caused by climate change.
