Seen from above, it's easy to see why the Southwest Pacific country of Tuvalu has been identified as one of the world's most vulnerable nations to climate change. The country is made up of a collection of small islands and coral atolls, totalling only 27 square kilometres, scattered over 500,000 square kilometres of ocean. The highest point throughout the country is only 5 metres above sea level, resulting in special vulnerability to sea level rise. According to the Tuvaluan government, "since 1993, sea level near Tuvalu has risen about 5mm per year; this is larger than the global average." Other challenges face the country including drought, ocean acidification and waste problems. Tuvalu. March, 2019.
