This morning United Nations General Secretary Antonio Gutteres, currently in Tonga for this year's Pacific Islands Forum Leaders Meeting, presented new research showing that ocean temperatures in the Pacific are rising at 3 times the rate worldwide. This contributes to increased sea level rise, which in turn could result in some islands becoming uninhabitable within the next decade. Without cuts to global emissions, Mr Gutteres said, the Pacific Islands can expect additional sea level rise of 15 cm by 2050 and 30 days a year of coastal flooding. Mr Gutteres has called for global leaders to phase out fossil fuels and "massively boost climate adaptation investments" in vulnerable countries.
