Climate change is one of the most pressing global challenges of the 21st century, with an increasingly visible impact on sea and ocean levels. While a 1°C increase in global temperature may seem insignificant, its consequences are serious and affect everyone, especially coastal communities. Melting glaciers and rising temperatures are contributing to soaring water levels, which could result in the disappearance of many island countries from the world map by 2050. The Maldives, Kiribati and, in fact, almost every Pacific island could soon face serious consequences from rising sea levels. It is estimated that these islands are home to around 3 million people within just 10 km of the coast – there is a real threat that they will have to leave their homes before the end of this century. Moreover, sea level rise has already caused the disappearance of at least five reef islands that belonged to the Solomon Islands.
