The Copernicus Sentinel-2B satellite takes us to the Republic of Fiji in the South Pacific Ocean on 28 September 2017. Part of Fiji’s largest island, Viti Levu, is pictured here, with coral reefs speckling the water.
Shaped by volcanic activity and earthquakes, the centre of the island is dominated by forests and a mountain range. The highest peak, Mount Tomanivi, reaches over 1320 m and is located on the central-right side of the image. While the area east of the mountain range receives heavy rainfall, the west side pictured here is in the ‘rain shadow’, meaning that the mountains block the rain clouds, leaving this area drier than the east.
In addition to the human population of some 600 000, one of the largest insect species also resides on Viti Levu: the giant Fijian long-horned beetle. The island is the only known home to the beetle, which grows up to about 15 cm long – excluding antennae and legs.
With more than 300 islands, the Fijian archipelago's low-lying coastal areas are at risk of sea-level rise – a devastating consequence of climate change. Satellites carry special instruments to measure sea-level rise – but not only. Different instruments can measure different climate variables, from greenhouse gases to melting glaciers, and offer a global view of the state of our planet.
The Republic of Fiji holds the presidency for this year’s COP 23 (Conference of the Parties) on climate, held this week and next at the UN Framework Convention on Climate Change headquarters in Bonn, Germany.
