State of the Climate in the South-West Pacific 2022

18 August 2023

Weather-related disasters and climate change impacts are unraveling the fabric of society in the South-West Pacific. Sea level rise threatens the future of low-lying islands whilst increasing ocean heat and acidification harms vital and vulnerable marine ecosystems, according to a new report from the World Meteorological Organization (WMO).

The State of the Climate in the South-West Pacific 2022 report provides a snapshot of climate indicators including temperatures, sea level rise, ocean heat and acidification, and extreme weather events in 2022. It also highlights the socio-economic risks and impacts on key sectors like agriculture.

The report, along with an interactive story map, is one of a series of five regional reports and a global report from WMO providing the latest climate insights to inform decision-making.

The three-year-long La Niña event had a clear influence on temperatures in 2022. But despite its temporary cooling influence, it was still a warm year for the region. The mean temperature in 2022 was 0.2 °C to 0.3 °C higher than during the last strong La Niña event in 2011.
