World Meteorological Organization has published the State of the Global Climate 2023 report.

Among the key messages of the report:

• 2023 was the warmest year on record, with the global average near-surface temperature at 1.45 °Celsius above the pre-industrial baseline. It was the warmest ten-year period on record.
• The global set of reference glaciers suffered the largest loss of ice on record (since 1950), driven by extreme melt in both western North America and Europe.
• Antarctic sea ice extent was by far the lowest on record.
• The number of people who are acutely food insecure worldwide has more than doubled, from 149 million people before the COVID-19 pandemic to 333 million people in 2023 (in 78 monitored countries by the World Food Programme).
• In 2023, renewable capacity additions increased by almost 50% from 2022, for a total of 510 gigawatts (GW) – the highest rate observed in the past two decades.
