Global Climate Records Keep Falling, Says UN Weather Agency

The World Meteorological Organization, the United Nations agency responsible for monitoring global weather and climate, has released a summary of key climate indicators drawn from data collected in 2025 and 2026. The findings point to a continued and accelerating pattern of climate breakdown, with records being broken across multiple measures simultaneously.

Global average temperatures have continued to rise, pushing further beyond the thresholds set by the 2015 Paris Agreement, which aimed to limit warming to 1.5 degrees Celsius above pre-industrial levels. The WMO's compiled reports confirm that recent years rank among the hottest ever recorded in human history.

Ocean warming is another critical marker highlighted in the reports. The world's seas absorb a large share of the excess heat trapped by greenhouse gases, and rising ocean temperatures have wide-ranging consequences. These include the bleaching of coral reefs, disruption to marine food chains, and the intensification of tropical cyclones. For an island nation like Mauritius, situated in the South-West Indian Ocean, warmer seas directly influence the strength and behaviour of cyclones during the summer season.

Glacier retreat is also accelerating, according to the WMO data. Ice sheets and mountain glaciers around the world are shrinking at rates that scientists describe as unprecedented in the modern record. This contributes to rising sea levels, which threaten low-lying coastal areas and small island states worldwide.

The WMO compiles these indicators from thousands of observation stations, satellites and ocean buoys across the planet, making its reports among the most authoritative global benchmarks available to governments and policymakers.

What this means for Mauritius: the island is particularly exposed to the effects described in this report. Sea-level rise threatens coastal infrastructure, beaches and the tourism industry that the country depends on. More intense cyclones pose risks to homes, agriculture and livelihoods. Coral bleaching endangers the reef systems that protect shorelines and attract visitors. Local authorities and the Mauritius Meteorological Services have been tracking these trends closely, and the broader global picture presented by the WMO underlines the urgency of regional adaptation planning.

The accumulation of climate records is not simply a scientific footnote. It represents a steady narrowing of the window for action, both globally and for small island nations in the Indian Ocean that are among the most vulnerable to its consequences.
