World Meteorological Organisation & Met Office: Global Annual to Decadal Climate Update

The Global Annual to Decadal Climate Update is issued annually by the World Meteorological Organization (WMO). It provides a synthesis of the global annual to decadal predictions produced by the Met Office and other designated centres around the world for the period 2025-2029. 

This report makes a number of probabilistic predictions about global mean near-surface temperatures, including:

• Forecast chance of one of the next five years being warmest on record
• Forecast chance of one of next five years, and entire five-year period, being above 1.5°C above the 1850-1900 average
• Arctic warming
• Regional precipitation patterns

Journalists came to this online briefing to hear authors of the report brief the journalists on their conclusions and what they mean for climate change.

Speakers included:

Prof Chris Hewitt, Director of Climate Services, WMO

Prof Adam Scaife, Head of Monthly to Decadal Prediction, Met Office Hadley Centre

Dr Leon Hermanson, Senior Scientist in Monthly to Decadal Prediction, Met Office Hadley Centre
