Weather Eye with John Maunder

We live on an interconnected planet. We share one Earth, with one atmosphere and one ocean.

Our weather and climate and the water cycle know no national or political boundaries. International cooperation is essential.

This philosophy has driven the work of the world's meteorological community since 1873 and will guide us as we translate science into services for society for present and future generations.

World Meteorological Day 2023 takes place during WMO's 150th anniversary. It highlights past achievements, present progress and future potential - from the late 19th century telegraphs and shipping forecasts to supercomputers and space technology.

Throughout this time, National Meteorological and Hydrological Services have worked around the clock to collect and standardise data which underpin the weather forecasts we now take for granted. The history of WMO data exchange is a remarkable story of scientific vision, technological development and, most of all, of a unique system of cooperation to serve society.

The anniversary also serves as a reminder of our changing climate. The International Meteorological Organization – the predecessor of the World Meteorological Organisation – was established in 1873 in an era when pollution from industrial and human activities was at its beginning.

As a result of heat-trapping greenhouse gases, the average global temperature is now more than 1° Celsius higher today compared to 150 years ago. Our weather is more extreme, our ocean is warmer and more acidic, sea levels have risen and glaciers and ice are melting. The rate of change is accelerating. We need urgent action now to slash emissions and to ensure that future generations can both survive and thrive on our planet.

The good news is that rapid scientific and technological advances have greatly improved the accuracy of weather forecasts and life-saving early warnings. Big data is being exchanged more freely among a wider community than ever before, and there are new tools including machine learning and Artificial Intelligence.

There has been significant progress to monitor, simulate and project the global climate to support decision-making.

Our weather, climate and water cycle will be different in the future than in the past. Weather, climate and hydrological services will help us tackle the associated challenges and seize the opportunities.

Since 1961, the World Meteorological Organisation has been celebrating World Meteorological Day with a different theme selected for each year.
