Science for Action.


Understanding and predicting these complex interactions is critical to building effective early warning systems. While forecasting capabilities have advanced significantly, gaps remain in observation networks, forecasting accuracy, and access to high-quality climate and hydrological data. Strengthening National Meteorological and Hydrological Services (NMHSs) in developing nations is not only vital for climate adaptation—it is essential for global resilience, security, and economic stability. As the UN’s specialized agency for weather, climate, and water, WMO continues to harness the power of partnerships through its network of 193 Member States and Territories. Now is the time to act. By closing the early warning gap together, we can build a safer, more resilient world

State of the Global Climate 2025.

Image
   The Earth’s climate is more out of balance than at any time in observed history, as greenhouse gas concentrations drive continued warming of the atmosphere and ocean and melting of ice, according to the World Meteorological Organization (WMO) . These rapid and large-scale changes have occurred within a few decades but will have harmful repercussions for hundreds – and potentially thousands – of years. State of the Global Climate 2025 The global climate system is complex. In order to unpack such complexity, the WMO State of the Global Climate 2025 uses Climate Indicators to describe the changing climate. The following site aims to provide an overview of the annually produced State of the Climate report . Please note that for some indicators, 2025 data is not yet available. The latest available data is provided where this is the case. Greenhouse Gases Increasing levels of greenhouse gases, like carbon dioxide, in the atmosphere due to human activities are a major driver of...

Total Cloud Cover in Xinjiang Uygur Autonomous Region, Northwest China: A Comparison of ERA5 and ISCCP With FY4A.

Image
Cloud is an important factor affecting climate change , playing a crucial role in controlling the Earth’s energy and water cycle. In this study, total cloud cover (TCC) from the fifth-generation atmospheric reanalysis of the European Centre for Medium-Range Weather Forecasts (ERA5) and the International Satellite Cloud Climate Project H-series (ISCCP) were compared with those from the Advanced Geosynchronous Radiation Imager (AGRI) aboard Fengyun4A (FY4A) and ground observations (OBS), revealing the spatiotemporal distribution characteristics of TCC in Xinjiang Uygur Autonomous Region (Xinjiang), northwest China. The findings indicate that the interannual fluctuations in the annual mean TCC from OBS in Xinjiang exhibit no discernible trend, while those based on ERA5 and ISCCP demonstrate a decline. The TCC from FY4A and ISCCP shows a distribution pattern of high in the south and low in the north, whereas the opposite is true for that from OBS and ERA5. For all ground observation statio...
