UEF2026 kicks off in Reading today.

This year the focus at the annual forum for ECMWF forecast users lies on extreme temperature forecasts, from heatwaves to cold spells, and how advanced forecast products can help improve preparedness and resilience.

Did you know that the Methane Hotspot Explorer from the Copernicus Atmosphere Monitoring Service (CAMS) lets you see not only where methane is detected, but also the shape and extent of the resulting plumes?
Using observations from the Tropospheric Monitoring Instrument (TROPOMI) aboard the Copernicus Sentinel-5 Precursor, the app helps users explore plume behaviour in more detail, with a wind layer to support interpretation of transport and movement.

Users can also access key event information, including date, time, country, coordinates, emission rate, uncertainty and detection ID, and download the data for further analysis.

A new scoping study carried out under the Strengthening Early Warning in Africa (SEWA) initiative explores how impact-based forecasting and early warning systems could be strengthened across Sub-Saharan Africa.

Commissioned by ECMWF, the study provides a comprehensive assessment of the current landscape of early warning and impact-based forecasting initiatives across the continent. It examines how forecasts, exposure data and institutional coordination systems interact within the broader warning chain during severe weather and climate events.

The scoping study was conducted by a consortium led by HKV, together with the Netherlands Red Cross 510, Deltares and TAHMO Initiative. It is intended as a foundational step to help inform future activities under SEWA.

Did you know the Greenland Ice Sheet covers roughly 80% of the island and is one of only two ice sheets on Earth?

The European State of the Climate 2025 confirms the 29th consecutive year of net mass loss for the Greenland Ice Sheet:

🧊 In 2025, the Greenland Ice Sheet lost around 139 billion tonnes of ice. This is equivalent to about 1.5 times the ice stored in all glaciers in the European Alps and raised global mean sea level by 0.4 mm.

🧊The 2025 mass loss was 9% lower than the average of around 152 Gt per year, mainly because of higher‑than‑average spring and summer precipitation, which partly offset summer melt.

🧊 Since the 1970s, the Greenland and Antarctic Ice Sheets have together lost over 10,000 Gt of ice, contributing about 3 cm to global sea-level rise.

Dive into the findings in , published jointly by ECMWF and the World Meteorological Organization (WMO).

ECMWF’s annual innovation programme Code for Earth has entered its next phase, the Coding Phase, following the evaluation of all submitted proposals.

14 proposals were selected to move forward into the Coding Phase. Until the end of August, selected teams will work closely with mentors from ECMWF and challenge partners to develop and refine their solutions as open-source projects.

The programme will conclude with the Code for Earth Final Day, which will take place at ECMWF in Reading, UK, in September 2026.

Run every year since 2018, Code for Earth brings together innovators to collaborate with a community of experts in Earth sciences, computer science, artificial intelligence, and machine learning, developing open-source solutions using ECMWF data and technologies.

🐝 Today is , a timely reminder that these amazing insects are key to biodiversity. Climate change and air pollution affect habitats, influence ecosystem resilience and add stress to already vulnerable natural systems.

The Copernicus Climate Change Service (C3S) and the Copernicus Atmosphere Monitoring Service (CAMS), both implemented by the European Centre for Medium-Range Weather Forecasts (ECMWF), provide open climate and atmospheric data that help monitor these pressures across Europe and beyond.

From tracking climatic conditions such as temperature and precipitation to assessing ozone, particulate matter, and wildfire emissions, C3S and CAMS strengthen the evidence base for biodiversity assessment, conservation planning and ecosystem restoration.

As the European Union works towards its biodiversity goals, access to reliable data remains essential for informed action.
