Climate Update (Portugal & Europe): The EU’s Copernicus monitor says May 2026 was the world’s second-hottest on record, driven by an unusually early “heat dome” that pushed “feels-like” temperatures to 35–40°C across parts of western Europe, including Portugal—raising risks for people, crops and ecosystems during the growing season.

Ocean & Climate Signals: Scientists report the Atlantic’s overturning circulation may be weakening in ways that could make North Atlantic salinity swings far more extreme—an added stressor for Europe’s climate system. Biodiversity & Land Use (context): A data roundup ranks Europe’s most forested countries, with Finland leading—useful background as climate and wildfire risks grow.
