The island of Lampedusa in Italy offers an unique setting for greenhouse gas monitoring📍🇮🇹 By comparing ghg data from the ICOS station Lampedusa with monitoring stations around the world, scientists can identify long-term trends to support climate mitigation. 🌍 👉 https://ow.ly/fyP650ZoQEM

#ExploreICOS: Monitoring the Mediterranean's changing climate at Lampedusa island

Lampedusa, a tiny Italian island in the heart of the Mediterranean, is best known as a first stop for refugees fleeing North Africa. Beneath its turbulent reputation, the rugged island carved by wind and waves, is also a critical node in the ICOS greenhouse gas monitoring network.Sitting at the cape of a dramatic cliff under a gazing sun, the Lampedusa Observatory is overlooking eternal azur blue sea in all directions.

Western Europe is in the grip of a record heatwave and ICOS DG Hannele Laine told Yle News what the numbers mean: "The extraordinary gap between current temps and what is normal for late June in many regions is a stark reminder of climate change." 📰 Yle article (In Finnish): yle.fi/a/74-20232615

Länsi-Euroopassa kärvistellään nyt tukalassa kuumuudessa – ”Ei ehkä noille alueille kannata lähteä”, sanoo meteorologi

Monissa Länsi-Euroopan lomakohteissa on nyt tukalan kuumaa. Ranskassa voidaan huomenna tehdä kaikkien aikojen lämpöennätys.
