Record Heat in Greenland and Iceland: Impacts on Global Ocean Circulation

Record-Breaking May Heatwave

• 🌡️ Greenland and Iceland experienced an absolute record-breaking heat event in May, with Iceland having its hottest week ever for that month.
• 🌍 Even in the current climate, this extreme heat is considered relatively rare.

Human Impact on Arctic Temperatures

• 🔥 Without human-induced climate change, such an event would have been virtually impossible.
• 📈 Temperatures increase more significantly the further one moves from the equator, with the Arctic Circle seeing temperature increases of 3-4°C, compared to the global average of 1.3°C.

Global Consequences of Ice Melt

• 🧊 The study highlights the melting of the Greenland ice sheet as a direct consequence of this extreme heat.
• 🌊 This melting has significant potential impacts on global ocean circulation, indicating that such extreme events affect the entire world.
