🗞️ Driving the news: Southern Europe is enduring a major heat wave, with temperatures surpassing 100°F (38°C) across Portugal, Spain, France, Italy, and Greece
• Portugal is forecast to reach 109°F (43°C) in Beja and Évora, while parts of Spain could hit 107°F (42°C)
• Authorities are issuing heat alerts and fire warnings as two intense air masses — one from Africa and another from the U.S. — converge over the continent

🔭 The context: This is the first significant heat wave of the European summer, intensified by a marine heat wave in the Mediterranean — one of the planet’s largest thermal anomalies
• Past years have seen a 30% increase in heat-related mortality across Europe, prompting public health interventions like free swimming access in Marseille and labor restrictions in Sicily during peak heat hours

🌍 Why it matters for the planet: The lengthening and intensifying of heat waves signal a broader climate crisis, with summers starting earlier and ending later
• The compounding impacts of marine and atmospheric heat threaten biodiversity, increase wildfire frequency, and challenge public health systems, particularly for vulnerable populations

⏭️ What's next: Record-challenging temperatures are forecast in Paris and Berlin, with heat persisting into early July
• The World Meteorological Organization warns of an 80% probability that at least one year between 2025 and 2029 will surpass 2024 as the hottest on record, highlighting an urgent need for climate adaptation across Europe’s infrastructure, labor policies, and public health planning

💬 One quote: “We have just experienced the ten warmest years on record,” said Ko Barrett, Deputy Secretary-General of the World Meteorological Organization
“This WMO report provides no sign of respite... growing negative impact on our economies, our daily lives, our ecosystems and our planet”

📈 One stat: By 2050, over 5 billion people are expected to endure at least one month of extreme heat annually — more than double the exposure from the year 2000
