🗞️ Driving the news: New scientific data indicates that last summer's temperature rise in the northern hemisphere may have been significantly higher than previously thought, exceeding the 1.5C target set by world governments

🔭 The context: Researchers found that the average temperature last summer in Europe, North America, and Asia was 2.07C higher than the 1850-1900 reference period
• However, this reference period may have been cooler than recorded due to improperly positioned weather stations

🌍 Why it matters for the planet: If historical temperature baselines are lower than estimated, the current global warming situation is more severe, implying a greater urgency for climate action to mitigate impacts on ecosystems and human societies

⏭️ What's next: Further studies will likely refine historical climate data to provide more accurate benchmarks, helping to inform and adjust international climate policies and goals

💬 One quote: "It is possible that the world was cooler than the measurements reflect in Victorian times," scientists suggest, indicating a potential underestimation of past temperatures

📈 One stat: New data suggest the temperature between 1850 and 1900 was 0.24C lower than previously estimated, making last summer's rise 2.31C in the northern hemisphere
