    "description": "After every record heatwave the same question returns: was this climate change? Isabel Gelfert shows how attribution science answers it rigorously. This short walks through simulating the world twice, once as it is and once as it might have been without emissions, and explains how comparing the two turns a philosophical question into a number a court or a ministry can use.",

The ratio of probabilities gives a concrete statement: this heatwave was made, say, five times more likely and two degrees hotter. These numbers now inform adaptation planning, loss-and-damage debates, and climate litigation."
