Human contribution to the European heatwave of 2003

Stott, Peter A., Stone, D. A., Allen, M. R.·2004·Nature

Abstract

The summer of 2003 was probably the hottest in Europe since at latest ad 1500, and unusually large numbers of heat-related deaths were reported in France, Germany and Italy. It is an ill-posed question whether the 2003 heatwave was caused, in a simple deterministic sense, by a modification of the external influences on climate--for example, increasing concentrations of greenhouse gases in the atmosphere--because almost any such weather event might have occurred by chance in an unmodified climate. However, it is possible to estimate by how much human activities may have increased the risk of the occurrence of such a heatwave. Here we use this conceptual framework to estimate the contribution of human-induced increases in atmospheric concentrations of greenhouse gases and other pollutants to the risk of the occurrence of unusually high mean summer temperatures throughout a large region of continental Europe. Using a threshold for mean summer temperature that was exceeded in 2003, but in no other year since the start of the instrumental record in 1851, we estimate it is very likely (confidence level >90%) that human influence has at least doubled the risk of a heatwave exceeding this threshold magnitude.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Globally, the heat wave in Europe in 2003 caused 14,802 deaths in France alone and the heat waves in the future were estimated to occur at least twice as frequently as the 2003 European heat waves.

    “Globally, the heat wave in Europe in 2003 caused 14,802 deaths in France alone and the heat waves in the future were estimated to occur at least twice as frequently as the 2003 European heat waves [50].”
  • Because of climate change, extreme weather is more generally on the rise, making extreme weather events more frequent, intense, and complex.

    “we do know that because of climate change, extreme weather is more generally on the rise, making extreme weather events more frequent, intense, and complex.”
  • It cannot be said with certainty that any one specific extreme weather event is directly caused by climate change.

    “while we cannot say with certainty that any one specific extreme weather event is directly caused by climate change”
  • There is an increasingly strong body of literature highlighting causal linkages between climate change and extreme weather events.

    “There is now an increasingly strong body of literature which highlights the causal linkages between climate change and extreme weather events (see [45–50]).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
