Table 2. Changes in attributable number and fraction (95% eCI)* of temperature-related MI cases per decade in Augsburg assuming global warming of 1.5 °C, 2 °C, and 3 °C.
Global warming | Attributable number | Attributable fraction (%) | ||||
Heat | Cold | Net change | Heat | Cold | Net change | |
1.5 °C | 17 [−1; 46] | −24 [−87; 32] | −6 [−60; 50] | 0.2 [0; 0.5] | −0.2 [−0.9; 0.3] | −0.1 [−0.6; 0.5] |
2 °C | 54 [1; 124] | −36 [−101; 43] | 18 [−64; 117] | 0.6 [0; 1.3] | −0.4 [−1.0; 0.4] | 0.2 [−0.7; 1.2] |
3 °C | 109 [4; 313] | −46 [−142; 56] | 63 [−83; 257] | 1.1 [0; 3.2] | −0.5 [−1.5; 0.6] | 0.7 [−0.9; 2.7] |
*The 95% eCI (empirical confidence interval) was obtained by considering the uncertainty of concentration–response function using 5000 Monte Carlo simulations and four global climate models.
Explanation: Global warming of 2 °C, for example, is associated with 54 additional heat-related events and 36 fewer cold-related events, resulting in a net change of 18 additional temperature-related events per decade. Thus, 0.2% of all MI cases can be attributed to global warming.
