The data published by Imperial College London on deaths caused by the May and June heatwaves is a stark reminder of how climate change is not only measured in degrees of temperatures but also in terms of lost lives (May and June heatwaves killed about 2,700 people in England and Wales, data suggests, 13 July).
While each death due to extreme heat is a preventable tragedy, mortality only represents the tip of the iceberg of how heat is impacting our health. Extreme heat also affects our mental health. Throughout the past weeks in the northern hemisphere, we have all experienced how it is making it harder for us to sleep, making us more irritable and reducing our ability to concentrate.
