A study of the correlation between temperature and mortality in the Indian city of Pune has found that cold, rather than heat, is by far the bigger killer.
Urgent need for policies addressing rising temperatures to mitigate the temperature-attributable mortality related to climate change
In this study we have studied the effects of rising temperatures on mortality in Europe according to three climate change scenarios. Depending on the scenario, total attributable mortality will increase notably due to the great increase of heat attributable mortality that will outweigh the reduction in cold attributable mortality. This increase in mortality attributable to temperatures will be more notorious in regions more exposed and vulnerable to heat.
Without Strong Mitigation Measures, Climate Change Will Increase Temperature-Attributable Mortality in Europe
If global warming is not curbed, the increase in heat-related deaths will outstrip the decline in cold-related mortality, especially in the Mediterranean Basin.
Improved Air Quality During First Wave of COVID-19 Prevented Around 150 Premature Deaths in Major Spanish Cities
The study evaluates the changes in NO2 and O3 levels along with the associated impact upon premature mortality during the lockdown of the first wave of COVID-19 across the main Spanish cities. The findings show a strong reduction in NO2 levels (-45% on average) that was associated with a significant decrease in the number of deaths (172). This reduction in mortality from the NO2 drop was however partially compensated by a small increase in the number of deaths (22) associated with the rise in O3 levels during the analysed period in the most populated Spanish cities.
The study assesses the eventual changes in the seasonal distribution of temperature-related mortality from respiratory diseases in Spain between 1980 and 2016.The findings show the complete reversal of the seasonality of temperature-attributable mortality, with a significant shift of the maximum monthly incidence from winter to summer, and the minimum monthly incidence from early and late summer to winter. The reversal in the seasonal distribution of the attributable deaths is not driven by the observed warming in both winter and summer temperatures, but rather by a larger adaptation to cold than heat.
The study analyses trends in temperature-related mortality from cardiovascular diseases in Spain between 1980 and 2016. The main findings show that deaths attributable to heat for the period 2002-2016 were more than 42% lower in men and more than 36% lower in women than in 1980-1994, while deaths attributable to cold were 30% lower in women and nearly 45% lower in men. The study concludes that the observed warming of the climate in Spain has occurred in parallel with substantial adaptation to both high and low temperatures.
The objective of the study was to ascertain whether the pattern of mortality in Europe was procyclical or countercyclical, that is, whether the downward trend in the death rate accelerates or slows down during periods of economic recession. We showed that the decline in mortality accelerated during the recession years, and the tendency towards a reduction in mortality was more marked in the countries and regions where the recession was most severe. The study also considered the daily temperatures recorded during the whole study period to determine whether the trends observed were affected by the seasons, revealing that the relationship between variations in GDP and mortality was accentuated during the coldest months of the year.
