Reacción a "Extreme heat and air pollution expose nearly 40 per cent of the world’s population to dangerous levels of tropospheric ozone"

The report presents a new analysis of atmospheric data called Atmosphere Watch, focusing on the current year. Its significance lies in its global scope and its predictive capabilities. Specifically, the report highlights three areas with a potential impact on public health: ozone concentrations, smoke from fires and particulate matter concentrations.

Although the report highlights the cross-border nature of pollution, this is already a well-known fact. Therefore, it does not address new problems, but rather presents a powerful tool that will enable a better understanding of pollution situations. The key element is the significant amount of information the system processes. The report presents findings from around the world, illustrating both continental distribution and the contrasts between different regions. One notable point is that the emissions reduction strategy in Europe or North America has not been effective in reducing ozone levels, perhaps due to adverse weather conditions or forest fires.

Overall, the report’s findings could be considered preliminary, as they appear to be aimed, rather, at highlighting the potential applications of the information processed. Therefore, the data and products, which are publicly available, can be very useful to air quality managers, who will be able to take measures better suited to specific pollution situations. Furthermore, all these resources provide a solid foundation for scientists to analyse this information in greater detail and understand the atmospheric processes at the locations and times of interest.
