Significant increase in frequency and seriousness The heatwave worldwide, during the period 2000-2023, records a new scientific study by ETH Zurich, published in Nature magazine. Extensive analysis directly links human activity and emissions pollutant One of the largest producers of fossil fuels and cement with the worsening of extreme thermal events that occurred in various parts of the globe.

The research team mapped 213 major heat episodes on all continents, but noted that “Africa and South America remain under -supplied due to incomplete data”. During the past decades, the climate change It appeared to increase the likelihood and intensity of these phenomena.

Company emissions and contribution to global warming

In the context of the study, scientists have analyzed the impact of emissions exclusively from the 180 largest fossil fuel and cement producers. According to the findings, this group is responsible for the 60% of total anthropogenic carbon dioxide emissions from 1850 until today. The remaining percentage is mainly attributed to land change activities.

It is noteworthy that, as noted, the broadcasts of these companies have contributed decisively to the climate crisis, intensifying the heat: “Fourteen of the 180 companies have an equivalent effect with the remaining 166 in total”. However, it is emphasized that even the smaller producers are enough to influence extreme weather conditions.

By the findings of the study

Evidence shows that global warming has led to an increase in the likelihood of fuel appearance 20 times During the period 2000-2009 compared to 1850-1900. In the 2010-2019 decade, this increase was fired at 200 times. Scientists emphasize that it is now clear that tackling broadcasting by large industries and adopting ambitious sustainability policies is a critical factor in stopping future extreme climate phenomena.
