In its third factsheet, Catavento highlights the key messages of the latest report by the Intergovernmental Panel on Climate Change’s (IPCC), released in August 2021. The study focuses on the scientifically confirmed consequences of the increase in greenhouse gases emissions and its results may influence decisions to be taken at COP 26, in November 2021 (Glasgow / United Kingdom).
The most relevant facts are listed below:
1 – The planet has already warmed by around 1.1°C compared to pre-industrial levels, with visible consequences in practically every region of the world;
2 – There is a scientific consensus that the human influence on global warming is unequivocal;
3 – Regardless of the projected scenarios for emission trajectories, the planet will reach the 1.5°C milestone of temperature increase by 2040;
4 – Negative emissions, driven by carbon removals from the atmosphere, will be essential to limit warming to 2°C increase by 2100;
5 – Considering a 67% likelihood of limiting global warming to 1.5 °C, the remaining global carbon budget is of approximately 400 GtCO2, or 10 years of current CO2 emissions;
6. Despite the worrying signs, there is still time to contain the potentially catastrophic consequences of the increasing frequency and intensity of extreme weather events, and the 2020-2030 decade is now commonly called the “Decade for Climate Action”. Thus, greater robustness and urgency are expected for the plans, targets and strategies to be defined at COP 26 by governments and private actors.
