Sharp increase in CO2 emissions: Impact on the climate

The issue of climate change has become one of the major concerns of our time. Debates about greenhouse gas emissions, record temperatures and extreme weather phenomena are omnipresent in the media and political discussions. At the heart of this climate crisis is carbon dioxide (CO2), the main greenhouse gas responsible for global warming. The year 2022 marked a worrying turning point, with an annual increase in the concentration of CO2 in the atmosphere that has tripled since the 1960s. This alarming trend raises essential questions about the causes, consequences and actions needed to mitigate the effects of climate change.
