The report The State of the Global Climate 2024 by the World Meteorological Organisation (WMO) reinforces the warnings we have already heard from Copernicus and other sources about how close we are to reaching the 1.5 degrees Celsius limit. According to this report, the global temperature is between 1.34 and 1.41 degrees higher than in the period from 1850 to 1900 due to the emission of greenhouse gases, the reduction of aerosols and other factors.
In any case, we are very close to the 1.5-degree threshold, which already represents a significant increase and entails serious consequences such as an increase in extreme weather events, melting ice and irreversible sea level rise. This report serves, once again, as an urgent call to action.
