The UN has warned that global warming could exceed 1.5ºC in the coming years. This alarming projection arises from a report by the UN Environment Programme that emphasizes the need for immediate emission cuts.
The United Nations (UN) has indicated that the rise in global temperature could surpass 1.5ºC in the coming years, according to a report from the UN Environment Programme (UNEP). This report, titled Limiting Overshoot, highlights that implementing a strategy of "overshoot, peak and decline" is essential to mitigate the effects of warming.
To achieve this, sustained cuts in greenhouse gas emissions, including methane, are necessary, as well as promoting long-term removal of carbon dioxide. Adaptation also plays a key role, as it can reduce vulnerability to the impacts of climate change.
The UN Secretary-General, Antonio Guterres, warned that extreme climate phenomena, such as fires and floods, are signs of what is to come. Guterres stated that it is crucial "that the temperature increase above 1.5 degrees is as small and brief as possible," which will require "unprecedented ambition."
The report also outlines temperature scenarios, with the most optimistic predicting a maximum increase of 1.8ºC above pre-industrial levels. However, most forecasts indicate higher peaks. The first months with temperatures above 1.5ºC were recorded in 2015 and 2016, and deviations have been observed again in 2023.
Exceeding 1.5ºC carries severe risks, such as destabilizing ice sheets and degrading the Amazon rainforest. At recent climate summits, countries reaffirmed their commitment to limit global warming.
