Warming caused by human activities has increased the temperature by more than 0,2°C between 2013 and 2022, with greenhouse gas emissions at an unprecedented level, says an international study published today.
“In the period 2013-2022, human-caused warming increased to an unprecedented level of more than 0,2°C per decade,” reads an article published in the scientific journal Earth System Science Data.
The article is signed by around 50 researchers and is based on the methods of the Intergovernmental Panel on Climate Change (IPCC), linked to the UN.
The purpose of the study is to provide updated indicators of the 2021 IPCC report and provide open data updated every year, to feed the COP negotiations and the political debate, as the current decade is seen as decisive to save the goal of the Paris 2015.
“It is a harsh reality that shows the urgency of reducing global CO2 and methane emissions to help limit global warming and the consequent increase in risk,” French paleoclimatologist Valérie Masson-Delmotte, who participated in the study, told reporters.
Representatives of all countries are in Bonn to prepare for COP28, the great UN climate conference scheduled for the end of the year in Dubai.
Among other topics, the discussion on the use of fossil fuels should mark the conference.
The data released today comes in the middle of a decisive year for climate policy, with the publication of the first “global assessment” of the commitments of the various States in the implementation of the Paris agreement, which aims to limit warming below 2°C, scheduled for September. and, if possible, 1,5°C compared to the pre-industrial period.
However, the warming caused by human activities, essentially with the use of fossil fuels (coal, oil, gas), has already reached 1,14°C in the period 2013-2022 and 1,26°C in 2022, according to the study calculations.
Scientists warn that humanity is facing a “critical” decade and that the 1,5°C limit could be reached or exceeded in the next 10 years.
