Warming caused by human activities has increased temperatures by more than 0.2°C between 2013 and 2022, with greenhouse gas emissions at an unprecedented level, says an international study published this Thursday.
“Over 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 aim of the study is to provide up-to-date indicators from the IPCC 2021 report and to provide open data updated each year, to feed COP negotiations and political debate, as the current decade looms decisive in saving the Paris 2015 target.
“It is a harsh reality that shows the urgency of reducing global CO2 and methane emissions to help limit global warming and the consequent increased risk,” French paleoclimatologist Valérie Masson-Delmotte, who participated in the study, told reporters.
Representatives of all the countries are in Bonn to prepare for COP28, the major 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 that is now released comes in the middle of a decisive year for climate policy, with the publication of the first “global evaluation” of the commitments of the different States in the implementation of the Paris agreement, which aims to limit global warming. below 2°C, predicted for September and, if possible, 1.5°C compared to the pre-industrial period.
However, the warming caused by human activities, mainly 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.
