Scientists found out that anthropogenic warming of the Earth has reached record rates
According to the analysis, in 2023, the contribution of people to the increase in global temperatures amounted to 1.3 °C, while the total amount of warming for the year reached 1.43 °C. It was influenced by the climatic phenomenon of El Nino and other natural factors.
According to the researchers, anthropogenic warming is increasing at an unprecedented rate for instrumental data, reaching about 0.26°C per decade in 2014-2023. Such high rates are caused by a combination of consistently high greenhouse gas emissions, equivalent to 53 billion tons of CO2 per year, as well as continued improvement in air quality, which reduces the force of anthropogenic cooling by atmospheric aerosols. According to the report, the remaining carbon balance (the amount of carbon dioxide that can be released before the world faces global warming 1.5°C above pre-industrial levels) is only about 200 billion tons, which corresponds to current emissions in about five years, gazeta.ru reports.
