Global Warming

Dramatic increase in average temperatures

An increase of 2°C compared to the average temperature in pre-industrial times is considered the threshold for catastrophic changes. For this reason, the international community has recognized that global warming must be kept below 2°C. The global average temperature today is 0.85°C higher than at the end of the 19th century. Each of the last three decades has been warmer than any previous decade since records began in 1850. According to the world's leading climate scientists, human activity has almost certainly been the main cause of global warming since the mid-20th century (ec.europa.eu ; 2020)..
