According to the Intergovernmental Panel on Climate Change (IPCC), the global average temperature has increased by approximately 0.85°C (1.5°F) from 1880 to 2023. This increase in temperature is largely due to human activities such as the burning of fossil fuels, deforestation, and agriculture, which have led to an increase in greenhouse gas emissions in the atmosphere.
The IPCC also notes that the rate of warming has accelerated in recent decades, with the most rapid warming occurring in the past few decades. This has led to a range of observed impacts, such as rising sea levels, more frequent and severe heatwaves, changes in precipitation patterns, and an increase in the frequency and intensity of extreme weather events.
It is important to note that while the global average temperature has increased by 0.85°C since 1880, there is variability in regional and local temperature trends, and some areas have experienced greater warming than others. Additionally, the IPCC warns that if greenhouse gas emissions continue to rise at the current rate, the global average temperature could increase by 1.5°C (2.7°F) or more by the end of this century, with potentially severe and irreversible impacts on the planet's ecosystems and human societies.
