We are +1°C above the baseline temperature
On a climate scale our position depends on the mean temperature on earth. This temperature depends on natural cycle (such as the glacial cycle) and human activities : by adding carbon dioxyde in the atmosphere, we amplify the greenhouse effect and warm up the earth "artificially". In 2020 we burned enough petrol, gaz and coal to increase the earth temperature by +1°C compared to its baseline temperature*.
Such warming may seem non-significant but at +1°C we already feel an increase in the frequency and intensity of natural disasters (forests fire, floods, droughts, etc ...) and we know that food security and access to water are seriously threatened in certain regions**. Scientists warn us that damage will be irreversible from +1.5°C . They also say that beyhond +2°C (limit set during the Paris agreements by the politics), we may be unable to adapt to the consequences of global warming***.
