Tackling Climate Change
In 2020, concentrations of global greenhouse gases reached new highs, and real-time data point to continued increases. As these concentrations rise, so does the Earth’s temperature. In 2021, the global mean temperature was about 1.1°C above the pre-industrial level (from 1850 to 1900). The years from 2015 to 2021 were the seven warmest on record.
To limit warming to 1.5° Celsius above pre-industrial levels, as set out in the Paris Agreement, global greenhouse gas emissions will need to peak before 2025. Then they must decline by 43 % by 2030 and to net zero by 2050. To address climate change, 195 countries commited to limit global temperature rise to well below 2 degrees Celsius and are articulating climate action plans to cut emissions and adapt to climate impacts through nationally determined contributions. However, current national commitments are not sufficient to meet the 1.5°C target.
