The dominant cause of climate change is the accumulation of greenhouse gases from burning fossil fuels, with global CO2 concentrations reaching 419 ppm in 2023 and fossil fuel emissions projected to rise by 1.1% in 2025.

CURRENT STATE

This accumulation is producing record-high global temperatures, with 2024 being the warmest year on record, global average temperatures surpassing 1.55°C above pre-industrial levels, and global greenhouse gas emissions reaching 60.63 Bt CO₂e in 2025. Arctic ice loss and increased methane emissions amplify warming.
