The global average temperature has risen by 1.1°C since pre-industrial times, primarily driven by human greenhouse gas emissions. Recent climate projections suggest this warming trend could accelerate significantly by 2050, potentially reaching 2.4°C above baseline.
Atmospheric carbon dioxide concentrations have now reached levels not observed in approximately 800,000 years of ice core records. The scientific consensus overwhelmingly supports immediate and substantial policy interventions to prevent the most severe climate outcomes.
The 2015 Paris Agreement established internationally binding targets to limit global warming to 1.5°C above pre-industrial levels. However, current national commitments fall considerably short of what is required to meet these targets.
