<h1>Climate mitigation urged as rising greenhouse gases and record temperatures intensify sea level rise, displacement and food insecurity risks.</h1> Atmospheric greenhouse gas concentrations and global warming intensified in 2023-2024, with carbon dioxide at a multi millennial high and recent years the warmest on record. Rising emissions and the 2023-24 El Nin o drove record temperatures, accelerated sea level rise, worsening glacier mass balance, and severe weather events that increased displacement, food insecurity and economic losses. The report stresses that limiting long term warming to 1.5 degrees Celsius remains possible if national policymakers adopt stronger mitigation measures, update national climate plans and accelerate deployment of clean renewables to reduce emissions and risks.
