UN climate report is ‘code red’ for humanity

The UN's Intergovernmental Panel on Climate Change report highlights five scenarios based on carbon emission reductions, predicting temperature increases between 2.1 and 4.6 degrees Celsius by the century's end. Despite progress, even optimistic scenarios fail to meet the Paris Agreement targets, leading to severe weather events and irreversible damage. Human activity is the primary cause, but limiting emissions can mitigate warming.
