| Description | Climate scenarios are essential scientific tools that help governments, businesses and society understand how today's policy choices may shape the future climate. By combining observations, emissions data and socio-economic projections, scientists can estimate how global temperatures and climate impacts may evolve under different development pathways.
Recent updates to these scenarios indicate that the previously considered "worst-case" emissions pathway is no longer regarded as plausible. While this reflects the positive impact of global climate action, scientists stress that the remaining scenarios still point to substantial warming and significant climate risks if emissions are not reduced more rapidly.
