Global average temperatures have risen by 1.2°C since pre-industrial times. If models predict an additional increase of 0.3°C per decade, how much will temperatures rise by 2050, assuming current trends continue from 2025?

Global Average Temperatures: Projected Rise to 2050 Under Current Trends Global average temperatures have already risen by 1.2°C since the pre-industrial era, marking a profound shift accelerated by human activity and greenhouse gas emissions. According to climate models and current warming trends observed from 2025 onward, scientists project an additional temperature increase of 0.3°C per decade if current emission levels persist. ### Current Warming Trend and 2025–2050 Outlook As of 2025, global temperatures are rising at a pace that reflects accelerating climate change. With a warming rate of approximately 0.3°C per decade, modeling indicates that by 2050—just 25 years from now—global temperatures could increase by an additional 0.75°C. This projection is based on observed trends, ongoing emissions, and climate sensitivity estimates.
