From 2020 to 2100 is 8 decades. Increase = 8 × 0.4 = 3.2°C. Temperature in 2100 = 14.8 + 3.2 = 18.0°C.

The Future of Global Temperatures: Projecting Climate Change from 2020 to 2100 From 2020 to 2100 spans eight decades—a critical window in humanity’s fight against climate change. Scientists project that global temperatures could rise by approximately 3.2°C over this period, driven predominantly by ongoing greenhouse gas emissions and feedback climate processes. By 2100, global average temperatures are expected to reach 18.0°C, marking a significant shift from today’s climate baseline. --- ### Why This 3.2°C Increase Matters
