Global Warming Statistics

The planet is warming fast enough to reshuffle what drought and heat look like, with 2011 to 2020 running about 1.09°C warmer than 1850 to 1900 and NOAA placing 2023 at the top of the warmest-years record. From CO2 at 421 ppm at Mauna Loa to rising sea levels and ice loss, the page connects real measurements to the hard financing gap for adaptation and mitigation, showing what it means for 1.5°C and 2.0°C risk.

Global temperatures have not just drifted upward. NOAA’s global land and ocean temperature record shows 2016, 2020, 2023, and 2024 among the warmest years, and 2023 is the warmest on record. At the same time, greenhouse gas measurements and rising disaster costs are adding up to a clear mismatch between what the climate system is experiencing and what adaptation and emissions plans are prepared for.

Risk & Impacts Interpretation

From rising sea levels of about 21 cm since 1880 to Arctic sea ice declining about 13% per decade and Greenland losing roughly 279 billion tons of ice each year, the data shows escalating physical impacts as warming targets like 1.5°C and 2.0°C approach, underscoring the Risk and Impacts category that higher temperatures are translating into faster and broader climate change effects.

Climate Change Metrics
