Oops, We Did It Again: 2025 Second Hottest Year On Record

The past 11 years are now the warmest 11 years in the 176-year history of temperature records. What is especially concerning about 2025 is that it occurred during La Niña, a natural Pacific cooling pattern that usually brings lower temperatures. This time, it did not help. Climate scientist James Hansen reports that global warming is now speeding up by 0.31°C per decade, and he predicts we will pass the +1.7°C mark by 2027.

Emerging climate impact on carbon sinks in a consolidated carbon budget

Fossil CO2 emissions keep rising, pushing CO2 to 423 ppm and 1.36°C warming, risking a near-term breach of 1.5°C and exposing carbon accounting gaps.
