In its annual climate report, the World Meteorological Organization (WMO) has warned that the Earth's climate is more out of balance than at any point in recorded history, primarily due to rising greenhouse gas levels. For the first time, the report includes the Earth's energy balance as a central climate indicator, which assesses the amount of solar energy hitting the planet compared to the energy released back into space. The findings reveal that in 2025, this energy balance became increasingly skewed, with greenhouse gases acting like a thick blanket that traps excess heat around the Earth, resulting in warmer oceans and more extreme weather patterns.

The report highlights that over 91% of the excess heat generated by climate change is stored in the world's oceans, which acts as a significant buffer preventing land temperatures from rising even more drastically. However, this buffering is becoming increasingly problematic as ocean temperatures are now rising at an unprecedented rate, reaching record heat content last year. The implications are dire, as emphasized by WMO Secretary-General Celeste Saulo, who notes that humanity will live with the consequences of these changes for hundreds and thousands of years to come.

The evolving climate crisis underscores the urgent need for global action to address greenhouse gas emissions and mitigate the impacts of climate change. With the Earth’s energy balance tipping further towards heat retention, the potential for catastrophic weather events and biodiversity loss increases, highlighting the critical importance of understanding and responding to these climate signals at both local and global levels.
