World Meteorological Organization: Earth's energy imbalance reaches a new high.

March 23rd is World Meteorological Day. The "Global Climate Situation Report 2025" released by the World Meteorological Organization on that day pointed out that the degree of energy imbalance on Earth has reached the highest level since observations began in 1960. Energy imbalance on Earth refers to the difference between the energy entering the Earth system from solar radiation and the energy leaving the Earth's atmosphere. If the energy entering the Earth system is greater than the energy leaving the Earth's atmosphere, it means that a large amount of heat is accumulating in the Earth system. The "Global Climate Situation Report 2025" for the first time lists energy imbalance on Earth as one of the key climate indicators. The report states that of the excess energy retained on Earth, only 1% is stored in the atmosphere, leading to atmospheric warming. Approximately 5% of the excess energy is stored in the continental land. Over 91% of the excess heat is stored in the oceans. In 2025, the heat content of the oceans reached a historic high, with warming rates doubling from 1960 to 2005. Over the past two decades, the oceans have absorbed about 18 times the amount of energy consumed by humans each year. The warming of ocean temperatures has brought a series of negative consequences and chain reactions to the marine ecosystem, global weather systems, and other factors.
