Earth’s Energy Imbalance Accelerates climate Change Concerns
Updated June 5, 2025
The rate at which Earth retains energy compared to the energy it releases into space is increasing unexpectedly, raising concerns among scientists. This growing earth energy imbalance is a critical indicator of climate change, but the capacity to monitor it is under threat.
NASA satellites, which provide high-resolution data on this imbalance, are approaching the end of their lifecycles. Researchers fear that the planned replacement may not be adequate. The next best measurement method lags by approximately a decade, making satellite data crucial.

Thorsten Mauritsen,a professor at Stockholm University and lead author of a commentary on the issue,emphasized the importance of continuous satellite monitoring. “What we get from these satellites is roughly one decade faster data, so that’s why it’s so critical,” Mauritsen said. “The absolute best option is that NASA continues.”
The growing energy imbalance means climate change is happening faster, Mauritsen explained. More energy accumulation leads to quicker temperature rises. It also highlights how much the climate system has already been affected and what is needed to restore balance.
Mauritsen noted that temperatures are expected to stabilize after fossil fuel use ceases. However, a persistently high imbalance pushes the stabilization temperature higher, reducing the amount of remaining CO2 emissions permissible to stay below a 2 degrees Celsius warming threshold.
While 2024 satellite data indicates a return to levels predicted by climate models, the future remains uncertain. Mauritsen said continued monitoring is essential to understand the trajectory of the earth energy imbalance.
Scientists Need Satellites
Measuring Earth’s energy imbalance requires specialized satellites. NASA’s CERES mission, comprised of four operational satellites, is slated for replacement in 2027 by the Free Mission.

The Free Mission consists of only one satellite. scientists are concerned that instrument failures could lead to data gaps.Continuous, overlapping readings from multiple satellites are essential for accurately tracking the evolution of Earth’s energy imbalance.
Furthermore, NASA lacks a formal plan to continue monitoring the imbalance after the Free Mission concludes. Instruments aboard the International Space station have limited operational lifespans.
Ocean temperature data can provide some insight into Earth’s energy imbalance, but these records have a 10-year delay and offer less spatial detail, Mauritsen said.
mauritsen also mentioned a NASA concept to use spherical satellites with accelerometers to measure radiation from all angles to calculate the energy imbalance. Though, budget cuts could hinder such advancements.
Mauritsen and other researchers are advocating for enhanced monitoring capabilities and further research into the evolution of earth’s energy imbalance.
“It tells us how far we are from stabilizing Earth’s climate, and that’s why we need to measure it,” mauritsen said. “If we don’t know this, then we are driving our climate system blindfolded.”
What’s next
Continued monitoring of Earth’s energy imbalance is crucial for understanding and addressing climate change. The future of NASA’s monitoring programs will play a vital role in these efforts.
