Something Is Wrong with Earth, Scientists Growing More Worried

Global temperature records have been repeatedly broken in recent years. Heatwaves are arriving more frequently, ice is melting faster, and extreme weather is becoming increasingly difficult to predict. However, what now worries scientists most is not merely the rise in temperature. New findings indicate that the Earth is absorbing far more energy than it is releasing back into space. More startlingly, the rate of this change is now exceeding the projections of many climate models that have long served as the world’s reference. Satellite data shows the Earth is absorbing far more energy than it releases back into space. This imbalance has been widening over the last two decades and has more than doubled since 2000. The findings are causing scientists to question whether climate change is developing faster than previously estimated. To understand the Earth’s Energy Imbalance (EEI), imagine the planet like a financial account. Every day, the sun sends energy to Earth. Some is reflected back into space, while the rest is absorbed by land, oceans, and the atmosphere. Meanwhile, the Earth continuously releases energy in the form of infrared radiation. As long as energy intake and expenditure are relatively balanced, global temperatures do not change much. The problem is that this balance is now shifting. Incoming energy continues to increase, but outgoing energy is not rising at the same pace. This difference is called the Earth’s Energy Imbalance, or EEI. In other words, the Earth’s system is now continuously ‘saving’ heat. According to scientists, as long as the EEI remains positive, global warming will continue even if surface temperature changes do not occur immediately. EEI is not just a new figure in climate science. For researchers, this indicator describes the ‘main engine’ driving global warming. As long as the Earth receives more energy than it releases, the climate system will continue to heat up. The impacts will not simply stop even if emissions eventually slow down. More than 90% of this excess energy does not directly heat the air but is absorbed by the oceans. The oceans then act as a massive heat reservoir that can influence global temperatures, weather patterns, and increase the likelihood of future heatwaves and extreme weather. Therefore, scientists consider EEI to provide a more fundamental picture than merely observing surface temperature changes. This change is monitored through NASA’s Clouds and the Earth’s Radiant Energy System (CERES) project, which has been measuring the Earth’s energy budget via satellites since the late 1990s. The instruments simultaneously record three main components: incoming solar energy, the amount of sunlight reflected back into space (albedo), and the infrared heat emitted by the Earth. Observations show that the Earth’s albedo is steadily declining. This means less sunlight is being reflected and more energy is being absorbed by the planet. At the same time, the Earth is releasing more heat into space, but the increase in outgoing energy is not keeping pace with the rise in incoming energy. As a result, the Earth’s Energy Imbalance continues to grow. The CERES findings are reinforced by the Argo float network, which measures ocean temperatures down to a depth of about six kilometres. Since over 90% of the Earth’s excess energy is stored in the oceans, the Argo data provides independent proof that this additional heat is indeed accumulating in the seas. The rise in EEI itself is not surprising; global warming was expected to increase the energy imbalance. The problem is the speed. The latest data shows the rate of increase is far greater than what many climate models, including those used by the Intergovernmental Panel on Climate Change (IPCC), had projected. ‘For the first time, we are really interpreting measurements, not just models,’ said Bjorn Stevens, Director of the Max Planck Institute for Meteorology in Hamburg, to The Economist. He described the findings as a game changer because scientists now have sufficient long-term observations to compare the real world with model simulations. More than 50 climate researchers expressed similar concerns in a scientific paper published in late 2025. They stated that the current EEI trend is ‘difficult to reconcile with climate models’, indicating that real-world conditions have moved beyond the range of variation previously estimated by the models. For scientists, the issue is no longer just whether the Earth is warming. The question now is whether the rate of change has already outpaced the ability of climate models to predict it. There is no single definitive answer yet as to why the Earth’s energy imbalance is increasing so rapidly, but most research points to two main causes. The first is that the Earth is reflecting less sunlight than before. The second involves changes in cloud cover that cause more energy to be trapped within the climate system. Both are linked to albedo, the Earth’s ability to reflect solar radiation back into space. When albedo decreases, more energy is absorbed than reflected.
