"Radiative imbalance" refers to a situation where Earth's energy system, particularly the balance between incoming solar radiation and outgoing heat radiation, is disrupted. It means that more energy is being absorbed by the Earth than what is being emitted back into space, leading to a build-up of excess heat in the atmosphere and oceans. This imbalance is a key factor in climate change and can cause various impacts such as rising temperatures, melting ice, and extreme weather events.
