Summary

Story summary

The NASA study reports Earth is darkening, with hemispheric differences, drawing on 24 years of satellite data.
In the Northern Hemisphere, absorbed solar radiation and longwave emissions rise, widening the radiation budget due to albedo, aerosols, and water vapor.
Arctic sea-ice decline and pollution controls alter cloud formation; models must account for hemispheric differences.
