Recent satellite data reveal that the Earth's Northern Hemisphere is absorbing more sunlight than the Southern Hemisphere, breaking the long-standing symmetry. This shift is attributed to melting snow and ice, reduced pollution, and increased water vapor, potentially impacting global climate patterns. The study highlights the complex interactions between clouds, aerosols, and surface changes in Earth's energy balance.

A recent study confirms that climate projections from the mid-1990s accurately predicted global sea-level rise over the past three decades, though they underestimated ice melt contributions. Satellite data has been crucial in tracking these changes, revealing that sea levels are rising faster than initially thought, with regional variability influenced by ice sheet dynamics. The findings underscore the importance of refining localized forecasts to better prepare vulnerable regions for future sea-level rise.
