Learn English: Record Heat: More Sunlight, Less Clouds (normal)

2023 was the hottest year on record due to the Earth absorbing unusually high levels of solar radiation.

This increase is mainly attributed to a decrease in low-level cloud cover, especially over oceans.

While El Niño contributed, this additional absorbed sunlight explains the unexpected temperature surge.

Scientists worry this could indicate a feedback loop, intensifying future warming beyond current projections.
