aerosols

Why were 2023–2024 so unexpectedly hot, and is warming accelerating?

The record 2023–24 global temperature spike was driven primarily by a reduction in planetary albedo (fewer low clouds and less aerosol pollution), indicating that the rate of global warming has accelerated beyond the ~0.18°C/decade trend.
