Divide over causes of faster warming.

The article focuses on the recent acceleration of global warming, highlighting scientific debate over whether this surge is primarily due to human-driven factors or natural climate variability. It discusses how reductions in sulphur aerosol pollution—particles that previously masked some warming—have unmasked hidden heat, contributing to faster temperature increases since the 2010s. Natural phenomena such as solar cycles, volcanic eruptions, and El Niño events have also influenced recent temperature spikes, complicating efforts to isolate human impact. Some researchers suggest emerging climate feedbacks, particularly involving low-lying clouds, may further accelerate warming beyond current model predictions. The article underscores the urgency of reducing fossil fuel emissions to mitigate potentially severe climate outcomes. [Extracted from the article]
