A new study published in Geophysical Research Letters provides evidence that global warming is accelerating, with the Earth warming faster over the last decade than any previous one on record. By statistically removing natural factors like volcanic eruptions and solar activity, researchers found a significant jump in the warming rate, beginning around 2015. This accelerated pace suggests that the Earth will breach the 1.5 degrees Celsius warming limit by 2030, much sooner than previously anticipated. While greenhouse gas emissions remain the primary cause, a contributing factor is the disappearance of the "cooling mask" provided by aerosols, as air pollution has decreased.
- Global warming is accelerating, with the Earth warming faster in the last decade than ever before.
- Statistical analysis removed natural climate variability to reveal a significant jump in the warming rate around 2015.
