Scientists warn Earth could hit the 1.5°C climate limit sooner than expected
A new study published in Geophysical Research Letters indicates that global warming has accelerated significantly over the past decade. Researchers reached this conclusion by filtering out natural climate fluctuations like El Niño and volcanic activity from five major temperature datasets.
Why it matters
The acceleration of warming suggests that critical climate thresholds, such as the 1.5°C limit, may be reached sooner than previously projected, necessitating urgent policy adjustments.
For decades, the rise in Earth's average temperature has appeared to follow a fairly consistent upward path. Individual years have stood out because of events such as strong El Niño episodes or volcanic eruptions, but the broader trend seemed relatively stable. That picture is beginning to change.According to the study published in Geophysical Research Letters, titled “Global Warming Has Accelerated Significantly”, the pace of global warming itself has increased, with the past decade warming faster than any comparable period in modern records. Rather than relying on unusually hot individual years, the researchers removed the influence of short-term natural climate fluctuations before examining long-term temperature data.
