Earth Approaches Critical 1.5°C Warming Threshold for Second Straight Year

Global temperatures in April 2025 reached 1.49°C above pre-industrial levels, nearly matching 2024’s record, Earth.com reported citing data from Berkeley Earth. Scientists warn the planet is now on track to exceed the Paris Agreement’s 1.5°C threshold for an unprecedented second consecutive year, signaling a potential climate tipping point.

The warming trend shows no signs of slowing, with 21 of the past 22 months surpassing the critical benchmark. Regions like Iran experienced their hottest April on record, while Arctic sea ice coverage shrank 3% below average. Despite a recent La Niña event that typically brings cooling effects, temperatures remained stubbornly high. Climate models now indicate an 18% chance 2025 could become the hottest year in recorded history.

European Centre for Medium-Range Weather Forecasts experts emphasize these sustained highs demonstrate the urgent need for accelerated emissions reductions. The findings come as extreme weather patterns intensify worldwide, from flooding in Europe to unprecedented heatwaves across Asia. Scientists stress that without immediate global action, the 1.5°C target may soon become unattainable.
