Overview

  • April 2025 was 1.51°C above pre-industrial levels, making it the second-hottest April ever recorded, according to Copernicus Climate Change Service data.
  • The 12-month period from May 2024 to April 2025 averaged 1.58°C above pre-industrial levels, the highest annual figure on record.
  • Sea surface temperatures outside polar regions averaged 20.89°C in April 2025, the second-highest for the month in recorded history.
  • Scientists warn that global warming is accelerating, with projections suggesting the 1.5°C threshold could be consistently breached by mid-2029 or sooner.
  • Experts attribute the persistent heat to human-driven emissions, with current warming likely representing the Earth's highest temperatures in 125,000 years.
