Climate change is speeding up — the pace nearly doubled in ten years

The rate of global warming has accelerated significantly over the past decade, according to a comprehensive new analysis of global temperature data. The findings suggest that the Earth is now warming at a rate of approximately 0.35 °C per decade, nearly double the rate observed in the late 20th century.

Behind the Acceleration

Researchers attribute this acceleration to a combination of factors, including the continued rise in greenhouse gas emissions and a reduction in cooling aerosols. The phasing out of certain industrial pollutants, while beneficial for air quality, has inadvertently removed a "sunshade" effect that was masking some of the warming.

Ocean Heat Content

The study also highlights a dramatic increase in ocean heat content. The oceans absorb over 90% of the excess heat trapped by greenhouse gases, and recent measurements show that they are warming faster than previously thought.

"The oceans are the true memory of the climate system," explains Dr. James Hansen, a contributing author. "The rapid warming we are seeing there is a clear indicator that the Earth's energy imbalance is growing."

Urgent Action Required

The accelerated warming rate underscores the urgent need for aggressive climate action. The authors warn that without immediate and deep cuts in emissions, the world will likely surpass the 1.5 °C warming threshold much sooner than anticipated.
