A new analysis of NASA's climate data shows that the rate of global warming has accelerated dramatically in recent years, with the fastest warming trend on record occurring in the last 30 years. Researchers warn that this rapid acceleration is not just a temporary blip, but a concerning new reality that could lead to more severe climate impacts if the underlying causes are not addressed.

Why it matters

The alarming acceleration of climate change revealed by this data underscores the urgent need for global action to reduce greenhouse gas emissions and mitigate the growing risks posed by extreme weather, rising seas, and other consequences of a rapidly warming planet. Understanding the factors driving this acceleration, such as changes in cloud cover and aerosol pollution, is crucial for developing effective strategies to combat climate change.

The details

The analysis, conducted by The Washington Post using NASA's GISS Surface Temperature Analysis, shows that from 1970 to 2025, the rate of global warming has skyrocketed from -0.03°C to 0.25°C per decade. This represents a 42% increase in the warming rate over the past decade compared to the previous 40 years. Researchers point to a decrease in low-lying cloud cover as a potential contributor to the record-breaking heat, in addition to reduced aerosol pollution. However, the exact mechanisms behind the acceleration are still being studied, with some scientists warning that a strengthening cloud feedback loop could cause the rapid warming to persist.

  • From 1970 to 2025, the rate of global warming increased from -0.03°C to 0.25°C per decade.
  • The last 11 years have been the warmest on record globally.

The players

Robert Rohde

Chief scientist at Berkeley Earth, who emphasizes that "We're not on the same path as before. Something has undeniably changed."

Zeke Hausfather

A climate scientist at Stripe, who confirms that "There's growing acceptance that we're witnessing a detectable acceleration of warming."

Chris Smith

A researcher at the University of Leeds and the International Institute for Applied Systems Analysis, who explains that "Every climate model agrees on the cooling effect [of clouds], but the size of that effect is still up for debate."
