Oceans hit unprecedented warmth as concerns mount among scientists

Scientists grapple with a surge in ocean heat, signaling a possible long-term planetary shift.

Scott Dance reports for The Washington Post.

In short:

• This past year marked a staggering increase in ocean temperatures, an event beyond previous records.
• Experts are investigating various causes, including climate patterns like El Niño and reduced pollution from shipping, but no single factor has been pinpointed.
• The warmth has persisted, affecting nearly the entire surface of the oceans and potentially indicating a significant shift in Earth's systems.

Key quote:

“The time scale of the oceans is not as fast as the atmosphere. Once a change is established, I would say it’s almost irreversible in time scales that go from centennial to millennial.”

— Celeste Saulo, secretary general of the World Meteorological Organization

Why this matters:

The continued record warmth of our oceans is not just an environmental anomaly; it's a profound change that could alter weather patterns, impact marine life, and influence human health globally.

Ocean heat waves are happening far more frequently than previously thought.
