Climate scientists have observed an unprecedented streak of ocean heat lasting for over a year, with surface temperatures in various regions surpassing historical averages by 1 to 3 degrees Celsius.

Last year, global air temperatures soared to historic levels, possibly the hottest in over 100,000 years. Predictions indicate that 2024 could be even hotter.

The World Meteorological Organization warns of alarming ocean warming, impacting marine ecosystems and weather patterns.

Marine heatwaves engulfed over 90% of the oceans in 2023, leading to coral reefs fatal bleaching.

In areas like the Gulf of Maine, fish populations are already struggling to adapt to rapidly warming waters, impacting their growth and survival.

Scientists attribute ocean warming to factors like reduced pollution and volcanic eruptions. But the exact drivers of the extreme ocean warming remain unclear.

While there’s hope that a shift from El Nino to La Nina conditions could moderate temperatures, continued record warmth would signify uncharted territory for Earth’s climate future.
