Earth’s Oceans on Fire: Record Heat in 2024
Earth experienced unprecedented heat last year, with Siberian heatwaves, West Coast wildfires, and hurricanes. The total heat in the upper oceans reached levels higher than any year since 1950.
Rising Ocean Temperatures
According to the Journal of Advances in Atmospheric Sciences, 2017–2019 were previously the hottest years, but 2024 surpassed them all. Data shows a global ocean temperature increase of 1.2°C since the 1950s, rising at 0.2°C per decade. If trends continue, this could exceed 1.5°C by 2030.
Heat Absorption in Oceans
Oceans absorbed 1,021 joules of additional heat compared to 2019, the highest thermal content recorded since 1955. This amount equals 61 times all electricity generated worldwide. The heat affects marine ecosystems, fueling typhoons, algal blooms, and even seal pup strandings.
Causes of Ocean Warming
Human activities are the primary driver. Carbon emissions from fossil fuels—coal, oil, and natural gas—are accelerating climate change. Changes in the atmosphere and ocean circulation exacerbate heat absorption, leading to intensified rainfall and ecosystem disturbances.
Urgent Actions Needed
The current state is alarming, and countries must act decisively. Some, like Pakistan, are planting trees to offset carbon emissions. Global cooperation and practical solutions are essential to protect future generations from catastrophic climate impacts.
