June 26, 2025 - Increasing ocean heat content is contributing to sea level rise, ocean heat waves and coral bleaching, and melting of ocean-terminating glaciers and ice sheets around Greenland and Antarctica.

August 11, 2023 - Between 1950 and 2020, the global ... It induces the expansion of the ocean, alters its stratification and currents, diminishes oxygen availability, elevates sea levels, and intensifies hurricanes and storms....

This has caused ocean temperatures to rise slowly, but even small differences can cause significant and dangerous shifts in ocean health and stability. Rising amounts of atmospheric greenhouse gasses have caused many physical changes to our oceans.

April 7, 2025 - If all the glaciers and ice sheets melted, sea levels would rise by a significant 60 metres (195 feet), causing flooding, coastal erosion, land loss, and more. An Amazon river dolphin breaching out of the water in Rio Negro tributary.

Warmer sea surface temperatures influence weather patterns and shift precipitation, causing some regions to experience intense rainstorms and flooding and exacerbating drought conditions and wildfire risks in others.

“But every fraction of a degree ... biome or ice sheet collapse in Greenland or the Antarctic.” · Warmer oceans can change climate cycles, influence storms and melt the polar ice caps....

A mind-bending amount of energy is trapped in Earth's oceans. Here’s what that means for the planet.

In addition, rising sea levels can damage infrastructure and make coastal communities more vulnerable to storm surges and flooding. Warmer ocean water also provides more energy for storms to develop and intensify.

As the excessive heat and energy warms the ocean, the change in temperature leads to unparalleled cascading effects, including ice-melting, sea-level rise, marine heatwaves, and ocean acidification.

July 2, 2024 - As a result, the greenhouse effect increases and global warming trends rise – altering the chemistry and heat content of the ocean. SDG14 covers the main focuses of the ocean emergency, including coastal eutrophication, ocean acidification, ocean warming and sea level rise, plastic pollution, and overfishing. These five major impacts on our oceans, fuelled by climate change, have resulted in broken temperature records nearly every single day over the past year, with massive die-offs due to intense storms, bleaching events, and dead zones (due to oxygen depletion).

“We know severe temperature rises can lead to mass mortalities of sea life, increase ocean acidification and disrupt the currents that influence our weather patterns, potentially causing hundreds of millions of dollars in economic losses and ...

January 30, 2024 - Higher-than-normal sea temperatures have widespread effects across the ocean. They cause sea level rise as the water experiences thermal expansion.

May 9, 2024 - The world's oceans may be warming faster than expected and the impacts will be felt from polar ice shelves to many of the world's coastal cities.

Climate change, driven by increased ... impact is the rise in ocean temperatures, which leads to coral bleaching and increases the susceptibility of corals to diseases....

July 5, 2024 - One dramatic consequence of this warming is an increase in sea levels across the globe. The ocean absorbs 90% of the excess heat released into the atmosphere, and as water heats up it expands. Warming ocean temperatures now account for 40% of the global rise in sea levels, and the rate of rising has doubled over the past 30 years totalling 9cm.

July 20, 2022 - The ocean absorbs most of the excess ... affect marine species and ecosystems, causing coral bleaching and the loss of breeding grounds for marine fishes and mammals....

1 month ago - The researchers point out that these underwater heatwaves can cause increases of up to 5 degrees C above seasonal average temperatures over the course of just days and can last for several weeks. This rise in temperature can lead to rapid physiological changes in these reef fishes, which could have long-term effects on survival.
