CBS News Aliza Chasan highlights the alarming increase in sea surface temperatures in the North Atlantic and the potential impacts of climate change.

With the return of El Niño, warmer temperatures are expected to persist and affect sea ice levels, fisheries, and coral. Experts are concerned about entering uncharted territory and anticipate more temperature records to be broken, extending into 2024.

The National Oceanic and Atmospheric Administration warns that by September, about half of the world's oceans may experience marine heat wave conditions, an unprecedented occurrence. The high ocean temperatures are causing coral bleaching, which makes coral vulnerable to diseases, and are affecting fisheries as marine life moves toward cooler waters. The warming ocean temperatures also lead to reduced oxygen levels, which can result in fish deaths.

Marine heat waves can create harmful algae hotspots, producing toxins that accumulate in shellfish and pose risks to human consumption. It is noted that around 90% of global warming is happening in the ocean, largely attributed to human-caused climate change.
