Scientists assess the impacts of a warming ocean
With global average sea surface temperatures at record highs, ocean scientists associated with the WMO co-sponsored World Climate Research Programme have made a collective assessment of recent global trends and what may be expected in the future. This includes an observed basin-wide warming of the ocean and an increase in marine heatwaves.

Marine heatwaves occur when ocean temperatures in a given region are well above average for an extended period of time. Warmer ocean temperatures impact the marine environment and associated ecosystems, and ocean heat can also fuel developing tropical cyclones.

What’s behind the widespread extent of recent marine heatwaves?

Global monthly-mean ocean temperatures are currently at an all-time high relative to temperatures since the start of the instrumental record and potentially extending even further into the past, with 27% of the global ocean experiencing a marine heatwave as of August 15, 20231. The World Meteorological Organization recently announced that El Niño conditions have developed for the first time in seven years. Tropical Pacific surface temperatures are warmer during El Niño years as upper ocean heat content is redistributed from west to east across the Pacific, explaining the intense warming developing in the eastern equatorial Pacific. Besides the tropical Pacific, a recent study has shown that the most widespread marine heatwaves have occurred during major El Niño events. A region particularly affected by El Niño is the Northeast Pacific, which is also currently undergoing extremely warm conditions.

Other compelling reasons could explain recent warming in other regions. For example, the North Atlantic has experienced a sequence of marine heatwaves extending from the tropics to mid-latitudes. This warming pattern is consistent with the negative phase of the North Atlantic Oscillation, a natural pattern of atmospheric variability that can impact surface winds and influence ocean temperatures. The North Atlantic Oscillation was strongly negative from mid-April to mid-May 2023 and most of July, consistent with the observed Atlantic warming pattern. During this negative phase, less Saharan dust is blown over the tropical Atlantic Ocean, allowing more sunlight to reach the surface and warm the ocean. It is possible that there are additional local drivers of ocean warming. However, more data and research are needed to definitively identify the specific mechanisms of current marine heatwaves in different regions.

In addition to mechanisms related to natural variability of the climate system, we know that about 90% of the excess heat associated with global warming has been absorbed by the ocean, causing the global ocean surface temperature to increase by about 0.9°C since pre-industrial times. This long-term warming manifests as an intensification and persistence of ocean temperature extremes, by exacerbating the impact of internal climate variations like El Niño and the North Atlantic Oscillation. Therefore, it is very likely that climate change has contributed to the intensity and widespread coverage of current marine heatwaves.

How long will these m[...]
