One of the most severe marine heatwaves on Earth has developed off the coast of Ireland and the UK, with water temperatures as high as 4-5°C above normal.
NOAA's Marine Heatwave Watch has categorized this event as a Category 4 (extreme) marine heatwave.
This continues the trend of a record hot North Atlantic as previous record high ocean temperature records continue to get shattered.
At a global level, no ocean basin is seeing such widespread and intense marine heatwaves as the North Atlantic.
Sea surface temperatures have skyrocketed to above normal levels across nearly every major European sea in the last month, especially in the Baltic Sea, North Sea and western Mediterranean Sea.

From being entrenched in a multi-year extreme drought to having one of the deepest snowpacks on planet Earth.
The latest drought monitor shows that this winter's storms have completely removed drought across the Central Coast, part of the Sierra Nevada, and the far North Coast.
Over the following weeks, drought removal is likely across SoCal, the Bay Area, and all of the Sierra Nevada.
This before and after of the drought monitor from October to present day shows the dramatic improvement in drought across California this winter.
Taking into account the intensity, duration, and extent of the ongoing heatwave, as well as the exceptionally warm overnight lows and the added humidity (especially in SoCal), we are looking at one of the worst heatwaves in modern history for California.
Last night SoCal experienced a brutally hot night with millions not seeing temperatures dip below 80F, and that's combined with brutal humidity.
San Diego only got down to 82F, making it one of the hottest nights in city history. The average daytime high in September is 77F.
Up north, much of interior Central and Northern California could see some of their hottest days ever this week.
Places like Sacramento could see 5 straight days of 110+ and potentially record their hottest day ever. This is deadly heat for the entire population.
China is experiencing the worst heatwave ever recorded in global history.
The combined intensity, duration, scale, and impact of this heatwave is unlike anything humans have ever recorded.
Over 260 locations have seen their hottest days ever during this 70+ day heatwave.
@extremetemps has been covering this heatwave for months and has found some truly astounding stats. Many locations have experienced nearly a month (!) of their hottest days ever recorded.
This heatwave has occurred for weeks on end in one of the most densely populated areas in the world and has been acerbated by brutal humidity and hot nights.
A city with 9 million people recorded the hottest August night in Chinese history. 34.9°C.
