Marine heatwaves can cause irreversible ecosystem damage and their frequency has doubled since 1982. If average global temperatures rise 3.5°C, we’ll see a jump from just fewer than four marine heat waves a year on average to a startling 122.

Heatwaves are occurring not only on the land but also in the sea, notably “The Blob” in Northeast Pacific and a shorter heatwave on Australia’s west coast in 2010 and 2011.
