Almost 40 million sq kilometres of ocean around south-east Asia and the Pacific – an area five times the size of Australia – was engulfed in a marine heatwave in 2024, a World Meteorological Organization (WMO) report has revealed.
WMO scientists said the record heat – on land and in the ocean – was mostly driven by the climate crisis and coincided with a string of extreme weather events, from deadly landslides in the Philippines to floods in Australia and rapid glacier loss in Indonesia.
Satellite measurements showed sea levels were rising almost 4mm per year – “significantly higher” than the global average of 3.5mm, the report said.
jellyfish population explodes under these circumstances. they are pretty much tolerant to things like these. i remember them reporting worldwide expansion of cniderians due to rising temps and or pollutions.
