Marine heat waves suppress nutrient use, reproductive flexibility in humpback whales
A new study led by University of Hawai'i (UH) at Mānoa researchers reveals how extreme ocean warming disrupts whale metabolism, nutrition and reproductive success and what the developing 2026–2027 El Niño could mean next. As climate change drives increasingly intense marine heat waves, scientists are uncovering how these extreme warming events disrupt the biology of humpback whales.
How sure are we
Two or more outlets reported this story and its reliability score reached 65%, so WorldPulse marks it verified. That means more than one outlet says so, not that it is proven true.
Who reported it
[Claude] Report 2 is a near-identical version of the same UH Mānoa study on marine heatwaves and humpback whale nutrition and reproduction, with no conflicting facts.
