New study finds “brutal drought and extreme heat wave that began in September 2023 transformed the lake into a steaming cauldron. The lake's waters reached 41C (106F).” 😱
Hundreds of dolphins found dead in Amazon lake were in water hotter than a jacuzzi, study finds
"You couldn't put your finger in the water," said the lead author of the study, which spotlights the impacts of planetary warming on aquatic ecosystems.

Check out our piece in @theconversation.com explaining how intraspecific trait coordination across climatic gradients helps to avoid heat stress in some (but not all) tropical tree species

Some tropical trees cool their leaves to survive the heat — but not all species have ways to cope
In full sun, tropical leaves can become much hotter than the surrounding air. Their ability to cope can be a matter of life or death.
