Costa Rica’s forests find their voice again By

🎧Take a listen! Giacomo Delgado and his team have analyzed 16,000+ hours of audio to track forest recovery in Costa Rica. 🇨🇷
The study could help establish a direct link between #sound and #biodiversity in ecosystems around the world.

US exit from key UN climate convention deals major blow to climate fight - Geneva Solutions US president Donald Trump has decided to pull out of several international entities critical for protecting the environment and the climate, including the UN Framework Convention on Climate Change, a ...

The withdrawal of US support for the #IPCC carries risks far beyond funding. Without the US's approval of future IPCC reports, other nations may attempt to dilute the scientific findings, according to scientists such as @soniaseneviratne.bsky.social. 🌡️🏛️
