"Centuries-old Sea Sponges Reveal Earth Surpassed 1.5°C Warming Limit Years Ago"

A study led by researchers suggests that Earth may have already surpassed the crucial 1.5°C warming limit, with global temperatures potentially reaching at least 1.7°C above pre-industrial levels. The study, based on sea sponge skeletons, challenges previous estimates and indicates that human-caused ocean warming began earlier than assumed. This discovery raises concerns about the urgency of reducing greenhouse gas emissions and highlights the need to take immediate action to address climate change.
