"Centuries-old Sea Creatures Challenge Climate Limit Overshooting Claims"

Scientists using centuries-old sponges off the coast of Puerto Rico have concluded that the world has surpassed a crucial global warming limit and is rapidly approaching another, suggesting that global temperatures may have already warmed more than 1.5 degrees Celsius above pre-industrial levels. However, the study's findings have sparked controversy, with some scientists questioning the use of one type of sponge from one location to represent global temperatures and the potential to confuse public understanding of climate change. The study's authors argue that the pre-industrial era should be redefined, while others emphasize that regardless of the baseline, the impacts of global warming will worsen with every fraction of a degree of warming.
