"Sea Sponges' Climate Records Suggest Earth Has Surpassed 1.5°C Warming"

A study published in Nature Climate Change claims that the planet may have already warmed by 1.7C since the start of the Industrial Revolution, based on data from ancient sea sponges in the Caribbean Sea. While some scientists urge caution and skepticism, the researchers argue that their findings indicate a more advanced global warming scenario than previously thought, emphasizing the need for urgent CO2 reduction. The controversial claim has sparked debate among experts, with some questioning the study's methodology and its implications for global climate targets.
