"Sea Sponges Suggest Earth Has Surpassed 1.5°C Warming Limit"

A study of sea sponges in the Caribbean suggests that Earth may have already surpassed 1.5 degrees Celsius of warming and could reach 2 degrees Celsius by the end of the decade. The research, based on 300 years of ocean temperature records preserved within sea sponges, indicates that human-induced warming began in the mid-1860s, earlier than previously thought. The findings have significant implications for current projections of global warming, with potential mean surface warming of 1.7 degrees Celsius estimated between 2018 and 2022.
