"Centuries-old Sea Sponges Reveal Earth's Alarming 1.7°C Warming"
TL;DR Summary
A study led by researchers suggests that global temperatures have already surpassed the crucial 1.5°C warming limit, potentially reaching at least 1.7°C since pre-industrial times. The findings, based on sea sponge skeletons, indicate that human-caused ocean warming began earlier than previously assumed, and that the 2°C warming limit may be exceeded by the end of the 2020s. The study also reveals that land-air temperatures have been increasing at a faster rate than surface oceans, emphasizing the urgent need to reduce global emissions to mitigate the effects of climate change.
