"Sea Sponges Reveal Global Warming Has Surpassed Critical Climate Threshold"
TL;DR
Scientists studying centuries-old sponges in the Caribbean Sea have found that global warming since the industrial age may be more severe than previously thought, with human activity raising global temperatures by about 1.7 degrees Celsius, rather than the commonly used value of 1.2 degrees Celsius. This new research suggests that the effects of a hotter Earth, such as deadlier heat waves and stronger storms, may occur earlier than previously predicted.
