A handful of centuries-old sponges from deep in the Caribbean are leading some scientists to think that human-caused climate change is starting earlier and warming the world more than they thought. They calculate that the world has moved beyond the internationally approved goal of limiting global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) since… Read More »

If temperature-tracking sea sponges are to be trusted, climate change has progressed much further than scientists predicted. A new study using ocean organisms called sclerosponges to measure average global temperature shows that the world has already warmed by about 1.7 degrees Celsius in the last 300 years; This is at least half a degree Celsius… Read More »
