Climate Caribbean Sponges Warming

This undated image provided by Amos Winter shows a sponge from the Caribbean that has been cut. This sponge, a simple animal that filters water, and a handful of other centuries-old sponges are causing some scientists to think human-caused climate change began sooner and has heated the world more than they thought. Many sponge species live long, and as they grow they record the conditions of the environment around them in their skeletons.
