A handful of ancient sponges from deep in the Caribbean are leading some scientists to think that human-induced climate change may have started earlier and warmed the world more than they thought. They calculate that the world has already surpassed the internationally agreed goal of limiting global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) … Read more

If we can rely on sea sponges that track temperatures, climate change is much more advanced than scientists have estimated. A new study using ocean organisms called sclerosponges to measure Earth’s average temperature suggests the world has already warmed by about 1.7 degrees Celsius over the past 300 years – at least half a degree … Read more
