Ancient sea sponges at centre of controversial claim world has already warmed by 1.7C

Ocean sponges suggest Earth has warmed longer, more than thought; Some scientists dubious

In the new study, researchers figure that the world more than a decade ago blew past an internationally approved threshold more than a decade ago. Other scientists are skeptical of the study's claims.

Caribbean sea sponges suggest higher global warming levels

A recent study using ancient sea sponges indicates the Earth may have warmed more than previously estimated.Graham Readfearn reports for the Guardian.In short:Researchers used Caribbean sea sponges to reconstruct past ocean temperatures, suggesting a 1.7C increase since the Industrial Revolution.The...

‘A deeply troubling discovery’: Earth may have already passed the crucial 1.5°C warming limit

Global temperatures have already exceeded 1.5°C warming and may pass 2°C later this decade, according to a world-first study I led. The worrying findings, based on temperature records contained in sea sponge skeletons, suggest global climate change has progressed much further than previously thought. Human-caused greenhouse gas emissions drive global warming. Obtaining accurate information about the extent of the warming is vital, because it hel…

Caribbean sea sponges suggest world may already have breached key 1.5C climate threshold

Global temperatures may have already risen by 1.5C since the pre-industrial period, according to an Australian-led team of researchers. And they warn that warming could reach 2C by the end of the decade.

Ocean sponges suggest Earth has warmed longer, more than thought; some scientists dubious

By SETH BORENSTEIN AP Science Writer A handful of centuries-old sponges from the Caribbean are causing some scientists to theorize that human-caused climate change began sooner and has warmed the world nearly a degree Fahrenheit more than most scientists previously thought. In Monday’s study, researchers figure that the world more than a decade ago blew past the internationally approved threshold of limiting global warming to 1.5 degrees Celsius…
