600-year-old marine sponge holds centuries-old climate records

Scientists used a 600-year-old marine sponge to reconstruct a record of ocean temperature in the North Atlantic revealing past volcanic activity as well as the current global warming trend from the release of carbon dioxide ...

Without ozone, the Earth might get a lot colder

The evolution of Earth's climate contains many components. And new research has shown just how critical the ozone layer is to the surface temperature of the Earth. Without an ozone layer, our planet would be 3.5 Kelvin cooler.

Corals can be 'trained' to tolerate heat stress, study finds

A new study led by researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science found that corals that underwent a stressful temperature treatment in the laboratory for 90 days were more ...

Human sewage kills imperiled coral: study

A research team from Rollins College in Florida and the University of Georgia has identified human sewage as the source of the coral-killing pathogen that causes white pox disease of Caribbean elkhorn coral. Once the most ...

Strong evidence for coronal heating theory presented

The Sun's surface is blisteringly hot at 6,000 kelvins or 10,340 degrees Fahrenheit—but its atmosphere is another 300 times hotter. This has led to an enduring mystery for those who study the Sun: What heats the atmosphere ...
