How erupting underwater volcanoes ended 'Snowball Earth' and gave rise to lifeA new study has found that a period of rapid warming that gave rise to animal life may have been accelerated by deep-sea volcanoes.
Why are these sea turtles flying south for the winter?Warm December weather meant hundreds of sea turtles along the US east coast were caught in cold winter weather. So a network of aquariums, biologists, and volunteers in Boston and in North Carolina have been moving them south.
Temperatures rising: How humanity's heat output affecting our oceansScientists have found that the amount of man-made heat absorbed by the world’s oceans has doubled over the last 18 years, causing water temperatures to rise and more heat to be trapped across Earth's climate.
