Deep-Sea Mining Can Chase off Marine Life for Months
Even small deep-sea mining operations can have a significant effect on marine life, a new study has found, just as such mining operations are poised to begin with no industry rules in place
Climate Change Is Changing the Color of the Ocean
The world’s oceans are becoming greener with climate change, possibly because of changing amounts of plankton or other organic material in the water
Climate Change Could Stump AI Weather Prediction
Artificial intelligence taps historical weather data in forecasting, but the changing climate is complicating such efforts
