Earth’s ocean is warming at the same rate as five Hiroshima atomic bombs dropping into the water each second, according to scientists, causing the ocean to run out of oxygen, and endangering the future of millions of marine species.

Last year, the Intergovernmental Panel on Climate Change delivered a grim projection for the future of the world’s ocean, revealing how glaciers and ice sheets are melting at an unprecedented rate, threatening frequent storms and regular flooding in countries around the world. What is driving these changes in the world’s ocean?

The biggest driver of changes in the ocean at the moment is the climate emergency.…  Seguir leyendo »

Deep below the ocean surface lies a cold, hostile environment where the light of day cannot penetrate. The life-forms inhabiting this murky world grow slowly, mature late and take time to reproduce. Many species live 30 years or more, some up to the grand age of 150. Most have not yet been defined by science.

This dark void, which lies beyond any country’s national jurisdiction, is in trouble.

The world’s deep-sea catch is steadily declining, and the high vulnerability of these fish populations and diverse marine ecosystems is well documented. Last year, officials from the International Council for the Exploration of the Sea declared that in the Northeast Atlantic, 100 percent of all targeted deep-sea species have been fished “outside safe biological limits.”…  Seguir leyendo »
