The cost of damage to the world’s oceans from climate change could reach $2 trillion a year by 2100 if measures to cut greenhouse gas emissions are not stepped up, a study by marine experts said Wednesday.

Even if humankind manages to limit global warming to 2 degrees C (3.6 degrees F), as the Intergovernmental Panel on Climate Change recommends, future generations will have to deal with sea levels 12 to 22 meters (40 to 70 feet) higher than at present, according to research published in the journal Geology.

American researchers have created a robotic jellyfish, named Robojelly, which not only exhibits characteristics ideal to use in underwater search and rescue operations, but could, theoretically at least, never run out of energy thanks to it being fuelled by hydrogen.

Researchers from Swedish and American universities say that they have solved the mystery as to why giant and colossal squid have such enormous eyes, and perhaps unsurprisingly, the oversized ocular orbits are essentially a defense mechanism.

Scientists have found a large reduction in the amount of the coldest deep ocean water, called Antarctic Bottom Water, all around the Southern Ocean using data collected from 1980 to 2011.

Scientists have just concluded a short expedition aboard the JOIDES Resolution to learn more about Atlantis Massif, an undersea mountain that formed in a very different way as compared to the majority of the seafloor.

A rapid increase in shipping in the formerly ice-choked waterways of the Arctic poses a significant increase in risk to the region’s marine mammals and the local communities that rely on them for food security and cultural identity, according to an Alaska Native groups and the Wildlife Conservation Society who convened at a recent workshop.

As ocean scientists probe what ails some of the largest creatures in the sea, a wave of new research is urging them to look at the little things – specifically the tiny schooling fish that make up the cornerstone of ocean food webs.

Well, one of the reasons for living in Washington is the beautiful spring weather and it is here this week with today being 82 degrees! I must admit it is my favorite time of year.

As global warming heats up the Earth’s oceans, one ecosystem stands to be severely threatened: Coral reefs.

The seas are creeping higher as the planet warms. But how high will they go?
