Tuvalu looking at legal ways to be a state if it is submerged


SYDNEY, Nov 9 (Reuters) - Tuvalu is looking at legal ways to keep its ownership of its maritime zones and recognition as a state even if the Pacific island nation is completely submerged due to climate change, its foreign minister said on Tuesday.

"We're actually imagining a worst-case scenario where we are forced to relocate or our lands are submerged," the minister, Simon Kofe, told Reuters in an interview.

Diamond hauled from deep inside Earth holds never-before-seen mineral


Within a diamond hauled from deep beneath Earth's surface, scientists have discovered the first example of a never-before-seen mineral.
Named davemaoite after prominent geophysicist Ho-kwang (Dave) Mao, the mineral is the first example of a high-pressure calcium silicate perovskite (CaSiO3) found on Earth. Another form of CaSiO3, known as wollastonite, is commonly found across the globe, but davemaoite has a crystalline structure that forms only under high pressure and high temperatures in Earth's mantle, the mainly solid layer of Earth trapped between the outer core and the crust.

Scientists figure out what happens to Earth's disappearing crust


Like a giant broken-up cookie whose pieces float atop a sea of scalding milk, Earth's outer shell is made of (less-tasty) rocky rafts that constantly bump into and dive beneath each other in a process called plate tectonics.

So what happens to those hunks of disappearing crust as they dive into Earth's milky interior?

It turns out that they get weak and bendy, like a slinky snake toy, but they don't disintegrate completely, new modeling shows. The models also suggested that plate tectonics, at least in its modern form, likely only got going in the past billion years.

Crucial Antarctic ice shelf could fail within five years, scientists say


Scientists have discovered a series of worrying weaknesses in the ice shelf holding back one of Antarctica’s most dangerous glaciers, suggesting that this important buttress against sea level rise could shatter within the next three to five years.

Until recently, the ice shelf was seen as the most stable part of Thwaites Glacier, a Florida-sized frozen expanse that already contributes about 4 percent of annual global sea level rise. Because of this brace, the eastern portion of Thwaites flowed more slowly than the rest of the notorious “doomsday glacier.”

Study shows magnetic fields can act as early warning signs for tsunamis


Every minute matters in the event of a tsunami, and over the years we have seen a number of interesting ideas around how these giant waves might be better predicted ahead of time. These include monitoring underwater sound waves triggered by earthquakes, and using submarine cables as giant seismic networks. Scientists are now throwing another possibility into the mix, showing how the magnetic fields generated by tsunamis can be detected before the massive, devastating waves make it to shore.

‘The Fuse Has Been Blown,’ and the Doomsday Glacier Is Coming for Us All


One thing that’s hard to grasp about the climate crisis is that big changes can happen fast. In 2019, I was aboard the Nathaniel B. Palmer, a 308-foot-long scientific research vessel, cruising in front of the Thwaites Glacier in Antarctica. One day, we were sailing in clear seas in front of the glacier. The next day, we were surrounded by icebergs the size of aircraft carriers.

As we later learned from satellite images, in a matter of 48 hours or so, a mélange of ice about 21 miles wide and 15 miles deep had cracked up and scattered into the sea.
