The way we measure, my hair is short, my wife's is medium and my sons is long.

And a huge article titled about rising sea levels actually admitted that the causes in many places is sinking land.

The “Battle” of May Island

Despite being known as the 'Battle of May Island' [during WWI’s ‘Operation EC1'], the events of that night represented no battle at all, but rather a catastrophic series of blunders, miscommunications, ignorance, and sheer bad luck.
It was one of the strangest battles in military history; perhaps because there were never any enemy ships involved!
To this day, it is considered one of the most unfortunate military episodes in history.

On the misty night of 31 January to 1 February 1918, five collisions occurred between eight vessels. Two submarines were lost, and three other submarines, and a light cruiser, were damaged. 104 men died, all of them Royal Navy.

Being wartime, all records relating to the ‘Battle’ of May Island were then sealed, but after the war it suited the Admiralty to keep them sealed, and in effect suppressed, and they were only reluctantly released in 1994, after surveyors for a wind farm came across the wrecks of K-4and K-17.
A memorial to those lost in the submarines was unveiled in 2002 at Anstruther on the mainland near the Isle of May.

The month’s best science images

This brittle star, Ophiojura exbodi, belongs to a newly described species, genus and family. It was found on the sea floor at a depth of more than 360 metres, at a site near New Caledonia in the Pacific Ocean. Most brittle stars have five arms, but this unusual specimen has eight, along with eight sets of teeth surrounding the circular mouth in the centre of its body. Researchers say [1] it belongs to a lineage that split from other brittle star families around 180 million years ago, in the late Triassic or Jurassic period.

I think these are Maunsell forts. Anti aircraft structures from World War 2. There are still a few of these left standing in the UK. The river Thames for example was a nice navigational lead into London for bombers, so they built a bunch of these in the estuary.

I think that one may be Shivering Sands?

Sea Snot
Rowers, near the Caddebostan shore of Turkey’s Marmara Sea, cut through a layer of marine mucilage, a green-grey sludge, that develops on the water’s surface, owing to the proliferation of microorganisms. The substance, informally dubbed sea snot, was first documented in Turkish waters in 2007. Researchers warn that the mucilage is harmful to sea life, and is likely to occur more often in future, because of climate change.

Yeah, we know - everything will be worse "because of climate change"
(even if it gets cooler? )


Actually:
"Marine mucilage, also called sea snot, "is essentially a mass of microorganisms enriched by components of excessive nutrients from untreated waste discharged into the sea.""
i.e. it's all the crap that is being dumped into the sea.

Just to add…

“ The Deepwater Horizon oil spill in the Gulf of Mexico created large amounts of sea snot. Scientists are not sure how exactly the spill caused so much sea snot to form, but one theory asserts that the sea snot could have been the result of a massive kill of microscopic marine life creating a "blizzard" of marine snow. Scientists worry that the mass of sea snot could pose a biohazard to surviving marine life in the area. It is widely believed that the sea snot left by the spill directly resulted in the loss of sea life in the Gulf of Mexico, as evidenced by a dead field of deepwater coral 11 kilometers from the Deepwater Horizon station.”

I’ve see it in some coastal areas of the Philippines where sewage is dumped in the coastal waters. And the Philippines weather has always been hot and has not changed but a TINY bit (1.5º C) for the past 100 years. There’s always been global warming since the Ice Age.

You'd think sewage eating algae would evolve to clean it up...sort of like after the cane toads were introduced in Oz, the snakes that survived to breed, for the most part had smaller mouths, and do not any longer come to grief by eating them. Also, crows have learned how to get to the still edible parts, and, like other butcher birds, are meat eaters.

Turkey struck by ‘sea snot’ because of global heating

The gloopy, mucus-like substance had not been recorded in Turkish waters before 2007. It is created as a result of prolonged warm temperatures and calm weather and in areas with abundant nutrients in the water.

The phytoplankton responsible grow out of control when nutrients such as nitrogen and phosphorus are widely available in seawater. These nutrients have long been plentiful in the Sea of Marmara, which receives the wastewater of nearly 20 million people and is fed directly from the nutrient-rich Black Sea.

“The main trigger is warming related to climate change, as phytoplankton grow during higher temperatures,” said Özdelice, noting that the seawater had warmed by 2-3C since preindustrial times. But since countering climate change requires a global and concerted effort, she urged Turkey to focus on factors it could control: overfishing and waste water discharges.

^^^^^^^^^^^^^^^^^

But, yes, we know. Stu's been a long-term AGW denier skeptic who likes nothing better than to get any thread shut down that discusses Climate Change.
