Added some new friends to our saltwater tank this weekend! We added a turbo snail, a white sabae anemone, and a pygmy angelfish. I put the anemone on top of the rocks and so far it has enjoyed that spot. The pygmy angelfish has been pestered by the yellowtail damselfish we already had, but I think it has found a safe spot.
The toxic, corrosive reason #saltwater intrusion would be a catastrophe for #NewOrleans

"It would be a nightmare for any city: A massive wedge of saltwater creeping up the Mississippi River, contaminating drinking water at treatment plants one-by-one and threatening the health of hundreds of thousands of residents.
"But it’s a looming catastrophe for New Orleans, where officials estimate that tens of thousands of the city’s water pipes are made of lead.
"New Orleans is far from the only city in the US with lead pipes, but over the last few weeks it faced the possibility that, without a herculean and costly effort to stop it, saltwater could corrode those pipes and leach toxic metals into the drinking water supply."
New Orleans may escape saltwater contaminating municipal drinking water this season. But going forward, saltwater intrusion is expected to be an increasingly regular threat, not just in in South East Louisiana but many places in the US (and presumably other countries).

New Orleans declares emergency over saltwater intrusion in drinking water.
The declaration came amid concerns the saltwater, which is impacting the river because it is at such low levels, could impact the drinking water of thousands of residents in the next few weeks.

A study in North Carolina of dying #trees may represent a foreboding preview of what may come to #coastal#ecosystems worldwide.
by Jim Morrison
"As the ocean intrudes and saltwater rises, it kills trees and creates these ghost forests—bare trunks, and stumps, ashen tombstones marking a once-thriving coastal ecosystem. In North Carolina, #pine, #RedMaple, #sweetgum and bald #cypress forests are being replaced by saltmarsh. Eventually, that saltmarsh will be replaced by open water, a shift that leads to significant and complex costs to the environment and the local economy. The loss of forests will reduce carbon storage, further fueling climate change, and the agriculture industry, timber interests will suffer as saltwater moves inland."
"Overall, there is almost no ice over four years old remaining—it now comprises just 3 percent of the total ice cover. This is the same percentage as last year and contrasts starkly with the late 1980s when 30 to 35 percent of the Arctic Ocean’s ice was older than 4 years."

How many #DeepSea species in the deep ocean will survive will probably depend on how many really need #oxygen to survive.
