This was stated twice in the quotes you copied. You do understand that temperatures and “global sea levels” are cyclical, right? Even if they are rising right now, they will come back down in future years.

Just realized that tejas has not responded in his own thread. Either a complete weasel, or a troll that got me to respond.....

They've gotten so many Global Warming/Climate Something or Others right so far that you folks MS will be sorely missed.

You'll be remembered by the polar bears while they dine on snail darters in the coastal flood plains of Iowa.

How much has the sea level "risen"

So now it's due to climate change? Not due to inept Corp of engineers, levees, channels, dredging, diversions, etc.?

Good one, mate. Do you have another joke?

That wouldn't have accepted for publication.

Exactly where is this rising sea level? Are we talking 1/4" and if so, how the hell do they measure that accurately?

---

It's currently rising around 1/8" per year. It's a combination of thermal expansion of the oceans and glacial melt. It's measured by local tidal gauges and satellite altimetry. Then they basically combine the two readings and come up with a global average. As for accuracy, it's around +/-0.5mm. You can have local sea level rise and you can have global sea level rise. South Louisiana has both. The land is subsiding and the sea is rising. It doesn't take a genius to understand that's a bad combo.

The smart people of the world understand that wetland loss in SELA is a very complicated issue without one cause and one solution. As always, the people of South Louisiana will stick their heads in the [sinking] sand and pretend nothing is wrong. The truth is that the area is experiencing an existential threat both from within and from outside forces it can't control. It is a real and life-altering threat that requires national hydrological and environmental cooperation today to lengthen tomorrow.

But don't worry, it's all a NWO liberal-LGBTQ hoax. It'll be fine.

What can I do to help avert this tragedy?

It's the global warming side ignoring facts on this particular issue.

What facts are they ignoring?

Sea level is rising. Fact.
SELA is sinking. Fact.

Combine those two and it's a bad outcome. Whether you believe climate change is man-made or a natural cycle of the earth, that does not change the fact that the oceans are rising. It's amazing to me how some can ignore hard facts to justify their own beliefs.

first off, state legislature and JBE, move the Plaquemines Parish seat from Pointe ala Hache to Belle Chasse (the de facto seat anyway)....abandon and buy out anyone living south of Braithwaite!!! pay off the oystermen who will pitch a fit...

blow the levees on the east bank south of Braithwaite...


there's a low spot somewhere between Jesuit Bend and Lake Hermitage that flooded due to a crevasse...

build a bridge, set up levees and open up the river there...

open up a channel from the river to Bayou Barataria...

---

All that money that went to levees surrounding St. Bernard and protecting portions of the west bank after Katrina should have gone to this type of project if they were truly interested in saving the Louisiana coast line.

But we keep electing self serving politicians and they take advantage of the "we have to do something" self serving special interest populace.

NOAA...They damn sure aren't saying 1/8" inch a year. Good grief.

Directly from NOAA:

quote:

---

Global sea level has been rising over the past century, and the rate has increased in recent decades. In 2014, global sea level was 2.6 inches above the 1993 average—the highest annual average in the satellite record (1993-present). Sea level continues to rise at a rate of about one-eighth of an inch per year.
