re: How climate change could swallow Louisiana's Avery Island

I hate how people try to dumb it down to one simple cause.
The retreat of our coastline has a variety of causes and will require a variety of solutions to counteract.
The longer we delay the solutions by arguing its existence or cause will only see us lose even more valuable coastline ecosystems.

I'll trust the guys who've been working there and looking at the same depth markers for decades over people who've faked data and been busted doing it more than once.
You expect those guys to notice less than 1.25" of sea level rise over the last 30 years?
Come on man.
Scientist also estimate sea levels 100 million years ago were 750 feet higher than they are today. The reason for the rise is where you should be skeptical. The actual rise itself isn't debatable.

If sea level is rising, why isn't it rising at the same levels all along the coast? Why is it only "rising" in areas with severe subsidence and sediment deprivation issues?
Maybe it's because global mean sea level rise due to climate change is a crock of sh%t and that Louisiana's coastal erosion issues are caused by a completely different source called the Army Corps of Engineers.

but to think that we as humans aren't having a significant effect on the change cycle is asinine
But how much 1%, 5%, 50%? We don't know, but climate change people will tell you it's all humans fault. We have no idea if that's true or not which makes their arguement disingenuous and disqualifies their opinion. I'm willing to listen if we can figure it out, but them acting like they know the answer it just as dumb as people that say the climate isn't changing.

Well that's stated in the article too..

If a single fisherman along the coast said the sea level had changed even a little bit over the past few decades, this would be believable.
wtf?

It's ok when that cause is probably contributing at least 90%. It's clearly the largest cause by all actual measures.

People on the poli board said its fake news

I totally agree. I'm just saying it is frustrating seeing posters claim a singular cause or debunk one part of the equation all in the name of fulfilling their preconceived bias towards the subject.

If conditions were equal throughout the globe you would see an even distribution of water but instead you have factors that affect water volume distribution such as:
Location of the source of the additional liquid water in our seas
Earth's gravity
Lunar Gravity
Ocean currents
Sea Temperatures
Volcanoes
Wind
Ease at which to settle
One additional (minor) factor to global sea level rise is the mass of the existing ice actually has a slight gravitational pull. As the mass of the existing ice lessens so does its gravitational pull meaning water molecules that were held closer to the ice are now released

This.
I've ready many studies which say that this is one of the main contributing factors towards erosion. Every time someone is complaining of climate change and the effects on the coast, I mention this and you can tell it never crossed their mind.
Louisiana isn't going under water, it's simply (not so simply) eroding.

It is fake news...I grew up on a farm in Bob Acres, LA...to say that the highest point in the gulf coast will be swallowed up is dumb.
The marshland around it has been being washed away by erosion but Avery island will just finally be a real expensive island!!!!

quote:None of which has one damn thing to do with climate change. It has to do with channel dredging, and erosion.
"The Avery Island marshes are retreating by around 30ft a year as salt water seeps in, ushered in by canals dug by the oil and gas industry and the level of the land itself, which is gradually sinking by around a third of an inch a year. The salty brine kills off vegetation, loosens soils and accelerates erosion."

As someone who deals with this stuff daily, believe me relative sea level rise is occurring. Obviously this accounts for sinking and rising water levels. Not to go all green, but water levels have risen somewhat

So if we all agree man changed the way our coastline protects itself, why are we so skeptical humans could impact the global ecosystem in other ways?

Being that I have property that just about touches theirs, Hurricane Rita did 99% of the damage to the marsh and it’s not going to recover.
Our family also had litigation against some major O&G companies regarding accelerated degradation and contamination of water quality and soil quality due to their gross neglegant practices. We win the lawsuit, 10 years of litigation, judge finds each company guilty and orders only lawyers fees and court cost be paid.
We wanted all old canals and location canals to be closed off to saltwater intrusion. Nothing was done at all. There was video of a certain operator discharging 10,000 BBL of saltwater brine directly out of tank batteries into the open canals killing off all fish and vegetation. Another saltwater brine pipeline ruptured in our 46 acre impoundment and 196 acre impoundment. Destroying all vegetation and wildlife.
But we aren’t a very large landholder out there, only 786 acres compared to the thousands help by the fine folk who bring us tobasco.

That graphic doesn't look right. The birdsfoot is by far seeing the most subsidence. Not pecan island.

The loss of the marshland is not concerning to you at all? Just wait til a hurricane hits

Something like 80-90% of global sea level rise is from to the expansion of the top 50-100m of oceans due to slightly higher global temperatures. People go crazy about glacier melts, but they're of minimal concern to sea levels.

Have you been in those parts lately? My dads house sits at 19 feet above sea level...almost every house has been raised to meet Rita specs.
I’m not concerned about that. I’m concerned that the Iberia parish levee district couldn’t pass a damn tax to create levee protection. Citizens don’t see into the future in those parts. Like 50 bucks per year could have dropped flood premiums by 750.
