US could see a century’s worth of sea rise in just 30 years

The seas lapping against America’s coastlines are rising ever faster and will be 10 to 12 inches higher by the year 2050, with major Eastern cities hit regularly with costly floods even on sunny days, a government report says.

The National Oceanic and Atmospheric Administration and six other federal agencies issued a 111-page report Tuesday that warns of “significant consequences” from rising seas in the next few decades, with parts of Louisiana and Texas projected to see waters a foot and a half (0.45 meters) higher.

However, the worst of the long-term sea level rise from the melting of ice sheets in Antarctica and Greenland probably won’t kick in until after 2100, the study’s lead author said.

Because of climate change, the nation’s coastlines on average will see as much sea level rise in the next 30 years as they did in the previous century , said lead author William Sweet, an oceanographer for NOAA’s National Ocean Service.

While higher seas cause much more damage when storms such as hurricanes hit the coast, they are becoming a problem even on sunny days.

Speaking of SF bay lately I’ve been savoring these delicious breakfast sandwiches out there!

Let me know when Venice is underwater.

[metmom]

I’m still waiting for some climate change expert to tell me what the ideal average temperature of the earth is supposed to be and why they picked that number.

[Mariner]

Will anyone call these commie bastards into account if it doesn’t happen?

Thought so...

[hattend]

It “could” but it won’t.

That would drown both of Obama’s ocean front houses.

[crusty old prospector]

It is closer to 200’. If you go look at an outcrop of sedimentary rocks and you see the horizontal layers exposed, those represent climate-driven rise and fall of sea level throughout geologic time.

Projections are based on measures of Relative sea level rise, and models of sea level rise based on projections of hypothetical mass melting of polar ice. We know that Absolute sea level rise is about 2 mm per year, and has been for over a century, and is not accelerating.

There is a reason why the article avoids using absolute sea level change, as it would defeat the alarmist agenda. Empirical measures suggest a sea level rise of about 50mm by 2050. IOW about an inch and a half. And that’s assuming present trends maintain. A cooling trend would slow it down to even less, and we are probably facing a cool-down any time if not already begun.

[CodeToad]

Exactly. They, of all people, would notice.

Hell, SanFranNan bought oceanfront property to retire to right down the road in Hobe Sound. She’s not very worried about it.

Yeah, but she will be dead soon. She's not concerned.

[Army Air Corps]

Bingo!

Over 15 years ago Algore said we only had 9 years left.

[Crusher138]

I was under the impression that the seas rise and fall every day. We call them tides. They are primarily caused by the moon.

The lunar calendar does not line up with the solar calendar, so measuring the high tide point on the same day of a different year will not be an accurate comparison.

When I was growing up in Fort Lauderdale, every 6 years - give or take - we would have a high tide so high it would flood our backyard.

All that being said - how would they actually determine the ocean is higher at any time? They would also have to account for any rise or fall in the land itself.

They can spout any numbers they want. It will never be definitively proved.

[Mr. Lucky]

Does the report explain how the sea level will rise faster in Texas and Louisiana than elsewhere?

[Magnum44]

Again, BS. Do the math. Sediment layers do not represent rise and fall of sea level. Who taught you that nonsense?

[dfwgator]

Or it could not.

[fatman6502002]

What a bunch of BS. Pure propaganda with not one actual fact stated.

[Tell It Right]

Agreed. I'll worry about the rising sea levels when Pisa, Italy is a seaport again like it was during the Medieval Warm Period, or Ephesus is a seaport again like it was during the Roman Warm Period and the Minoan Warm Period.

Not only is the Modern Warm Period evidently not as warm as the Medieval Warm Period and Roman Warm Period (based on historical sea levels), at least not yet. But it's possible that we're in a downward trend where each of the recent warm periods didn't get as warm as the prior ones. For example, because Pisa, Italy and Pevensey Castle in the UK had coastlines during the Medieval Warm Period but don't now, that suggests the Modern Warm Period hasn't gotten as warm as the warmest points of the Medieval Warm Period. And because Ephesus ceased to have a coastline during the Dark Age and didn't have it restored during the Medieval Warm Period, that suggests the Medieval Warm Period didn't get as warm as the Roman Warm Period and Minoan Warm Period before it (when Ephesus was a seaport city).

Summarized: yes we're in the Modern Warm Period and yes sea levels are rising a teensy weensy bit and yes it might last a couple of more centuries (assuming the Modern Warm Period lasts 400 to 600 years like the prior warm periods did). But it won't rise enough to be a big deal, just like the prior warm periods didn't. If we lived long enough to see the Modern Warm Period's maximum, I'd be surprised if that was as high as the prior warm periods.

more than 30 years. Back in the 70’s it was globull cooling

Or not.
