Seas could rise 6 meters even if governments curb warming: study (We'Re Doomed!!!!)

OSLO (Reuters) - Sea levels could rise by at least six meters (20 feet) in the long term, swamping coasts from Florida to Bangladesh, even if governments achieve their goals for curbing global warming, according to a study published on Thursday.

Tracts of ice in Greenland and Antarctica melted when temperatures were around or slightly higher than today in ancient thaws in the past three million years, a U.S.-led international team wrote in the journal Science.

And the world may be headed for a repeat even if governments cut greenhouse gas emissions to limit global warming to a United Nations goal of 2 degrees Celsius (3.6 Fahrenheit) above pre-industrial times.

"Present temperature targets may commit Earth to at least six meters sea level rise," the authors at the Past Global Changes project wrote. Some greenhouse gases can linger for centuries in the atmosphere.

Such a thaw would threaten cities from Beijing to London, and swamp low-lying tropical island states.

...

Thursday's study, based on studies of everything from ancient ice to fossil corals, said sea levels rose by between six and nine meters in a warm period about 125,000 years ago when temperatures were similar to those of today.

Ocean levels gained between six and 13 meters 400,000 years ago when temperatures were up to about 1C warmer than present.

And in a warm period three million years ago, sea levels were also at least six meters higher than now. The ancient shifts were probably linked to natural variations in the Earth's orbit around the sun.

sweet!

I have some property that might be waterfront when this is all over with ;)

What’s a “meter?”

"For the last hundred years, the ocean has risen 20 cm — but for the previous hundred years the ocean also has risen 20 cm and for the last 300 years, the ocean has also risen 20 cm per 100 years. So there is no unusual rise in sea level. And to be sure you understand that I will repeat it. There is no unusual rise in sea level."

BS. It was caused by greenhouse gases when man learned how to make fire.

so.....you want me to live like a stone-age pauper when, in the end, I’m going to drown anyway?

[Sasparilla]

Time to buy some cattle pasture land in the Florida panhandle before it becomes beachfront. It used to be ocean floor eons ago. Wonder why the water receded to the present coastline?

Look at NOAA’s own data on its website on tide levels. Sea level rise has remained constant for the past hundred years and they come right out and say it.

It could, it might, it ain’t. DENIER!

Thus far the raise in ocean levels has been 20 cm (8 in). Some evil scientists have proposed that this rise has been due to air pollution settling on Greenland in particular. Of course the scoffers must be drawn and quartered publicly as a warning to any free thinkers.

You know, a "Meter"...

I think it relates to the rhythmic structure of music...

I would welcome a 2 degree C drop in temperature anytime now. 15 days straight of over 100 F here in eastern Washington

Six meters is a lot more than they said it would rise if we don’t do something about “global warming”.

So I vote we do nothing about global warming and live with less increase in sea levels.

[GraceG]

They mean 6 MILLI-METERS!

The rise has already happened as the Earth warmed from the last ice age. For example, the red shading shows what was dry land during the last glacial maximum. It's all under water now in the North Sea and English Channel.

I’ll take them seriously when they start suggesting raising seawalls or nearly uninhabited below sea level areas like the Qatarra Depression, which would create a lake bigger than Lake Ontario plus arable land in northwest Egypt rather than wealth and power transfer schemes like carbon credits.

Claim That Sea Level Is Rising Is a Total Fraud

Sea levels began to rise 18k years ago at the end of the last glacial period. They have risen about 135 meters since then which is an average of 7.5 millimeters per year. That is an average of 750 mm per century (29.5 inches) which is far more than the average over the last century.

From 1880 to 2000 sea level rose about 20 cm or just under 8 inches. Far far less than the nearly 30 inches per century average over the last 18,000 years.
