Question

When do they expect sea level to rise due to global warming to point where widespread flooding will occur?

Answer 1

Sea level rise is slow and steady and, like so many environmental problems, easy to ignore from year to year.  But those extra inches of sea level really matter when the next big storm arrives.

Rising sea levels, along with increased snow melt in the Himalayas and deforestation keep making the annual floods in Bangladesh worse.

Sea level rise help to chew away thousands of acres of the Louisiana bayous which probably exacerbated the flooding of New Orleans by Katrina.

The Everglades and other low lying wetlands around the world  will also 'melt' away as the sea level rises.

Eventually the sea level increase will make flood control measures in low lying cities like Amsterdam, Venice, Miami more and more difficult.   Some coral islands may just sink under the waves.  The island of Tuvalu in the Pacific already has an adhoc agreement to evacuate its citizen to New Zealand.

Answer 2

Tomorow.

Answer 3

worst estimates are 20 years, best estimates are 150 years.

Answer 4

i suppose after 15 yrs

flooding will mainly occur in europe

and lowlying regions like Shanghai & Mumbai will be submerged in sea !!!

Answer 5

i wouldn't worry about sea levels rising. if it rises enough to become a real danger we will have much larger problems such as water shortages and food shortages to deal with.

this is from the ipccs forth report and although it is slightly conservative it still gives you a good idea about the changes we are talking about.

There are six families of SRES Scenarios, and AR4 provides projected temperature and sea level rises for each scenario family.

    * Scenario B1

          o Best estimate temperature rise of 1.8 °C with a likely range of 1.1 to 2.9 °C (3.2 °F with a likely range of 2.0 to 5.2 °F)

          o Sea level rise likely range [18 to 38 cm] (7 to 15 inches)

    * Scenario A1T

          o Best estimate temperature rise of 2.4 °C with a likely range of 1.4 to 3.8 °C (4.3 °F with a likely range of 2.5 to 6.8 °F)

          o Sea level rise likely range [20 to 45 cm] (8 to 18 inches)

    * Scenario B2

          o Best estimate temperature rise of 2.4 °C with a likely range of 1.4 to 3.8 °C (4.3 °F with a likely range of 2.5 to 6.8 °F)

          o Sea level rise likely range [20 to 43 cm] (8 to 17 inches)

    * Scenario A1B

          o Best estimate temperature rise of 2.8 °C with a likely range of 1.7 to 4.4 °C (5.0 °F with a likely range of 3.1 to 7.9 °F)

          o Sea level rise likely range [21 to 48 cm] (8 to 19 inches)

    * Scenario A2

          o Best estimate temperature rise of 3.4 °C with a likely range of 2.0 to 5.4 °C (6.1 °F with a likely range of 3.6 to 9.7 °F)

          o Sea level rise likely range [23 to 51 cm] (9 to 20 inches)

    * Scenario A1FI

          o Best estimate temperature rise of 4.0 °C with a likely range of 2.4 to 6.4 °C (7.2 °F with a likely range of 4.3 to 11.5 °F)

          o Sea level rise likely range [26 to 59 cm] (10 to 23 inches)

Answer 6

It won't happen. Snow and ice levels are starting to get higher. So much for the alarmists saying polar bears are drowning.

Answer 7

You might check out this link.  It's not too bad considering it's from Wikipedia:

http://en.wikipedia.org/wiki/Sea_level_r...

Answer 8

If Al Gore and the IPCC do any more "research", I'm sure they will tell us it will happen any day now...and of course there will be people stupid enough to believe them.

Answer 9

You mean it hasn't already?  Hasn't the Earth been heating up for hundreds of years?  That is one of the unexplained phoenomena that alarmists haven't quite figured out yet.  But surely they will eventually come up with a reason why we are not flooded already.  Their new key word may end up being 'evaporation.'  lol

Read the following concerning climate change, sea levels, etc. Follow the links.

COMMON MISCONCEPTIONS ABOUT GLOBAL WARMING

The National Center for Policy Analysis

U.S. Senate Report: Over 400 Prominent Scientists Disputed Man-Made Global Warming Claims in 2007

Senate Report Debunks "Consensus"

http://epw.senate.gov/public/index.cfm?F...

"A liberal media outlet has acknowledged that global warming may have "taken a breather."



National Public Radio reports instead of warming up over the past four or five years, oceans have actually been cooling slightly. According to NPR, NASA's Jet Propulsion Laboratory has been studying the ocean with a fleet of robotic instruments that can dive 3,000 feet down and measure ocean temperature. Since the "Argo" system was fully deployed in 2003, it has recorded no warming of the global oceans, but rather "slight cooling."



Marc Morano with the Senate Environment and Public Works Committee says the cooling trend runs contrary to the claims of people promoting manmade global warming fears. But NPR -- which he describes as "an entrenched, liberal, mainstream institution" -- would rather question NASA's data, showing no ocean warming, instead of questioning the models that are predicting catastrophic sea level rise due to supposed global warming, he notes."

The Sky Is Not Falling

Holly Fretwell, an economist by training, has done her best to bring some needed critical thinking to the global-warming debate by writing “The Sky’s Not  Falling! -- Why It’s OK to Chill About Global Warming.” Aimed at 8- to 12-year-olds and their parents, it is a good, reasoned, 115-page antidote to the Chicken Little hysteria and propaganda found in the mainstream media and in places like Laurie David’s kids book “The Down-to-Earth Guide to Global Warming.” Fretwell is a research fellow who focuses on natural-resource issues and public-lands management at the free-market Property and Environment Research Center (PERC) in Bozeman, Mont.

The obsession that liberals have with global warming has gotten so out of hand that they sound like a bunch of mental patients in an asylum.

Consider for a moment what a clever strategy this is: it’s too cold outside, must be global warming. Too hot? Global warming. Hurricanes? Tornadoes? Floods? Global warming all.

Answer 11

Global warming is a myth.

Answer 12

25-100 years.

The wide range is because this is one of the least understood things in global warming.  

The question is how important "feedbacks" will be.  Things like global warming causes ice to melt, exposes dark ground, warming speeds up.

But climatologists are working hard on it, obviously it's very important.

Answer 13

the first is to the low land, like jakarta city

<a href="http://www.addmoretree.blogspot.co...  and other country that land lower than sea

Answer 14

Global warming is a myth, the world is getting colder and the ice caps are growing.

Answer 15

The answer to this question depends on who you define as "they".

I have heard estimates of anywhere from 20 years to never.

Some groups claim global warming is a myth or a scam - many blame the oil companies for funding these types of groups - in fact Exxon was funding quite a few groups, but stopped doing so last year.

A large number of scientific groups estimate noticeable change in sea level will occur by the end of the century, but they are generally talking about changes of up to 3 feet.

What is the very worst cast scenario? What if all the ice  melts on both poles? Will it be like in the movie Water World where there was practically no land at all? No, it would be very bad if all ice melted, but the total sea level would rise about 200 feet - bad if you are on the coast, but hardly noticeable if you live in Denver Colorado. And this is extremely unlikely - as the average temperature in Antarctica is way below zero.  If the earth warms enough to melt the south pole, the least of our worries would be sea level increases.

Having said all this - should we be concerned?

There is an interesting youtube video series, which looks at the idea of global warming- I've included a link. Watch the video - it is worth your time - then decide if you think we need to take action now.

Answer 16

Not in my lifetime, and probably not in yours either.

Answer 17

Rising sea levels can NOT FLOOD.

Flooding only happens when heavy rains overflow rivers or levies break.

Almost everyone overlooks 'Plate Tectonics' - Islands can sink or uplift from tectonic activity.

Alarmists love to blame others for "New Orleans" - but the fact that New Orleans has been 'sinking' for over 100 years is 'Overlooked'. And they Blame Bush for what the Demos. didn't do = spend the Federally allocated money to properly reinforce their levies.

Sea levels have been rising since the end of the last ice age, thousands of years ago.  Glacier melt is NOT a NEW Phenomena - the claim that man is speeding up melting is bogus.

"Claim That Sea Level Is Rising Is a Total Fraud"
