Global sea levels to rise 90 centimeters by 2100?

Question

how will this threaten the many coastal regions around the world?

global average temperature increased from about 13.5 *C (56.3*F) in 1880 to 14.4*C (57.9*F) in 2000. more increases in global temperatures could lead to partial meltdowns of the polar ice caps.

Answer 1

It will rise up more than 90cm because humans are the most stupid scum in the universe.

The beaches will be much SMALLER.

IF WE SURVIVE.

Answer 2

I believe most of the coastal regions will be diminished. In fact, a sea rise of 90cm, is almost a metre height and it could be severe for countries surrounded with low land.

We can see floods everywhere particularly in Asia. Floods that has not accounted for decades are showing up frequently. By 2100, sea might rise due to global warming. Climate change will happen and none of us are capable to stop this. We can do something to save ourselves...reduce the greenhouse gases (a major contributor for global warming). Promote and practice renewable energy before it is too late. We won't be alive to witness catastrophic event in future, but the next generation is going to suffer for our mistakes.

Answer 3

Wow, 90 centimeters today!?!? Yesterday it was a few inches. The day before that it was 40 ft. I really wish you all would make up your minds.  Maybe you could have a conference; no, wait, maybe there is a panel that could let us know exactly how doomed we are. Yes this is very bad news for low lying islands, but it would happen eventually any how. Don't worry too much as India and China grow they will spew enough ash to cool thing down a bit. People that live near the coast will slowly move as they have done for thousands of years.  We are people after all; we are not as immobile as some would have us believe. If you live near the coast, might I recommend something above 300 ft, as that is the worst prediction I have heard so far.

Answer 4

Sadly, it's true. If this slow increase of global warming effects doesn't stop, the world shall be submerged in water.

Answer 5

you are giving my brain a meltdown

Answer 6

Hello

Ocean Level is Rising because melting of ICE in Polar of Artica and Antartica.

Just Imagine If Sea Level Rise we all can not live in this Earth.

1.One Pilgrimage Centre Truchendur City in Bay of Bengal sea side ( Truneveli Dist Tamil Nadu India). Here Sea Water is comming deep Interior or some times sea water go back of Reverse Side.

2. All sea side cities of Kanayakumari Dist in Tamil Nadu-South India facing Sea Errosion regularly.

This two example will give us about Sea Level.

During Earthquake time Tsunami is comes upto 40 Feet and destroy many house/buildings/ships/Roads/Kill more than 3 lac people within 5 minities.

So we all have to give TOO much important for Global Warming.

If we sink in River we can swimm and reach River Banks.( Atleast some body will come to Rescue us)

If we sink in Sea. Some body/Helicopter comes and rescue us.( it depends upon God's Grace or Luck)

If the Entire world sink if sea water rise, Who will come to rescue us.

NO SOLUTION FOR THIS.

So we have to Take care about GLOBAL WARMING.

Answer 7

To answer your question, coastal regions were already experiencing erosion before this global warming "scare". We're told by alarmists that temperature doesn't matter. Does it or doesn't it? I thought it was only the climate that mattered. Alarmists know that it's not easy to fool the simple minded.

I also just read in an answer by an alarmist that global warming doesn't affect all areas at the same time.

It really sounds like alarmists try to cover all bases. Making the question fit their answer.

Answer 8

I am not an expert but this is my opinion. Are you aware that some places have tidal ranges of as much as 40feet? Some places have only a 20 foot range and some its only a foot or so. But the average change of the sea level in the middle of the ocean is only around 6 inches. This is caused by lots of very complicated factors, like the rise of the sea bed, the shape of the bay and coastal features for example, not to mention currents and then you also have to think about large volumes of water moving and what it takes for the 'momentum' to stop. Have you ever picked up a bucket of water? Its very heavy isnt it? Have you ever sat in the bath and rocked backwards and forwards and got 'that whole wave thing' going on? Well multiply the bath of water by about a gazillion.

    So if the sea level rises by a couple of inches  dont you think that it is possible that a tidal range of 40 feet could become over 50 feet etc etc? I dont think I have to paint you a picture of the possible effects of tidal ranges increasing. There are also some other factors that come into the equation, if the tide goes higer in different ports around the world at different times then 'due to the sloshing effect' would it not also go lower? This could cause previously busy harbours to close at low tide as the ships could no longer enter. There is also the issue of errosion. As larger volumes of water rush in and out of bays it would take more silt, disturbing coast lines, undermining cliff's and also dumping all the extra silt on reef's that would damage the reef life causing loss of habitat for the fish etc.

Here are some links about the effects that have already taken place due to the rise in sea level.
