How much will the Earth's seas rise ?

May 10, 2012 | Comment icon 41 comments

Scientists admit that they are still unable to predict where in the world sea levels will rise the most.
While most experts would agree that the melting ice caps will result in a rise in sea levels, pinpointing where in the world this will cause a problem for coastal populations remains a puzzle. Unlike a bathtub, the sea level is not uniform all around the world with expectations of higher levels in some places and lower levels in others.

"We know sea level is going to rise, but how much, and how fast, and where, we really still don't know," said Josh Willis, a climate scientist for NASA.
With a significant portion of the world's population living within close proximity to the oceans, often in large cities, rising sea levels bring the potential for devastating consequences.

Doug, I agree with most of what you have said and believe me, I'm trying to educate myself every single day. The cars comment is simple, just go for a drive. I've noticed a massive increase in the volume of traffic on the roads, especially during times we used to refer to as off-peak, that phrase simply does not exist now on our roads. As regards to wind turbines, the US is a far larger country compared to the UK and we have no room as it is, so sticking a handful of turbines up here and there is not going to do a thing. I was using the AREVA situation to show how one hand our government is pr... [More]

In the past, ice ages came and ice ages went. Not anymore. As long as humans are in charge of the climate, we will see no more ice ages. We know how to warm the planet. Even without CO2 pollution, the output of ONE CFC plant would be enough to reverse natural climate forcing, preventing an ice age. I'm not entirely sure I agree with this, are you referring to Ruddiman's argument that Humans are responsible for the Late Holocene warming? As regards to wind turbines, the US is a far larger country compared to the UK and we have no room as it is, so sticking a handful of turbines up here and ther... [More]

Most new turbine farms are to be located offshore, there is plenty of room to build more. I don't necessarily think offshore wind is necessarily the way forward however. We have the potential to source all of the UK energy needs from tidal power, if we employ simlar plants to La Rance in France, it will be much more reliable than wind is currently. That would be far better than the current situation, half a dozen wind turbines dotted here and there serves no purpose. Tidal power makes complete sense.

I agree, while wind energy is useful it's not entirely cost effective. I think the UK is planning to run a pilot study in the Bristol Channel as it has the second highest tidal range on the planet, although this was a few years ago so I have no idea if the current government has reversed that decision. If I find a link, I'll post it here! Edit: I've found a link, and it turns out the government have decided against it. http://www.decc.gov...... [More]

It shows that a few of the proposed barrages are considered as feasible, but not for publ... [More]

The cars comment is simple, just go for a drive. I've noticed a massive increase in the volume of traffic on the roads, especially during times we used to refer to as off-peak, that phrase simply does not exist now on our roads. I used to live just north of Denver (after Durango). Denver's rush hour is a real mess. I always tried to go through town at "off" hours. Then I moved tp Oklahoma. Tulsa's "rush hour" is better than Denver's "off hours." So where and when you live makes a lot of difference in what you're seeing on the highways. In the US, it was Henry Ford who did in public transportat... [More]

I'm not entirely sure I agree with this, are you referring to Ruddiman's argument that Humans are responsible for the Late Holocene warming? Actually, I was referring to energy flows. CFCs have enough greenhouse effect to head off an ice age regardless of other climate forcings. Ruddiman's argument does not actually apply to this; although, he appears to have been right. Doug

I'm so bored of this subject. They said millions would be homeless by 2010 because of AGW, where are they? They said millions would be dead by 2012 because of AGW, where was that exactly? Why don't they sort out the real problems on Earth instead of all this fear spreading? Who said that exactly? Who is "they". Been following this topic for two decades and never heard about millions homeless or dead by now.

the sea level will drop, there be an ice age on the way, global warming is a big lie, you may have noticed the last couple of years they call it climate change instead, their edging their bets so they can say they got it right when the ice is upon us. Could be. Climate is an extremely complex puzzle and we're in our infancy of understanding it. I'm wondering how you're such an expert that you can make such profound predictions in the face of evidence? You should share your genius with the scientific community and show them where they are making their mistakes.

I don't post here often but I thought the summation of my understanding of this issue might help. No one in Europe or America is prepared to back the sort of strategic political decisions which are needed to arrest climate change. Simple. We are to comfortable to make the sacrifices needed to transform our society into one that actually works - to many powerful vested interests wanting us to stay the way we are. Carbon taxes and carbon trading are an attempt to use market signals to modify business and public behaviour - classic neoclassical economic theory. They will fail primarily because it... [More]
