Emissions up until this point have ensured an irreversible sea-level rise of 1.1 meters by the year 3000

A new study has found that it's too late to reverse the effects that greenhouse gas emissions will have on sea levels over the next thousand years -- but we could lessen the impact of these effects if proper changes are made. 

According to research by scientists at Vrije Universiteit Brussel, Manchester Metropolitan University and the Université catholique de Louvain, greenhouse gas emissions produced up to this point has ensured an irreversible sea-level rise of 1.1 meters by the year 3000. This number could increase, they warn, if no action is taken to reduce these levels -- and the effects could extend into thousands of years into the future.  

The research team came to this conclusion by modeling sea-level changes over thousands of years while including all of our planet's ice sheets and warming of the oceans into its projections. This includes glaciers, ice caps and the Greenland and Antarctic ice sheets. The team said this has never been done before. 

Using a climate modeling system called LOVECLIM, the team analyzed several scenarios over the next thousand years. It found that there will be a sea-level rise of at least 1.1 meters by the year 3000, but if other certain emissions scenarios were followed, it could increase to 2.1, 4.1 or even 6.8 meters. 

The study also found that the Greenland ice sheet was the cause of over half of the sea-level rises while thermal expansion of the ocean came in second place and glaciers/ice came in third. 

"Ice sheets are very slow components in the climate system; they respond on time scales of thousands of years," said Professor Philippe Huybrechts, co-author of the study. "Together with the long lifetime of greenhouse gases in the atmosphere, this inertia is the real poison on the climate system; anything we do now that changes the forcing in the climate system will necessarily have long consequences for the ice sheets and sea level.

"Ultimately, the current polar ice sheets store about 65 metres of equivalent sea level and if climatic warming will be severe and long-lasting, all ice will eventually melt. Mankind should limit the concentration of greenhouse gases at the lowest possible level as soon as possible. The only realistic option is a drastic reduction of the emissions. The lower the ultimate warming will be, the less severe the ultimate consequences will be."

In the meantime, it makes sense to try and reduce, reuse and recycle as much as possible, but not go into debt or hurt the economy doing it.

I agree with this statement absolutely. Is recycling good? Absolutely. Is trying to save energy good? Absolutely. Is trying to use less gas good? Sure.

But if I want a sports car, I should be able to buy one because that's the way a free market economy works. And these days we're building things like appliances that may use less whatever but are less effective at what they're designed to do. Namely toilets and washing machines.

Then you have all this "no lead" crap going on as if people are just sucking on their electronics. What is the result? Things break more. Resulting in even more waste from people largely throwing these things away and then having to go out and buy a new one.

Thank you,You hit it on the head!
Man I am so annoyed about these so called eco friendly whitegoods. Half flush toilets what a fkn joke,Yes I know that side is for taking a leak but usually they have smaller hole in the toilet bowl as well, So when you take a dump you have to flush 2 or 3 times which cancels out the saving on having the half flush in first place. Secondly front loading washing machines are CRAP, My next one will be a back to a top loader again, Front loader gets crap stuck in window which stinks out your washing if you forget to clean it and secondly I can't fit as many clothes in there so I have to do another load once again cancelling out the water savings from having front loader. Same can be said of many things we have now, Designed obsolescence? Or made so cheap they break after a several uses, Who cares they say as it's so cheap you just go buy another one.

Agreed. I have a sports car and don't want to see performance or choice go away. I doubt it will though, look at that sweet Tesla S car! Although, we may need to make sure Obama doesn't get a 2nd term...
