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."

I like the explanation shows that scientist are A. not in agreement and B. Do not have enough climate data to prove a theory one way or another. I would like to add a small fact myself that I read once during this whole greenhouse gas caused global warming theory. One average volcano explosion such as Mt. St. Helens expels the CO2 equivalent of every car driven in America in an entire year. Nature still causes a lot of its own greenhouse gases to be put in the atmosphere and where is the data supporting that Nature could be responsible for any climate change since it does seem that alot of the blame is pointed at human industrialization and really no other cause.

You can't tax the shit out of nature transfer money from nature to poor countries. Plus enviroweenies love nature more than they love themselves and their fellow humans.

Nature is god to them and they must protect their god lest he becomes angry and drowns us all in a flood. Maybe the enviroweenies can just build an ark, put all the animals in it and just let all of us evil capitalists drown. Then they can rebuild their liberal Utopia.

You can't survive by eating money. If for no other reason, that is why we need a functioning environment/biosphere.

Can your miniscule, shallow mind grasp such a concept, I wonder?

I'd like to see you stop a volcano from erupting.
