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."

Money is flowing one way - from companies and governments that depend on fossil fuels to purchase opinions of those in positions of influence to be deniers of truth. http://www.achangeinthewind.com/2012/08/big-oil-ba...


So it is your belief that political/financial influence is being exerted in favor of fossil fuels, but no such political/financial influence is being exerted in the other direction? (that is how I interpret the 'flowing one way' anyways)

Let's recall some of the insults you've thrown out yourself...

Moronic
Abject moron
Fools
idiotic
asshattery

If you truly believe that there is zero political/financial influence in climate research, then all of the above applies to you.

Period.

Feel free to disagree...just remember that if you do, you're wrong.

And, just for the record, don't take this as any claim regarding the state of our climate or the research being done on it. You just appear to believe that the bullshit only flows in one direction. It doesn't.

It does, unless you can provide proof otherwise.

Which you can't. Go on. Try. I'll wait.

See the image I posted at the top of my OP. Which spells it out quite nicely.

If you're able to provide evidence that there's payola happening to get essentially all of the world's climate researchers to *pretend* that something is happening when it really isn't, then present it.
