Limiting climate change to 2°C is not going to protect us from devastating sea level rise, a new report has found.

According to the research, freshwater from land-based ice sheets melting into the oceans is inducing feedback that is accelerating the melting of ice shelves — a loop that indicates sea level rise will continue and could be devastating at much lower temperature changes than previously thought.

The study, authored by well-known climate scientist James Hansen and 16 other researchers, will be published in Atmospheric Chemistry and Physics this week. The research explains that there is an “amplifying feedback” as polar ice melts, because as more freshwater enters the ocean, it traps warmer sea water, which melts more ice. The effect is not included in the current Intergovernmental Panel on Climate Change (IPCC) modeling but “extensive data indicate [it] is already occurring,” according to the report.

“We are underestimating the speed at which these things are beginning to happen,” Hansen, head of the Climate Science, Awareness and Solutions Program at Columbia University’s Earth Institute, said Monday on a call with reporters.

This feedback loop is separate from other accepted science, such as the ice-albedo feedback loop, in which dark-colored water and exposed ground absorb more heat than the white, reflective ice and snow they have replaced.

Imagine 21 feet of sea level change! Entire cities near the coast would be gone....Time to take this very seriously.,

First, it isn't rapid or unusual... Second, you dishonest pukes post this right after you post that this El Nino has created some Thermal expansion in the Pacific knowing full well that when the cooling trend takes over very soon that expansion will be gone.

Gawd you fear mongering pukes are so fucked up!

James Hansen is paid activist for GISS. I suspect their is a financial motive behind this "study"

Are you sure you are not mistaking beach erosion for rising seas? .............

So a wisp of CO2 is:

• causing the seas to rise,
• making them hotter and
• lower the pH down to gastric juice level

 

[Crick]

Yes, yes and not quite

Oh Gawd........another bomb thrower thread. Im shocked!!

These same bozo's were telling us 15 years ago that Miami would be under water by now!!!

The greatest extinction in our planets history was caused by a extreme release of green house gasses. The Permian was a period of SUPER Hot climate!

Who? Can you link me to this??? Miami probably won't be under water without at least three meters of sea level rise.

Convince me you're totally committed and never post here again.

How about all them Cat 5 hurricanes!

After Katrina we we're going to get one a month - or something

Oregon is nearly 70% renewable energy.... My posting doesn't harm anything. Your coal state hurts it a lot more.

They also said that global warming would cause a increase in upper level shear. Also, the last couple years have been on the warm side at nino 3.4...Which causes even more shear.

You're melting the ice caps

Epic Fail... No mid tropospheric hot spot... It does not exist thus the imbalance does not exist to cause that wind shear. Polar low is what is causing the wind shear along with ocean surface colder by 3-5 deg C in the Atlantic.

BWHAAAAAAAAAAAAAAAAA

70% that runs just 14% of the time.... Coal fired plants and hydro are keeping your dam lights on..

What about all the damage to the environment those dams cause?
