Photos of the Jakobshavn glacier taken over the course of a year reveal how it's breaking up.

Studying glacier for a year and talking about crisis... Very scientific :-(

These processes are so slow that you need hundreds of years to form any conclusions (remember about natural fluctuations).

Glaciers in Scotland or around Baltic Sea are extinct but you are not crying about it.

So, it melts in the summer and forms again in the winter? How is that "in crisis"?

[MisterMumps]

Well, in fact, human activity is estimated to produce some 6 billion tons of CO2 but other processes on Earth produce 200 billion tons, rendering anything humans produce as almost irrelevant. That's it. There is no reason to do anything, nor can anything be done, especially in ignorance of geophysical processes and dynamics. Unclear whether CO2 is significantly causal, either, upon any "warming" process occurring.

great video thanks

some sweet info here

[grraadd]

@ChristopherRDennis please do... just don't force me to pay some cunning scumbags (they still cooperate to cook data - new batch of e-mails shows that clearly) my last euros!

[ChristopherRDennis]

@CognosSquare This is incorrect information - humans emit 100

times CO2 than volcanoes - see the website

skepticalscience. com / volcanoes-and-

global-warming. htm for scientific review of the

matter. It is irresponsible to spread ill-

thought-out ideas like yours that are counter to

scientific knowledge of a very real problem we are

facing. 

[ChristopherRDennis]

@CognosSquare We are less able to do something about

this problem because a great deal of energy is

being spent instead getting people on board to

believe a problem exists

[ChristopherRDennis]

@grraadd This argument is laughable. Science takes time. Also, scientists are using many different observations concerning different variables all over the world. Every scientific academy on the planet agrees that man-made global warming is a reality. None do not (there isn't one that says there is 'another side to the story'). Look it up for yourself. If this is as serious as the scientists are warning, we need to do something about it.

well the most recent ice age is over, so i don't think they'll be growing back any time soon. this is not a crisis.

[vengencefrom1979]

current CO2 levels are at 389 ppm and rising. it wont be long before antarctica begins to thaw as fast as greenland currently is, which btw is rising out of the sea at a rate of 1 inch per year. when antarctica thaws enough it too will rise out of the sea. it is connected to every tectonic plate around the world and will crack the earths crust. this isnt doomsday bull, this is science, and quite likely the worse threat facing mankind.

and the water compresses the sea bottom causing earthquakes, why not mention a valid point.
