How Does a Warming Arctic Affect Global Climate? - Susan Hassol

Susan Joy Hassol, Director of Climate Communication, explains why Arctic climate is changing faster than the rest of the world. Due to global sea level rise, carbon release, reflectivity, she argues that "Arctic climate change feeds back and increases global climate change."

The reason why the Arctic is covered in ice is this.

The average global temperature has been more favorable for more ice to accumulate in the winter, than can be melted in the summer.

This is true for all large masses of ice around the world.

It took hundreds of thousands of years for ice to build up on Greenland.

Now that it's melting, this is an indication that the "average global temperature" is going up.

Ice doesn't just decide it wants to be liquid water again.

Conditions have to change.

The arctic does receive sunlight.

The tilt of the earth's axis, and it's orbit around the sun is what causes seasons.

In Canada, parts of the arctic are in darkness for 24 hours a day in winter.

The opposite is true during the summer.

You have to be up in the Territories to see it to that extent though.

Here's a little basic science 101.

Heat does not reach us from the Sun.

Light does.

Light penetrates the atmosphere, is reflected by light colored objects and is absorbed by dark objects to varying degrees. That's why you wear light colored clothes in the summer and darks in the winter.

Most elementary school children still do the experiment with different colored containers of water on the sunny window sill. Demonstrates the effect quite well.

Bullshit!!!

[Vot63]

The claim that 80% of the suns heat is reflected by the polar ice caps is bullshit. The reason that we have ice at the poles in the first place is that the poles are not reached by the sun. In order to "reflect" ,heat must first penetrate the atmosphere and when it is reflected it is reflected back into the atmosphere. Any reflected heat is trapped in the atmosphere. It doesn't matter whether that heat warms the ground or the atmosphere. An incoherent jumble of factoids isn't a "theory".

@ALBIONTYKE That is not a working link, could you try again?

[ALBIONTYKE]

@christo930 nonconcensus.wordpress.com2009­/02/03/arctic-sea-ice-increase­s-at-record-rate/ ..... That's one, you need to study for yourself with an open mind by thinking out of the box. Further research Nathen Rothchild's links to the pro man made climate warming lobby & then research his families domination of the banking world. You wont absorb it over night because its a long read, but anyone of average intelligence can work out the links as to why the scam is there. That's only for starters !

@ALBIONTYKE Why don't you just tell me a specific fact to look up, like number of acres of melting in the permafrost in 1969 and 2009 or something like that.

@ALBIONTYKE Today's satellite measurements are far more reliable than anything we had in the 60's. What I am saying is that we have a far more accurate picture of the global climate today than we did in the 60's.

@ALBIONTYKE meant "publicly available"...
