Log in to snowHeads to make it MUCH better!
Registration's totally free, of course, and makes snowHeads easier to use and to understand, gives better searching, filtering etc. as well as access to 'members only' forums, discounts and deals that U don't even know exist as a 'guest' user. (btw. 50,000+ snowHeads already know all this, making snowHeads the biggest, most active community of snow-heads in the UK, so you'll be in good company)..... When you register, you get our free weekly(-ish) snow report by email. It's rather good and not made up by tourist offices (or people that love the tourist office and want to marry it either)... We don't share your email address with anyone and we never send out any of those cheesy 'message from our partners' emails either. Anyway, snowHeads really is MUCH better when you're logged in - not least because you get to post your own messages complaining about things that annoy you like perhaps this banner which, incidentally, disappears when you log in :-)

Scientists monitoring the Kangerdlugssuaq Glacier on the east coast of Greenland, which is believed to be the fastest-moving glacier on Earth, are reporting large increases in its speed and rate of retreat.
The glacier is currently flowing at a rate of 14km per year, and its front end has retreated by 5km over the past year alone.
Glaciologists monitoring another glacier in Greenland, and the Columbia Glacier in Alaska, are reporting similar trends.

What determines it's speed?
The more snow that falls, the faster it will flow? The same as a River?
Well, the person's real but it's just a made up name, see?

Nope - things like friction. If you warm greenland by ~4*c so there is more summer surface melting - the water then percolates down to the base of the glacier, acts as lubrication and hey presto increased speed.

In the case of sea glaciers melting ice sheets in front of the glacier can significantly increase flow rates - they act as a kind of cork.
