This is a worry!

Sattelite imagery shows rapid melting of the ice sheet in Greenland.

From The Guardian website:

The Greenland ice sheet melted at a faster rate this month than at any other time in recorded history, with virtually the entire ice sheet showing signs of thaw.
The rapid melting over just four days was captured by three satellites. It has stunned and alarmed scientists, and deepened fears about the pace and future consequences of climate change.
In a statement posted on Nasa's website on Tuesday, scientists admitted the satellite data was so striking they thought at first there had to be a mistake.

Strewth!

Hmmm if you read the article this happens once every 150 years. Your post here could be read as this is being blamed on climate change. The rag you are quoting is suggesting this but the NASA site suggests this is a normal cycle.

Paul,

I read both articles and posted them both to encourage debate. The fact is that the overwhelming majority of people get their news from a newpaper, news website or the idiotbox. I first saw this article on the Guardian website but I then checked the sourse of the story. In that spirit I placed both links so people could read for themselves.

But I do get your point, the way I constructed the post was probably not particually skillfull. Anyway, live and learn.

From NASA's website:

"Ice cores from Summit show that melting events of this type occur about once every 150 years on average. With the last one happening in 1889, this event is right on time," says Lora Koenig, a Goddard glaciologist and a member of the research team analyzing the satellite data."But if we continue to observe melting events like this in upcoming years, it will be worrisome."

Just for the record I am am concerned about AGW!
