"Greenland's ice has practically been depleted."
Another way of making the situation sound worse than it is. I had to check the online dictionaries, and, sure enough, the word did not mean quite what I thought:
Deplete: To decrease the fullness of; use up or empty out.
So a slight reduction in ice coverage can be described as depleted (a reduction in the fullness) but most people will read it as meaning 'emptied out' i.e. all gone.
The use of 'sloppy' language may be accidental, or may be a deliberate ploy.

In response to my comment:
"Anybody who starts a discussion with a heading such as:
"It's global warming, stupid!" is immediately, and unconditionally, refusing to accept that any contra arguments may have any merit. As such, to attempt to put any reasonable arguments (unless they support the original posting) is pointless."
Stringsinger states:
First of all, the statement comes from New York's Mayor Bloomberg. Second, there are no reasonable contra arguments that have any merit whatsoever.
Firstly, what are mayor Bloomberg's scientific credentials?
Secondly, thank you for confirming my comment about your not accepting that there can be any valid contra arguments. A closed mind is not a scientific mind!
