It’s gaining ice because of global warming. Good grief - don’t you watch movies? ;-)
When there is a gain in ice, it’s global warming, when there’s a decrease in ice, it’s global warming, when there’s no change, it’s still global warming.
As per Angela Merkel, refugees flooding Europe from the Middle East is the result of global warming. Terrorism is caused by global warming.
A theory that explains everything, explains nothing.
