No, because if you read the twitter post it says: "Something is very very wrong." Where is that derived from? What the scientific theory that predicts that such a drop in the global ice sheet is very wrong? I'm not saying that something could not be wrong, but giving a graph and claiming that something is wrong is not very scientific. For all we know this could be very wrong, mildy wrong, no wrong, good etc

EDIT: For a) I took a quick look at the site but couldn't locate the graph. Again I'm not saying it's falsified, but pointing to the original source is always nice. If nothing more we could get some additional details.
