This isn't raw data. The raw data is a gigantic pile of satellite measurements. This is all of that data collapsed down into a single figure via a model (itself derived from yet more data), and the scope of that figure isn't as easy to characterize as "Antarctica did X".

So I'd cautioned you against the belief that you really have any data here. You have a single number, flagged for your attention by somebody who (presumably) believes that they can influence your conclusion in a particular direction. You can't really draw conclusions from data without gathering as much data as possible, and this single number is nowhere near complete. If this data strengthens your confidence that you understand the whole situation, then it is worse than having no data at all.
