What does the latest data show?

I am a scientist, albeit not trained as a climate scientist, but trained to review data and its interpretation very carefully. In my humble opinion, the following is some very good and revealing data. First, from Berkeley Earth, view some graphs of global temperature history which, of most significance to me, show the Earth has warmed 0.9 deg C (1.6 °F) in the past 50 years.

Next, see what has happened recently to surface and groundwater levels in the US at NASA Earth Observatory:


My conclusions? The same as most unbiased scientists; the Earth is warming at a significant rate, and predicted changes in weather patterns are causing serious water supply consequences. Is the change driven by anthropogenic carbon emissions? My view is YES, and that the science supports that conclusion with 97+% certainty.
