Last summer felt really hot! There were quite a few days when most of the headlines in the news were about how the thermometer was about to break historic records in many cities. Therefore, it is not surprising that the Earth temperature change measured by NASA during the months of June and July was the highest ever recorded.
The "breaking record" headlines are following the same pattern year after year. I don't remember any time in my lifetime when global warming was such a clear and present danger!
