The earth was once hot enough that nothing could live on its surface. The sun is just biding its time until it engulfs the planet in fiery destruction again. At a long enough timescale records for heat and (eventually) cold become meaningless, but the overall trends recently doesn't look great. I'd put money on this recent record being broken pretty quickly.
In the chart near the top it shows 1902 having the 4th hottest may.
