Science, from the climate scientists at NOAA:
The May global surface temperature was 1.18°C (2.12°F) above the 20th-century average of 14.8°C (58.6°F), making it the warmest May on record. This was 0.18°C (0.32°F) above the previous record from May 2020. May 2024 marked the 48th consecutive May (since 1977) with temperatures at least nominally above the 20th-century average.
And, of course, the chart:
There was also this from down the page:
The January–May global surface temperature was the warmest in the 175-year record at 1.32°C (2.38°F) above the 1901-2000 average of 13.1°C (55.5°F).
It's getting warmer out there.
I was also going through my old stuff and found this from 2009 (that's 15 years ago):
A comprehensive review of key climate indicators confirms the world is warming and the past decade was the warmest on record. More than 300 scientists from 48 countries analyzed data on 37 climate indicators, including sea ice, glaciers and air temperatures. A more detailed review of 10 of these indicators, selected because they are clearly and directly related to surface temperatures, all tell the same story: global warming is undeniable.[Emphasis added.]
Undeniable. 15 years later, still undeniable.
