The Bulletin of the American Meteorological Society just released the 2015 state of the climate. Download it here.

NOAA gives a nice summary, which I condense to its key points below.

1. Greenhouse gases were the highest on record.
2. Global surface temperature was the highest on record.
3. Sea surface temperature was the highest on record.
4. Global upper ocean heat content highest on record.
5. Global sea level rose to a new record high in 2015.
6. Tropical cyclones were well above average, overall.
7. The Arctic continued to warm; sea ice extent remained low.

If anyone still has any doubt that the earth is warming and humans are responsible, they should read this document!
