elementary radiative-transfer calculations demonstrate that a natural surface global brightening amounting to ~1.9 wm–2 over the 18-year period of study would be expected – using the ipcc’s own methodology – to have caused a transient warming of 1 k (1.8 f°).

paleocene:124
the paleocene–eocene thermal maximum was an approximate 200,000 year long event where the global average temperature rose by some 5 to 8 °c (9 to 14 °f), and mid-latitude and polar areas may have exceeded modern tropical temperatures of 24–29 °c (75–84 °f).
