Incorporate land and ice heating?

@ssmithClimate sez:

Interesting point from AR6: The global energy inventory increased by 435 [325 to 545] Zettajoules (ZJ) for the period 1971–2018 and 153 [101 to 206] ZJ for the period 2006–2018. This corresponds to an Earth energy imbalance of 0.57 [0.43 to 0.72] W m-2 for the period 1971–2018, increasing to 0.79 [0.52 to 1.06] W m-2 for the period 2006– 2018, expressed per unit area of Earth’s surface. Ocean heat uptake is by far the largest contribution and accounts for 91% of the total energy change. **Compared to AR5, the contribution from land heating has been revised upwards from about 3% to about 5%. ** Melting of ice and warming of the atmosphere account for about 3% and 1% of the total change respectively.

So, taken together, instead of all excess heat going into the ocean, 8% goes into land and ice.

Updated the above to be more complete, with reference.
