What is going on with Earth's longwave energy imbalance?

TL;DR Summary

Recorded increase in Outbound Longwave Radiation (OLR) since year 2000.

Observational Assessment of Changes in Earth’s Energy Imbalance Since 2000: 2024

Satellite observations from the Clouds and the Earth’s Radiant Energy System show that Earth’s energy imbalance has doubled from 0.5 ± 0.2 Wm−2 during the first 10 years of this century to 1.0 ± 0.2 Wm−2 during the past decade. The increase is the result of a 0.9 ± 0.3 Wm−2 increase absorbed solar radiation (ASR) that is partially offset by a 0.4 ± 0.25 Wm−2 increase in outgoing longwave radiation (OLR).

Added greenhouse gases are supposed to be decreasing the OLR.
