In the mid-2000s, the energy imbalance was about 0.6 watts per square metre (W/m2) on average. In recent years, the average was about 1.3 W/m2. **This means the rate at which energy is accumulating near the planet’s surface has doubled. **
The models were deliberately not measuring/predicting ALL the factors they knew were involved. Back in 1998 I asked a Scripps Institute of Oceanography speaker why the models were ignoring the methane/permafrost feedback loop and was told "we decided to focus on other things"... so yeah, inaccurate models give inaccurate predictions. Get used to hearing "it is all happening faster than we expected" from now until we are incinerated.
Exactly. No one wants to read that. It's counter-intuitive, and it goes against the prevailing narrative. But the narrative that the media repeats is based on GWP100 accounting, even though we don't have 100 years to address climate change. As Hansen and colleagues pointed out, people are not well-informed, and that's true of the people deciding climate policy as well. Ignorance and denial of the facts will continue to make the situation ever more dire.
