The 2019 annual mean (~1.18ºC) is going to be surprisingly(?) close to what was predicted in Dec 2018 just based on the ENSO state (~1.16ºC). I predict 2020 will likely come in higher than 2019 (68%), with a ~40% chance of a new record high. Definitely another top 5 year.

The ENSO condition in the coming year is even more uncertain than usual, & probably more uncertain than represented in model ensembles.

Great to have someone with your gravitas here Mr Schmidt, perhaps you can help by answering a question that Richard seems to be struggling with: Please list all the factors which influence global temp. Please describe and quantify each one?

Umm... bit of a tall order in a tweet. Lots to choose from, & they all have different fingerprints & different times when they were relevant: GHGs, volcanoes, solar, orbit, continental drift, air pollution, ozone depletion, asteroid impacts, land cover change, evolution…
