Just for comparison (& my own curiosity), Wikipedia reports world power consumption at about 150,000 TW hr/ year. That's about 5*10^20 Joules per year, so roughly 1000 times smaller.

Hmm. Was wondering why most of the observed warming was over land, but most of the heat is in the ocean surface. Of course, the very high specific heat of water is the reason! Can dump huge amounts of heat there, and get only a small change.

That fact + high circulation / mixing of ocean water seems likely to be the reason the warming over the oceans is so much more uniform.

Interesting to contrast the average temperature anomaly with the sea level change. Some correlation, but the sea level change is much more smoothed out. I don't understand why.pic.twitter.com/4Dj4I2QjAQ

I guess the sea level change is likely responsive to local changes in temperature in polar regions. Which may be more smoothed than global temperature anomaly. (But I don't see why. Also: don't have a good model of the relationship between temp change & sea-level rise, anyway)

Actually, that world energy consumption graph is really fascinating. From Wikipedia: Surprised not to see natural gas rising more. Goes against the common narrative I hear around the rise of fracking / natural gas.pic.twitter.com/MC6BB5Epuy

Curious to contrast with this paper showing evidence that CO2 emissions have peaked (mostly due to fracking):https://twitter.com/michael_nielsen/status/674738150367993856 …

TIL: Nitrous oxide - laughing gas - is an important greenhouse gas. (I wish water vapour was on this graph.)pic.twitter.com/Nk2Zaa1fTR

Interesting that methane is apparently levelling out. I don't know why.
