The World Meteorological Organization issued a press release about its annual Greenhouse Gas Bulletin:

Globally averaged concentrations of CO2 reached 403.3 parts per million in 2016, up from 400.00 ppm in 2015 because of a combination of human activities and a strong El Niño event. [...]

[...] Since 1990, there has been a 40% increase in total radiative forcing – the warming effect on our climate - by all long-lived greenhouse gases, and a 2.5% increase from 2015 to 2016 alone, according to figures from the US National Oceanic and Atmospheric Administration quoted in the bulletin.

[...] Atmospheric methane reached a new high of about 1 853 parts per billion (ppb) in 2016 and is now 257% of the pre-industrial level.

BBC News reported:

"The 3 ppm CO2 growth rate in 2015 and 2016 is extreme - double the growth rate in the 1990-2000 decade," Prof Euan Nisbet from Royal Holloway University of London told BBC News.

[...] Another concern in the report is the continuing, mysterious rise of methane levels in the atmosphere, which were also larger than the average over the past ten years.

The Aliso Canyon gas leak happened in 2016.

    we have woken the beast, from now on it will make little difference how much CO2 and CH4 we emit ourselves :(

    That's certainly not going to make me want climate change mitigation more. Still I have to wonder, how exactly is runaway climate change supposed to differ from the non-runaway version?
