Jun-14 2014 Knowing that solar irradiance dropped suddenly from 2003 onwards tells us the rough timing of the fall in temperature that's coming (just add a solar cycle length).  link
Jun-14 2017 Eleven years after 2004 is 2015, suggesting the cooling will start in 2015. However, 11 years is only the average delay, and the physical interpretation of the delay (see Post IV) suggests the delay is actually the length of the solar cycle - which has varied from 8 to 14 years, but averages 11 years. The current solar cycle is a long one, probably running around 13 years:...So the cooling is most likely to begin in 2017. link

The delay could be as much as 20 years, in which case the drop could be as late as 2024. Or it could occur as soon as 2014. An El Nino or La Nina could affect the timing too. At this stage, we don't know. But by the end of 2018 seems fairly likely. link
Feb-16 2017 Looking ahead a bit: cooler, possibly starting as early as 2017 link
Feb-16 2019 The length of the current solar cycle is around 13 to 14 years, so sometime around 2017 (or maybe a couple of years after) this should result in global cooling. link
Feb-16 2017 Prediction: There will be a sustained and significant fall in global temperature from about 2017 - 2022, of about 0.3 deg C. The 2020s will be cooler than the 1980s. link
