So slightly tongue in cheek but a volcanic winter from a Yosemite or Japanese super volcano would last year's. After st helens global temps were impacted due to particulate ash.

Of course I forgot the link
I believe the eruption of a single volcano in Iceland in 2010 put out more carbon (CO) and sulfur dioxide (SO2, which may act as a kind of coolant) than the entire world had managed to save in the 5 years before that, in terms of carbon, so it's a possibility that volcanism could indeed create such a phenomenon.
As far as that solution to global warming, though, I think we're more likely to see at least a temporary 'fix' emanate from the upcoming predicted solar Grand Minimum, a period during which our Sun will become unusually cool, probably starting in the 2050s.
There may have been Grand Minimums in the past, and the famed Maunder Minimum saw temperatures from 1645 to 1715 particularly low in many parts of Europe. This is the period during which London's Thames River was noted to have frozen over. Funnily, it actually warmed up Alaska and Greenland.
A Grand Minimum could see the Sun become 7% cooler than its usual minimum, which is cool enough. Such a decline would have a strong effect on Earth's global temps.
