We well may see extremes, not just in climate,
Change in the earth is inclusive of many forms.
Redistribution of climate is a very likely future as so many things happen. The recent occurrence of earth quakes can also trigger climate change.
We see them obviously change our landscape, however they also affect the ocean floor and can be a warning of volcanic eruptions, possibly to come.
How the ocean currents affect climate is an entire study of itself, redistributing thermal currents across the globe. We do have to expect this kind of change will happen, as it has happened before, however these changes will most likely not be what was, and with the complexity of climate, earth and ocean changes, solar and human emissions and so on, we cannot expect the past to predict our future.
This is the trouble with a hot year or a cold winter, in essence averaging out change. To say on average, a 5 degree change colder can mean an ice age, is a reality.
Several things can trigger this. To have a 3 degree warmer change will indeed trigger precipitation and redistribution of water across the globe.
About the only thing we can say is going to happen, is the climate will change.
How where and when obviously isn't something we can predict any more than this record cold winter we just had.
None of the computer model climate change predictions had this correct, however.... the farmer's Almanac did, the trees predicted it, and the cycles of 20 and 30 years were due.
