The affect is widespread complications to the world's natural ecosystems. One minute there's a covering of snow outside, the next the sun is shining. The birds can't quite make up their mind as to whether build nests or stock up on food. Those are the changes that I have observed.
In the period 985 to 1200 the Vikings thrived in Greenland. Produce such as cabbage were grown and caribou and seafood were the main protein sources.
Starting around 1285 until 1400 the climate started getting colder. Basically no crops could be grown anymore or maybe a few berries for a few months of the year and whale blubber constituted 85% of their diet.
The harsh conditions meant the settlement eventually died.
Starting in the early 2000's they discovered that crops like cabbage could finally be grown yet again in the far Southern tips of Greenland.
What does this mean for the world? Vast sections of Eastern Canada like Labrador are virtually uninhabitable. These areas will become much more livable.
During the warmer time period, there is evidence that the world was more productive in unproductive areas. For instance at that time Lake Eyre was fully filled all year due to a persistent La Nina pattern. The whole Eastern seaboard had a lot more rain and Maya, Aztec, and Inca civilizations thrived. On the contrary California suffered from severe prolonged drought as did most of southern Europe. This is partly the reason why the Vikings were rising to power during this time period. The northern countries now had ice free seas and access to new bountiful lands.
Once the little ice age returned, these settlements couldn't sustain themselves and died off, the Vikings lost power and the rise of the Ottoman Empire occurred as the Middle East became more prominent. This concluded with most of the whole Med basin being conquered by Islam, even Spain.
All of history is basically related to climate change. What's going on now is as well. There's no surprise why Canada is suddenly getting focus it's never had before...

That really is incorrect regarding potential agricultural expansion in areas of Canada. Due to basic geology, being on the Canadian Shield, there is next to no probability of farming row crops in rocky poorly drained soils that are woodsy to begin with. Plant hardiness zones will get pushed further north, and extreme weather events will become the norm along with many losers overall.
