The primary concern is famine.
In the 1630s, two million people died due to famine in India.
At about the same time, huge portions of Europe developed famines, including Poland, Ireland, England, France.
In the early 1660s, India went two years without a single drop of rain.
In 1680, famine killed 80,000 people in Sardinia.
A famine in the 1690s killed 15 percent of the Scottish population.
Two million dead in France during that same period.
During the same decade, more than 100,000 people died in Sweden and Estonia.
At the turn of the century, two million more people died of famine in India.
Just a few years later, Eastern Prussia lost 40 percent of its population to famine.
Look at the chart in this video to see how quickly the climate changed. We are currently experiencing changes even faster than those.
The harsh winters like 2010 in Europe, or 2013 in North America, will become more prevalent, the video continues.
This brings up some important questions.
How long before travel and commerce are interrupted?
How long before agriculture suffers like it did 400 years ago?
How long before the plagues and disease that come with famine rise again?
