The Little Ice Age was a time of cooler climate in most parts of the world. Although there is some disagreement about exactly when the Little Ice Age started, records suggest that temperatures began cooling around 1250 A.D. The coldest time was during the 16th and 17th Centuries. By 1850 the climate began to warm.

Most of the documents that record information about the Little Ice Age come from Northern Europe. The cooling was caused by a combination of decreased solar activity and numerous large volcanic eruptions. Cooling caused glaciers to advance and stunted tree growth. Livestock died, harvests failed, and humans suffered increased famine and disease.

During the Little Ice Age, average global temperatures were 1-1.5 degree Celsius (2-3 degrees Fahrenheit) cooler than they are today. The Little Ice Age was not a true ice age because it did not get cold enough for long enough to cause ice sheets to grow larger. Winter temperatures may have been more affected than summer temperatures. The cooling likely affected areas around the world but we have the most records of how it changed daily life from Europe. We know that Southern Africa and Antarctic Peninsula were relatively warm during this time.

What people observed:

• Fur trappers reported that southern Hudson Bay remained frozen for about 3 weeks longer each spring.
• Fishermen reported large amounts of sea ice in the North Atlantic.
• British people saw Eskimos paddling canoes off the coast of England.
• Poor crop yields and livestock losses led to famine in areas of Europe.

Natural records of change:

• Alpine (mountain) glaciers grew larger worldwide. In some cases, there are reports that the glacial ice engulfed mountain villages.
• Tree ring data from high latitudes shows that trees grew minimally during the cold centuries indicating short growing seasons.
• Cherry tree flowering records shows that the date of spring flowering was later in the year indicating longer winters.

Effects on people:

• Wet weather caused disease that affected people, animals and crops including the bubonic plague (also called the Black Death), which killed more than a third of Europeans.
• Farms and villages in Northern Europe were deserted as crops yielded less food. During the harshest winters bread had to be made from the bark of trees because grains would no longer grow.
• Famine in northern and Eastern Europe.
• Storms and coastal floods in Europe
• Harvests and health in England

Some of the records and events that occurred during the Little Ice Age are listed below.

• Fur trappers reported that southern Hudson Bay remained frozen for about 3 weeks longer each spring.
• Fishermen reported large amounts of sea ice floating in the North Atlantic.
• British people saw Eskimos paddling canoes off the coast of England.
• Alpine (mountain) glaciers grew larger. In some cases, the ice engulfed mountain villages.
• Winters were longer and growing seasons shorter according to tree ring data and records of cherry tree flowering.
• Wet weather caused disease that affected people, animals and crops including the bubonic plague (also called the Black Death). This disease killed more than a third of Europeans.
• Farms and villages in Northern Europe were deserted because the farmers couldn’t grow crops in the cooler climate. During the harshest winters, bread had to be made from the bark of trees because grains would no longer grow.
• Limited crops and unhealthy livestock caused famine in areas of northern and Eastern Europe. Unlike today, there was no way to transport food around the world to areas where crops had failed and people were hungry.

From about 1250 to 1850 temperatures were a bit colder than usual in most parts of the world. This time is called the Little Ice Age.

During the Little Ice Age, the average temperature of the planet was about a degree Celsius cooler than it is today (that’s 2-3 degrees Fahrenheit). Scientists think that the planet was cooler because there was less solar activity and more erupting volcanoes. The Little Ice Age was not a true ice age because it did not get cold enough for long enough to cause ice sheets to grow larger. The cooling likely affected areas around the world but we have the most records of how it changed daily life from Europe. Listed below were some of the things we know happened during the Little Ice Age.

• Fur trappers reported that southern Hudson Bay remained frozen for about 3 weeks longer each spring.
• Fishermen reported large amounts of sea ice floating in the North Atlantic.
• British people saw Eskimos paddling canoes off the coast of England.
• Alpine (mountain) glaciers grew larger.
• Winters were longer and growing seasons shorter according to tree ring data and records of cherry tree flowering.
• Wet weather caused disease that affected people, animals and crops including the plague. The plague is also called the Black Death. It was a disease that killed more than a third of Europeans.
• Because farmers couldn’t grow food, people went hungry in areas of northern and Eastern Europe. Unlike today, there was no way to transport food from far away.
