We love seeing the purple blossoms as we drive through neighborhoods and as a bonus, these are also excellent shade trees. Trees such as the Jacaranda are a favorite at many of our nurseries. There is no doubt about it, flowering trees in shades of purple, violet, and lavender are an attractive addition to our landscape. We can still enjoy all the benefits of these flowering trees even if we have a lack of square footage. Both of these groups seem to have gone extinct before the end of the ice age.We can enjoy the beautiful sight of purple flowering trees on any size landscape! It is true.

At the beginning of the ice age, there were other species of hominins-a group that includes our immediate ancestors and our closest relatives-throughout Eurasia, such as the Neanderthals in Europe and the mysterious Denisovans in Asia. Others moved into other parts of the world, including the cold, glacial environments of Europe.Īnd they weren’t alone.

Since our species, Homo sapiens, emerged about 300,000 years ago in Africa, we have spread around the world.ĭuring the ice age, some populations remained in Africa and did not experience the full effects of the cold. Yes, people just like us lived through the ice age. Wait, there were humans during the ice age?! One is that humans hunted them into extinction when they came in contact with the megafauna. There are different ideas about why these animals went extinct. But there were also megafauna that went extinct at the end of the ice age, such as mammoths, mastodons, saber-toothed cats, and giant ground sloths. Many animals present during the ice age would be familiar to you, including brown bears, caribou, and wolves. So were savannas, or warmer grassy plains, and deserts. Steppes, or dry grassy plains, were common. Earth was also much drier, and sea levels were much lower, since most of the Earth’s water was trapped in the ice sheets. That difference might not sound like a lot, but it resulted in most of North America and Eurasia being covered in ice sheets. That’s 11 degrees cooler than the global annual average today. At its peak, when ice sheets covered most of North America, the average global temperature was about 46 degrees Fahrenheit. When most people talk about the “ice age,” they are usually referring to the last glacial period, which began about 115,000 years ago and ended about 11,000 years ago with the start of the current interglacial period.ĭuring that time, the planet was much cooler than it is now. Right now we are in the most recent ice age’s warm interglacial period, which began about 11,000 years ago. Ice sheets and glaciers melt during warmer phases, which are called interglacials, and expand during colder phases, which are called glacials. So, why isn’t the Earth covered in ice right now? It’s because we are in a period known as an “interglacial.” In an ice age, temperatures will fluctuate between colder and warmer levels. The most recent one started about 2.6 million years ago, and in fact, we are still technically in it.

The first one happened about 2 billion years ago and lasted about 300 million years. We know that the Earth has had at least five major ice ages. “How many ice ages has the Earth had, and could humans live through one?”įirst, what is an ice age? It’s when the Earth has cold temperatures for a long time-millions to tens of millions of years-that lead to ice sheets and glaciers covering large areas of its surface.
