During the past billion years, the Earth's climate has fluctuated between warm periods-sometimes even completely ice-free-and cold periods, when glaciers scour the continents. In this article, climate scientist Kirk Maasch offers perspective on these historic changes, including the likely causes of the last great ice age-which contrary to common knowledge, we are still in the midst of.
What else can I help you with?
All of the following may help begin an ice age EXCEPT .?
Increased levels of greenhouse gases in the atmosphere are unlikely to help begin an ice age as they contribute to warming the planet, not cooling it. Other factors that could help begin an ice age include changes in Earth's orbit, volcanic eruptions, and decreases in solar radiation.
Did the meteor that landed in the Arizona desert cause the ice age?
No, the meteorite that caused the Barringer Crater in Arizona landed about 50,000 years ago had nothing to do with the ice age. The present ice age started about 2.6 million years ago and the crater was formed mid-way during the last glaciation.
What is one hypothesis for the ice age?
One hypothesis for the ice age is that changes in Earth's orbit and tilt caused variations in the amount of sunlight reaching different parts of the planet, leading to temperature changes and the growth of ice sheets.
How was the ice age formed?
The Ice Age was a long period of cold climate conditions where a large part of Earth's surface was covered in ice sheets and glaciers. It was primarily caused by changes in the Earth's orbit and tilt, leading to reduced summer temperatures and increased ice accumulation. Other factors such as volcanic activity and changes in atmospheric greenhouse gases also contributed to the onset and duration of the Ice Age.
What year did the ice age begin and end?
The present ice age began about 2.6 million years ago and it has not ended yet. We are in a warm period within an ice age. The last glaciation started about 110,000 years ago and ended about 10,000 years ago.
Is the ice age going to begin in 2010?
No because it is 2011 now and there was no ice age then

What asteroid caused the ice age?
The ice age was not caused by an asteroid impact. It was most likely due to a combination of factors such as changes in Earth's orbit and axial tilt, volcanic activity, and the release of greenhouse gases.
Why did so many people migrate during the ice age?
The ice age caused the area between Russia and Alaska to freeze into ice that people could walk on but the Asian hunters also followed the bison to the Americas for food
How did the Ice Age affect lives?
The ice age affected living things because it caused living things to extinct.Also it made it hard for living things to survive.
Why did the Paleo-indian society begin to buffalo and deer after the Ice age?
LOOK IN YOUR BOOK i suggest you do :)
How do scientistis think earths orbit relates to an ice age?
Changes in the earth's rotation can lead to an ice age. Scientists believe the earth's orbit and tilt caused the last ice age and may cause another one in the near future.
Did a comet hit earth in the ice age?
There is no concrete evidence to suggest that a comet hit Earth during the ice age. The ice age was primarily caused by variations in Earth's orbit, tilt, and wobble, as well as changes in solar radiation.
What caused the woolly mammoth to be extinct?
Either too much hunting caused the population to end, or the Ice Age was too cold for them.
Did the meteor that landed in the Arizona desert cause the ice age?
No, the meteorite that caused the Barringer Crater in Arizona landed about 50,000 years ago had nothing to do with the ice age. The present ice age started about 2.6 million years ago and the crater was formed mid-way during the last glaciation.
When did the farming begin in the Fertile crescent?
Farming began about 10,000 years ago after the last ice age.
What caused the Norse settlements in Greenland to die out during the last ice age?
They died out during a period of time known as the little ice age. Though not really an ice age, temperatures in northern Europe dropped enough to force the Norse to abandon Greenland.
