Foods to Avoid. When youâre feeling a bit wired, avoid foods containing caffeine, alcohol, sugars, and processed ingredients. Caffeine is a stimulant that can produce a jittery feeling that might amp up your anxiety.
The Ice Ages began 2.4 million years ago and lasted until 11,500 years ago. During this time, the earthâs climate repeatedly changed between very cold periods, during which glaciers covered large parts of the world (see map below), and very warm periods during which many of the glaciers melted.
There have been approximately 11 different ice ages that have occurred during the earthâs 4.6 billion years of existence. The last ice age was called âThe Great Ice Ageâ, and it occurred 11,000 years ago. During the âGreat Ice Ageâ over a third of the earth was covered in ice, and the air had less carbon dioxide in it.
