According to scientists, there have been five ice ages in the world's history. We are currently in the Pleistocene Ice Age (also known as the Great Ice Age or the Ice Age), which began about 2.5 million years ago. These ages are characterized by extensive glaciation or the spread of glaciers and ice sheets.
The periods between ice ages are greenhouse periods when no continental glaciers are anywhere on Earth. Sea levels rise, and carbon dioxide, methane, and other greenhouse gases in the atmosphere are notably higher. We believe Earth has been in the greenhouse period for over 80% of its history.
It's important to note that Earth's climate is not static. It is a dynamic system that is constantly changing and adapting. The current warm period is a testament to Earth's ability to adapt, serving as an interglacial interlude in a continuing ice age. The first human appeared around 300,000 years ago. The homo sapiens proliferated while the Neanderthals became extinct about 40,000 years ago.
Humans lived only during this Ice Age; the first humans survived the glacial maximum because they lived near the Equator. Now, in this warming period, we live all over the Earth. Weather will continue to change as part of nature's natural cycle.
The climate change portions of this book were the weakest. This book only convinced me that climate change will change over time (the weather will be different in 1000 years). Period.
