In 1896 Svante Arrhenius constructs the first climate model of the influence of atmospheric carbon dioxide (CO 2 ). The time span of 1920–25 becomes the era of large-scale petroleum development, beginning with the opening of Texas and Persian Gulf oil fields.View the Graphical timeline A timeline can provide additional information about life's history not visible on an evolutionary tree. These include major geologic events, climate changes, radiation of organisms into new habitats, changes in ecosystems, changes in continental positions, and major extinctions. Explore the timeline below to view some of the major events in life's history. That’s because Earth’s timeline of natural change is episodic. That means changes happen in spurts, rather than at some slow and steady pace. Take the Precambrian Era. It lasted more than 4 billion years — or for more than 90 percent of Earth’s history. It ran from Earth’s formation until life burst out some 542 million years ago.

Looking at some of its life forms, how long they lived, and when they died helps provide some scale of Earth's long existence. Grades 5 - 8 Subjects

The geologic temperature record are changes in Earth's environment as determined from geologic evidence on multi-million to billion (10 9) year time scales. The study of past temperatures provides an important paleoenvironmental insight because it is a component of the climate and oceanography of the time. Although the Earth is 4.5 billion years old, the planet didn’t really start to settle down until it was a billion years old. And life didn’t really get going until the Pre-Cambrian era (over half a billion years ago). However, it is nearly impossible for my puny human brain to relate to that much time.
