When early protohumans followed predators, they largely expanded their range across Asia, staying in the tropical and near-tropical zones, which were similar to their native environment.
See the diagram below. Essay on Global Warming.
Global warming is the term used to describe a gradual increase in the average temperature of the Earth’s atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. Even though it is an ongoing debate, it is proved by the scientists that the planet is warming.
Global Warming Slowdown: The View from Space April 16th, by Roy W. Spencer, Ph. D. The Golden State is often a harbinger of trends to come, such as recently passed fuel taxes and vehicle fees to finance long-overdue local and state transportation projects. Global Warming: The Greenhouse Effect and Our Response - Global warming (the greenhouse effect) is the increase in the temperature of Earth's weather which has become popular to many people as one of the most important danger in the universe.
