Global warming, the phenomenon of increasing average air temperatures near Earth’s surface over the past one to two centuries, happens mostly in the troposphere, the lowest level of the atmosphere, which extends from Earth’s surface up to a height of 6–11 miles. This layer contains most of Earth’s clouds and is where living things and ...

Global warming is a worldwide concern. Governments are trying to find ways to limit the amount of greenhouse gases put into the air. Individual people can help by driving less. They also can save energy by turning off unneeded lights and other electrical devices.
global warming, Increase in the global average surface temperature resulting from enhancement of the greenhouse effect, primarily by air pollution. In 2007 the UN Intergovernmental Panel on Climate Change forecast that by 2100 global average surface temperatures would increase 3.2–7.2 °F (1.8–4.0 °C), depending on a range of scenarios for ...
The rise of air temperatures near Earth ’s surface over the past one to two centuries is known as global warming. Earth has experienced periods of gradual warming and cooling throughout its existence as a result of natural causes. Such natural causes have included volcanic eruptions and variations in the Sun’s output.
Greenhouse effect, a warming of Earth’s surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapor, carbon dioxide, methane, and certain other gases in the air. Of those gases, known as greenhouse gases, water vapor has the largest effect.

GLOBAL WARMING meaning: the recent increase in the world's temperature that is believed to be caused by the increase of certain gases (such as carbon dioxide) in the atmosphere.

Global warming policy, the process by which key decisions regarding the mitigation of global warming and its effects on climate change are made or influenced by central governments. Leading climate scientists agree that many of the ongoing changes to the global climate system are largely caused by.
