Answer:
Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.
Human activity affects global surface temperatures by changing Earth's radiative balance—the “give and take” between what comes in during the day and what Earth emits at night. Increases in greenhouse gases—i.e., trace gases such as carbon dioxide and methane that absorb heat energy emitted from Earth's surface and reradiate it back—generated by industry and transportation cause the atmosphere to retain more heat, which increases temperatures and alters precipitation patterns.
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 their habitats and weather primarily occur.
Answer:
Global warming is a phenomenon where the earth's average temperature rises due to increased amounts of greenhouse gases. Greenhouse gases such as carbon dioxide, methane and ozone trap the incoming radiation from the sun. ... In fact, the greenhouse effect is quite important for life on earth.Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change, since the mid-20th century humans have had an unprecedented impact on Earth's climate system and caused change on a global scale.[2]Once carbon dioxide increase, the temperature of earth increase and greenhouse trap the solar radiations in the earth. Finally, methane is another issue that causes global warming. Methane is also a greenhouse gas. Methane is more effective in trapping heat in the atmosphere that carbon dioxide by 20 times.
