Answer:
What is Global Warming?
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.Global warming is the temperature of Earth's surface, oceans and atmosphere going up over tens to thousands of years. Average temperatures today are about 1 °C (1.8 °F) higher than before the Industrial Revolution, which started around 1750, during the Little Ice Age, an abnormally cold period.

When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. ... The absorbed energy warms the atmosphere and the surface of the Earth.
