Detailed explanation-1: -The long-term global warming trend is largely due to human activities that have increased emissions of carbon dioxide and other greenhouse gases into the atmosphere. The planet is already seeing the effects of global warming: Arctic sea ice is declining, sea levels are rising, and wildfires are becoming more severe.

Detailed explanation-2: -According to NOAA’s 2021 Annual Climate Report the combined land and ocean temperature has increased at an average rate of 0.14 degrees Fahrenheit ( 0.08 degrees Celsius) per decade since 1880; however, the average rate of increase since 1981 has been more than twice as fast: 0.32 °F (0.18 °C) per decade.

Detailed explanation-3: -Global warming is the long-term heating of Earth’s surface 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. This term is not interchangeable with the term “climate change."

Detailed explanation-4: -The atmosphere today contains more greenhouse gas molecules, so more of the infrared energy emitted by the surface ends up being absorbed by the atmosphere. Since some of the extra energy from a warmer atmosphere radiates back down to the surface, Earth’s surface temperature rises.

Detailed explanation-5: -Global warming is the phenomenon of gradual increase in the average temperature of earth . It is caused by the release of greenhouse gases like carbon dioxide, methane, CFCs etc. into the atmosphere.
