Question

what is global warming​

Answer 1

Explanation:

Global warming is that condition when the average temperature of the Earth rises due to the presence of high concentration of green house gases.

Answer 2

• Global warming is the current increase in temperature of the Earth’s surface (both land and water) as well as it’s atmosphere. Average temperatures around the world have risen by 0.75°C (1.4°F) over the last 100 years about two thirds of this increase has occurred since 1975. In the past, when the Earth experienced increases in temperature it was the result of natural causes but today it is being caused by the accumulation of greenhouse gases in the atmosphere produced by human activities.

• 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, the gradual heating of Earth's surface, oceans and atmosphere, is caused by human activity, primarily the burning of fossil fuels that pump carbon dioxide (CO2), methane and other greenhouse gases into the atmosphere

• Higher temperatures are worsening many types of disasters, including storms, heat waves, floods, and droughts.
