2. What is Global Warming?
Global warming is the rise in the average temperature of Earth's
atmosphere and scientists are more than 90% certain that it is primarily
caused by increasing concentrations of greenhouse gases produced by
human activities such as the burning of fossil fuels and deforestation.
3. What do you mean by Green
House Gas?
A greenhouse gas is a gas in an atmosphere
that absorbs and emits radiation within the thermal infrared range. This
process is the fundamental cause of the greenhouse effect.

fuels is typically millions of years, and sometimes exceeds 650 million
years. Fossil fuels contain high percentages of carbon and
include coal, petroleum, and natural gas.
