Answer:
Carbondioxide gas is responsible for global warming and climate change.
Explanation:
The climate change mostly occur due to increase in the concentration of carbondioxide gas in the atmosphere. The CFCs gases causes depletion of ozone layer in the atmosphere which is responsible for prevention of ultraviolet rays coming to the earth. The burning of fossil fuels in the vehicles and industries produces huge amount of carbondioxide gas that is released in the atmosphere that allows the sunlight to the earth but block its way after reflection which remain suspended in the lower surface causes increase in temperature which leads to global warming.
