The term global warming refers to an increase of the Earth’s average temperature. Some theories say that climate change might be the result of human-generated carbon dioxide and other greenhouse gases. Almost 100% of the observed temperature increase over the last 50 years has been due to the increase in the atmosphere of greenhouse gas concentrations like water vapour, carbon dioxide (CO2), methane and ozone. Greenhouse gases are those gases that contribute to the greenhouse effect .The largest contributing source of greenhouse gas is the burning of fossil fuels leading to the emission of carbon dioxide.
In my opinion I think that the global warming is a serious problem because of the effect of it on earth and how temperature will increase because of that the ice blocks in the north and south pole will melt down and the sea rise up . So that will be a serious problem because some countries will drown.
