The Causes of Global Warming
Read the following passage about the causes of global warming and answer the
questions that follow in your book.
Global warming is the gradual increase in the Earth's surface
temperature caused by the emission of greenhouse gases, such as
carbon dioxide and methane, into the atmosphere. The main causes of
global warming are human activities, particularly the burning of fossil
fuels like coal, oil, and gas, and deforestation. The burning of these fuels
releases carbon dioxide and other greenhouse gases into the
atmosphere, which trap heat from the sun and cause the Earth's
temperature to rise. Deforestation, on the other hand, reduces the
number of trees that absorb carbon dioxide and produce oxygen. When
forests are cleared or burned, they release carbon dioxide into the
atmosphere, contributing to the greenhouse effect and global warming.
