analytical exposition text about the impact of global warming

Ice melts all over the world, especially in the Earth's poles. This melting includes mountain glaciers, ice covering western Antarctica and Greenland, and Arctic sea ice. Many species have been affected by rising temperatures. For example, a researcher named Bill Fraser, has tracked down Adelie's penguin population in Antarctica, which happened to shrink from 32,000 pairs to 11,000 in 30 years. Sea levels are rising faster than the last century.
