The severity of Global Warming

on the EarthGlobal warming has very severe effects on the Earth like• Ice is melting worldwide,

especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.

• Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years.

• Sea level rise became faster over the last century.

• Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas.

• Precipitation (rain and snowfall) has increased across the globe, on average.
