The planet is warming up at different rates in different areas. The Arctic is warming at twice the rate of the rest of the planet, which is causing the sea ice to melt.
The Arctic is home to lots of wonderful wildlife, including polar bears, arctic foxes, walruses, seals and whales. We have lost around 40% of our polar bears in the last 10 years.
According to NASA, the polar ice caps are melting at an alarming rate of 9% per decade. The thickness of the Arctic ice has decreased by 40% since the 1960s.
The Greenland ice sheet measures around 650,000 square miles. If all of this ice melted, the sea will rise by 6 meters.
According to scientists at the U.S Center for Atmospheric Research, if the current rate of global temperature rise continues, the Arctic will be free of ice in Summer by 2040.
When ice melts, the meltwater drains into the sea. This causes sea levels to rise across the planet.
Most major cities are in low lying coastal areas. Many will be flooded when sea levels rise more than 2 meters.
By making simple changes to our lifestyles, we can slow down the melting of the ice. For example, not wasting electricity by turning off televisions, computers, tablets and lights will help to slow down climate change.
