People are seeing changes all over the world. Arctic sea is melting earlier
and forming later
. Glaciers are disappearing. Heat waves, storm and floods are becoming
more extremes. Insects are emerging sooner and flowers are blooming earlier. In
some places, birds are laying eggs before they are expected and bears have stopped
hibernating. So what is going on? Our planet is getting warmer and even a small increase
in temperature can change our climate changes. We're all affected.
Earth is the only planet we know of that can support life. The reason is
different than rest of relies on a number of factors. We get just the right amount of
energy from the sun Our atmosphere is the layer of gases surrounding the earth that
absorbs ultra violet radiation and prevents temperatures from rising too high or getting
too cold. The greenhouse effect is the process that causes the surface of the earth to
be warmer than it would be if we had no atmosphere.

Why are glaciers and sea ice melting?

Why are glaciers important?
Ice acts like a protective cover over the Earth and our oceans. These bright white spots reflect excess heat back into space and keep the planet cooler. In theory, the Arctic remains colder than the equator because more of the heat from the sun is reflected off the ice, back into space.
Glaciers around the world can range from ice that is several hundred to several thousand years old and provide a scientific record of how climate has changed over time. Through their study, we gain valuable information about the extent to which the planet is rapidly warming. They provide scientists a record of how climate has changed over time.
Today, about 10% of land area on Earth is covered with glacial ice. Almost 90% is in Antarctica, while the remaining 10% is in the Greenland ice cap.
Rapid glacial melt in Antarctica and Greenland also influences ocean currents, as massive amounts of very cold glacial-melt water entering warmer ocean waters is slowing ocean currents. And as ice on land melts, sea levels will continue to rise.
