climate change basics

2.  Scientistshave warned that the
world's climate has changed a
lot, and has affected many living
and non-living things.
Many places that were warmer
are now getting colder, and many
colder regions are getting much
more colder or even warmer this
is know as Global Warming.

3.  The Earth's climate is changing in ways
that you can't easily see.
 The Earth is getting warmer because
people are adding heat-trapping gases to
the atmosphere, mainly by burning
fossil fuels. These gases are called
greenhouse gases. Warmer
temperatures are causing other changes
around the world, such as melting
glaciers and stronger storms.

4.  These changes are happening because
the Earth's air, water, and land are
all linked to the climate. The Earth's
climate has changed before, but this
time is different. People are causing
these changes, which are bigger and
happening faster than any climate
changes that modern society has ever
seen before.

5.  Climate
The total of all weather occurring over a
period of years in a given place. It is the
average weather condition of that place.
Climate tells us what it’s usually like in
the place where you live.
 Weather is what is happening outdoors in
a place at a given time. It can change a
lot within a very short time. For
example, It can be windy at night, and
sunny in the morning.

6.  Greenhouse effect
In a way, the earth is like a glasshouse. The
earth has some very important gasses in the
atmosphere that keeps us warm.
Some of these gases are water
vapour, carbon dioxide, nitrous oxide and
methane.
When the sun heats the earth, these gases
keep the heat on the earth's surface.
Without these gases, heat would escape
back into space and Earth’s average
temperature would be about 60°F colder.
