Effects of Global Warming

in the future.

Global warming relates to the

increase in the average

temperature of the Earth's

surface that has been

observed in recent years,

and it is projected to

continue. It is debated as to

whether this is a natural

occurrence or whether

human activity has impacted

or accelerated it. ...

Global warming is caused by

several things, which include

man-made or anthropogenic

causes, and global warming is

also caused by natural causes.

There are many causes, some

are as follows:

Warming

Natural causes are causes

that are created by nature.

One natural cause is a

release of methane gas from

arctic tundra and wetlands.

Methane is a greenhouse

gas and a very dangerous

gas to our environment. A

greenhouse gas is a gas that

traps heat in the earth's

atmosphere. Another natural

cause is that the earth goes

through a cycle of climate

change. This climate change

usually lasts about 40,000

years.

Man-made causes probably do

the most damage to our planet.

There are many man-made

causes of global warming.

Pollution is one of the biggest

man-made problems. Pollution

comes in many shapes and

sizes. Burning fossil fuels is one

thing that causes pollution.

Fossil fuels are fuels made of

organic matter such as coal, or

oil.

Global warming will have serious impacts on the

environment and on society. Higher temperatures will cause

a melting of ice in Greenland and Antarctica. This will

accelerate the rise of sea level. The speed at which global

warming is expected to occur in the 21st century is faster

than most plant and animal species will be able to cope with.

Some will adapt but others will suffer and may become

extinct.
