Question

global warming - introduction, causes, impact prevention

Answer 1

1)Global Warming is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. This is a type of greenhouse effect.

2)Several points which could be taken into consideration while framing this answer are:

Global Warming is an increase in the earth's atmospheric temperatures widely due to an increase in the greenhouse effect resulting especially from pollution.

Global warming is melting of ice from poles because of the increase in the extent of carbon dioxide. If due to global warming all the ice from our poles melt into water, the water level on earth increases and submerge the land.

Another major cause of global warming is deforestation.

Sea levels are expected to rise between 7 and 23 inches (18 and 59 centimetres) by the end of the century, and continued melting at the poles could add between 4 and 8 inches (10 to 20 centimetres).

Less fresh water will be available.

Species that depend on one another may become out of sync. For example, plants could bloom earlier than their pollinating insects become active.

Natural calamities and disaster would occur at lesser frequencies and with more destructive power. Hurricanes and other storms are likely to become stronger.

Severe heat waves would lead to death of millions of people all around the world.

While the idea of swimming in a warmer ocean is pleasant to most human beings, increasing ocean temperature  could cause serious ecological damage.

Hi

GLOBAL WARMING

Global warming is a big environmental and social issue all over the world which everyone must know especially our kids and children as they are the future.

This environmental issue which we are experiencing now a days has made a hole in the ozone layer.

Global warming is a major atmospheric issue all over the world. Our earth’s surface becoming hot day by day by trapping the sun’s heat and rise in the level of atmospheric carbon dioxide. The bad effects of it increasing day by day and causing major problems to the living of human being. One majar cause of global warming is defoereatation. It has become one of the subjects of big social issues which need social awareness to a great level.

People should come forth together and try to solve it in order to save life on the earth.

The effects of global warming are the environmental and social changes caused (directly or indirectly) by human emissions of greenhouse gases. Future effects of climate change will vary depending on climate change policies and social development.

Some prevwntions which we should follow are : Use Fluorescent Light Bulbs,Switch Off Electric Appliances,Use solar energy,stop using perfumes etc.

hope it helped !
