A THOUGHT……..

• Global warming is a threat, one that will affect generations to come. The atmosphere surrounding us that supports life is a God-given gift. It must be protected.

• There is no debate among any statured scientists of what is happening. The only debate is the rate at which it is happening.

We are feeling WARM because of exceeding

Loading Target of 49 MT.Nothing to do with

GLOBAL WARNING..

In year 2050…..

What is global warming?

Global WarmingAverage increase in the Earth's temperature

causes changes in the climate.A warmer Earth may lead to changes in:

Rainfall Patterns.Rise in sea-level.Wide range of impacts on plants.Wildlife.Humans.

Global WarmingEarth has warmed about 1ºF over the past

hundred years.

The Earth could be getting warmer on its own’ but many of the world's leading scientists think that the people are helping to make the warmer.

It should NOT be confused It should NOT be confused with climate changewith climate change

GLOBAL WARMING is the increase of the

Earth’s average surface temperature due to a build-up of greenhouse gases in the atmosphere.

CLIMATE CHANGE is a broader term that

refers to long-term changes in climate, including average temperature and precipitation.

Greenhouse Effect

Greenhouse Effect

The glass walls and roof of a greenhouse allow most of the sun’s light in but do not allow most of the heat to escape. This causes the inner temperature to be warmer than outside.

Carbon-Dioxide(CO2), and

water-vapour(H2O) acts like a

greenhouse gas, trapping heat

and making the Earth warmer.

Greenhouse Effect

This chart shows the warming caused by each of the gases that human activities release.

Do not damage Ozone Layer…….

Mars has a very thin atmosphere with a weak Greenhouse effect. It’s surface is much colder than

Earth’s. In fact it’s frozen.

Venus has an intense Greenhouse effect. It’s atmosphere is thick with Carbon-Dioxide and other

gases that trap heat. Thus, Venus’ temperature is much higher than Earth’s—Hot enough to melt Lead.

How Global Warming Works

Fossil fuels (coal, oil, natural gas)

Carbon Dioxide (CO2)

Greenhouse gases

CAUSES OF GLOBAL

in

The Sun’s energy passes through the car’s windshield.

This energy (heat) is trapped inside the car and cannot pass back through the windshield, causing the inside of the car to warm up.

Example of the Greenhouse Effect

Global warming causes

Melting of glaciers

Polar Bear Extinction

Warmer waters and more hurricanes

Increased probability and intensity of droughts and heat waves

Increased Temperature

think like……

WHERE IS my habitat…!!!

BEFORE NOW

Major CONSEQUENCE of global warming is………….

GUESS WHAT !!

At some places, it

At others……

SOMEWHERE

it’s tooo…….ooo

HOT

WHEREAS At others tooo…..

COLD

Its all because of

GLOBAL WARMING

CAUSED BY WHOM…?????

WHO Is THE CULPRIT??????

WE are the ones causing It

BUT

WE needPROOF

SO Here’s the PROOF

• Gangotri Glacier

2008

Portage Glacier

• Alaska

It’s NOT too LATE

WE MUST ACT NOW !!!!

WE SHOULD DO…………

Once upon a time, there

was a life in EARTH…..

AFTERTHOUGHT….Mother Nature is healthy,

And has beauty and is wealthy

But with Global Warming in the way,

It will take Mother Nature’s beauty away

It will become hot,

Like a steaming pot

Leaves will become brown,

Then everybody will frown

We need coolness,

Not hotness

But also happiness
