GLOBAL

WARMING

Greenhouse gases, such as carbon dioxide, water vapor, nitrous oxide, and methane, trap heat and sunlight in the earth’s atmosphere, increasing the temperature.

Warming of the earth through carbon dioxide (CO2) being pumped into the atmosphere. Then the gases trap heat like the glass in a greenhouse. This is where the term “greenhouse effect” came from.

Tropical Forests & Grass Lands will disappear ,Ground water level will go

down and heat will increase.

Wind Warming will make cyclones, hurricanes and typhoons more violent and frequent.

Radiant heat is trapped

Our atmospheric “blanket” is over 37% “thicker” than it used to be

Increase in Green House Gas warms the planet

Decrease in Green House Gas cools the planet

Unfortunately there is a steep increase of the temperature in the last three decades

Greenhouse gases make the earth too hot, just like

Thicker blanket traps too much heat in SUMMER.

Thinner blanket is “just right.” IN SUMMER

Geographic North Pole is called the Arctic and includes almost the entire Arctic Ocean and northern areas of Europe, Asia, and North America. 

Geographic South Pole is called the Antarctic and includes the continent of Antarctica and parts of the surrounding Southern Ocean

Greenland Ice Sheet Greenland is now losing 20 percent

more mass

than it receives from new snowfall

each year.

Glacier in Argentina

This glacier of Argentina has lost more than 4 kilometres in 4 years and still losing.

Glacier in Chile

Glacier in Chile appears to be losing mass than its diminishing

400 Years Old ICE Shelf Melted in Antarctic

220 meters thick Larsen B shelf existed for at least 400 years prior to breakup

An picture is worth for thousand words

Before the warming: Glacier National Park, USA 1932

After the warming: Glacier National Park, USA 1988

Gangotri glacier has retreated more than 850 meters, in the last 25 years

It has retreated more than 76 meters from 1996 to 1999

Snow and sea ice reflect 85-90% of sun’s energy

Ocean surface and dark soil reflect only 10-20%

The Arctic Ocean could be ice-free in summer

by 2040

2001-2003 : A significant increase in the melting area has been observed along the edge of the ice cap in Greenland.

Where the whole water will go while the melting?

In Oceans

So the Oceans Water level will rise!

It is predicted that if the melting of ICE in the poles will be continuous then………
