Global Warming

Introduction  It was said that the Earth is so big that

you can not do significant damage, but not anymore. 

What is the most vulnerable part of the ecological system? › ATMOSPHERE 

So thin is its composition that we can change it. 

This is the basis of global warming. 

Global Warming Base The Sun's radiation comes in waves of

light that warms the Earth.  Some of the radiation that is absorbed

and warms the Earth back into space as infrared radiation. 

Part of this radiation that comes out is trapped by the atmosphere and retained.

Global Warming Base

What this does is keep the temperature and that the Earth is safe to stay alive, and that's good. 

The trouble is that by becoming thicker atmosphere, all the contamination of human beings, more infrared radiation is trapped and heats the atmosphere around the world.

Carbon Dioxide (CO2)

Roger Revelle, was among the first people who set out to measure carbon dioxide in the atmosphere. 

After 7.8 and 9 years of studies could look at the pattern that was developing in up and down every year. 

Why go up and down every year? 

Why go up and down every year?

If you see the planet's land mass is mostly in the north of Ecuador as well as most of the vegetation. 

When the Northern Hemisphere is tilted toward the sun, in spring and summer, leaves and breathe out carbon dioxide. 

This causes the amount in the atmosphere decreases. 

Why go up and down every year?

What happens when the northern hemisphere is tilted away from the sun? 

As the leaves fall and emit carbon dioxide. 

As a result, the amount in the atmosphere rises. 

Carbon dioxide was first measured from 1958 to today. 

Why go up and down every year?

1000 year to 2005 carbon dioxide has increased by over 40%. 

Global warming has increased over 80%.  When there is more carbon dioxide the

temperature is warmer.  If we travel back 650.000 years we see

that there are 7 ice ages the carbon dioxide has never gone from 300 parts per million. 

Today is beyond the natural. 

Catastrophes Temperatures are caused by: 

› Floods › Drought › Storms › Hurricanes › Tornadoes › Earthquakes

Temperature If the ocean temperature rises, storms

get stronger.  Such as: 

› Frances › Jeanne› Ivan › Tornadoes › Emily › Dennis › Katrina 

See that hot pink on the map above?

That color is new. While March was warmer

than average but not as much as, for example, 2010 or many of the months in 2010 (which broke numerous records), the Arctic (where the most warming has been predicted by climatologists) did see some pretty tremendously warm temperatures (relatively speaking).

As a result, climatologists had to add that hot pink color.

Geological changes related to climate can also cause "eruptions of methane," the release of a potent greenhouse gas, currently stored in solid form under the seabed and layers of permafrost are melting, in amounts greater than the whole carbon dioxide (CO2) from the air today.

11 things we do to stop Global Warming

Changing bulbs  Less driving  More recycling  Checking the gums  Do not use hot

water 

11 things we do to stop Global Warming

Avoid products with lots of packaging  Adjust the thermostat  Planting a tree  Turn off and unplug things electronic  Fewer pregnancies  Being part of the solution
