9 essential facts about global warming



1)The leading cause of global warming is from water vapor, then carbon dioxide emissions, nitrous oxides, and chlorofluorocarbons (used in household appliances like air conditioning ).


2)Chlorofluorocarbons are expected to be eliminated and put out of use by 2030 to help slow down global warming.


3)The biggest business sectors that are contributing to global warming are the following: Industry, Transportation, Residential, Commercial, Agriculture.



4)Methane is the second biggest cause of greenhouse warming. Gas from cows is a big contributor to global warming.



5)A big enough volcano eruption could cool the earth for one or two years because sulfuric acid from the explosion would combine with water vapor to form a “shield” that would reflect some sunlight away from earth. Such an eruption would be quite catastrophic, though.



6)The coloration of aerosols (miniscule particles in the air) generally changes their relationship with the sun. Lightly colored aerosols reflect light back away from earth (as a white t-shirt) while darker aerosols generally absorb heat (as a hot asphalt road when it is sunny).



7)Generally, wispy clouds, such as cirrus clouds, trap light and thus warm the atmosphere whilst thick clouds generally reflect sunlight.



8)Ice/snow cover cools the earth by reflecting sunlight.



9)Without water vapor's effect on the atmosphere, the earth would be at below freezing temperatures.


-Global Warming- is it happening?







Is It Happening?




Yes. Earth is already showing many signs of worldwide climate change.

• Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies.

The rate of warming is increasing. The 20th century's last two decades were the hottest in 400 years and possibly the warmest for several millennia, according to a number of climate studies. And the United Nations' Intergovernmental Panel on Climate Change (IPCC) reports that 11 of the past 12 years are among the dozen warmest since 1850.

• The Arctic is feeling the effects the most. Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to the multinational Arctic Climate Impact Assessment report compiled between 2000 and 2004.

• Arctic ice is rapidly disappearing, and the region may have its first completely

ice-free summer by 2040 or earlier. Polar bears and indigenous cultures

are already suffering from the sea-ice loss.

• Glaciers and mountain snows are rapidly melting—for example, Montana's Glacier National Park now has only 27 glaciers, versus 150 in 1910. In the Northern Hemisphere, thaws also come a week earlier in spring and freezes begin a week later.

• Coral reefs, which are highly sensitive to small changes in water temperature, suffered the worst bleaching—or die-off in response to stress—ever recorded in 1998, with some areas seeing bleach rates of 70 percent. Experts expect these sorts of events to increase in frequency and intensity in the next 50 years as sea temperatures rise.

• An upsurge in the amount of extreme weather events, such as wildfires, heat waves, and strong tropical storms, is also attributed in part to climate change by some experts.

~CRY~
Rihanna
I'm not the type to get my heart broken
I'm not the type to get upset and cry'
cause I never leave my heart open
Never hurts me to say goodbye
Relationships don't get deep to me
Never got the whole in love thing
And someone can say they love me truly
But at the time it didn't mean a thing
[Chorus:]
My mind is gone, I'm spinning round
And deep inside, my tears I'll drown
I'm losing grip, what's happening
I stray from love, this is how I feel
This time was different
Felt like, I was just a victim
And it cut me like a knife
When you walked out of my life
Now I'm, in this condition
And I've, got all the symptoms
Of a girl with a broken heart
But no matter what you'll never see me cry
Did it happen when we first kissed?
'cause it's hurting me to let it go
Maybe 'cause we spent so much time
And I know that it's no more
I should've never let you hold me baby
Maybe why I'm sad to see us apart
I didn't give to you on purpose
Can't figure out how you stole my heart
[Chorus]
How did I get here with you, I'll never know?
I never meant to let it get so, personal
After all I tried to do, stay away from loving you
I'm broken hearted, I can't let you know
And I won't let it show
You won't see me cry
[x2]
This time was different
Felt like, I was just a victim
And it cut me like a knife
When you walked out of my life
Now I'm, in this condition
And I've, got all the symptoms
Of a girl with a broken heart
But no matter what you'll never see me cry
All my life...
