What things have led to global warming?

Question

I don't want its not real or anything like that its for a school paper i just need some reasons it could possible by happening i have rise of carbon dioxide emitions and deforestation

Answer 1

Deforestation is contributing considerably to global warming (less trees to process carbon dioxide),even more when fire is used to clear forests.any burning process will contribute especially burning fossil fuel.Fluorocarbons can deplete the ozone layer,earth natural barrier against reducing the amount of radiation reaching the earth surface.Pollutants resulting from human activities contribute (greatly  at the rate that we are going in our society) but they are not the only one responsible for Global Warming.Natural occurrences as solar activities (solar flares) volcanic eruptions increased release of methane gas into the atmosphere (from volcanic activity and the digestive process of humans and animals) trigger higher temperatures resulting in increased evaporation,then water vapor speeds up the process because it traps the heath on the planet (it works as a magnifying lens,it will magnify the heath coming in and reduce the heath going out).

Answer 2

This has all you need to know  Good luck !http://en.wikipedia.org/wiki/Global_warm...

Answer 3

Increased solar output is one possible cause for global warming. More radiation from the sun = warmer temperatures

Answer 4

You mean global cooling?  Last year was the 54th coldest winter ever recorded, and the rockies recieved records amount of snow fall last year.  Oh wait, I guess Al Gore won't let any stories like that get on the internet since he invented that too!

Answer 5

The same things that have led to EVERY other instance of "global warming" on this planet.  1. Position of the earth in relation to the sun. 2. Natural increases (and perhaps some manmade increases this time) in CO2 and other greenhouse gas levels.

In the last few million years we have had Ice Ages followed by "global warming" followed by Ice Ages and the cycle continues. Don't believe all the hype and propaganda you're being spoon fed at school.

Answer 6

Global Warming is a natural phenomenon that has happened thousands of times in our past!   Global Warming will occur on earth with or without people living here!

Some causes theorized is earth's position from the sun, sun spots, changes in earth orbit, etc.

Because the earth actually was a few degrees cooler last year, Global Warming will be now be called "Climate Change!"    Many of the older scientists who were so hot for "Nuclear Winter" many years ago must have been  disappointed and later switched to "Global Warming" and now they are switching to "Climate Change" to cover their butts!

Man does not cause GW!    Around 20,000 years ago America was in an ice age!  Most of the U.S. was covered with ice from Canada down to around Texas. The ice melted all by itself without any help from human beings!  Our earth has been hot and it has been cold many, many times.  Only this time we have people and TV!   There are companies poised to make billions of dollars off of GW or Climate Change - "follow the money!"   (Even Gore made over 100 million dollars on his Carbon Footprint Ponzi Scheme!)

Answer 7

It probably has something to do with all the BS released by Al Gore

Answer 8

LA's smog, too many smoke machines, dying animals, anything else?
