I need to know how Co2 pollutes the atmosphere?

Question

how does Co2 pollutes the atmosphere and if you know a website about it plz tell me

Answer 1

Its not pollution persay, and it used to make up the vast majority of your atmosphere... that is until the first single celled organisms started using it in photosynthesis.  This is how it works, Co2 in the upper atmosphere reflects light (radiant heat) infrared spectrum, back to earth.  So... sunlight comes in, but it doesn't easily get out... the end result is a nice warm planet that allows you to live.  However, as we are coming out of a mini ice age, the earth is warming up and weather trends will be more as they were several hundred years ago.  As there has only been about 200 some odd years of recorded history in North America, we see these changes as bad... because we are morons who run around like chicken little.  THE SKY IS FALLING, GLOBAL WARMING, HERPES... you get the picture.

Answer 2

It is a real problem, not just a 'the sky is falling' silly political football.

These graphs tell the true picture:

From the U.S. Environmental Protection Agency: (Quote)

Carbon dioxide (CO2) concentrations in the atmosphere increased from approximately 280 parts per million (ppm) in pre-industrial times to 382 ppm in 2006 according to the National Oceanic and Atmospheric Administration's (NOAA) Earth Systems Research Laboratory, a 36 percent increase. Almost all of the increase is due to human activities (IPCC, 2007). The current rate of increase in CO2 concentrations is about 1.9 ppmv/year. Present CO2 concentrations are higher than any time in at least the last 650,000 years (IPCC, 2007). See Figure 1 for a record of CO2 concentrations from about 420,000 years ago to present. For more information on the human and natural sources of CO2 emissions, see the Emissions section and for actions that can reduce these emissions, see the What You Can Do Section.

What's Known

Scientists know with virtual certainty that:

Human activities are changing the composition of Earth's atmosphere. Increasing levels of greenhouse gases like carbon dioxide (CO2) in the atmosphere since pre-industrial times are well-documented and understood.

The atmospheric buildup of CO2 and other greenhouse gases is largely the result of human activities such as the burning of fossil fuels.

An “unequivocal” warming trend of about 1.0 to 1.7°F occurred from 1906-2005. Warming occurred in both the Northern and Southern Hemispheres, and over the oceans (IPCC, 2007).

The major greenhouse gases emitted by human activities remain in the atmosphere for periods ranging from decades to centuries. It is therefore virtually certain that atmospheric concentrations of greenhouse gases will continue to rise over the next few decades.

Increasing greenhouse gas concentrations tend to warm the planet.

What's Very Likely?

The Intergovernmental Panel on Climate Change (IPCC) has stated "Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations" (IPCC, 2007). In short, a growing number of scientific analyses indicate, but cannot prove, that rising levels of greenhouse gases in the atmosphere are contributing to climate change (as theory predicts). In the coming decades, scientists anticipate that as atmospheric concentrations of greenhouse gases continue to rise, average global temperatures and sea levels will continue to rise as a result and precipitation patterns will change.

What's Not Certain?

Important scientific questions remain about how much warming will occur, how fast it will occur, and how the warming will affect the rest of the climate system including precipitation patterns and storms. Answering these questions will require advances in scientific knowledge in a number of areas:

Improving understanding of natural climatic variations, changes in the sun's energy, land-use changes, the warming or cooling effects of pollutant aerosols, and the impacts of changing humidity and cloud cover.

Determining the relative contribution to climate change of human activities and natural causes.

Projecting future greenhouse emissions and how the climate system will respond within a narrow range.

Improving understanding of the potential for rapid or abrupt climate change.

Answer 3

CO2 goes up in the atmosphere and creates some kind of wall that reflects heat coming up from the Earth

Answer 4

Co2 is Carbon Dioxide.

Co2 is made from plants and trees, without them, we wouldn't survive this nature and world. It pollutes the atmosphere to help things live, such as plants. But otherwise, there's not much left now, we're breathing in Nitrogen and the oxygen that is left is for the plants to live for us to keep on living.
