Once again, it's you that is the denier.

You deny the science you support by puffing out more CO2 with each post.

And you don't care.

Hypocrite.

Plants need CO2. Animals including humans are in many ways vital to the existence of plants. By us breathing out what they need to take in.

Well no duh.

But care to defend Spacey's hypocrisy that more CO2 is bad, but he keeps making more with each post?

That's laughable coming from the biggest "science" denier on this thread.

Oh NO, LOL.. you pulled a larry bell. an old one at that.

What would you deniers do without a guy like him? You would have to shut up, huh?

Modern science is settled on man-made CO2.

So why is Mars so cold with all that CO2? And where did it come from?

Earlier this year, the Environmental Protection Agency unveiled new proposed regulations that aim to force power plants to cut their emissions by as much 30% from 2005 levels by 2030. The EPA estimates the rule will cost approximately $5.5 billion in 2020, vs. net climate and health "benefits" of $26 billion to $45 billion to the economy.

Carbon pollution from power plants accounted for 33% of the U.S.' total greenhouse gas emissions in 2011, according to the EPA . The U.S.' carbon emissions have already fallen by about 10% since 2005 , due in part both to the recession and the natural-gas boom. The new regulations are expected to be a cornerstone toward accomplishing Obama's 2009 pledge during international climate talks of reducing U.S. carbon emissions by 17% from 2005 levels by 2020.

P.S. President Barack Obama is working to secure an international agreement on climate change that would compel countries to slash their carbon emissions.

The New York Times' Coral Davenport reports the agreement would be a "politically binding" one that would "name and shame" countries into reducing their emissions of fossil fuels.

Yahoo answers does have some good answers, if you are bale to separate the knowledge form the ignorance:

Several vital factors that you’ve forgotten to take into consideration…

The Martian atmosphere has a mass of just 25 teratonnes compared to Earth which has a mass of 5.1 petatonnes. With 95.3% of the Martian atmosphere being carbon dioxide there’s is a total atmospheric mass of 23.820 teratonnes of CO2, Earth on the other hand has 0.0396% atmospheric carbon dioxide by volume with a total mass of 2.039 teratonnes.

The Martian atmosphere has a density of just 0.6 kilopascals compared to 101.3 on Earth.

The atmospheric volume (surface area x atmospheric scale height) of Mars is 1,013,589,000 cubic kilometres, on Earth it’s a 5,610,792,000 cubic kilometres.

So rather than Mars having 243,000 times as much CO2 per unit volume than Earth it actually has 64.694 times as much.

Atmospheric concentration of CO2, or any other greenhouse gas, is not in itself a direct indicator of the heat retentive capacity of an atmosphere. Earth has an effective greenhouse effect due to the presence of water vapour within the atmosphere, without getting technical, this acts as the catalyst which enables heat to be retained by carbon dioxide and other greenhouse gases.

The Martian atmosphere is about 0.03% water vapour and as a result almost all the carbon dioxide that’s present is useless when it comes to retaining heat energy from the Sun. Earth has 30 times the amount of water vapour which gives it an much better atmosphere for retaining heat.

If Earth and Mars were equidistant from the Sun and thus receiving identical amounts of heat, then Earth would have an average temperature of 14°C and Mars would be –16C. Mars would be so much cooler due to having a fraction of the mass and density of atmosphere that Earth has and a very poor atmospheric composition in respect of heat retentive capacity.

There’s also the issue of equilibrium climate sensitivity to be taken into account, basically the point that A Modest Proposal has made concerning the relationship between atmospheric concentration and temperature.

If you want to see what happens to a planet that has 95% carbon dioxide in it’s atmosphere (96.5% actually) but unlike Mars, does have the right conditions for a strong greenhouse effect, then take a look at Venus. Despite being much further from the Sun than Mercury is, it’s the hottest place in the solar system other than the Sun itself. The surface temperature is 467°C, enough to melt lead.

The above explanation only scratches the surface, there is much more to know in order to understand the temperatures of the planetary bodies and the multitude of factors that affect them.

As to why it's there, it's a naturally occurring substance; better to ask why it's in the form of coal and gas and sedimentary rock on Earth.

Mars has ~ the same atmospheric CO2 as Earth. Being 141.6 million miles from the sun, as compared to 92.5 million miles for the Earth, Mars gets ~ 0.4 times the solar energy as the Earth gets per square foot.
