What human activity has added the most carbon to the atmosphere?

Question

I'm answering this in an open science quiz in my elementary school, and I'm not sure what the most correct answer is... Is it due to carbon emission from factories and vehicles?

Answer 1

Neither look at all the science and not spoon feed propaganda to the next generation.  Stop the Lies.  

We cant because we did not cause it because it is only changing marginally world wide. Global Warming is a trojan horse for Socialism, wake up Americans. Global warming is at the fore front because politicians found how to use a new platform to get re-elected. The world leaders use it because they found ways to make money at it. This is a made up problem just like Global Cooling in the 1970's. Wake up people. I agree we need to be more efficient with our resources, and we should fine and jail companies who are dumping into our rivers maliciously. I want to stop the raiforest destruction, but to say that global warming is a serious man made issue and we need to destroy the American economy and bow down to the rest of the world certainly does not float my boat. Follow the money on this one and you will see that it is all for political gain and grant money for those scientists who profit off of the government if global warming stays at the front of the issues. Look deep into the Keoto (sp?) Treaty, first of all they took jets to a non-central resort location. Not very environmentally concious. THen in the parameters of the treaty they have a clause that makes it so you can buy or sell polution credits. This is all about shifting wealth and breaking down the United States. This is painfully obvious, just look at peoples agenda. The earth's mean temperature has risen .6 degrees C in the past 125 years. Greenland's icecaps have gotten colder in the past 10 years. The Scientists who do not gain anything on their posisition will tell you that the earth has a natural progression and this is what we are seeing. The UN report is made up of POLITICIANS not a good spread of scientists. THere are as many or more scientists who believe that man in NOT the reason and it is over hyped, but their voice is not heard in the LIberal Mainstream Media. This issue is 99% political, and an attempt to make the USA a socialist nation, and eventually communisim. WAKE UP AMERICA, IT IS TIME TO BE AMERICANS. FOR THE PEOPLE BY THE PEOPLE. STOP THE LIES

Answer 2

Man-made carbon dioxide would be Al Gore's huge mansion's, caravans of SUV's and the private jets he uses to go all over the world to preach to gullible elementary school teachers about how they are harming the environment.

Answer 3

Burning of fossil fuels.

Answer 4

vehicles don't cause that much of a problem. I would say it would be from industry or burning.

Answer 5

Nope. Worldwide we burn more fossil fuel to produce electricity than any other usage. This is also the primary use for coal, the dirtiest fossil fuel. China and India are both building coal-fired plants as fast as they can. In the U.S. electrical conservation, including home insulation and high-efficiency lighting,  gives the most 'bang for the buck' of any method of carbon emission mitigation.

Answer 6

Coal has the most carbon content, so I say coal mining. Not just the mining of course, but all the mined coal gets burnt, that is why they mine it, and burning it in steel mills and power generating plants releases lots of carbon dioxide.

Answer 7

Cutting down all the trees that used to cover the globe and using landfills. But your test won't have this info.

Answer 8

electricity and transport

Answer 9

coal fired electrical plants

Answer 10

Industrialization

Answer 11

Generating electric power, about 30%:
