Isn't the main cause of global warming from car emissions?

Answer 1

The greatest contributor is power generation. Most power stations are either coal, oil or gas fired; all three are fossil fuels and burning them releases large amounts of carbon dioxide and other greenhouse gases. The extraction of fossil fuels is also a large scale producer of greenhouse gases.

Power generation produces 21% of all anthropogenic greenhouse gases, industry is the second largest producer emiting 17% of the GHG's. Transportation comes in third place and accounts for 14% of GHG emissions. Cars account for a little over one third of all emissions from transport - about 5% of the overall total (other road traffic is also 5%, aircraft 3% and all other vehicles 1%).

There's diagrams here showing where the greenhouse gases come from - http://profend.com/global-warming/pages/causes.html#6

An important point to remember - different greenhouse gases have different GWPs (global warming potentials). One pound of a typical CFC leads to more global warming than one ton of carbon dioxide. Quantity alone isn't the only thing that needs to be taken into account (the equation used by climatologists is volume x GWP = contribution).

Answer 2

No. I consistently thought a by potential of fabricated from inner Combustion replaced into the poisonous gasoline Carbon Monoxide CO no longer Carbon Dioxide CO2 which has completely distinctive properties altogether. human beings expel greater CO2 than each and all the automobiles prepare and different than for water we are specially Carbon and a few different minerals. Are the government going to cut back the form of human beings on earth and shrink the sales we pay in taxes then? No, i did no longer think of so.

Answer 3

No, but that is one of the highest individual contributions we make. Factories, power plants and other commercial industries produce more than auto emissions, but that isn't something that the average person has control over, so they focus on the part of the problem that you can actually have an effect on.

Another large part of global warming is also actually methane gas released by bovines. Cow farts. It's freaky, but oddly true.

Answer 4

Cars are major contributors, but they're not the only things. Anything that releases carbon monoxide can contribute to global warming. It happens because carbon monoxide gets in the atmosphere, and slowly thickens. Over time this builds up, and while it is transparent to light, it is opaque to infrared light. Since infrared light cannot escape, it gets hotter and hotter. That is actually the way Venus is. As the first poster said, power plants can be a major source of this too, however anything that puts out greenhouse gasses contributes to it.

Answer 5

no, it is 99.9% solar related (solar flairs , internal heat of the sun , and distance and the angle that plasma strikes earth's atmosphere)-- proof is all the planets are having a global warming cycle. the other 0.1% is all the other , mostly natural, causes of warming which is mostly volcanic (about 98% of that 0.1),and about 2% of that 0.1% is slightly related to man including all the industrial and automotive and personal emissions ever in the history of earth.. how vainly stupid can we be to think it is our doing?

Answer 6

Well, it is a common belief that global warming is caused by the burning of fossil fuels, so gasolene powered cars would be included in that category. That's why we should splurge for the hybrids to protect the environment!

Answer 7

Heating and cooling of buildings causes lots of carbon dioxide emissions; The fraction of contribution is similar to that of vehicles.

Answer 8

It's a contributor but no the main cause.


the scientific consensus[7] identifies increased levels of greenhouse gases due to human activity as the main influence

Answer 9

every living and dying thing on this planet emits dreaded "greenhouse gases". i can't cite numbers, but i will go out on a limb and say that the various species on this planet far outnumber automobiles.
so, like, i don't know. what do you think?

p.s. all human output of carbon gases is @1/30 of the total output (both natural and unnatural)

Answer 10

Humans are a contributor as well since we exhale CO2 and that helps to trap greenhouse gases which lead to global warming. Though not as much a contributor as other things.
