Of course we are. We'd need to produce 0% emissions of any kind not to.
How much are we affecting it vs natural changes to climate over geological timeframes? Well that's were the argument begins. |
Pretty much agree with this. Our emissions are fairly small compared to nature itself and climate changes have been occurring with varying intervals based on a multitude of factors even before we were in existance. A single large volcano erupting can polute more than all the cars on earth for several years. Even massive human contributions such as agriculture and industry is small fries compared to the planet itself and it's regular regurgitation and farts.
One world ocean alone will polute several times more than all humans put together.

You're wrong, even prehistoric Super-eruptions which occur only once every several hundred thousand to millions of years, do not produce as much CO2 as the world does in one year. The combined volcanic eruptions of the world, otherwise, produce less CO2 than the US State of Ohio. The rest of your post is just silly.

Notice; "all the cars", not "all human emission". Cars make up only a tiny part of human emissions. Also note that CO2 is not the only climate polutor on earth.
Feel free, however, to think that my post is silly.
Edit; Correction; a single year of volcanic eruptions, of course, not one eruption.

CO2 makes up 84.8% of emissions, and cars make up 47% of emissions.

The worldwide average is about 10.2% for cars, the US sits the highest with around 22%, these figures include the bus and trucks for goods freight etc as well. In the UK, privately owned cars make up for around 66% of emissions, its bound to be a lot smaller in some areas and could be higher in others, the average total for car emissions is not very large in the big picture. Like here in Norway, goods freight by truck will be abnormally high since we're a rugged nation with long distances and almost no transport via railway and boats so the private emissions will be smaller, one should also account the factors of the actual cars in question, different nations drive different cars. Also, US figures are hardly representative for the global average, not even close. The rate of fossil fuel consumption in the US is abnormally high. The percentages and per capita figures are ludicrous compared to the rest of the world so using it as a reference to prove a point globally is futile in my opinion.
You know what the worst part about charts like those are? The amount of coal we're still using, its incredible. Also, the largest part of the human role in the equation is deforestiation, since we're removing the planets ability to process the gases and fumes, this is the single largest problem that nature would not incurr upon itself.
