Do you believe that humans are most responsible for increased C02 and Global Warming?

Question

Since 1800, there has been a 27% increase in atmospheric C02. During the same time there has been a 700% increase in world population.

Based on these readily available numbers, this means that the per person contribution of C02 into the atmosphere has DECLINED 99.96% since 1800. Remember, if you agree that humans are responsible for the buildup of C02 then they must also be responsible for the reduction.

So, if C02 isn't causing global warming then why are we in such a hurry to reduce it more?

Answer 1

no...AlGores next movie is "man killed the dinosaurs with pollution."    why campfires need catalic converters....

Answer 2

I personally believe that the Global Warming is apparent. Those who deny the fact that Global Warming is not caused by us, they should pay more attentions to science.

First of all, we do produce carbon dioxide by exhaling oxygens.

Second of all, the transportation that we ride do produce carbon dioxide from combustion engine.

Third, light bulb, copper wires, and electric train(maglav train) do produce carbon dioxide by heating tungsten and copper wire with oxygens.

Fourth, the garbage trash that we produce also undergoes into rottening process to produce carbon dioxide and methane.

Fifth,  volcano and natural hazardous fire also produce carbon dioxide, but nature has been balanced that out through photosynthesis process from trees to make energy from carbon dioxide. However, deforestation abated areas that are preserved with trees and land grass. So the balance between the production of carbon dioxide and the absorption of that has been deteriorated by us.

Sixith, the power plant uses burning fuel to generate electricity to equal out our demand on usages of air condition and electronics.

Last, a small amount of any green house gas can be a threat if the balance is destroyed. Small iron or lead concentration into our blood vessel can be harmful just as the concentration of greenhouse can do to the global warming.

The nature has certain limit of absorbing greenhouse gas to use it as energy. But excessive-production of greenhouse gas by us is destroying the balance.

If we don't take the responsiblity, this will only degenerate.

Answer 3

In the first place, the increase in atmospheric CO2 since 1800 is 37%, not 27%. In the second place, this increase is not associated with population increase, it is associated with fossil fuel use. In the third place, your math is flat-out wrong. The per-person contribution in 1750 was zero, because there was (virtually) zero fossil fuel used at that time. In 2004, per capita fossil fuel use averaged 1.23 tons of carbon per year.

Answer 5

First off, your logic and math are wrong.  For one thing the CO2 increase has been 37%, not 27% (from 280 ppm to 384 ppm).

I don't know where or how you get this 99.96% decline figure.    People contributed to 0% of atmospheric CO2 prior to the Industrial Revolution.  You can't decline from zero, unless you're trying to argue that we're taking CO2 out of the atmosphere even though levels are increasing.

You seem to be assuming that humans are responsible for all CO2 in the atmosphere ever, which is simply wrong.  That's my best guess as to how you got that bizarre number.

Anyway, to answer your question, we know from isotopic analysis that humans are responsible for essentially the entire 37% atmospheric CO2 increase.

And we know the increase in CO2 is causing global warming.

Answer 6

Most of that increase came in the last 50 years, as use of fossil fuels skyrocketed.  It's not how many people, it's what they're doing.

Scientists have proven that the increase in CO2 is due to burning fossil fuel, using "isotopic ratios."  Buried fossil fuels have lost all their carbon-14 from being shielded underground for so long.

Answer 7

Of course humans are responsible for increased CO2 and Global Warming.

Maybe you should narrow your time line to the more recent past. Why don't you begin your time line at about the time automobiles and the burning of fossil fuels became prolific. If you narrow your search to these recent times in human civilization, you'll see a direct correlation between humans and Global Warming.

Answer 8

only politicians and the hollywood left are in a hurry to reduce it. the intelligent ones see it as the hoax it really is.

Answer 9

increased co2, yes

gw, no

global politics.

Answer 10

yes human are responsible for polluting air and the cause of all problems are cars exhaustion and trashes everywhere.... we have to hurry up and reduce it because we don't want burnt skin over the summer which is highly dangerous now for kids to go outside in the beach and many other adults too, and because of the sun is hotter and the humid is making the temperature more active.... we have a chance of having cancer when being outside ... it's going to be at the end of the world when people will starve to death, and that IF the water is contaminated, we're not going to survive for long...

so thats why we are needing to hurry up and stop global warming or it WILL get worst and we are going to suffer...

that way we need all the SUPPORT  that we can to reduce any necessary pollution!

Answer 11

Sounds like you're arguing with yourself.  I hardly know who to root for.

Answer 12

if you believe that humans are not.

than there should be absolutely no increase in CO2  regardless of population, beacuse humans don't cause it.....

so what do you think about that?  in 1800 lets say there were 1,000 people  and now there are 10,000 people.  and the average c02 in the atmosphere was 3%  If humans dont cause any fluctuation, than shouldn't the atmospheric level of c02 STILL BE 3%????

yes, according to you, yes it should.  but it isn't, its because we burn more fossil fuels now. and have clear cut more land.  so yes, we are causing a rise in c02 in the atmosphere.

Answer 13

You can massage the facts any which way you like, but the vast majority of climate scientists endorse the concept of global climate change resulting from human impacts.  The vast majority of governments throughout the world are acting to address the calamity.

Students and faculty at some of our top universities have some of their best and their brightest tackling the problem.  Research is occurring on many fronts.

Denial isn't going to get you anywhere on this one.  Empowering yourself by becoming informed is your best bet toward becoming part of the solution.
