Can you find percentages of where/what the greatest sources of CO2 in the atmosphere are? The answer might surprise you.
For me, it would take a prominent politically-active singer/actress speaking out about global warming before I would take it seriously as an issue. It would help if this person was Jewish.
Why don't you just come out and start a "Global Warming Is Causing These Hurricanes" thread? Why beat around the Bush?
I'll believe it as soon as President Bush says it's true.
There isnt proof that CO2 in itself is a major reason behind global warming?
Are you serious??? Show me a link to this one, i promise you i'll read it.
I never said mankind was the sole reason for the increases, that again would be silly. But to think we're not a big contributor to it is silly too.
Why do humans think we are so powerless to change things like this?!
when you assume you make an ass outta u and me
if i ever said global warming is causing these hurricanes, it was either outta anger cuz i was worried my hometown would be destroyed, or i was joking
So then the increase of CO2 since we've been recording it, has been due to these surprising sources? Gee, I guess taking this back a while we can assume CO2 started to exist like only about 500K years ago
It's like....are there more or less cars than 100 years ago?
How many pounds of carbon in the air from one car? 1 gallon gas = 22 pounds co2
Are there more or less rainforest than there was 100 years ago? (rainforest being the most efficient areas in the world for converting CO2 to O2, Oceans are the highest contributor due to sheer size)
Are the trends we witnessing going to be reversed any time soon? No, in fact they'll only keep going...
Sorry this image is from a German website. I hope you can still get the gist of it.
Damn...those Germans are some old mofo's.
Yeah, but you need to see where the majority of CO2 comes from before you assume it's all the dirty, mean humans....instead of just making assumptions.
I'd never say that humans don't have any affect whatsoever...that just seems like common sense. But you keep talking about CO2 like it's 90% humans doing all of the dirty work.
Well, it is hot outside

Just how much of the "Greenhouse Effect" is caused by human activity?
It is about 0.28%, if water vapor is taken into account-- about 5.53%, if not.
This point is so crucial to the debate over global warming that how water vapor is or isn't factored into an analysis of Earth's greenhouse gases makes the difference between describing a significant human contribution to the greenhouse effect, or a negligible one.
Water vapor cons utes Earth's most significant greenhouse gas, accounting for about 95% of Earth's greenhouse effect (4). Interestingly, many "facts and figures' regarding global warming completely ignore the powerful effects of water vapor in the greenhouse system, carelessly (perhaps, deliberately) overstating human impacts as much as 20-fold.
Water vapor is 99.999% of natural origin. Other atmospheric greenhouse gases, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and miscellaneous other gases (CFC's, etc.), are also mostly of natural origin (except for the latter, which is mostly anthropogenic).
Human activites contribute slightly to greenhouse gas concentrations through farming, manufacturing, power generation, and transportation. However, these emissions are so dwarfed in comparison to emissions from natural sources we can do nothing about, that even the most costly efforts to limit human emissions would have a very small-- perhaps undetectable-- effect on global climate.

What are the sources of carbon dioxide?
Carbon Dioxide (or CO2) is created naturally by animals' breathing (respiration) and by the decay of plant and animal matter. These processes are natural sources of carbon dioxide in the atmosphere and account for about 38% of all CO2 emissions (Figure 1). Another large natural source of CO2 includes the oceans.
Carbon dioxide is also released by the burning of fossil fuels (coal, oil and gas) for power and electricity, and the production of cement. These are anthropogenic or man-made sources of carbon dioxide. Although man-made emissions of CO2 are significant, they are much smaller than natural emissions.
Another important man-made source of carbon dioxide is deforestation. Trees and plants take in carbon dioxide through the process of photosynthesis, and store it as carbon in their tissues and wood fibre. In many regions of the world, forests are being destroyed to clear land for development. This allows the large amount of carbon in the wood to be released into the atmosphere as carbon dioxide.

I'm guilty of contributing to man-made gasses.
yep, it sure is. I can remember running around barefooted and without a shirt on Christmas day when I was a kid. Just Texas I guess. It is hot here, one of the reason's I like it....
The planet has always gone thru cycles.. multiple ice ages...
multiple ice meltings.. multiple quakes.. storms .. waves.. asteroids.. etc..
Do we need to keep a focus on pollution and energy yes..
But the constant political harping.. one second it's the economy stupid the next it's pollution..
make up your liberal wiener mines you can't have a good economy without 18 wheelers ships trains and autos .. at least not quite yet without new power...
You see.. damned if you do. .damned if you don't..
What if we could say snap our fingers and transform every family on earth to middle class with 2 cars and a 3 bedroom house loaded with ..
We would like run out of gas in a day.. there are 2 billion people without power .. and billions more without cars..
There are happy people in the jungle that don't want Kerry's SUV.. they want people to off and leave them alone...
A hot plate of fried monkey brains on a rainy day in the rain forest may be richer than a day with kerry and his wife on there yacht.
Me too. I want to wear my cute jacket I just bought!
I would just like to walk outside and NOT have my mascara melt on my eyelashes.
Stars burn elements for fusion fuel.. they start with simple elements .. as the sun starts to eat and produce more advanced elements it can grow in size and do all kinds of wierd things. This may of been what really killed the dino's. The sun has a "fusion" shift that produces a burst of radiation off the charts.. cooking almost everything on earth...
Not saying it could happen again.. uh.. maybe.
And you have to go and ruin everyting, don't you. Dammit, you know WE made it happen. Now shut-up and go to your room.
This damn heat makes me break out.....then again so does breathing.
S y, you are one of the reasons I like ladies. Because you are ladies. Men are so boring. I think by the end of the week you will get your wish, well at least late in the evening......
