I'm not offended on the double post thing; thanks for calling me on it. (I'm still learning the ins and outs of this site)
Also, I don't quite understand what you meant by only mentioning what I looked into and not what I discovered. Could you clarify?
I probably shouldn't have mentioned the Nat. Geo. link as much as I did, because you're right, it isn't concrete evidence. I thought it would be an interesting graphic for people to look at. However, you said something earlier about scientists forging data, and I think that is highly unlikely. Even if someone had the motive to do so, hundreds of people all over the world are looking at this issue, and if it is completely made up, you'd think the majority of them would say something.
One of the hard things about arguing over this issue is that it can be really tempting to bring in current examples of possible phenomena. I'm pretty sure that this year is an El Niño year, so that might have an effect on what is happening in California. However, global temperatures have risen 1.5 degrees Fahrenheit (on average) around the world (I might be wrong on the exact number, but the gist is the same). That's too big to be a local trend. I haven't heard the solar flare hypothesis, but it doesn't make a ton of sense. Although I've read about the electromagnetic effect of a flare on the earth, I don't understand why that would translate to a rise in temp. (Does it release more UV radiation perhaps?). Also, you'd think that if solar flares were linked to the warming, there would be a trend in the data, or a dramatic change in temp before and after a flare. (I'd love to hear more about that idea)
About the volcanoes, that is true, but they also put sulfur dioxide into the stratosphere, which reflects some of the light back into space. We may not be able to control volcanoes, but we can control cars. I'm not quite sure how many cars are equal to one St. Helens size blast, but I have a feeling it is probably within the number of cars used around the world.
It was a bit sensationalist of me to do the whole "We're all going to die" thing, wasn't it. Not my best argument.
Although you may be right about our current growth rate, the carbon rise is not linear. Instead, the amount of carbon dioxide in the atmosphere would rise exponentially, along with the number of people on earth.
As far as the plankton thing, I have no idea. It's been so long since I've studied marine biology. 2nd grade at least.
The animals adapting to their surroundings I disagree with, because it would be hard for generations to adapt that quickly. If the animal that another depends on for food dies out, would it be able to change food sources before it died?
You could call it natural selection, I suppose, but you could look at a lot of things that way. In WARP book one (the best example I can think of right now), was Riley at fault for holding the dagger that killed Orange's dad? Or was the guy who moved Riley's hand at fault? Most people would say the person who moved his hand, which, if you go back to the issue, would be the human race. (Riley would be the principal of natural selection.)
Trees do use CO2 in the process of photosynthesis, but they also need water and land to do that. If the soil is to hot to hold a reasonable amount of water, the tree is dead. If people are using the land for farming or building, the tree doesn't have that space. Another thing to consider is the detrimental effect of acid rain on the trees.
Sorry my response to BlueAlice was a bit confusing; I meant it to be the opposite. What I meant is that because of a rise in temp, more water will evaporate off of bodies of water, like the oceans. That will heighten the effects of weather patterns El Niño and La Niña, which are bad enough as it is. I'm not saying the world will die in ice and fire, I'm just implying that not only will heat inflicted natural disasters get worse, but natural disasters related to water (unlikely snow, but that's possible) like hurricanes and floods are likely to get worse as well.
Keep debating, this is fun!
(Also, I think I'm learning the art of long posts. Rocket will be proud!)
