Peterkin, I know you ain't talking to me like I don't know stuff... Here's a prescient jam:

RE: Man Made Global Warming
I've been "officially atheist" since October, but I'm pretty "religious" about it - in that an atheist knows the right thing to do. All of these posts I write are becoming "additional clarity" for a future rendition of Chaotic Determinism - merely a philosophy, but a way of thinking where thinking of Gaia becomes second nature.

The sun flares, cosmic radiation, volcano eruptions, normal climate changes, there can be all sorts of non-human reasons. Still waiting for something that will convince me otherwise. This is the absolute fact of the matter right here. You can argue up and down all day about how much effect humans are having, but no one, but no one, would argue we are not having an effect. And even if you argued that climate change and global warming was a completely natural phenomenon, that is not an argument to continue on with the status quo. Lets say you live by a flood plain and every year the floods washed away your home. Do you keep rebuilding your home the same way, or do you try to build it a few feet off the ground and above the flood level? Just because its a natural event does not justify inaction. The only one who would advocate inaction is a religious nut, who thinks god will fix it, or a bad economist, who thinks green jobs are a myth. |

Looking at it apparently it seems to show a cyclic event going back 650,000 years of rising....and fallin.....rising.....and falling of carbon concentrations.....with us currently in a rising state. These could be caused by a huge factor of events other than man made causes..(as the graph proves)...handily enough listed here from the very same website you previously linked. http://www.epa.gov/climatechange/science/pastcc.html So when scientists can factor in such things as...Changes in the Earth's orbit, Changes in the sun's intensity, Volcanic eruptions (Aerosol and Carbon dioxide emissions) and more which TBH I cant be bothered to list.......... then COMMON SENSE would seem to prevail in my eyes. Ill be straight with you and say just posting one graph and saying that is common sense is just pathetic.........please do some more research. Also like I mentioned before it isnt just our planet that is going through changes.....it would appear that all of the planets in the solar system seem to be going through the same things that we are now.......I mention for further research Saturns moon Titan as one of many. I feel so much, and yet I feel nothing. I am a rock, I am the sky, the birds and the trees and everything beyond. I am the wind, in the fields in which I roar. I am the water, in which I drown. |

RE: Man Made Global Warming
I am going to throw my 2 cents back into this debate, as it appears to be getting rather heated (no pun intended, unless it was funny and then I did it on purpose).
Let's start off with that graph. We are certainly in a period of naturally elevated CO2 levels with our current concentration somewhere around 380 ppm. If (big if) we take a look at the overall trend in the data and match one of the previous set of wiggles to our current wiggle, then our CO2 concentrations should be on the decrease by now. This would imply that if there is a direct correlation with CO2 concentrations and temperature, that we should be entering a new ice age, but we are certainly not. SO, here is the issue, the rate. As far as we can tell, the rate at which CO2 is being released into the atmosphere today is much higher than anything we are seeing in this graph from the past ~600,000 years. That is a big problem if it is true. Thought experiment: Let's start off with a pitcher of room temperature water and some sugar. If I slowly add in the sugar while mixing, it will dissolve easily. But, if I dump in the sugar too quickly, it will sink to the bottom with very little dissolving in, at first. That is what is happening now, we think. The rate at which CO2 is being released is (potentially) to fast for the system to equilibrate itself. This would lead to an increased amount of CO2 in the atmosphere which is the global warming issue. In turn, the CO2 from the atmosphere will begin to equilibrate with the oceans but this too is happening too quickly and is resulting in ocean acidification (carbonic acid). This all supported by deeper time data as well. At points in Earth's history we have evidence (mostly C13/C12 data) that suggests CO2 concentrations that were 10x levels today (or more). Temperatures weren't drastically different during these periods and they certainly were not 10x higher. Even an increase in CO2 that happens slowly enough can be dealt with naturally. The oceans have a method of buffering themselves as long as CO2 is coming in at a slow enough rate. This ocean equilibration coupled with continental weathering reduces the net change in temperature. So, the issue is not the absolute amount of CO2, but the rate at which it is being released. If we look back at events like the end-Permian mass extinction, we may get an idea for what can happen when CO2 is released too quickly. At the Permo-Triassic boundary there was a massive release of lava from the Siberian traps. This released massive amount of CO2 over a very narrow window of time and the result was the largest mass extinction in Earth's history (96% of marine species went extinct). What is happening now is not necessarily equal to that in amount or magnitude, but it is similar in its rate. And (as I have tried to demonstrate) that is the issue. Are humans the sole cause? Almost certainly no. But, are we a major contributor? That is much more likely. |
