Re: Global Warming Fact or Fiction?
Ok guys. The increase in CO2 has been shown to be linked with the increase in oil consumption. This is how it works.
Plants take up CO2 to grow. That CO2 is stored in the plant material. When a tree is burnt, the CO2 that was in that tree is released back into the atmosphere. When that tree decays, the CO2 is then released into the atmosphere. Everything sounds good so far right. Plants take in CO2 then release it. It's a perfect balance. So what is the problem?
Where does oil come from?
Oil comes from plant material that never was burnt up or decayed. It's CO2 is trapped. Now compound millions of years of plants that are trapped. The amount of CO2 trapped adds up pretty quickly.
We now use the oil in a relatively short period of time (humans have not been around that long (compared to the earth) and we have been using oil for an even shorter period of time). We are releasing millions of years worth of CO2 in a short period of time. This is the problem.
In reality, it might not even be a problem. Increasing the temperature will make some changes. We will surely lose a lot of dry land from melting glaciers in the process. Maybe life will be better with higher temperatures. We don't know for sure. It also depends on your viewpoint. Maybe we'll discover some new technology that will be able to reabsorb the CO2 somehow or cool the earth like an air conditioner. Since we don't have those abilities yet, we try do the best we can with what we know.
Most people like the earth the way it is. Most do not want change. The earth will, most likely, survive but we may not. We are not as adaptable as the earth is. We may survive, but maybe not all of us. We could be in store for some serious changes. Unfortuanely, we have not been able to accurately model all of the changes that will occur with the rising CO2 yet. There are just too many variables.
Did you know that just changing the speed of decay of leaves from 12 years to 9 years will change the composition of the plants that live in that area? It has to do with the speed at which different nutrients become available from the decaying leave. Some plants will really need a certain nutrient while others don't need that one as much. The lack of the needed nutrient will let the plants that don't need it take over. It will then change the animals that can also inhabit that area.
Everything is built on a delicate balance. One small change somewhere can make drastic changes almost everywhere in that environment.
Science is all about learning everything about how something works and trying to exploit that knowledge for our own advantage and well being.
The scenario in the movie "The Day After Tomorrow" is scientifically sound. I couldn't believe it when I learned that, but it is. The ocean has a very complex balance as well between the deep water and the surface water. There is a point in temperature that could tip the balance and we could go into a rapid freeze. It actually already happened not too long ago. We have evidence of this. It gets really crazy when you get into the science.
The consensus of the scientific world has no doubt that we are causing the increase in CO2 by using oil which consequently increases the temperature of the planet. The evidence is just too overwhelming. It also has a great many other implications as well. The temperature change is just one of the easiest to wrap your brain around.
FYI: I have a BS in Ecology, Evolution and Behavior
oh yeah and the BS doesn't stand for Bull Shxx lol
