The problem with what one preceives is it can be affect by a preconceived idea. For example, you want to believe that the reason for climate change is CO2 produced by man so you have a proconceived view or the world. In that preconceived view you cannot see that CO2 levels increased after the temperature did. Later they discovered the reason was permafrost was releasing that and methane which had been trapped. Which means that it had to be there when the earth in that are froze and was trapped.<quoted text>
First, it is not my word, but that of scientists who have studied and measured as carefully as possible. We may not know exactly how much radiation would kill you but we do know that if the level exceeds a certain amount that your life is going to be compromised.
Science is never exact. It is simply what we perceive from observations and logic. However, we must live in the universe as we do perceive it. For example, we expect a mass to remain at rest or move at a uniform velocity unless it is acted upon by an outside force.
We also expect the ocean to continue to become more acidic as we increase the level of CO2 in the atmosphere by burning fossil fuels. We also expect the Earth to warm as the CO2 increases. To do otherwise would be in direct opposition of our understandings of universal perceptions. To not accept this would be to disregard all human understandings of our existence and a total disregard for science and Western philosophy. If that were to be so, what would be its replacement?
Often, what is preceived is discovered to be wrong. At one time it was preceived that the universe rotated around the earth and that the earth was flat. Later it was discovered that what was preceived was wrong. That the earth was a sphere and that it was only a fragment of the universe. The interesting thing is how those early learned men clinged to this idea dispite the proof that they were wrong the way you cling to the idea that man is the cause of climate change. In both cases, the need to believe that man was important to the scheme of things is central. The need to see man in complete control and master of the universe. To see man as the center of existance.
