This is the question. One of the most acute problems facing human society is determining the impact of human activity on the environment, with regard to the overall increase in temperature over the past century. As the atmosphere heats up, actions must be taken promptly in order to avoid or to prolong the devastating effects of global warming. Ice core data showing CO 2 levels over this millennium. However, measures are being taken in order to reduce the emission of greenhouse gases into the atmosphere.
Greenhouse gases are any gases that absorb infrared radiation in the atmosphere.
When in high concentration in the atmosphere, they produce the greenhouse effect, by not allowing the infrared radiation from the surface of the earth to escape in outer atmosphere. It measures atmospheric buildup of carbon dioxide. The amount drops each summer as plants suck up more carbon dioxide but then increases once leaves are shed each Fall. The implementation of this agreement is to take place between 2008-2012. The debate is whether such an extended implementation time is needed, considering the rapid increase in temperature that we are facing.
