Atmospheric CO2 levels rising By jen and karle

Scientists say that CO2 have been rising at an alarming rate, and probability is that humans are the cause.

There are many lines of evidence which clearly show that the atmospheric CO2 increase is caused by humans. The clearest of these is simple accounting - humans are emitting CO2 at a rate twice as fast as the atmospheric increase (natural sinks are absorbing the other half). There is no question whatsoever that the CO2 increase is human-caused. This is settled science.

What is CO2?

Carbon dioxide is a naturally occurring substance composed of one atom of carbon (C) and two atoms of oxygen (O2). Its chemical formula is CO2. CO2 is gas under normal conditions.
