One of the most fundamental pieces to Climate Change is that since the Industrial Revolution in the 1800s, concentrations of greenhouse gases (ozone, carbon dioxide, methane, water vapor, and nitrous oxide) have increased rapidly. If these gases are vital to Earth and life on Earth (as we know it today) would cease to exist without them, then why are scientists alarming the public that their rapidly increasing concentrations are a bad thing? Why the freaking out? Remember to form your thoughts and opinions well and back them up with facts.
