How Real Is Global Warming
At the very worst, scientists will tell us that global warming is so serious that there will be more hurricanes and that death will occur since there will be less food available on earth. At the same time, others believe and will state that global warming is a farce and that the earth will simply be warmer at some times and cooler at others. A third option offered to us is that perhaps the earth is warming up but since the atmosphere has not changed we only need to make a few small changes to save ourselves and the earth from destruction. Considering all these choices, it is beneficial for us to learn what causes global warming in the first place so lets assume that it is present and that it is actually a threat.
