What are your opinions on global warming? Do you believe that it is happening right now!.. Or do you believe it's just a load of shit?
Sure it might just be because of a cycle of increasing and decreasing temperatures on Earth, but note how the recorded rise of temperatures in this particular cycle are far more above the other recorded temperatures of other times in the past where the cycle was at it's highest peak.
We have an abnormal amount of CO2 in the atmosphere. Now if there was a good way of slowing it, stopping it, and then reversing it back to a natural state. Heck, I think we'll be lucky if we'd get to stopping it.
