Global Warming will not destroy Earth, and should not be so quickly acted against.

Alright. I think, from seeing your argument, this debate will come down to if this is really a threat to worry about. I'm going to start with your statement about the Medieval Climate Optimum. I admit, I was a bit unspecific when I stated that. What I meant to say was, the last time there was a major increase in temperature. The other instances of warming you mentioned are just building up to where we are now. As you probably know, the Little Ice Age followed the Medieval Climate Optimum. And, although it may not be entirely documented, it is very likely this would have happened with or without humans. The earth just works like that. Take the Ice Age for example. After the Little Ice Age, there was a period of warmth, as to 'recover' from the cold times. The Earth isn't known to have experienced a major Ice Age other than THE Ice Age, so we can't find a pattern in that. But if we look at the Little Ice Age, we may still be recovering from the Ice Age millions of years ago. In response to your comment about the Winter being less harsh, the population increasing, etc, you have yet to prove they are untrue. You have yet to prove them untrue. You acknowledge the Medieval Climate Optimum happened, therefore there simply isn't a reason they would be untrue. Despite many of the myths, there isn't as much evidence that disasters will increase as you would think. Warming will not cause a significant increase in temperatures around the Equator. Only closer to the Poles. There will not be a significant increase in natural disasters, because most disasters will happen near the Equator, anyway. Would it not be true that, heat would cause evaporation? And evaporation would cause precipitation? And precipitation would combat droughts? On the topic of floods, man has time to prepare. There is a good chance it will be another, at the least, 50 years until we will know for a fact our cities are in danger of flooding. As naive as it sounds, I'm sure a large wall, much like the levees that are used to protect many hurricane-prone areas, could effectively protect our vulnerable cities from floods. Reports have shown that the ocean levels have increased at a steady rate for the past century or so. Every decade, another inch. Simple as that. There are no reports of any drastic rise in the sea levels since the Global Warming theory was released. Simple as that. It is true that the glaciers would begin to melt, but, although there has not been much evidence of this so far, I've done a bit of research on the subject. Heat would cause more precipitation. More precipitation would, scientifically speaking, add on to the glaciers. "The industrial revolution began in the 18th and 19th centuries...as I stated before climates started to rise around 1860." Climates have been rising and rising long before the 18th century. Chances are, it was hardly significant enough to document back then. CO2 is a minor factor in the entire global warming picture. All of these energy efficient cars and other environmentally-friendly solutions like that, I will admit they are great for the environment. But, there is little man can do to prevent Global Warming from happening. Simple as that. I eagerly await your response.
