Is the Earth warmer now than it was a hundred years ago? The answer is yes. However the question of whether man is responsible is very doubtful. Let's explore why this is the truth.

The sun is the source of all heat on Earth. The sun goes through cycles. Some of these cycles we know about, but we are discovering others and many may be cycles that take so long we may never learn about them.

We know that during abnormally low sunspot activity (from the aspect of human lifetimes), this world cools down. There is little doubt about this and it has been well proven. For instance, during the 'little ice age', sunspots were absent for over 70 years. Corresponding to this time, the average global temperature was several degrees colder than it is now. Temperatures warmed up after the sunspots returned.

This is only a single cycle, and we have no idea why sunspots affect climate, yet we know that they do. Consider how many cycles we don't know about, or are just beginning to suspect.

It is also important to think about this: Temperatures globally were much higher than they are today, 1500 years ago, and 2000 years ago. All of the currently touted culprits for global warming caused by man didn't exist back then.

The fact is that through almost all of four billion years, the earth has been so warm that the ice caps didn't exist and couldn't have existed. Ice caps have only existed for less than one percent of the life of the planet.

Why is this important? Well, because the proponents of the idea of man caused global warming cite as proof the melting ice packs in the northern hemisphere. The problem is that they have been melting in starts and stops for the last 11,000 years, since the end of the last ice age. A question is often asked as to whether man has increased the speed this is happening. The data shows that there is absolutely no way to tell. We don't have the knowledge or data to figure that one out. This is the reason that well over 95% of scientists haven't weighed in on the topic.

The truth is that we have more recently uncovered proof that the earth may be cooling down. Again, though, we don't know why. The storms of recent years around the globe are more in tune with global cooling than with global warming. Record low temperatures have been recorded all over the globe in the past two years, for instance.

Consider this as well: All the biggest reasons the very few scientists use to point to man as the culprit are cause of global warming are in far greater degree suppositions than man is capable of. Carbon dioxide, methane, and other greenhouse gases are produced naturally in far greater quantity than all the people have the ability to produce.

In fact, a single moderate volcanic eruption produces more of these gases than man produces in a year, and at any given time, 11 to 13 volcanoes is erupting. Man would have to produce more than 15 times more greenhouse gases to even keep up.

What is more, if ice packs melt and the temperatures raise, the ocean becomes more able to capture carbon and other greenhouse gases than it was before the increase in temperature. As previously stated, it is a self-sustaining system. If temperatures do rise, the earth finds a way to bring them down again.

We may be in a current cycle of increase of global temperatures, and this has been proven in the last century to be a few tenths of a degree, but it is only a matter of time before the temperature goes back down. Man can't stop it, he isn't to blame, and only arrogance causes him to think that this is incorrect and that he can cause or correct the temperature fluctuations of the planet. The data is there for anyone to see.
