Today, everyone is well aware of the serious effects of Global warming. We are being urged to take action by using more energy saving appliances and generally be more vigilant in helping reduce the emissions of greenhouse gases into our damages atmosphere.

While we acknowledge the damage mankind has done and the problems we have created for ourselves it is interesting to note that there are also many natural causes of global warming and even if we did not exist on the planet natural causes of global warming would still exist.

We all know about greenhouse gasses such as carbon dioxide and methane. These gases, along with water vapor have a very important role to play as without these gases heat that keeps our earth warm would escape our atmosphere into space, leading to a very cold earth indeed.

The process of prohibiting the heat from escaping is a very natural process cause by naturally occurring gases. There are also natural variations in temperature caused by variations in the earth's orbit, variations in the sun's output, sulphur dioxide emitted by volcanoes (sulphur dioxide has a cooling effect). Sunspots are also known to be a contributing factor and more research is taking place to investigate the effects of these causes as compared to man-made causes.

Interestingly, research shows that the earth was in fact warmer during the Middle Ages. A team from Harvard University team examined the findings of temperature proxies including ice cores, tree rings, and historical documents to get an estimated temperature range. Their research shows during the Middle Ages there was a “warm “period between the ninth and fourteenth centuries with temperatures far warmer than we experience today.

They have also found strong evidence of a mini Ice Age around 1300, at which time the world dramatically cooled. It is only since 1900; the world has begun to warm up, but has not yet reached the high temperatures of the Middle Ages.

Yet, other academics dispute this and claim that studies of trunks of ice cores and ancient tree trunks from both Antarctica and Greenland show that temperatures have indeed been warmer since 1980. And so the debate continues and while the different ideas and theories are examined and argued, we know for sure that natural causes of global warming do exist along with the man-made causes.

If we do not change our ways, imagine the impact of a rise in temperature from natural causes combined with a rise in temperature from man-made causes and we have a recipe for disaster.

One of the problems is that natural causes have always been there and will continue, but humans have been polluting the planet for a long time and we must understand that it will take a considerable amount of time before we see any affect from our change of habits.
