Time Recursion

There was a lot of talking about climate and ecological changes in the past few years. Some were predicting catastrophes of enormous dimensions, others said it was pure nonsense. Some of them said it was our fault that the climate is going crazy, and again there were others that simply called it a natural cycle, which occurs every few thousand years.

Which of them is right?

First of all, we have to find out in which way people contribute to such changes. The most obvious is the constantly increasing percentage of Carbon Dioxide in our atmosphere. Scientists have analysed the amounts of Carbon Dioxide present in the ice in Antarctica and composed a chart showing the changes of its concentration through the past 400.000 years. The last part of the graph, showing only the last two hundred years is quite alarming. The concentration of this gas mixture is almost twice as high as anytime before. Now why would this be so alarming, apart from the number being so unnaturally big? The reason why are the ecologists so upset about this information, is because Carbon Dioxide forms a sort of “cover” over the Earth, allowing it to keep the air in the atmosphere more warm for a longer time. This way, the Earth is not able to cool down, which results in increased temperatures all over the world. And why is this bad, since we still have pretty cold winters?

The answer is simple. The Earth’s climate works as a whole, and responds to each and every change accordingly. Even slight changes in temperatures in only one place, for example on Antarctica, can cause changes of large proportions. If we return back to Antarctica, we can quickly find out, that because of increased temperatures, the ice is melting faster, and longer, which results in heavier cold sea currents, that are slowly changing the climate not only locally, but globally.

Now, if we take a look back at the chart showing the levels of Carbon Dioxide in the air, we can see that there were changes in the past already. They weren’t so radical as in the past century, but still quite big. And how were they possible, if there was no industry at that time? We all know that trees consume the Carbon Dioxide and as a result produce Oxygen. The peaks in the chart show the Ice ages, because at that time there wasn’t much greenery on Earth, since the majority of its surface was frozen. That is why the amounts of Carbon Dioxide were so high. But because of its high concentration, the ice melted more quickly allowing more trees to grow and reducing the concentration of Carbon Dioxide in the atmosphere. And so it went on and on.

There is another interesting thing that is shown on this chart. Even before the drastic increases of human produced Carbon Dioxide, we entered the timeline in which another Ice age should begin. And since we’re speeding this process with our emissions, there may be only a few decades more before it happens instead of a few hundred years.
