Forecasting the End: Nothing lasts forever

Last night when I was watching TV I happened to turn to weather channel and they had this episode called “Forecasting the end: Nothing last forever”. The episode discusses about the changes that happens into our solar system that may contribute to the end of humanity. The episode shows indication that our earth is slightly moving off the orbit due to man made changes. The effects of global warming play a huge in the earth’s displacement. If the earth completely displaced from its orbit that means we are moving away from the sun. As we know life on earth is supported by being at a constant distance from the sun. Moving away from the sun means that’s the beginning of the end of life on earth. Temperatures will go down and every living organism will freeze to death.

After watching that episode I become more interested on researching about other species extinctions that have previously happened. Over 98% of documented species are now extinct. Dinosaurs after living 160 million years they got extinct. There have been five life extinctions from when life started on earth. This makes me wonder is this just part of nature that species occupy earth for just period of time and then get extinct or species are the ones casing that extinction?. May be our way of extinction is through self-destruction where global warming and overpopulation depletes earth’s natural resources and that becomes the beginning of the end.

  1. I haven’t seen that specific show, but I do remember discussing this same climate-change concept in my astronomy class.

    If I remember correctly, scientists have discovered that our planet’s axis is always moving. It shifts like .2 degrees a year, or something. They don’t know exactly how the Earth’s climate is going to change, but they are predicting another ice age several thousand years down the road.

    I think this idea is extremely interesting. Could our climate really be in a larger cycle than scientists even realize?

  2. This is interesting; however, the reason we don’t hear more about it is probably not that scientists don’t realize it (orbital oscillation is mentioned in the first chapter of Emanuel’s book), but that the effect is still thousands of years off. At this point I suspect the general feeling among many climate scientists is, “Let’s see if we can make it for another century or three first! Then maybe we can start preparing for the next ice age.”
