Did January Seem WARM To You?


Did January Seem Warm To You?

The NOAA is the National Oceanic and Atmospheric Administration

The “Goldilocks Effect” refers to three plants, Earth, Venus, and Mars. It is believed that Earth is “just right”, Venus is “too hot”, and Mars is “too cold”, just like in Goldilocks. Earth holds just the right gases, in just the right amounts to warm the earth to temperatures that are suitable to mankind. Earth’s ability to retain a certain amount of gas to warm the earth is what we call the greenhouse effect. This difference in temperature between the three planets is a result of the belief that each planet either has too much or too little greenhouse effect to support a sustainable life. The following is a clear explanation, which is taken directly from the website of the University Corporation for Atmospheric Research.

Mars and Venus have essentially the same types and percentages of gases in their atmosphere. However, they have very different atmospheric densities.
Venus has an extremely dense atmosphere, so the concentration of is responsible for a "runaway" greenhouse effect and a very high surface temperature. 

Mars has almost no atmosphere; therefore the amount of is not sufficient to supply a warming effect and the surface temperatures of Mars are very low.

Mars is much further away from the Sun than is Venus.

As for my own opinion global warming, I do believe that it is a result, perhaps not directly or mainly, but I do believe that it is a result of greenhouse gas emissions, however I am not saying that it is a fact. When it comes to the issue of global warming, I feel like the more I learn, the less I know. There are many theories that all support different causes of global warming, but I still stand strongly behind the GHG emission cause. Perhaps it is a bias, but I have learned much through classes in school, as well as watching Al Gore’s An Inconvenient Truth (as well as reading his book), that it just seems to make perfect sense. The science that backs up global warming due to GHG emissions is overwhelming, as well as the effects that can be seen in everyday life already. In addition, it is quite obvious that global warming is a result of GHG emissions, and can be seen through immense support of professionals.
