Life on Earth could be affected if the atmosphere did NOT contain greenhouse gases in the following way: "There would likely not be life on Earth because its surface would be much colder and Earth's water would be frozen."
Scientists agree that this is basically the importance of greenhouse gases on the atmosphere of planet earth. Without these gases, the surface of the earth would have an average temperature of minus 18 centigrades. Many life forms as we know them could not survive under this hairs climate condition. Furthermore, most of the surface of the earth would be covered on ice.
If Ken does not account for variables such as age that could also influence one's ability to recall these events, age could be considered a "confounding variable".
A confounding variable is an outside impact that progressions the impact of a dependent and independent variable. This incidental impact is utilized to impact the result of a experimental plan. Basically, a confounding variable is an additional variable went into the condition that was not represented. confounding variables can demolish an examination and deliver futile outcomes.
