Global Warming Is Today, Not Tomorrow
“Never have we so hurt and mistreated our common home as we have in the last 200 years”

Global warming has been a subject of great debate all across the world. It has turned out to be a sensitive topic for many people. Twenty years ago climate scientists were discussing whether if the earth was cooling down or warming up. Today, a vast majority of those scientists believe global warming is real and that it’s having a dangerous impact on the planet we inhabit. What caused those scientists to change their minds, what evidence did they uncover, and what do they determine about ours planet 's future?

To explain how global warming is created first I need to go through a couple steps of easy physics. First, if we have an object with the given temperature “T” then the amount of energy flowing into and out of the object determines whether the temperature inside the object changes. So if more energy is flowing in than out, then the object 's temperature increases. Secondly, any object at temperature “T” radiates energy out at a rate proportional to the fourth power of its temperature. What that basically means is that a really hot object radiates a lot more than a eold object. So if we take earth as our object which gets all its energy from the sun and is hot due to since the sun 's temperature is so hot it emits a huge amount of energy. Some of it gets captured by our earth, either as visible light or as thermal radiation. Now, the earth…
