Question

Someone says to you, "Here it is the Fourth of July and I'm still having to wear a sweater! It's so cold! That climate change stuff is bunk!" How do you answer them using science, evidence and reason?

Answer 1

The conditions that are mentioned in statement is about the weather of that particular place which is basically a short term conditions of atmosphere that exists in a particular area and this cannot be correlated with the climate of that particular area which refers to the long term conditions of atmosphere. Even the concept of climate change derived by the use of conventional fossil fuels is the major issue that the world is facing right now as the major issue with normal fossil fuels are that they produce a lot of green house gases which are responsible for the greenhouse effect which refers to the conditions when the earth’s atmosphere gets warmed up by the sun’s radiation becaue of the gases which radiates energy very affective (these gases are known as green house gases example: water vapours, carbon dioxide, methane etc.). The greenhouse effect is important for supporting the life and various life processes as in the absence of greenhouse effect the temperature on earth would become far less than the sustainable temperature. But enhanced greenhouse effect is responsible for the global warming of earth and this phenomenon of global warming is having many negative effects. This phenomenon of global warming Is taking place the rate with which the carbon dioxide emissions is increasing (exponentially) which is a green house gas and thus will increase the temperature of earth cannot be nullified by any natural feedback system and this increase in the temperature is causing melting of ice caps and is therefore responsible for the increase in the global water level. This can be illustrated by using the “Hockey stick curve” which shows that during the last 2,000 years, the last century shown an exponential increase in the global temperature and this trend will follow in the coming years if we don’t look about our carbon dioxide emissions which is causing an increase in global temperature by the phenomenon of global warming. This curve is attached below:
