Abstract: Background: In this article we develop a global warming indicator model under fuzzy
system. It is the light of the sun that environmental pollution is responsible for the cause and imme-
diate effect of global warming. Limited amount of oxygen in the air, continuous decrease of fresh
water volume, more especially the amount of drinking water and the rise of temperature of the globe
are the major symptoms (variants) of global warming. Thus, to capture the facts we need to develop
a mathematical model which has not yet been developed by the earlier researchers.
Introduction: An efficient literature survey has been done over the three major parameters of the
environment namely oxygen, fresh water and surface temperature exclusively. In fact we have ac-
cumulated 150 years-data structure of these major components and have analyzed them under fuzzy
system.
Methods: First of all, we gave few definitions on fuzzy set. Utilizing the data set we have construct-
ed appropriate membership functions of the three major components of the environment. Then ap-
plying goal programming problem, we have constructed a fuzzy global warming indicator (GWI)
model subject to some goal constraints with respective priority vectors (Scenario 1 and Scenario 2).
An extension has also been included for multi-valued goal programming problem and numerical
illustrations have been done with the help of LINGO software.
Results: Numerical study reveals that the GWI takes maximum and minimum values in a decreasing
manner as time increases. It is seen that for scenario 1, the global environmental system will attain
its stability after 30 years by degrading 31% of GWI with respect to present base line. For scenario
2, after the same time the global environmental system will attain its stability quite slowly by de-
grading 28% of GWI with respect to present base line.
Conclusion: Here we have studied a mathematical model of global warming first time using fuzzy
system. No other mathematical models have been found existing in the literature. Thus, the basic
novelty lies in a robust decision-making approach which showed the expected time of extinction of
major species in this world. However, extensive study on data analytics over major environmental
components can tell the stability of the global warming indicator and hence the future fate of the
globe also.

1. INTRODUCTION
1.1. Background
Most researchers address global warming by considering
numerous parameters associated with Physics and Chemistry
disciplines. But in this article, we are going to study those
parameters which have a significant responsibility towards
global warming. These parameters are associated with the
amount of oxygen in the worldwide atmosphere, water scar-
city and the hike of global average surface (atmospheric)

temperature. Now the existing knowledge over global warm-
ing can be viewed under three major components as follows.
A recent study reveals that global average temperature is
currently increasing by 0.2 degree Celsius per decade. How-
ever, it is estimated that Earth’s average temperature is in-
creased by 1 degree Celsius (approx.) from the pre-industrial
period (between 1850 and 1900) due to human activities
such as fossil fuel burning, deforestation, excessive use of
ground water etc. These activities are solely responsible for
heat trapping greenhouse gases in the atmosphere of the
Earth. The most dangerous effect of global warming is the
challenge of surviving the human race and some other ani-
mal species due to the degradation of oxygen, scarcity of
drinking water, increased sea level and hike of air tempera-
