The answer for the above question is carbon dioxide.
Climate change is caused by various factors which includes greenhouse effect and global warming. Green house gases are responsible for warming, and humans emit them in a variety of ways. The most common being from the combustion of fuels in cars, factories and electricity production. The gas responsible for the most global warming is carbon dioxide, other contributors include methane, nitrous oxide from fertilizers among others
        
             
        
        
        
antagonism
When two hormones cancel each other out or have opposite effects it is called antagonism.
<h3>What is an example of antagonism?</h3>
- Traditional examples of antagonistic hormones include insulin and glucagon. 
- In contrast to glucagon, which stimulates glycogenolysis, or the conversion of glycogen to glucose, insulin stimulates glycogenesis, or the conversion of glucose to glycogen.
<h3>What does the term "antagonistic hormones" mean?</h3>
- Antagonistic hormones are those that work to bring body circumstances back from extremes to within acceptable bounds. 
- An illustration of how the endocrine system maintains homeostasis through the action of antagonistic hormones is the regulation of blood glucose concentration (by negative feedback).
<h3>How do antagonists to hormones function?</h3>
- Infertility, endometriosis, and uterine fibroids are just a few of the diseases that gonadotropin releasing hormone (GnRH) antagonists are used to treat in women. 
- GnRH is a hormone released by the hypothalamus that is the target of GnRH antagonists, which stop it from functioning.
