Question

What is the impact of positive feedback effects on global climate change?

Answer 1

Global climate change feedback is very essential aspect in understanding global warming . Feedback processes either amplify or diminish the effects of climatic changes and can predict conditions of climate in future . Feedback can be defined as the process in which changing one quantity changes another quantity , and the change in the second quantity in turn changes the first . Positive feedback amplifies the change in the first quantity while negative feedback reduces it . It is a cause and effect system . As for example : trees are believed to be diminishing in number as a result of climatic changes . This is a positive feedback effect . The second cause amplifies the first ( tree deaths ) .
