Global politics names both the discipline that studies the political and economical patterns of the world and the field that is being studied. At the centre of that field are the different processes of political globalization in relation to questions of social power.

The discipline studies the relationships between cities, nation-states, shell-states, multinational corporations, non-governmental organizations and international organizations. Current areas of discussion include national and ethnic conflict regulation, democracy and the politics of national self-determination, globalization and its relationship to democracy, conflict and peace studies, comparative politics, political economy, and the international political economy of the environment. One important area of global politics is contestation in the global political sphere over legitimacy.

It can be argued that global politics should be distinguished from the field of international politics, which seeks to understand political relations between nation-states, and thus has a narrower scope. Similarly, international relations, which seeks to understand general economic and political relations between nation-states, is a narrower field than global politics.
global issue describes any global social, economic, political or environmental problem that has already arisen or can arise from global change or globalization, e.g. overpopulation, or water scarcity.

In their book "Global Issues", Hite and Seitz emphasize that global issues are qualitatively different from international affairs and that the former arise from growing international interdependencies which makes the issues themselves interdependent.
Global Issues: Ozone Depletion, Global Warming and Acid Rain
[attachment=849]
Introduction

Air pollution is exerting increasing impact on the environment. Humans have been altering the chemistry of the atmosphere on a global scale. These changes may:
Modify the global climate
Threaten the health of human beings
Create many environmental problems such as
Acid rain
Depletion of ozone layer
Global warming
Seriously upset the global ecosystem

What is ozone depletion?

Ozone is a highly reactive gas comprising triatomic oxygen
Ozone layer in the stratosphere protects the Earth s surface from UV light
Ozone depletion refers to a lowered concentration of ozone in the upper atmosphere
Holes are formed
More UV radiation is reaching the Earth s surface .

What are the effects of ozone depletion?

UV radiation is absorbed by DNA and modifies them, affecting the expression of genetic information
A higher incidence of skin cancer,lung diseases and cataract
Reduce the yields of crops
Disruption of the ecological balance in the ocean
A higher incidence of photochemical smog

What is global warming?

Global warming refers to the gradual increase in the average temperature in the atmosphere
Increase in concentration of greenhouse gases in the atmosphere
The heat loss from the Earth to the Space is slowed down
An enhancement of the greenhouse effect leads to global warming
Greenhouse gases include carbon dioxide, chlorofluorocarbons, methane, nitrous oxides, ozone, water vapour, etc
