Protecting the Earth's atmosphere has become a concern on the agenda of all mankind, regardless of how one state or another is involved in resolving or worsening of this serious problem. States are facing global warming, generating a triple dilemma. First, there is the dilemma of short-term and predictable costs to winning long-term and less predictable benefits. The second refers to some specific segments, such as oil companies and industrial workers bearing the costs, while most of the benefits are distributed in domestic and world society internaţional. The third dilemma concerns the collective goods between states, ie the benefits are shared globally and the costs to be borne by each state. The international system must face both the conflicts, whose number is increasing, and the complexity of the global management. As demands on the environment continues to grow, this problem grows and the two reasons which contribute to this pressure are: economic development and a greater number of people. Pollution as a global issue is the prerogative of our century, especially in the last thirty years when the population of the planet has greatly increased (from 5 to 7 billion) and the environment has been damaged by pollution, erosion and other phenomena due to the willingly or unwillingly actions of mankind. Compared to 400 years ago, as a result of improved living and health standards, and also due to a high percentage of the birth rate, the world population has increased about 10 times, and for the year 2050 is expected to reach about 10.5 billion. How human action influences the soil and the earth's atmosphere can take many forms and existed since humans began using fire for agriculture, heating and cooking food and especially during the industrial revolution that began at the end of the eighteenth century and early nineteenth century, when air pollution has started to become a major problem. Currently, one of the most serious problems caused by air pollution is global warming produced by the accumulation in the atmosphere large amounts of carbon dioxide and other gases, known as greenhouse gases. They reduce the heat dissipated from Earth but does not block the sun radiation. Because of this greenhouse effect is expected that global temperature increase of 1.4 ° C to 5.8 ° C by 2100, a process that has already begun to change climate patterns, affecting agricultural production, changing the distribution of animals and plants and increasing sea level. To combat the problems posed by pollution worldwide and reducing pollution, an important role it plays on the international stage the policies adopted by governments and international bodies, international understanding and not least nongovernmental groups formed at local, national and international.

Carbon dioxide (CO2) is a colorless, odorless gas that makes up a small fraction of Earth's atmosphere. Despite its inconspicuous nature, CO2 plays an integral part in sustaining life on Earth, a part that is largely unknown or underappreciated by the general public. We present a set of activities designed to help students overcome the most common misunderstandings about CO2, from its sheer existence as a mass-containing molecule to its complementary roles in photosynthesis and respiration. Through these activities, students will be able to apply their knowledge to real-world phenomena, including weight loss and global warming.

Carbon Dioxide Levels

Rising levels of carbon dioxide in Earth’s atmosphere are a problem, because they lead to global warming and changes in climate that are serious threats to the environment we live in. So, getting rid of some of the carbon dioxide would be very important to combat the dangerous effects of global warming. One way to reduce the amount of carbon dioxide in the atmosphere is to turn it into chemicals like methanol. This transformation not only reduces carbon dioxide levels in the atmosphere, but also offers a way to store renewable forms of energy like wind or solar energy.

Radiation Management

This chapter considers solar radiation management, also known as solar geoengineering, which seeks to manipulate Earth’s climate energy balance by reducing the absorption of incoming solar energy. As the chapter explains, this approach spans a class of proposed measures that has been polarizing the community, with some advocating it as an essential means of keeping global warming within acceptable limits, while others see only grave drawbacks and dangers. The chapter describes the two approaches to limiting the absorption of solar energy: measures taken in space, between Earth and the Sun, to reflect or disperse solar radiation before it even hits Earth’s atmosphere; and measures taken in Earth’s atmosphere or at the Earth’s surface to reflect incoming solar radiation. It goes on to discuss the various proposed methods, their potential, and their drawbacks.

A simple experiment has been developed to demonstrate the global warming potential of carbon dioxide (CO 2 ) gas in the Earth's atmosphere. A miniature electric resistance heating element was placed inside an inflatable balloon. The balloon was filled with either air or CO 2 . Whereas the CO 2 partial pressure on the earth's atmosphere is approximately 4 × 10 −4 atm, in this experiment, a high partial pressure of CO 2 (1 atm) was used to compensate for the short radiation absorption path in the balloon. The element was heated to approximately 50°C, the power was then switched off and the element's cooling trends in air and in CO 2 were monitored. It took a longer time to cool the heating element back to ambient temperature in CO 2 than in air. It also took longer times to cool the element in larger size balloons and in pressurized balloons when they were filled with CO 2 . To the contrary, the balloon size or pressure made no difference when the balloons were filled with air. A simple mathematical model was developed, and it confirmed that the radiative heat loss from the element decreased significantly in CO 2 . This investigation showed that the cooling rate of an object, with surface temperature akin to temperatures found on Earth, is reduced in a CO 2 -rich atmosphere because of the concomitant lower heat loss to its environment.

Global warming is one of the biggest environment challenges in front of human today. The earth’s atmosphere and clouds have the function of insulation, making the earth maintain a certain temperature in the night. The earth is in a serious greenhouse effect due to increasing pollution. The paper explains how to deal with and curb global warming.
