Is global warming an urgent danger?

Introduction

A Level Assignment: Is global warming an urgent danger? Humanity and the world have changed drastically since the early civilizations, ranging from the early humans through the Great Pharos to the British Empire. But what has changed so dramatically that it can and will affect us in a negative way now and in the future? No, it is not the advancement in artificial intelligence nor the study and manipulation of DNA. We, humanity, have caused something more serious than any of those, at least at the moment. Global Warming is according to representatives of the National Academy of Sciences "...is the most pressing international issue of the next century" (LBL: 1-2). What is the actual problem of Global Warming? What do we have to do with it? The fact is that nearly everybody is partially responsible for this critical phenomenon. Cheap, plentiful energy has improved our lives, but at a price to the planet (LBL: 1-2). Scientist believe that man made atmospheric changes may result in a global mean temperature rise from 1.5 to 5.5 degrees Celsius by the middle of this century (LBL: 1-2). The fact is that, fossil fuels are used to make energy. Therefore a major problem is the continually growing population, which makes even more energy necessary. Another important fact that is necessary to mention is that according to the LBL Research Review, Carbon dioxide levels are higher than ever. ...read more.

As one can see, Global Warming will not only affect us humans, but also nature in such a dramatic way that one would question our presence in the near future. The causes of Global Warming are well known. Fossil fuels, which are used to make energy, release Carbon dioxide, also known as CO2, which is a greenhouse gas. As sunlight warms the planet, the Earth reflects its own heat energy. The trapped gases block much of that reflected energy from leaving the atmosphere. The trapped energy that heats up the surrounding atmosphere, enveloping the Earth in a cozy blanket of warm air that holds temperatures and climate relatively constant (Issues: 2). Therefore as the amount of greenhouse gases increases, the energy and heat kept in the earth increases too. Through trees getting less out of various reasons, including lack of political action in some countries, and the CO2 increasing, the optimal atmospheric CO2 levels cannot be maintained (LBL: 1). Another problem contributing to Global Warming that humanity has to confront is the rapidly growing global population. As population grows, the energy demand grows logically at the same time. Yet to meet the growing energy demands, we need more power plants, which unfortunately boosts the fossil fuel consumption (LBL: 1). What can we, as members of humanity, do to prevent such catastrophic happenings that are predicted for the future, you may ask. ...read more.

Conclusion

As one can see, Global Warming is an issue that needs to be addressed immediately. If we, humanity, do not act now, we will suffer considerably in the future. This generation may not suffer, it can be our decedents, but this doesn't mean that anybody in this world, on this globe, is off the hook. Every human on this Earth, is partially responsible for what is happening to our mother Earth. Some might be more involved than others. Yet if everybody tries to either limit the use of his car, or stop smoking, or in general give up a few simple things it definitely will make a difference. Now you tell yourself that this is not a realistic plan, or why should I give up something I like to do, for example driving, if others keep doing it. I say, even one person who cares about the environment, the air, the forests, the seas, the rivers, the atmosphere, the soil, his fellow men and everything that is affected by Global Warming can make a difference and surely will motivate others to either join him in his aim or follow in his footsteps. Those who know what Global Warming is about, know its dangerous effects and know that is a major problem that humanity will have to face someday. These people hope that this day, when Global Warming becomes the most important issue, does not come too late. ...read more.
