Global warming essays for your referenceNeed to refer to a few global warming essays to help you write a research paper? Or just find out what it's all about, what's presented in An Inconvenient Truth and other films. These pages provide a big picture, a context for all of the controversy.
Global warming is not new, not exclusive to our lifetimes. Other periods of severe global warming have been followed by ice ages and cooling periods. It happens quite regularly.
The earth has kept together through all of its experiences. The global energy balance at one time may differs a bit from that at other times. How has it affected us over millions of years? It's been a big part of evolution.
One of the basic concepts of air quality is concentration. The amount of something in each volume of air or water. Same as density? Perhaps.
The moment we all have been waiting for. A detailed look at the movie, An Inconvenient Truth, in all its glory. Al Gore put a substantial amount of research into this, and a lot of people have enjoyed cutting it down. If you haven't seen it, you should. Otherwise have a look at this primer.
Info on global warming causesNext, we examine the various things that have been put forward as possible causes of global warming we have witnessed lately. Some, such as carbon dioxide and greenhouse effect are well-known, but here are a few surprises.
Carbon dioxide and its relationship with the global warming discussion. It is a contributor. There are several others which some people choose to ignore, it seems. What are the arguments? What are the solutions?
Everyone seems to have a point of view regarding the effects of global warming on the position of sea level. There shall be more water in the oceans, more heat too. These underlying issues may help you sort out whether the difference in the water's surface level will be greatly affected.
Effects of global warmingOne of the most obvious signs of global warming, as Al Gore likes to point out, is the receding glaciers. An Inconvenient Truth shows images of ice falling off the edge of a glacier, something that happens all the time independent of global warming. Why do we care, really?
For those interested in Canada, its climate or the Koppen Climate Classification system, this page introduces you to all three. It includes a link to the Environment Canada webpage where you get climate norms for any city of your choice.
One of the projected outcomes of global warming is increased drought. Even if precipitation does increase at the same location. How can that be? The answer lies in an increase in potential evapotranspiration (the ability to dry out after it rains) at the same place. It can become drier overall.
Hopefully this collection of global warming essays provides a good set of background knowledge for you, or enhances the expertise you may already have.
